Test tubes with flange, made from borosilicate (an extremely hard glass), with a high resistance to temperature changes.
Ideal for small drinking cocktails or for serving creative drinks or accompaniment soups.
Appropriate when it is necessary to heat the tubes, even subjecting them to direct flame or else, when they need to be suddenly cooled (even soaking in N2), without risk of breakage.
