Description:

Ø16 mm, round bottom.  

Test tubes with support. Ideal for small cocktails, serving tea or soup accompaniment. Made of borosilicate glass, similar to Pyrex, extremely strong with high resistance to sudden temperature changes. Ideal when you need to heat the tubes in direct flame or even when you need to cool them quickly (even submerged in N2) without risk of breakage. Its rounded edge finish gives the tube a high resistance to breakage and ensures guests safety.
They come WITHOUT cork cap. You can order it apart (ref.100/0054). Don’t forget to buy a cleaning brush.
