The primary function of this TC cylinder is to receive liquids where volumetric calculations are based solely on the volume contained within the cylinder. Among other applications, TC cylinders are frequently used as receivers for the condensate from distillation procedures and sedimentation values of precipitates. Calibrated to contain. Provided with a hexagonal base flat ground for stability and a SAFE-GARD bumper. Ref: ASTM Method D86, D892. Designed from ASTM Specification E1272, Style I, Class B requirements. They meet requirements for the American Society for Testing and Materials (ASTM) E438, Type I, Class A, Standard Specification for Glass in Laboratory Apparatus. Made from 33 expansion borosilicate glass, which has a low coefficient of thermal expansion, very high resistance to chemical attack, and heavy walls that minimize the risk of mechanical breakage when heat is applied. Kimble Chase Life Science and Research Products manufactures scientific laboratory glassware under the Kimble Chase KIMAX brand. The company has its origins in Kimble Glass and Kontes Glass and is now a division of The Gerresheimer Group.
