Clear Glass Boston Round Bottles offer maximum visibility and sample integrity. These general use bottles are perfect for liquids, product storage, and field or plant sampling projects. They feature a round body, rounded shoulders and narrow screw neck opening. These environmentally sensitive bottles help eliminate waste and help to insure product integrity for long term storage. Attached black phenolic (thermoset) caps with pulp/vinyl liners are perfect for general use. The liner is made of a vinyl coating applied to HDPE-coated (high density polyethylene) paper, which is laminated to pulpboard. This general purpose pulp/vinyl liner is commonly used for food, beverage, medical and chemical applications packed at less than 120? F., including mild acids, alkalis, solvents, alcohols, oils and aqueous products; not recommended for active hydrocarbons or bleaches.
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.
