Description 250ml 2 neck flat bottom Boiling Flask,24/29 joint,Glass flask,lab glassware 1 Our laboratory glassware is made of 3.3 borosilicate glass. Due to the low linear coefficient of thermal expansion (3.3 x 10^-6/K or 32×10^-7/℃) this borosilicate glass is an ideal choice for fabricating laboratory glassware. It's annealing point is 560℃, and has a softening point of 820℃.
