About this model
The indestructible CertoClav Classic, the further development of the stainless steel CertoClav EL, is extremely low-maintenance. A precision thermometer, a control valve and a precision manometer with drag indicator ensure exact processes and perfect results for all applications. The model is available in two versions, each with two temperature levels.
Full description from the catalogueShow less
You can choose between the 125/140 °C and 115/121 °C models. The respective temperature level is set via the control valve in the lid. The valves cannot be interchanged as the thermostat of the appliance is matched and adjusted to the respective valve! The 2nd generation of our laboratory autoclaves comes with a new design, more functions and a newly developed touchscreen control. The steam sterilisers impress with their solid construction and are extremely low-maintenance. Venting is carried out using a flow process or fractional venting. The sterilisation chamber is made of corrosion-resistant, electropolished stainless steel (316L). This makes it extremely robust. A heater is screwed to the bottom of the chamber, but the heating elements are not directly in the water and therefore cannot calcify. This extends the service life of the autoclaves. Our laboratory autoclaves are ready to use in just a few simple steps. The sterilisation chamber can be opened and closed safely and easily with a single movement; simply turn and remove the lid. They are transportable and location-independent. Only a power supply is required. The water supply is a mixture of tap water and demineralised water. Our autoclaves are protected by a multiple safety system. It consists of a pressure relief valve, a pressure valve, a safety lid lock to prevent opening under pressure and a BI metal fuse to prevent the appliance from overheating. Important features: robust construction Temperature settings 125/140 °C Thermostat control simple operation Integrated timer venting in flow process Precision manometer with drag indicator Heating integrated in the base Ideal for the sterilisation of unwrapped solids without hollow bodies, liquids, bottles, instruments and plastics. Also suitable for culture media processing and waste sterilisation.

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).
