How a supplier gets onto our list, and what it means when they do
A brokerage with no factory is only as good as its research. So the research is published: how the survey was conducted, what each confidence label means, what we deliberately do not verify, and what happens when a supplier cannot deliver. Listing is not endorsement, and we are not paid for placement.
The survey, in numbers
Every figure below is computed from the catalogue file that builds this site. None is typed by hand.
Sourceable entries
Each names candidate suppliers and the evidence for including them.
Categories
From cryopreserved cells through to cold chain.
Verified entries
Re-confirmed against a live primary source on 2026-09-01.
With a published price
A real supplier list price, with its source and capture date on the entry.
Custom RFQ only
No catalogue equivalent exists anywhere. These must be built.
Made by us
We manufacture nothing. This number stays at zero until it does not.
| Breakdown | Entries | Note |
|---|---|---|
| Verified against a primary source | 14 | Live vendor page, storefront API, or vendor technical document on the build date. |
| Partially verified | 11 | Evidenced capability with at least one commercial element not re-confirmed live. |
| Not yet verified | 1 | Constructed from adjacent evidenced capabilities. Requires an RFQ before it can be sold. |
| Partner manufactured | 20 | Produced by a named third-party laboratory to their own published specification. |
| Custom RFQ | 6 | No supplier lists it. Circulated to capable laboratories as a build. |
| In stock | 0 | We hold no inventory in phase one, so this is zero and is shown as zero. |
| Published supplier price located | 9 | A real list price, sourced and dated on the entry. |
| Indicative range held, not public | 1 | Labelled as an indicative range. Never presented as a price. |
| By quotation only | 16 | No public price exists. We will not invent one to fill the column. |
How a supplier gets onto the list
Eight gates. A supplier that fails any of them is either excluded or published with a lower confidence label and a note saying why.
- 01
A real requirement, not a market map
A supplier enters the survey because a buyer requirement pointed at them, or because a gap in the catalogue needed filling. We do not scrape directories or build a list for its own sake. A category with one credible supplier is published with one supplier.
- 02
Primary-source capture
Capability is read from the supplier’s own material: product pages, technical specifications, storefront APIs, published validation papers. Aggregator listings and marketing summaries are recorded as such and never promoted to primary evidence. Every capture carries a date.
- 03
Capability stated in the supplier’s own words
Where the survey says a supplier does something, it is because they say they do it, and the sentence is quoted rather than paraphrased into something more flattering. Where a page could not be fetched, the entry records that the fetch failed rather than filling the gap by inference.
- 04
The kit-versus-finished-good test
The single most misleading thing in this market is a supplier who appears to sell tissue and actually sells the plasticware you cast it in. Every entry is classified explicitly. Two well-known muscle platforms sell the mould, not the muscle, and our catalogue says so on their entries.
- 05
Price evidence, dated and attributed
A price is published only with its source and the date it was captured. Where a supplier holds no public price, the entry says “by quotation” rather than inventing a range. Where we hold an indicative figure that is not public, it is labelled as an indicative range and not as a price.
- 06
Confidence assigned, and published on the page
Every entry carries one of three confidence labels, chosen against a written definition rather than a feeling, and shown on the entry itself. An entry cannot be published without one.
- 07
Provenance assigned from a closed vocabulary
Four labels exist and no fifth will be invented. In phase one nothing carries “In stock” and nothing carries “Made by Wetware World”, because we hold no inventory and operate no production.
- 08
Contact route recorded and re-checked
An entry is only useful if a request can actually reach a human at that organisation. Where a supplier has gone quiet, been acquired, or shut a business line, the entry is corrected. Two organisations in the survey are recorded as closed, and requests are never routed to them.
What the confidence label on an entry means
Three values, shown on every catalogue entry and every datasheet. The definitions are the ones the catalogue file itself uses.
| Label as shown | Entries | Definition | How to read it as a buyer |
|---|---|---|---|
| Verified against a primary source | 14 | Key claims re-confirmed against a live vendor page, storefront API or vendor technical document on the build date. | The supplier exists, sells this, and the figures on our page came from their own current material. Treat the entry as sound and the price as a real anchor. |
| Partially verified | 11 | Claims come from a dated vendor page capture and are consistent across sources, but at least one material element — price, lead time, or willingness to supply — was not re-confirmed live. | The capability is evidenced. One commercial fact is a capture rather than a live read. Expect the quote to move relative to what we published. |
| Not yet verified | 1 | No supplier advertises this as a purchasable offering. Constructed from adjacent evidenced capabilities. Must be validated by an actual RFQ before being sold. | A research lead, not a catalogue item. We believe it is assemblable from named parties. Nobody has yet agreed to build it. |
A confidence label describes our evidence, not the supplier’s competence. A partially verified entry is not a warning about the laboratory. It is a statement about how recently we checked.
