Method · Published in full
Sourcing methodology
How the survey was conducted, what each confidence label means, the limits of verification, and what happens when a supplier cannot deliver. Listing is not endorsement. No payment is taken for placement.
Survey figures
Computed from the catalogue file that builds this site.
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 supplier list price, with its source and capture date on the entry.
Custom RFQ only
No catalogue equivalent exists. These must be built.
Made by Wetware World
Entries produced in-house to our own specification.
| Breakdown | Entries | Note |
|---|---|---|
| Verified against a primary source | 42 | Live vendor page, storefront API, or vendor technical document on the build date. |
| Partially verified | 22 | Evidenced capability with at least one commercial element not re-confirmed live. |
| Not yet verified | 2 | Constructed from adjacent evidenced capabilities. Requires an RFQ before it can be sold. |
| Partner manufactured | 54 | Produced by a named third-party laboratory to their own published specification. |
| Custom RFQ | 12 | No supplier lists it. Circulated to capable laboratories as a build. |
| In stock | 0 | Held by a supplier and shippable against a standing lead time. |
| Published supplier price located | 34 | A list price, sourced and dated on the entry. |
| Indicative range held, not public | 7 | Labelled as an indicative range. |
| By quotation only | 25 | No public price exists; the figure comes back with the quote. |
Inclusion gates
A supplier that fails a gate is excluded, or published with a lower confidence label and a note.
- 01
Inclusion trigger
A supplier enters the survey because a buyer requirement pointed at them, or because a gap in the catalogue required filling. Directories are not scraped. 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 are not treated as primary evidence. Every capture carries a date.
- 03
Capability quoted from the supplier
Capability claims are quoted from the supplier’s own wording. Where a page could not be fetched, the entry records the failed fetch.
- 04
Kit versus finished good
Every entry is classified as a kit or a finished good. Two muscle platforms in the survey sell the mould rather than the muscle; their entries state this.
- 05
Price evidence, dated and attributed
A price is published only with its source and capture date. Where a supplier holds no public price, the entry reads “by quotation”. A non-public indicative figure is labelled as an indicative range.
- 06
Confidence label assigned
Every entry carries one of three confidence labels, assigned against a written definition and shown on the entry. An entry cannot be published without one.
- 07
Provenance assigned from a closed vocabulary
Four labels cover the catalogue, each defined below and assigned from the supplier evidence on file.
- 08
Contact route recorded and re-checked
Where a supplier has stopped responding, been acquired, or closed a business line, the entry is corrected. Two organisations in the survey are recorded as closed and receive no requests.
Confidence labels
Three values, shown on every catalogue entry and datasheet.
| Label as shown | Entries | Definition | Buyer reading |
|---|---|---|---|
| Verified against a primary source | 42 | 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 came from their own current material. |
| Partially verified | 22 | 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. At least one commercial fact is a dated capture rather than a live read. The quoted figure may differ from the published one. |
| Not yet verified | 2 | No supplier advertises this as a purchasable offering. Constructed from adjacent evidenced capabilities. Must be validated by an actual RFQ before being sold. | Assembled from the capabilities of named parties. No supplier has agreed to build it. |
A confidence label describes the evidence held, not the supplier’s competence.
Provenance
Confidence records the evidence held. Provenance records who makes the item. They are separate fields.
| Label | Entries | Meaning |
|---|---|---|
| In stock | 0 | Held by a supplier as a catalogue item and shippable against a standing lead time. |
| Partner manufactured | 54 | Produced by a named partner laboratory to their published specification. We arrange supply and quality documentation. |
| Custom RFQ | 12 | No catalogue equivalent exists. We circulate your specification to capable laboratories and return comparable quotes. |
| Made by Wetware World | 0 | Produced in-house to our own specification. |
Scope of a listing
Not an endorsement
Listing indicates capability, not recommendation
A supplier on an entry means credible evidence exists that they can do the work. It does not mean they have been bought from, that they have agreed to quote, or that they are the lowest price. Where Wetware World holds an opinion on supplier fit, it is given as an attributed opinion.
Not paid placement
No paid placement
No supplier pays to appear, to rank higher, to be described more favourably, or to be recommended. No referral fee is taken for placement and no commission is contingent on supplier selection. Income is the margin or brokerage fee on work ordered, disclosed on the quotation.
Not verified
- 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 is the supplier’s to assert.
- That a supplier will agree to quote your requirement. Only an RFQ establishes this.
- Delivered batch quality on work not yet placed.
- Content on pages that could not be fetched. Where an automated fetch was blocked, the entry records it and the confidence label is lowered.
When a supplier cannot deliver
Five failure modes and the handling of each.
| Failure | What we do |
|---|---|
| A missed acceptance criterion | The criterion, the measurement and the gap are restated in writing. The supplier is asked for a remedy and our assessment of that remedy is provided. |
| A missed date | The revised date and the reason are passed on the day they are known. Structural causes such as a fixed weekly production cadence, a permit or a courier window are stated at quotation. |
| Silence | A supplier who stops answering during a live order is escalated once and then reported as non-responsive. Non-response on an RFQ is reported alongside the quotes. |
| A repeated failure | Two failures against the same criterion end further requests to that supplier. The reason is recorded against the catalogue entry. |
| A capability that does not exist | Where an RFQ shows a supplier cannot perform the work their page describes, the catalogue entry is corrected and its confidence label is lowered. |
Sources
Every catalogue entry carries the URLs the claims came from.
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.
Correction policy
- A supplier who believes an entry misrepresents them can write to [email protected]. The entry is corrected against their own published material.
- Corrections change the entry and its confidence label, and are recorded.
- Every entry prints the date its data was current.
- Where a fetch was blocked or a page could not be read, the entry records it.
Catalogue
66 entries across 9 categories, 42 of them verified against a live primary source on 2026-09-01. Requirements not covered can be submitted for research.
