Maintenance hgis leak rate

Maintenance hgis leak rate

Typical leak rate specifications are less than 60 mTorr/hr for bench-top units, 30 mTorr/hr for pilot-sized freeze-dryers and 15 mTorr/hr for larger production units. Leak rates can also be specified in units of mTorr*L/sec, if the total volume of the system is known. PC-based control systems will often include an automated leak rate test cycle.
