Beakers, Heavy Duty
Heavy duty beakers are ideal for tough handling conditions including mechanized washing. Beakers feature a double graduated metric scale and a marking area. Tolerance is approximately ± 5%.
Properties of Borosilicate Glass: Our glassware is manufactured from low-expansion Type 1, Class A Borosilicate 3.3 glass that complies with ASTM E438 Standard Specification for Glasses in Laboratory Apparatus. Borosilicate glass has a low coefficient of thermal expansion. Therefore, the thermal stresses under a given temperature gradient are low, and the glass can withstand higher temperature gradients, as well as sudden temperature changes (thermal shocks). The “strain point” of borosilicate glass is about 500C and it is recommended as the maximum safe operating temperature. The glass may acquire permanent stresses upon cooling if heated about 500C.
