Advanced Options for Liquid Loads
More time is required for liquids to reach sterilization temperature
compared to non-liquids. Tuttnauer’s advanced laboratory autoclave
line is equipped with a exible temperature load sensor, which
is placed in a reference vessel, ensuring that the set sterilization
temperature is actually attained when sterilization begins.
Sterilization is initiated only when the load sensor reaches the
preset required temperature.
After sterilization is attained, the autoclave door cannot be opened
immediately, but only after the liquid has properly cooled down.
Tuttnauer’s cooling method prevents a sudden drop in chamber
pressure which can cause liquids to boil over.
An additional challenge is the need to prevent media exposure to
high temperatures for a long time, for the concern that it might
harm the quality of the media. Tuttnauer offers advanced options
that minimize the time liquids are exposed to high temperatures.
Reduced Cycle Times with Optional Fast Cooling
Tuttnauer’s accelerated cooling technology reduces cycle time and
protects the load by minimizing its exposure to high temperatures.
Rapid cooling typically reduces cooling time by as much as 75%.
After sterilization is completed, compressed air is passed through
a microbiological lter into the autoclave chamber. In this way
pressure drops are prevented. The pressure increase prevents load
deformation, cracks or spills.
Fast Cooling Option
Extra Cooling by Water Circulation
The vertical autoclave chamber is surrounded by coils that are lled
with cold tap water to help rapidly cool down the chamber to a safe
temperature. When the liquid’s temperature reaches the nal set
temperature, the cooling stage is complete. The bench-top models
cooling coils are situated in the autoclave chamber, which result in
the same cooling effect.
