Portable Pressure Steam Sterilizers – Vertical Laboratory Sterilization Systems Portable pressure steam sterilizers are vertical, top-loading steam sterilization systems used to sterilize laboratory instruments, glassware, culture media, textiles, and biohazard waste using saturated steam at 105–134°C under controlled pressure. They are used in laboratory, clinical, veterinary, and field environments where compact sterilization capacity is required.

What is a Portable Pressure Steam Sterilizer?

A portable pressure steam sterilizer is a vertical autoclave system that sterilizes laboratory materials using high-temperature saturated steam under controlled pressure.

It is used for sterilization in environments requiring compact size and flexible installation.

What does a portable pressure steam sterilizer do? It sterilizes laboratory and clinical materials by exposing them to saturated steam at controlled temperature and pressure for a defined exposure time.

It is used for:

• Laboratory instruments

• Glassware (flasks, beakers, cylinders)

• Culture media and reagents

• Wrapped instruments

• Biohazard waste

• Laboratory textiles

How does a portable pressure steam sterilizer work? It works by generating saturated steam inside a sealed vertical chamber and maintaining controlled temperature and pressure to achieve microbial inactivation.

Process flow:

• Vertical loading of materials

• Chamber sealing with locking system

• Steam generation via electric heating

• Sterilization at 105–134°C

• Controlled exposure phase

• Gradual pressure release
