Reed Diffuser Bases × Samples Before Wholesale
On CSI the sample is the listed 500 ml. Two candidate bases cost 4.0% of a 25 kg order at listed prices — and tell you whether the base works with your oils. They cannot tell you whether the 25 kg will match, so keep a retained sample and check the delivery.

CSI materials for a two-base, two-oil sample round — Lift and Pure Performance 500 ml, Blue Ocean, Fresh Strawberries, 50 ml bottles, reeds · CSI live pricing, pulled 14 October 2026
Quick answers — read this first
Should I sample before a 25 kg base order? Yes. Two 500 ml samples are ₹2,198.00 against about ₹54,950.00 for 25 kg at listed prices — 4.0%.

Does CSI sell 500 g samples? Every in-stock base is listed in 500 ml; Pure Performance also in 100 g. That listed size is the sample. There is no 25 kg listing — ask for a quote on WhatsApp.

Is 500 ml enough to test? Yes: nine 50 ml test bottles per base use 302.4 g, leaving a retained sample and a repeat.

What can a sample not tell me? Whether the 25 kg will be the same lot, the dispatch time, the pack format or reorder availability — none is published. Ask, and check the delivery.
The short answer
Answer: Yes. Buy one 500 ml of each candidate base (CSI's listed size), test it with every oil the 25 kg is for, keep a retained sample, get the 25 kg quote and commercial details in writing, and check the delivery against the retained sample.
Why: Sampling costs about 9.9% of the order with oils, bottles and reeds; it pays if there is more than a 9.9% chance the untested base would be wrong for your oils.
Method: Per base: three reeded bottles per oil at 20%, a blank and a 30% clarity stress bottle per oil — nine 50 ml bottles from one 500 ml; clarity to 7 days, weights and blind scores to day 14.

Straight answer
Should I purchase 500 g samples of different reed diffuser bases before committing to a 25 kg wholesale order?
Yes — and on CSI the sample is simply the listed size. Every in-stock CSI reed diffuser base comes in 500 ml (Pure Performance Base also in 100 g); there is no 25 kg listing, and 25 kg is roughly 50 × 500 ml at an example 1.00 g per ml — weigh 100 ml to know yours. Two candidate samples cost ₹2,198.00, about 4.0% of the ₹54,950.00 that 25 kg would cost at listed prices; a full sample round with oils, bottles and reeds is ₹5,461.04. One 500 ml is enough for nine 50 ml test bottles per base — three per oil for two oils, a blank and a 30% clarity stress bottle per oil — with some left as a retained sample. A sample tells you whether the base works with your oils; it cannot tell you whether the 25 kg will be the same lot, when it will ship or in what pack — ask for those with the quote, and check the delivery against your retained sample before production.
One line: sample two, test every oil, keep a retained bottle, check the 25 kg when it lands.
On CSI, the sample is the listed size: every in-stock reed diffuser base comes in 500 ml, and Pure Performance Base also in 100 g. There is no 25 kg listing; a 25 kg order is roughly 50 × 500 ml at an example 1.00 g per ml and is quoted on WhatsApp. For aquatic and fruity oils, the page-matched candidate is Lift Base (₹1,099.00), tested against neutral Pure Performance.
See Lift Base

Yes — sample first. Here is what it costs and what it cannot tell you

A 25 kg order of the wrong base is not a saving at any price. A pair of 500 ml bottles is the cheapest insurance you will buy this year.

The short answer is yes, and the arithmetic makes it easy. At CSI's listed price, 25 kg of a ₹1,099.00 base is 50 bottles of 500 ml at an example density of 1.00 g per ml — ₹54,950.00 before any quoted volume price. One 500 ml of each of two candidate bases is ₹2,198.00, about 4.0% of that. With oils, bottles and reeds to test them properly, the full sample round on this page is ₹5,461.04, or 9.9% of the order. If there is more than a 9.9% chance that a base ordered without testing would turn out unusable with your oils — leaving you with 25 kg you cannot sell — the sample round pays for itself; with a new base and new oils, the chance is rarely that small.

But a sample answers some questions and not others, and it is worth being clear which before you treat a good sample result as permission to buy 25 kg. A sample tells you whether this base, with your oils, at your load, in your bottle, stays clear and performs. It cannot tell you whether the 25 kg you receive will be the same as the sample: CSI publishes no lot numbers, lot-to-lot data or batch certificates for its bases, so a large delivery may come from a different production lot. Nor does a sample tell you lead time, the packing format of a large quantity, or whether the base will be in stock when you reorder — none of which is published. Ask CSI on WhatsApp about each, and check the delivery when it arrives.

