Test tubes, culture tubes, there doesn't seem to be a standard term for these standbys of every lab. The plastic tubes are 10 mm in dia. and 75 mm long. The glass are all flint, which means you cannot put them over a flame or heat anything in them. The assortment of glass tubes is from 10 to 14 mm dia x 50 to 100 mm long. We'll give you the best mix that our supplies can produce. Chances are you'll get all of one size in each order.

Lidless, but ready to mount somewhere. It's black plastic and measures 7-1/2" x 4-1/2" x 2-1/4" deep, with a 3/8" wide lip along the short sides with (2) mounting holes in each. Inside it has (4) brass-lined screw holes, (1) in each corner, for attaching the lid it doesn't have, and (5) small circular stand-offs on the bottom. Whatever it was, it's now a mounted tray, component holder, or cover.
