Materials

  • Chamber: Stainless Steel (304/316)
  • Seals: High-grade silicone
  • Exterior: Powder-coated or stainless steel
  • Heating Element: Nichrome or ceramic insulated

Product Form & Features

  • Electric-powered steam sterilizers
  • Available in semi-automatic and fully automatic models
  • Digital programmable control panel
  • Optional IoT-enabled monitoring features

Usage & Applications

  • Human Medical: Sterilization of surgical instruments, syringes, and dressings.
  • Hospital & Lab Use: Waste decontamination and microbiology applications.
  • Veterinary: Sterilizing surgical tools, bedding, and field clinic equipment.

Sterilization Process

  • Standard cycle: 121°C at 15 psi for 15–30 minutes.
  • Advanced cycle: 134°C vacuum-assisted sterilization (Class B).
  • Steam displacement via gravity or vacuum-assisted flow.
  • Validation with chemical or spore indicators.

Advantages

  • Eliminates all microorganisms including spores and fungi.
  • Eco-friendly alternative to chemical sterilization.
  • Automatic monitoring ensures safety and compliance.
  • Enables efficient reuse of instruments and tools.

Disadvantages

  • Unsuitable for heat-sensitive materials.
  • Overloading reduces sterilization effectiveness.
  • Higher initial investment for Class B autoclaves.
  • Requires reliable power and distilled water.

Precautions

  • Avoid sealed containers — explosion risk.
  • Do not use aluminum foil wraps.
  • Do not overload; maintain proper spacing for steam circulation.
  • Inspect gaskets and safety valves regularly.
  • Open only after full pressure release; use heat-resistant gloves.

Handling & Maintenance

  • Daily: Clean chamber and drain water.
  • Weekly: Check for residue and scaling.
  • Monthly: Inspect gasket and test indicators.
  • Annually: Perform professional calibration and validation.

FAQs

Q1: Can plastics like syringes be autoclaved?
A: Only autoclave-safe plastics such as polypropylene can be used; others may deform.

Q2: Is distilled water required for operation?
A: Yes, distilled or deionized water prevents scaling and extends equipment life.

Q3: Can liquids be sterilized?
A: Yes, but only in vented containers with slow cooling cycles to prevent bursting.

Q4: What is the difference between Class N and Class B autoclaves?
A: Class B autoclaves include vacuum-assisted cycles for wrapped and hollow instruments, while Class N is for unwrapped items only.
