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.
￭ Fill the molecular sieve into the drying flask (4- 2 ).
￭ Screw the filter tube (4- 4 ) on the lower side of the drying flask cover
(4- 1 ) into the opening marked (above) with a dot.
￭ Screw the drying flask cover with mounted filter tube onto the dry-
