About this model
For more than 60 years, the CertoClav EL has been our tried and tested economic autoclave end-to-end solution with valve control. A precision thermometer, a control valve, and a precision manometer with drag indicator provide precise processes and accurate results for all applications. This model is 125/140°C , with two temperature levels.
Full description from the catalogueShow less
These temperature settings are controlled via the control valve on the lid. These valves are not interchangeable, because the thermostat of the device is harmonized with and calibrated to the respective valve! Ideal for the sterilization of unpackaged solids without hollow bodies, liquids, bottles, instruments, synthetic materials, food preservation, culture media preparation, and waste Key features robust construction temperature levels 125/140 °C thermostat controlled simple operation high heating power electrical heater integrated in the base venting by flow procedureprecision thermometer precision manometer with drag pointer Also available as a SET with a wire basket, made of stainless steel, for convenient handling of autoclaving goods.
Intended loads
Laboratory waste
Contaminated cultures, plates and disposables, reliably inactivated.
Culture media
Agar and broth sterilised without boiling over or scorching.

What goes into the chamber.
Examples from the round wire basket that goes into this chamber.

Culture media in bottles

Plastics and rubber

Organic materials

Laboratory waste in disposal bags
Waste in bags needs a long hold. One hour is the recommendation here. A vacuum autoclave does the same load in four minutes.

Contaminated cultures and disposables
Sealed bottles
- Crimped or tightly closed glass bottles up to 40 ml: every autoclave.
- Above 40 ml, support pressure is required.
- Plastic bottles, closed or crimped, always need support pressure, whatever the volume.
- Only the VacPro 45 L offers support pressure (ordering option 8500613).
