Reactor Vessel; Cleaning And Sterilization - IKA-WERKE LR 2000 V Mode D'emploi

Reactor vessel

The double-walled glass vessel with a useful volume of 2000 ml is made of borosilicate glass 3.3 DIN-ISO 3585 and has a nomi-
nal width of DN 150. The reactor vessel can be heated up to a maximum temperature of 230 °C via its double-jacket. The double-
jacket-connections are equipped with self-sealing quick-release-couplings. (Two locking nipples are in the accessories kit). A cork
ring for putting down the reactor vessel LR 2000.1 or LR 2000.3 is included in the supply schedule.

Cleaning and sterilization

Cleaning:
The reactor vessel can be completely removed from the reactor so that the internal space is easily accessible for cleaning.
The anchor stirrer, axially held by a circlip, can be withdrawn form the stirring shaft, if required by a slight impact. The teflon
wipers can also be easily drawn off the anchor stirrer thus ensuring a complete cleaning of the stirrer.
If no additional instruments such as ULTRA-TURRAX, thermal sensor or flow breaker are installed, the reactor cover can be scr-
ewed off the stirring shaft bearing for cleaning purposes.
After removing the vacuum connection, use the supplied hooked spanner for loosening the reactor cover. After removing the
ground section parts, the screwed-joints for additional instruments, and after drawing off the protective ring from the stirring
shaft, the reactor cover can be unscrewed from the stirring shaft bearing after the collets have been opened.
Stirring shaft and protective ring can now also be cleaned easily.
If required, all O-rings can be carefully removed with a blunt tool.
Sterilization:
a) Chemical procedure:
By germicides (formaline, phenol, alcohol etc.) many dis-
infection problems can be solved. A subsequent removal
of the remains of the disinfectants is important.
b) Killing germs by moist heat:
Here perched steam with an overpressure of 2 bar
at 120 °C is applied.
c) Killing germs by hot air:
Generally a hot air sterilization is carried out at 160 °C
up to 190 °C.
d) Flamming:
This method can only be applied for indidivual parts
without bore holes as it processes outer surfaces only.
After removing the O-ring sealings, reactor cover, anchor stirrer and other parts can be sterilized by method a), b) or c).
