No urine cups, no swab tubes, no culture tubes. Four leaves, four absences.

Urine collection

A wide mouth cup with a leakproof screw lid, often with a transfer device and a volume marked on the side. A specific moulded product, and there is not one on this shelf.

Specimen collection generally

Stool, sputum, tissue. Each has a conventional format with a scoop, a spoon or a preservative already in it, and all of them are made as specimen products rather than adapted from packaging.

Swab transport

A tube with a cap the swab shaft breaks against, usually holding a transport medium. The geometry is matched to the swab, and nothing here is.

Sample vial

Small, often with a septum or a specific cap for an autosampler. An analytical consumable matched to an instrument rather than a container choice.

Two tubes on this shelf

Which is the honest count against four leaves whose conventional format is a tube.

Why a packaging bottle is not a substitute

Volume graduations, sterility, a preservative dosed into the container, and a cap geometry the laboratory's instrument expects. Those are product features, not packaging features.

And the laboratory usually supplies them

Which is the commercial reality. A laboratory that will reject a sample in the wrong tube generally sends the right tube out, so this demand rarely reaches a packaging catalog at all.

Where we are genuinely useful instead

Bulk reagents, buffers, stains, washes and media, in bottles, for a laboratory making up its own. That is 246 bottles doing real work.

And for non-clinical sampling

Environmental and research samples that are not patient specimens. The field sampling property covers the water side of that in detail, including which materials each analyte permits.

Saying it plainly is the service

A clinic looking for urine cups should be told we do not have them, not sold a jar that looks similar. A rejected specimen costs a patient another visit.

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.

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.

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.