Provenance is a separate question
Confidence says how well we checked. Provenance says who makes it. They are not the same field and are never merged.
| Label | Entries | Meaning |
|---|---|---|
| In stock | 0 | Held by a supplier as a catalogue item and shippable against a standing lead time. |
| Partner manufactured | 20 | Produced by a named partner laboratory to their published specification. We arrange supply and quality documentation. |
| Custom RFQ | 6 | No catalogue equivalent exists. We circulate your specification to capable laboratories and return comparable quotes. |
| Made by Wetware World | 0 | Produced in-house. Nothing carries this label, and nothing will until it is true. |
Two things this list is not
Both of these are the difference between a survey and a directory.
Not an endorsement
Listing means capable, not recommended
A supplier appearing on an entry means we found credible evidence that they can do the work. It does not mean we have bought from them, that they have agreed to quote you, that they are the cheapest, or that we vouch for a batch we have not yet seen. Where we have a view on which supplier fits a specific requirement, we will give it to you as a view, attributed to us, with the reasoning attached.
Not paid placement
We survey. We are not paid to list
No supplier pays to appear here, to rank higher, to be described more favourably, or to be recommended. We take no referral fee for placement and no commission that is contingent on which supplier you choose. Our income is the margin or brokerage fee on work you actually order, disclosed on the quotation. Every incentive we have points at the quote being right, not at the quote going to a particular laboratory.
What we do not verify
The limits are published because an unpublished limit is a claim by omission.
- Financial standing, solvency, or how long a supplier will remain in business.
- Internal quality systems beyond what the supplier publishes or documents to us.
- Regulatory or GMP status, which belongs to the supplier and is never ours to assert.
- That a supplier will agree to quote your specific requirement. Willingness is a commercial question and only an RFQ answers it.
- Delivered batch quality on work we have not yet placed. A capability claim is not a performance record.
- Anything on a page we could not fetch. Where an automated fetch was blocked, the entry says so and the confidence label drops accordingly.
When a supplier cannot deliver
Five failure modes and what happens in each. None of them involves waiting for you to ask.
| Failure | What we do |
|---|---|
| A missed acceptance criterion | We restate the criterion, the measurement and the gap in writing, ask the supplier for a remedy, and give you our own view of whether the remedy offered is reasonable. We do not have a stake in a batch being declared acceptable. |
| A missed date | The revised date and the reason are passed on the day we learn them, not on the day they become undeniable. Where the cause is structural — a fixed weekly production cadence, a permit, a courier window — we say that at quotation rather than at delivery. |
| Silence | A supplier who stops answering during a live order is escalated once and then reported to you as non-responsive. Non-response on an RFQ is reported as part of the result, alongside the quotes. |
| A repeated failure | Two failures against the same criterion and the supplier stops receiving our requests. The reason is recorded against the catalogue entry so the same mistake is not made by a different person six months later. |
| A capability that turns out not to exist | Where an RFQ shows a supplier cannot actually do what their page implies, the catalogue entry is corrected and its confidence label drops. That correction is the point of publishing confidence in the first place. |
We publish our sources
Every catalogue entry carries the URLs the claims came from, and they are readable without contacting us.
The evidence sits on the entries rather than in a private file. A datasheet in the catalogue prints its candidate suppliers with the basis for inclusion, the price evidence with its capture date, and a numbered source list linking out to the vendor pages, technical documents and papers the claims were read from.
This is deliberately inconvenient for us. Published sources can be checked, and a checked claim that turns out to be wrong is a correction we have to make in public. That is the trade we are making in exchange for being believed at all.
Correction policy
- A supplier who believes an entry misrepresents them can write to hello@wetwareworld.com and we will correct it against their own published material.
- Corrections change the entry and its confidence label. We do not quietly delete an entry to avoid recording that it was wrong.
- Every entry prints the date its data was current. An undated claim is not a claim.
- Where a fetch was blocked or a page could not be read, the entry says so rather than guessing.
The research is the product until the orders are
26 entries across 9 categories, 14 of them verified against a live primary source on 2026-09-01. If your requirement is not in there, tell us and it becomes the next thing we go and check.
