Test tubes - Nitrogen tubes - Schlenk tubes with straight stopcock, with PTFE key

Nitrogen tubes, also known as Schlenk tubes, is a piece of apparatus used

as a reaction vessel in air-sensitive chemistry.

 

It is made of glass and has a side arm fitted with a PTFE or ground glass stopcock which allows the vessel to be evacuated or filled with gas (e.g. nitrogen or argon).

For production of nitrogen tubes, we use Simax borosilicate glass. We allways check glass quality, dimensions and optical clarity.
