LBG 3.3 is a borosilicate glass with a minimum silica content of 80% and very low expansion coefficient (3,310-6 K-1) belonging to the group of borosilicate type “3.3” as defined in ISO 3585. It is used in products where chemical resistance, mechanical strength and resistance to sudden changes in temperature should be combined, and for this unique combination of properties is the type of reference glass with which most laboratory products are manufactured. Physical and chemical properties Linear expansion coefficient (@ 20/300 oC): 3.310-6 K-1 Recycling temperature (Strain point): 520 oC Annealing point temperature: 560 ± 10 oC Softening point): 820 ± 10 oC Density: 2.23 ± 0.02 g/cm3 Hydrolytic resistance (according to ISO 719, water at 98 oC): Class 1 Hydrolytic resistance (according to ISO 720, water at 121 oC): Class 1 Acid resistance (according to ISO 1776): Class 1 Alkali resistance (according to ISO 695): Class 2 Typical composition 80.4% by weight SiO2 13.0% by weight B2O3 4.2% by weight Na2O 2.4% by weight Al2O3
