Figure 5 Filling the adsorber tube
1
Insert a small cotton plug into the bottom of the adsorber tube. Do
not pack the cotton too tightly.
2
Fill the adsorber tube to ¾ with molecular sieve granulate.
3
Place a small cotton plug on the molecular sieve. Do not pack the
cotton too tightly.
4
Seal the adsorber tube with the appropriate cover.
NOTICE
Note that the molecular sieve must be replaced at regular intervals.
Each time you refill the adsorber tube with the molecular sieve, you
can, for example, write the date directly on the adsorber tube.
