Over the course of a beamtime it is highly likely that you will need to replace the gas bottles

The PCO gas (Argon Technical Grade) should flow at 1.7 SCCM

The KB Gas (BIP Helium) should flow at 3.5 SCCM

Check regulators on the bottles themselves.

If gas has run out call EHC’s to replace (8787) – let them know which gas and which grade (Argon – Technical, Helium – BIP).