So the straight answer is: buy one 500 ml of each candidate base (100 g of Pure Performance if you only need a first clarity screen), test it with every oil you will use it for, keep a retained sample of the one that passes, ask for a quote and the commercial details for 25 kg, and check the delivery against your retained sample before blending production. The rest of this page sizes the sample round so one bottle of each base is enough, prices it, and gives you the arrival check.

The CSI principle
Sample the base you will buy, with the oils you will sell, before the order you cannot undo.
And keep some of the sample. The retained bottle is the reference your 25 kg delivery is checked against.

Is 500 ml enough? Budgeting one sample bottle

It is, if you plan it. In CSI's 50 ml Gold Reed Diffuser Bottle with an example 40 g fill at 20%, each test bottle uses 32 g of base. A useful round per base is three reeded bottles per oil for two oils, a base-only blank, and one bottle of each oil at 30% — the top of the pages' range — as a clarity stress check. That is 9 bottles and 302.4 g of base with a 5% allowance, leaving about 198 g of the 500 ml (at the example density) for a repeat or a second load.

Per candidate base · 40 g fill · production load 20% · stress check 30% · 5% allowance
Where one 500 ml goes
Use Bottles Base each Base total
Blue Ocean at 20%, reeded 3 32 g 96 g
Fresh Strawberries at 20%, reeded 3 32 g 96 g
Base-only blank, capped 1 40 g 40 g
Each oil at 30%, capped (clarity stress) 2 28 g 56 g
5% allowance — — 14.4 g
Total 9 302.4 g
Left in the 500 ml for a repeat (example 1.00 g/ml) — — 198 g

If you are not yet sure a base is worth a 500 ml, a smaller clarity screen comes first: one bottle of each oil at 20% plus a blank needs 109.2 g of base, which Pure Performance Base's 100 g size covers (2 × 100 g, ₹650.00). The other four bases are sold only in 500 ml, so for them the 500 ml is the smallest sample there is. Clarity tests before a 5 kg order gives the full seven-look clarity protocol, and comparing two bases on five criteria gives the scorecard to read this round with.

Test every oil the 25 kg is for
A 25 kg base order usually serves a whole range. The sample round has to include every oil you plan to put in it — a base that passes with your fruity oil can fail with your aquatic one. If the range is larger than two oils, budget more bottles from the sample, or buy a second 500 ml of the candidate that looks strongest after the clarity checks. One base for four different oils? explains why every pair is its own test.

The sample round: two bases, two oils, one 500 ml each

The candidates here follow what CSI's pages say. Lift Base's page is written for floral, citrus, green and fruity families, and Longevity Base's page tells you to use Lift for aquatics; the example oils are Blue Ocean (aquatic) and Fresh Strawberries (fruity). Pure Performance Base is the neutral control, and if you already sell in another base, make that the control instead. Every bottle is weighed; every room score is blind.

Paper firstAsk CSI on WhatsApp whether an SDS or technical data sheet is available for each candidate base, and for the IFRA certificate of each oil; read each oil's limit for the category covering reed diffusers before you settle the load. The SDS and technical data sheet checklist says what to read.
2
Weigh 100 ml of each base on arrival, and keep itOn the Weighing Scale, tared, three times, averaged. Pour that 100 ml into a clean, labelled, capped bottle and keep it in a cool, dark place: it is your retained sample, and the figure decides how many 500 ml bottles your 25 kg really is.
3
Mix, gate on clarity, restBy weight, per oil and base. Check every blend, the blanks and the 30% stress bottles against white and black cards at 0 h, 24 h and 48 h — the pages' rest — and again at 7 days and after a cool night. A 30% bottle that hazes is not a fail at 20%, but it tells you how much margin you have.

Reed, weigh and score7 reeds in each reeded bottle; weigh for day 0; one flip time for all bottles; weigh on days 1, 3, 7 and 14; blind 0–5 room scores on days 1, 7 and 14.
5
Decide, then ask for the commercial detailsScore with your written scorecard. For the winning base, ask CSI on WhatsApp for a quote for 25 kg, the packing format, the expected dispatch time and whether the quantity can be supplied together — then decide. None of these is published, so get them in writing.
The common mistake: sampling one base and calling it a comparison. A single base tested alone can only pass or fail; it cannot tell you whether a different base would have been better for the same money. With four CSI bases at the same 500 ml price, one extra sample bottle is a small cost against a 25 kg decision. Fix: always sample at least two candidates — the page-matched base and a neutral control, or your current base — side by side.

From the sample to the 25 kg order

A good sample is permission to ask for a quote — not a reason to stop checking.

