4-Piece Borosilicate Glass Erlenmeyer Shot Glass Set, 0.8oz/25mL

This set of four Erlenmeyer flask shot glasses is made from lab-quality borosilicate glass. Each glass holds 0.8oz (25mL) and features the classic conical flask shape with a narrow neck and wide base. Borosilicate glass is more durable and heat-resistant than standard soda-lime glass, with tolerance to thermal shock. The glasses should be washed thoroughly before first use. Heat tolerances: strain point 515°C, annealing point 565°C, softening point 820°C.
