Vertical Autoclave ADVA-520

1. How often should a vertical autoclave be serviced?

Routine maintenance should be performed every 3 to 6 months depending on usage frequency. This includes checking the gasket, valves, sensors, and heating elements. Annual calibration and performance validation are recommended to ensure proper functioning. Regular maintenance prolongs the lifespan and maintains sterilization efficacy. Always follow the manufacturer’s service guidelines.

2. What is a vertical autoclave and how does it differ from a horizontal autoclave?

A vertical autoclave is a cylindrical sterilization unit that loads from the top and is commonly used in laboratories and smaller medical facilities. It uses steam under pressure to sterilize instruments, media, and glassware. Unlike horizontal autoclaves, which are typically larger and load from the front, vertical autoclaves are more compact and ideal for space-constrained environments. Horizontal models are better for higher throughput or bulkier loads. The main difference lies in size, loading orientation, and volume capacity.

3. What types of materials and instruments can be sterilized in a vertical autoclave?

Vertical Autoclave can sterilize a wide variety of items including surgical instruments, laboratory glassware, culture media, rubber materials, and some types of textiles. They are also suitable for sterilizing liquids like culture broth, provided proper containers and settings are used. However, items sensitive to heat or moisture, such as certain plastics or electronics, should not be autoclaved. It's essential to check material compatibility with high-pressure steam. Always follow the manufacturer's recommendations to avoid damaging the load.

4. What is the standard sterilization cycle time and temperature for a vertical autoclave?

The most commonly used cycle in a vertical autoclave is 121°C at 15 psi for about 15–30 minutes, depending on the load size and type. For more resistant materials or larger loads, 134°C may be used for shorter periods (around 4 minutes). Cycle time includes heating, holding (sterilization), and cooling phases. It’s important not to interrupt the cycle to ensure proper sterilization. Time and temperature must be verified using thermometers or biological indicators for critical applications.

5. How does a vertical autoclave work (basic working principle)?

A vertical autoclave works by generating high-pressure steam to destroy microorganisms on instruments and materials. The chamber is sealed, and water inside is heated to produce steam that fills the chamber. Pressure builds up, allowing the temperature to rise above 100°C, typically to 121–134°C. This high-pressure, high-temperature environment kills bacteria, viruses, fungi, and spores. Once the cycle completes, the pressure is released and items are cooled before removal.
