5.3 Regenerating or replacing the molecular sieve
NOTICE
Regenerate the molecular sieve regularly.
The intervals at which you have to regenerate the molecular sieve
depends on the humidity in the laboratory and also on the frequency
of use of the instrument.
The molecular sieve filled in the drying flask (2-9) serves to adsorb disrup-
tive oxidizing gases as well as of the water from the aspirated air.
You can regenerate the molecular sieve in the drying oven at
approx. +140 - +180 °C for 24 to 48 h. You can order a new molecular
sieve under the order number 6.2811.000.
CAUTION
Do not fill the hot molecular sieve directly into the drying flask after
regeneration, as otherwise the plastic filter on the filter tube will melt.
Wait until the molecular sieve has cooled down before filling.
