What we actually stock for this

The shelf, measured
Two hundred and thirty-seven containers from about 15 ml to 946 ml, of which 153 are HDPE and 84 are glass, with 192 closures. The common neck finishes are 24-410, 20-400, 38-400 and 20-410. Both of the main Table II materials are represented in quantity.
What it suits
Reagent decanting and storage, buffer preparation, media, general sample collection where the method does not demand a certified container, teaching labs, and quality control benches inside a manufacturer. That is a large share of real laboratory purchasing.
What it does not suit, and we say so
Certified pre-cleaned containers for trace analysis, pre-preserved sampling kits, and anything rated for cryogenic storage. Those are specialist products with documentation attached, and this shelf is not them. Buying a general bottle for trace metals work is the mistake this paragraph exists to prevent.
Fluoropolymer is a liner here, not a bottle
Where Table II calls for FP, the practical answer on a general shelf is a closure with a PTFE-faced liner rather than a fluoropolymer bottle. That is a real distinction and it is worth checking against your method rather than assuming it satisfies it.
Autoclavable is a question to ask per item
HDPE is not generally autoclavable; polypropylene usually is. If the container has to be sterilized rather than arrive sterile, that narrows the field considerably and it is worth confirming before ordering in quantity.
Neck finish decides the closure
Every container page lists the closures verified against its own neck. In this property the liner inside that closure matters as much as the thread, which is the next section.
Order a sample before committing a case
Fit between a container and the closure you intend, label area, and whether it suits the rack or cooler you actually use are all things one unit answers and a specification does not. For a consumable bought by the case that is a cheap check.
