Sterilization
in the autoclave
(“autoclaving”)
Preferable procedure: to autoclave containers and medium separately.
This way, PP containers perfectly keep their shape and can be
used an infinite number of times over and over again:
· pack stapled containers and lids
separately in an autoclavable wrapping
· fill containers under LAF with warm
sterilised medium
· click to close lid brims all around
· keep containers with medium in a well
ventilated room
Corner
of lid left open:
no deformation.
gas has free passage
Hermetically
closed lid:
containers garble with pressure changes.
quick pressure increase or reduction
Alternative
procedure:
to autoclave containers with medium, the following
procedures avoid that the containers are deformed or
burst while autoclaving.
· fill containers with
medium
· place
the lids on containers,
· press
gently along 3/4 of surface
· leave one border of lid
open
After sterilisation, slowly reduce
the
pressure in the autoclave back to atmospheric pressure.
Immediately after emptying the autoclave, click to close the lids all
around and keep containers with medium in a well ventilated
room.
Gas
exchange
By means of diffusion throughout a series of depth filters. The gas
exchange is optimal in the following conditions:
· keep the filter zones free of labels
or any other object
· keep the filters well dry:
· before re-using
the lids, clean them by means of a moist cloth (do not soak!)
· leave a border of
the lid open during sterilisation (see above)
· dry accidently wet
filters in circulating air
· choose the suitable filter type (L,
XL, XXL, XXL+) and adjust ventilation ratio in order to obtain
an
ideal gas exchange in combination with a
minimal dose of deshydratation
