Qubit Flow Meters are simple rotameters used for monitoring gas flow rates in different ranges at a maximum pressure of 14.7 PSI. These flowmeters are precision instruments particularly suitable for metering carrier gases in chromatography, indicating and controlling gases in manufacturing processes, gas flow measurement in laboratories where gas measuring systems for respiration and photosynthesis measurements are employed.....Read More

The G261 Pressure Regulator and Gauge is a Low Volume and Pressure Regulator and it is essential in Accurate Control of System Gas Pressure. It ensures that flow rates set in the gas exchange system remain constant throughout experiments. Setting and maintaining constant system pressure guarantees that sufficient gas is supplied to all sample chambers at the desired flow rate.....Read More

The G262 Blow Off Valve is used to maintain a constant back pressure on the gas delivery system such as Gas Mixing System. The blow off gas pressure is set above the Pressure Regulator's level and a small amount of gas is constantly blowing off (venting). The flow rate of gas from the gas mixing system is set slightly above the total common manifold flow rate to.....Read More
