Ö
Water post-feed
With the Water post-feed option, water is led within the jacket space not only
prior to sterilization, but more water is added as needed from the feed water
tank. In this manner, it is possible to implement sterilizing and steaming
times of up to 10019 minutes.
Ö
Batch documentation
With this option, the sterilizer is additionally equipped with an
integrated
printer
for batch documentation. The integrated printer can operate in
parallel
with any program
. The printout logs the sterilization process
complete with date, batch number and sterilization parameters, as well as
any errors that have occurred during program execution.
A possible alternative is using the
VARIOSOFT
PC software for batch
documentation.
4.2 Special
programs
Ö
Climatic chamber
The benchtop sterilizer can be reprogrammed to serve as climatic chamber
for long-term ageing tests. This requires the presence of certain expansion
options.
The sterilizing time of all available programs must be set to
∞
(infinity). Any
program selected and executed must then be terminated manually. The feed
water tank (4) level must be checked at regular intervals.
Ö
Multiple sterilization
The benchtop sterilizer can be reprogrammed for multiple sterilization for
testing. This means that the complete sterilization cycle is executed several
times in succession. The number of cycles can be selected. This requires
the presence of certain expansion options. The feed water tank (4) level
must be checked at regular intervals.
4.3 Safety
features
The VARIOKLAV Type 25 T benchtop sterilizer has various safety features,
including simple handling thanks to automated program control, which reduces the
number of operator errors, and a sophisticated error management system that
monitors and reports technical problems or defects. The enclosed diagram gives
you an overview over structural and programmed safety features.
4.3.1 Exhaust air filtration (Types FA, FA/FS)
The steam sterilizer may be equipped with a
sterile air filter
(Type FA expansion
option) as an additional safety feature. The exhaust air filtration system prevents
the escape of micro-organisms from the sterilizer during deaeration. This is
necessary for safe and emission-free sterilization of contaminated materials,
