Safety

Your safety is an important factor. Tuttnauer autoclaves provide safety features that ensure a trouble free work environment.

Door Safety

The laboratory autoclaves are designed with a number of independent mechanical and digital safety features.

A safety device prevents the operator from opening the door when the chamber is pressurized
A safety device prevents the operator from opening the door when the chamber is pressurized
Steam will not to enter the chamber when the door is open
A cycle cannot start if the door is open or not properly locked
he door cannot unlock until liquid temperature reaches the predetermined end temperature
The door cannot unlock until chamber pressure reaches room pressure

General Safety Features

Double Independent Monitoring: The combined electronic and mechanical monitoring ensures that the operator has two independent means to monitor pressure
Safety Valves: The chamber is equipped with safety valves – if the pressure exceeds the allowed limit the safety valves will discharge
Built-in Steam Generator Safety: A water level monitoring system maintains a constant water level and ensures safe operation of the heaters

Liquid Loads

Liquid Load Fast Cooling Applications

Sterilizing liquid requires longer heating and cooling times for completing a cycle, especially with sensitive liquid loads.
When time is critical advanced optional fast cooling features are available with Tuttnauer’s laboratory autoclaves that prevent a sudden drop in chamber pressure which can cause liquids to boil over.

Fast Liquid Cooling

After sterilization is completed, compressed air is passed through a microbiological filter into the autoclave chamber in order to prevent a drop in pressure which also prevents load deformation, cracks or spills. Cold water is then circulated through cooling pipes that rapidly reduces the chamber temperature and that of the liquid load to a safe temperature.

Tuttnauer’s fast liquid cooling technology reduces cycle time by as much as 75% and minimizes load exposure to high temperatures.

Super Fast Liquid Cooling

In addition to fast cooling, an optional fan can be applied to further circulate the compressed air in the chamber.
This speeds up the heat exchange during the cooling stage in order to safely achieve super fast cooling of the liquid load under pressure.

Tuttnauer’s accelerated fast liquid cooling technology reduces cycle time by as much as 90% and minimizes load exposure to high temperatures.

Glassware, Hollow and Tip Applications

Efficient air removal is an important requirement for sterilizing hollow loads such as laboratory glassware and tips where the standard gravity displacement air removal method is not effective. Air removal after sterilization also assists in fast drying of your laboratory glassware.

Efficient Air Removal

An optional vacuum pump can be used for fractioned pre vacuum air removal eliminating air pockets from all load types and maximizing efficient steam penetration throughout the entire load.

Active Drying with Post Vacuum

For benchtop autoclaves, an optional vacuum pump can be used for post vacuum drying, at the end of the sterilization cycle, ensuring improved drying of porous loads and hollow instruments such as pipette tips. The benchtop autoclave is equipped with a heating plate attached under the chamber that heats the chamber during the drying phase. The low pressure in the autoclave chamber, caused by the vacuum, reduces the boiling temperature forcing moisture to evaporate rapidly. The vapour is then removed from the chamber by vacuum resulting in a dry load.

For Applications that Need High Performance

Tuttnauer's high performance laboratory autoclaves are equipped with the following optional features: a built-in steam generator, a vacuum pump and a coiled pipe around the chamber. These autoclaves provide efficient heat-up and complete drying.

Fast and Efficient Heat-up

Immediate Steam and Efficient Air Removal

During the heat-up phase air is efficiently removed from the chamber by a strong vacuum pump. Steam, that is immediately available from the built-in steam generator, is then injected into the autoclave for immediate chamber heating.

Complete Drying

Chamber Heating and Post Vacuum

Highly efficient drying is achieved by uniformly heating the chamber wall of the benchtop or vertical autoclave. This is achieved by heating the chamber from steam passed through a coiled pipe around the chamber. The post vacuum stage reduces the boiling point which speeds up drying. This results in faster and complete drying, and guarantees that even the most difficult loads such as textiles, porous loads, hollow instruments and tips, will dry.
