Faster leak testing

Establish stable pressure for the leak check by measuring pressure precisely at the device under test with Alicat’s PC3-Series pressure controller with remote sense port. This method negates the pressure drop induced by the mass flow meter that is measuring the leak rate with 5-ms speed of response.

Monitoring and recording bioreactor output

Applications like methane production or hydrogenation benefit from comparing the mass of gas added to the bioreactor with the mass that has been outgassed. When outgassing occurs at atmospheric pressures, the very low pressure drop of Alicat’s Whisper-Series will not induce backpressure while quantifying outgassed mass.
