The shelf
On this page11
What is here
987 rows: 414 containers and 573 closures. 5 mL to 946 mL with a median of 120. There is nothing above a quart, which fits a classroom.
By material
154 HDPE, 130 glass, 117 PET and 13 PP. The glass is the serious end and the PP is the part that could face an autoclave.
By format
259 bottles and 150 jars, plus 3 jugs and 2 tubes. The jars are the specimen and crystal end; the bottles are samples and reagents.
By size
71 containers at 30 mL or under, 211 at 120 or under, 335 at a pint or under and 394 at a quart or under. The whole shelf sits inside the archetype window for once.
The glass Boston round is the workhorse
78 of them. Small, inert, takes a dropper or a phenolic cap, and the format a stain, a mountant or a reagent belongs in.
The PET single wall jar is the volume answer
101 of them. Clear, light, stackable and cheap, which is what a class set of thirty needs even where glass would be chemically better.
And the straight sided glass jar is the specimen jar
21 of them. The smallest set here and the right object for a preserved specimen, with the breakage objection noted honestly.
Clear versus white
105 clear and 109 white. For a specimen or a crystal the clear wall is half the product; for a reagent that needs protection the 54 amber containers are the answer.
What is absent
Slide boxes, specimen containers as such, and anything we can describe as autoclavable. Three real absences, stated rather than worked around.
How to shop it
Buyer first: a class set or a single unit. Then the chemistry, which decides glass or polyolefin. Then the closure, which for a home is a child resistance decision and for a school is a usability one.
