Boiling Flask Flat Bottom 100ml

LBG 3.3 is borosilicate glass with a minimum content in silica of 80% and a low expansion coefficient (3.3?10-6 K-1) included in the 3.3 borosilicate group, as defined in ISO 3585 standard. It is used in products where chemical and mechanical resistance is to be combined with resistance to sudden temperature changes. This particular combination of properties makes this type of glass the most used in labware.Physical and chemical properties:Linear expansion coefficient (@ 20/300 ?C): 3.3?10-6 K-1Strain point: 520 ?CAnnealing point: 560 ? 10 ?CSoftening point: 820 ? 10 ?CDensity: 2.23 ? 0.02 g/cm3Hydrolytic resistance (according to ISO 719, water at 98 ?C): Class 1 Hydrolytic resistance (according to ISO 720, water at 121 ?C): Class 1 Resistance to acids (according to ISO 1776, DIN 12116): Class 1Resistance to alkalis (according to ISO 695): Class 2Typical composition: 80.4% in weight SiO2 13.0% in weight B2O34.2% in weight Na2O 2.4% in weight Al2OProduct More SpecificationsMade InSpainWrite a review Your Name Your ReviewNote: HTML is not translated!
