Fisherbrand™ Test Tube Plain 19 mL Without Closure Glass Tube

A plain glass test tube in the classic round-bottom form, this 19-milliliter tube measures 16 by 125 millimeters, ships without a closure, and handles the heating, mixing, and sample-holding of routine nonsterile bench work.

It's a staple for teaching labs and general chemistry benches that go through glassware by the rackful, standing up to repeated washing and reuse. Pair it with a separate closure when samples need to be capped.
