Vertical Autoclave - Class N Steam Sterilizer - 30L 50L 75L - 134°C Microcomputer Control

The Master Science Class N Vertical Autoclave is a top-loading steam sterilizer for laboratories, hospitals and production facilities that need dependable sterilization of media, glassware, instruments and waste. It is offered in 30 L, 50 L and 75 L chamber sizes, each available in semi-automatic or fully automatic configuration.

The chamber is made of food-grade 304 stainless steel and the outer shell combines stainless steel with impact-resistant, heat-resistant thermoplastic. A microcomputer runs the full cycle and shows its progress on an LCD window, so the Master Science Class N Vertical Autoclave stops and alarms on its own when sterilization is finished.

Key Benefits

• Hands-off cycles: Microcomputer control runs heating, sterilization and exhaust automatically and signals when the load is ready.
• Shorter turnaround: An air-cooled rapid cooling device brings the chamber temperature down quickly so the lid can be opened sooner.
• Safe operation: A combined electrical and mechanical interlock keeps the lid locked while the chamber is under pressure.
• Right size for the load: Three chamber volumes let you match the autoclave to daily throughput.

For small loads of wrapped instruments that need vacuum drying, see our Class B benchtop autoclave.

Problems the Master Science Class N Vertical Autoclave Solves

Manual sterilizers cost staff time and carry safety risks. The Master Science Class N Vertical Autoclave addresses the usual issues:

• Constant supervision: Automatic cycle control and an end-of-cycle alarm free staff from watching the gauge.
• Long waits before unloading: Rapid air cooling shortens the time until the lid can be opened.
• Risk of opening under pressure: The lid interlock prevents opening while pressure remains in the chamber.
• Boiled-dry heaters: Anti-dry protection and fault detection protect the heater and the load.
• No cycle records: An optional printer documents temperature and time for each run.
