Transport Sterility Which our catalog cannot speak to The laboratory And they are the ones that reject a sample So ask the laboratory first Many do exactly that Where a packaging catalog does fit And bulk collection for non-clinical sampling Three regimes, one honest answer References

Only one of the three is about the container.

Transport

How the sample gets to the laboratory, which is 49 CFR for a regulated shipment, and the carrier's own rules on top. This is the regime this property is about.

Sterility

Whether the container introduces organisms of its own. For culture media and for microbiological specimen collection the container has to be sterile, with a documented process behind it.

Which our catalog cannot speak to

We record material, capacity and neck finish. We do not record autoclavability, let alone supply a sterilisation certificate, and a container that looks clean is not a sterile one.

The laboratory

What it will accept, how it wants the sample labelled, which tube, which volume, which preservative. Those are the laboratory's rules and they are usually stricter and more specific than the transport ones.

And they are the ones that reject a sample

Most specimens are not lost to a regulator. They are lost to a laboratory rejecting them for the wrong tube, no label, insufficient volume or a broken seal.

So ask the laboratory first

Before the container decision, not after. A laboratory that supplies its own collection kits has already answered every question on this page.

Many do exactly that

Which is the honest commercial observation: a lot of diagnostic container demand never reaches a packaging catalog, because the laboratory ships the kit.

Where a packaging catalog does fit

Culture media and reagents in bulk, in bottles, for a laboratory making up its own. That is a real need and this shelf serves it.

And bulk collection for non-clinical sampling

Environmental, veterinary and research sampling that is not a patient specimen. Our field sampling property covers the water side of that in detail.

Three regimes, one honest answer

We can supply the bottle. We cannot supply the sterility, the system or the laboratory's acceptance criteria, and saying so is more useful than a page of hedged claims.

The archetype behind this shelf is ind-lab: 10 to 1,000 mL, narrow mouth, glass and HDPE, cold fill, thin, aqueous, with "reagent or sample, autoclavability and chemical resistance" as its stated reason. The capacity window fits. Autoclavability is the word that matters most for this craft and our catalog does not record it for any product.

The Davis Pack Supply catalog, measured 19 October 2026. The diagnostics and lab shelf is 600 rows: 270 containers and 330 closures. 5 mL to 946 mL with a median of 118; 71 containers at 30 mL or under, 105 at 60 or under, 154 at 120 or under, 248 at 500 or under. 154 HDPE, 103 glass, 13 PP, and no PET. 246 bottles, 19 jars, 3 jugs, 2 tubes. 97 white, 57 natural, 35 clear, 28 amber. Closures: 163 continuous thread, 44 child resistant, 32 dropper assemblies, 27 spouted, 19 flip top, 14 phenolic, 7 buttress, 6 specialty, 5 dome lids.

Written from 49 CFR 173.199 and 173.134, and from the catalog as it stood on 19 October 2026. Nothing here is offered as a compliant primary receptacle for a regulated shipment: the pressure and drop requirements attach to a tested assembly, not to a bottle. Category A infectious substances are a different packaging instruction entirely and are not summarized. Sterility is not claimed for any product, and what a laboratory will accept is the laboratory's to say.
