Oh Nice. For these colunms the Range Temperature line is 20 - 200ºC.

So the Getter activation range start at 20ºC ??
Very easy for baking tubes in a electric owen.
One has to differentiate between activation ( the hot procedure that boils the
getter material onto the glass) and the longtime work done by the material
that is deposited on the glass.
The later is active at tube working temperature ( 100-200 degrees celcius ) and may be done in an household owen.
