Low Form Borosilicate Glass Weighing Bottle with Ground Stopper

This 20mL weighing bottle is made from borosilicate 3.3 glass and features an interchangeable ground glass stopper. It measures 1.6 inches (40mm) in outside diameter and 1.2 inches (30mm) in height, with an opening diameter of 1.4 inches. The borosilicate construction is autoclavable and offers superior chemical durability with a low temperature gradient, capable of withstanding high temperatures and thermal shocks. Heat tolerances are rated at a strain point of 515°C, annealing point of 565°C, and softening point of 820°C.
