The Table Top Autoclave Class N Series is a compact 18-liter sterilization system designed for laboratory glassware, instruments, and culture media sterilization. Operating at standard autoclave temperatures of 121°C and 134°C with 0.22 MPa working pressure, this tabletop unit provides reliable steam sterilization in a space-efficient footprint suitable for bench installation.
The autoclave features a SUS304 stainless steel chamber (φ250×370mm) with LED display for temperature monitoring and includes one rack with two trays for flexible load configuration. Manual door operation and straightforward controls make this system appropriate for routine sterilization workflows in research laboratories, small clinical facilities, and educational institutions requiring consistent decontamination of laboratory materials.
How It Works
Steam sterilization operates through moist heat destruction of microorganisms via protein coagulation and enzyme denaturation. Saturated steam at 121°C or 134°C penetrates materials and maintains lethal temperatures for prescribed exposure periods, achieving sterility assurance levels appropriate for laboratory use.
The autoclave chamber reaches working pressure of 0.22 MPa, generating saturated steam conditions that displace air and ensure uniform heat distribution throughout the load. Temperature precision of ±0.1°C maintains consistent sterilization parameters across cycles. The SUS304 stainless steel chamber resists corrosion and provides even heat transfer for reliable temperature control during the sterilization process.

Practical Tips
Verify temperature accuracy monthly using calibrated thermocouples placed at multiple chamber locations.
Why: Ensures uniform temperature distribution and validates sterilization effectiveness across the chamber.
Clean chamber weekly with mild detergent and inspect door seal for cracks or deposits.
Why: Prevents contamination buildup and maintains proper seal integrity for pressure retention.
Allow adequate spacing between items and avoid overloading to ensure steam circulation.
Why: Proper steam penetration is essential for achieving sterility throughout the load.
Always wear protective gloves when handling hot items after sterilization cycles.
Why: Chamber and contents remain at lethal temperatures immediately following sterilization.
Record cycle parameters including temperature, time, and load details for each sterilization run.
Why: Documentation supports process validation and troubleshooting of sterilization failures.
If temperature fluctuations occur, check water level and verify proper door seal closure.
Why: Insufficient water or air leaks compromise steam generation and temperature stability.

Compliance
What sterilization cycles are recommended for different laboratory materials?
Use 121°C for culture media and heat-sensitive materials, 134°C for instruments and glassware. Cycle times depend on load density and material type - consult sterilization protocols for specific exposure requirements.
How do I verify sterilization effectiveness for critical applications?
Use biological indicators (spore strips) and chemical indicators appropriate for steam sterilization. Monitor temperature precision using the LED display and maintain sterilization logs for validation.
What maintenance schedule is required for reliable operation?
Perform daily water level checks, weekly chamber cleaning, and monthly door seal inspection. Replace distilled water regularly and descale chamber according to water quality and usage frequency.
Can this autoclave handle wrapped instruments and porous materials?
As a Class N autoclave, it is designed for simple loads like solid instruments and glassware. For wrapped items or porous materials, consult product datasheet for load-specific guidance.
What are the space and utility requirements for installation?
Requires stable bench space accommodating 35×50×40cm dimensions plus clearance for door operation. Needs 1.5kW electrical supply and access to drainage for condensate removal.
How does chamber size affect loading capacity for typical lab items?
The φ250×370mm chamber accommodates standard Erlenmeyer flasks, media bottles, and instrument sets. Use provided rack and trays to optimize spacing for steam circulation around loaded items.
