Description
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%.
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. However, even minute scratching of glass surface can reduce its thermal resistance. The Strain Point (about 500 DEG C) is generally recommended as the maximum safe operating temperature for United glassware.