Before you order, size the whole job, not just the base. At 20% in a 40 g fill, each bottle holds 32 g of base, so 25 kg of base makes about 781 bottles and needs 6,250 g of fragrance oil — 6.25 kg — alongside it. CSI's oils are listed up to 1 kg per pack, so plan the oil order with the base order, and check each oil's stock: on 14 October 2026 Blue Ocean was in stock from 15 g to 1 kg and Fresh Strawberries likewise. The bottles and reeds scale the same way: about 79 packs of ten bottles and 5,469 reeds at 7 per bottle — see how much base for 100 bottles and monthly wholesale requirements and lead times for the full order maths.

Questions for the quote
Question Why it matters
What is the price for about 25 kg, and in what pack format? No 25 kg listing and no published volume discount; the quote replaces the 500 ml arithmetic
Can the quantity be supplied from one production lot? So your whole run matches the sample you approved — do not assume it
When can it be dispatched? Lead times are not published; plan festive production backwards from the answer
Is an SDS available for this base, current version? Storage, labelling and courier needs for 25 kg in your workshop
How should an opened large pack be stored? A 25 kg pack is used over weeks; shelf life is not published
Will this base be available for reorder? A 25 kg commitment assumes you can buy the same base again
Do this when the 25 kg arrives · against your retained sample · before any production blend
The arrival check
Check How Pass if
Record Date, packs received, any marking on the packs —
Weight per 100 ml Same method as the sample Within a few grams of the sample's figure
Look and smell New base beside retained sample, white and black cards; blind sniff Same clarity, colour and odour
Quick ladder Each oil at production load and +10 points, 0 h, 48 h, 7 days Clear, as the sample was
Pilot bottles Three bottles of your bestseller, weighed for 7 days g/day and room score in line with the sample round
Argued against our own interest, plainly. A 25 kg order is the kind of sale any supplier wants to close quickly. But if neither sample passes with both your oils, the right order from us is not 25 kg of the better of two failures; it is another 500 ml of a third candidate, or nothing. And if your current base passes as well as ours, keep it — a ₹54,950.00 switch should buy you something your scorecard can see.

The priced sample round

Listed, in-stock CSI packs only, with a 5% allowance on liquids. One 500 ml of each base is the sample itself. Each oil needs 75.6 g across both bases (3 bottles at 20% and one at 30% per base), bought as the cheapest mix of its small sizes. Two packs of 50 ml bottles cover the eighteen bottles with two spare.

Pure Performance's sample could be bought as 100 g packs instead — the round needs 302.4 g, which is 1 × 500 ml (₹1,099.00) — but the 500 ml is cheaper per gram for any density above 0.676 g per ml and leaves a retained sample and a repeat. The 84 reeds come as one 100-pack (₹800.00), cheaper than a 50 and two 25s (₹872.00).

Working decision rule · after the 7-day (ideally 14-day) readings · one action per line
Order, sample again, or wait
If this is true It means Do this
A base passes clarity with every oil and wins or ties your scorecard A candidate for the order Ask for the 25 kg quote and commercial details; keep the retained sample
It passes at 20% but a 30% stress bottle hazes Compatible, limited margin Order only if your production load stays well below the haze point
It passes with one oil, fails with another Not a range base Order for the passing oil only, or sample a third base for the other
Both candidates fail with an oil Neither suits that oil Don't order yet — sample another base
Your current base ties with the candidates No reason to switch Don't order a new base
Quote, lot, dispatch or SDS answers do not fit your plan A commercial gap Order in 500 ml for now; revisit the 25 kg later

Once ordered, the 25 kg is checked on arrival against the retained sample, and the retained sample is kept until the last bottle of that delivery is sold. Should I buy 1 kg, 5 kg or 25 kg of base when starting? weighs the quantity itself; choosing a base supplier for consistency and repeat availability and testing a new base supplier before switching cover the supplier side; scaling a 100 g trial to 25 kg production covers the formulation side. The section's pillar is which reed diffuser base to buy in India, and its capstone is the commercial base selection framework.

Two sample bottles are a rounding error on a 25 kg order. The wrong 25 kg is not.

Why trust this guide

CANDLEMAKINGSUPPLIESINDIA supplies raw materials, not finished diffusers. A supplier could skip straight to the 25 kg quote. This page says the sample is worth it, says plainly that CSI lists no 25 kg size, publishes no volume discount, lot numbers, lead times or pack format for large quantities, and tells you not to switch from a base that ties with ours.

Diffuser base, reed, bottle and tool prices are CSI live pricing, pulled 14 October 2026. Fragrance-oil prices are CSI live pricing, pulled 24 September 2026, stock re-checked 14 October 2026. Every blend split, base-pack count, per-bottle liquid cost, kit total and cost per day on this page is computed and shown to two decimals so you can check it; density and grams-per-day figures are labelled examples, never CSI specifications.

