MMM Group - MMM Stericell Hot Air Sterilizer

• Sterilisation of laboratory glassware and ceramic materials.
• Dry heat sterilisation of heat-stable instruments and tools.
• Thermal treatment of materials requiring precise temperature control.
• Depyrogenation of pharmaceutical containers and components.
• Drying and curing processes in research and industrial settings.

Typical capacity

Commonly ranges from 50 to 250 litres for laboratory models.

Power supply

Typically 230V, single-phase, 50Hz for UK operation, with higher capacity units potentially requiring 400V three-phase.

Temperature range

Units of this type commonly operate up to 250-300°C.

Temperature uniformity

Often specified as ±1-2°C within the chamber for effective sterilisation.

Heating method

Forced air circulation is standard for efficient heat distribution.

Control system

Typically features a microprocessor-based controller with programmable cycles.

Construction material

Inner chamber is commonly stainless steel for durability and ease of cleaning.

• What is the primary advantage of dry heat sterilisation over other methods?

  Dry heat sterilisation is effective for heat-stable materials that cannot tolerate moisture, such as powders, oils, and certain glassware, and does not leave residues.

• What maintenance is typically required for a hot air steriliser?

• Can this equipment be used for depyrogenation?

• What safety features are commonly found on these units?

• Is validation required for sterilisation processes using this equipment?

Dry heat sterilizers are valued for their ability to sterilize heat-stable materials without moisture, making them ideal for powders, oils and instruments. Buyers typically appreciate their reliability and lower running costs compared to steam alternatives. When purchasing used models, industry practice suggests checking chamber condition, temperature uniformity, and calibration history. These units are known for durability and straightforward maintenance, though proper documentation and functional testing before purchase remain essential for assured performance.
