Vertical Autoclave - Class N Steam Sterilizer - 35-100 L Chamber - 116-134°C

The Master Science Vertical Autoclave is a Class N steam sterilizer for laboratory media, glassware, instruments and waste. A hand-wheel quick-opening lid, self-expanding door seal and microcomputer control make daily cycles simple, while digital display and touch buttons let users set any sterilization temperature and time.

Four chamber sizes from 35 L to 100 L are available. A three-stage pressure pulsing program removes air more completely for higher steam saturation and better sterilization results.

Common Laboratory Problems and How This Autoclave Helps

How the Master Science Vertical Autoclave addresses typical sterilization issues:

• Air pockets reducing sterility: triple pulsing improves steam penetration.
• Boiling dry: low-water protection stops heating.
• Unsafe lid opening: the interlock prevents opening under pressure.
• Staff waiting for cycle end: auto exhaust and buzzer signal completion.
• Different volume needs: four chamber sizes are available.
