Performance you can trust – with the modularity to meet your needs

Our concept – a modular device concept

Choosing a basic device
Floor or tabletop model?
Floor models make the best use out of the chamber volume by using baskets with the height of respective bottles.
Tabletop models can be easily loaded and unloaded, can be charged without baskets and require a massive table or an undercarriage.

Chamber volume of 25 to 200 litres
Which chamber volume is required?
What footprint is available?

The models are manufactured in different sizes. Our in-house production allows us to offer otherwise identically constructed devices with an extended chamber at low costs.

Applications
Sterilisers are part of the standard equipment of every microbiological laboratory.

Liquids and culture media are usually autoclaved at 121°C and 134°C. This complies with the requirements of most application fields. The basic devices of our models are already equipped for these typical laboratory tasks.

If monitoring of production processes is needed, a special module makes the sterilisation data traceable by printing it directly or by transferring it to external software.

Classifications for biological and genetically modified agents or infectious germs in the clinical field are defined according to their risk (also see “Guideline for sterilisation”).

Please clarify the classification of your laboratory and the requirements if needed with the relevant regulatory body.

Services after purchase
Transportation, installation, commissioning, training and installation testing according to the regulation for industrial safety by an authorised person, on demand operational qualification and validation of defined processes.

VARIOKLAV steam sterilisers comply with the European Pressure Equipment Directive and are equipped and certified for stationary as well as mobile operation.

Customer-oriented processes
How often and what, at what quality requirements is sterilised?
Apart from few exceptions all applications typical for a laboratory are covered by the two fast cooling modules and the two vacuum processes pre-vacuum for deareation and post-vacuum for drying.

Using these, sterilisation processes of liquids in open and hermetically-closed vessels as well as solid and porous goods (expendable materials) are swiftly performed with high quality.

When potentially hazardous agents are involved, the respective requirements and regulations need to be fulfilled. In these cases the module exhaust air filtration with condensate sterilisation in combination with the documentation module (for traceability of the sterilising process) ensures a validated and safe operation.

Extensions
4 additional measures need to be provided especially for hazardous materials that should be sterilised (on request).

All models are available with an extended chamber and most modules are retrofittable if the sterilisation chamber is already equipped with a double jacket for cooling and heating.
For special sterilisation tasks more programmes are obtainable, e.g. for Durham tubes. Processes without prior venting are especially suited for steam/air mixtures. Sterilising temperatures above 134°C are also possible.

It is recommended to stir culture media flasks with a capacity of more than 10 litres, during the entire sterilisation. The continuous circulation of the liquid through a magnetic stirrer prevents the occurrence of a temperature gradient – hot at the top and cold at the bottom – in the media and minimises the risk of high thermal stress in the upper layers.

Accessories
An abundant supply of round, square, open and closed sterilising baskets, lifting hoists and for media supplying completes our product portfolio.
