Using an Inert Gas Atmosphere
Many samples experience oxidation at elevated temperatures—an atmoshere of inert gas such as nitrogen or
argon can be used to prevent this. The gas supply should be regulated to less than 40 psi (2.8 bar) before
connection to the Upper Heated Plate. A gas flow meter (not supplied) should be used to set the gas flow rate.
1.
Connect the gas supply to the inlet port on the gas flow meter.
2.
Connect the outlet port on the flow meter to the inert gas inlet port on the Upper Heated Plate using 4-mm
outer diameter tubing (white) and the connector provided.
3.
Set the inert gas flow rate at 1 Liter per minute (L/min). If the gas flow rate is set too high, temperature
control of the Upper Heated Plate may be affected.
