The field decides the load. The load decides the cycle.

The classic case, and the one with the widest span: culture media go in sterile, cultures come out as waste. One laboratory needs both processes on the same day.

• Media preparation with a probe in the vessel, so the cycle follows the medium and not the chamber
• Disposal of plates, tubes and contaminated disposables
• Fractionated pre-vacuum for bagged loads that would otherwise trap air

Sterility testing and challenge testing need media that are reproducible from batch to batch, and a record of every cycle that produced them.

• Reproducible media batches with documented holding time
• Batch records written automatically, to CertoCloud or a private cloud
• Programmable profiles for pasteurisation ranges below 100 °C

Ageing and stress tests do not care about sterility. They care about a temperature that stays where it was set, for as long as it was set.

• Programmable profiles from 20 °C upwards
• Long cycles, in the MultiControl series up to seven days
• Recorded temperature curve for every run

A teaching laboratory runs many short cycles operated by people who are still learning. The machine has to survive that, and it has to be hard to get wrong.

• Simple operation with stored programmes
• Robust aluminium or stainless steel chambers
• Service and spare parts from the same people who built the device

Wrapped goods and hollow bodies are the hardest load. Steam has to reach every surface, and what comes out has to be dry, or the wrapping is worthless.

• Vacuum-assisted penetration on the VacPro series
• Controlled drying phase after the holding time
• Qualification of installation and operation available as a service item
