DISPOSABLE GAS MEASURING PIPET

摘要

An apparatus for measuring the rate of gas formation or consumption in chemical or biological reactions in which a gas is evolved or consumed during the reaction is disclosed. The gas measuring apparatus comprises a glass or plastic pipet with constricted openings at both ends, calibrated to read volume or height, and bent at one end through an angle greater than 90 DEG ; a glass or plastic reaction tube, open at one end and sealed at the opposite end and bent at an angle of approximately 90 DEG , thus forming a gas reservoir at the sealed end; and a seal comprising a short length of rubber or plastic tubing fitted over the bent end of the pipet and forced into the open end of the reaction tube.