Bottle counts per arm, the clarity checkpoints, the weighing schedule, the room-scoring scale and the decision thresholds are labelled working practices, not industry standards — none exists for reed diffusers. The 40 g fill, the 20% production load, the 30% stress check, the density examples and the break-even probability are labelled examples or arithmetic you replace with your own.

Frequently asked questions

Should I test reed diffuser base before buying in bulk?
Yes. Buy the smallest listed size of each candidate, test it with every oil you will use it for — clarity, weighed grams per day and blind room scores — and keep a retained sample to check the bulk delivery against.
How many diffusers can I test with 500 ml of base?
In 50 ml bottles with a 40 g fill at 20%, each bottle uses 32 g of base, so 500 ml (about 500 g at 1.00 g per ml) covers nine test bottles with a 5% allowance and leaves about 200 g for a repeat.
How many 500 ml bottles make 25 kg of diffuser base?
It depends on density: at 1.00 g per ml, 50 bottles; at 0.95 g per ml, 53; at 1.05 g per ml, 48. Weigh 100 ml of the base to find yours.
Does CSI sell reed diffuser base in 25 kg?
There is no 25 kg listing. Bases are listed in 500 ml (Pure Performance also in 100 g); larger quantities are quoted on WhatsApp and no volume discount is published.
Will a bulk order of base match my sample?
Not guaranteed. CSI publishes no lot numbers or lot-to-lot data. Ask whether the quantity can be supplied together, keep a retained sample, and check the delivery's weight per 100 ml, clarity, odour and a quick load ladder before blending production.
How many reed diffuser bases should I sample?
At least two: the base whose page is written for your fragrance family and a neutral control, or your current base. With four CSI bases at the same 500 ml price, an extra sample costs little against a bulk decision.

About this guide: Written by the CANDLEMAKINGSUPPLIESINDIA team. The sampling budget, sample round, quote questions, arrival check and decision rule apply to any base from any supplier; the products named are CSI's. 25 kg and 500 g are the reader's figures; CSI lists bases in 500 ml (Pure Performance also 100 g).

Customer reviews: The six reviews at the top of this page are genuine, published Judge.me reviews left by CSI customers on the product pages named on each card — Eco Candle Wicks, Premium Candle Wicking Needle and Bamboo Wick Holder. They are general product reviews, not assessments of the guidance set out here. Names, star ratings, dates and products are as recorded by Judge.me and wording is unedited. "Verified buyer" appears only on the three reviews Judge.me recorded as verified — Monika Deep, Subhankar Roy and Sneha Tamang; the reviews from Ashwini, LJ and Lalitha Jagan are published but not recorded as verified, and carry no badge.

Non-price figures and assumptions: Load convention: fragrance load is a share of the total blend by weight (oil g = blend g × L; base g = blend g × (1 − L)). Example fill 40 g per 50 ml bottle at 20% = 8 g oil + 32 g base; clarity stress at 30%. Example density 1.00 g per ml with ±5% sensitivity for converting 25 kg into 500 ml bottles. Working practices: per base, 3 reeded bottles per oil, 1 base-only blank, 1 stress bottle per oil; 7 reeds; 5% liquid allowance; clarity at 0 h, 24 h, 48 h, 7 days and after a cool night; weights on days 0, 1, 3, 7 and 14; blind 0–5 scoring on days 1, 7 and 14. The break-even probability is the sample round's cost divided by the 25 kg order value at listed prices. What CSI's base pages state (quoted as claims to test, not CSI test results): Pure Performance — neutral, "no added fixatives, no complex enhancements", for all families, start at 10%, maximum 30%, 20% recommended, typical working blend 75% base + 25% fragrance, rest 24–48 hours, flip reeds after the first hour; Longevity — oriental/amber, woody, resinous/balsamic, spicy and gourmand families, slower "cold diffusion", 10–30%, "if clouding occurs, reduce fragrance percentage and retest", allow 2–3 hours before the first flip; Lift — floral, citrus, green and fruity families, 10–30%; Depth — chypre, leather, smoky and rich gourmand, "slow diffusion", 10–30%; Softness — soft florals, powdery/musky and light gourmand, 10–30%; all five say rest 24–48 hours and describe themselves as crystal clear. Fibre reed page: length 20.3 cm; 6–8 reeds for a standard 50–100 ml bottle, more for stronger and faster diffusion, fewer for subtler and longer-lasting. CSI publishes no composition, density, viscosity, evaporation rate, flash point, shelf life or SDS figure for any diffuser base; no throw, evaporation or longevity data for any base, oil or reed; no reed diameter; no bottle neck size or fill line; and no IFRA limit for any oil. Any density on this page is a labelled example the reader replaces with a weighed figure; any g/day is a labelled example the reader replaces with a measured one. Material costs exclude labour, labels, boxes, freight and GST. Diwali 2026 falls on Sunday 8 November.
