Memmert SF75 Hot-Air Steriliser, 74 L, Class IIb medical device

Product information "Memmert SF75 Hot-Air Steriliser, 74 L, Class IIb medical device"

The Memmert SF75 hot-air steriliser is a Class IIb medical device (in accordance with MDD 93/42/EEC, transitional provisions until 31 December 2028 pursuant to (EU) 2023/607) designed for the sterilisation of medical materials using dry heat at atmospheric pressure. With an internal chamber volume of 74 litres and a temperature setting range of +20 to +250 °C, the unit is suitable for everyday use in medical practices and laboratories with a regular, moderate throughput.

Precise temperature control with SetpointWAIT

A 1 Pt100 DIN Class A sensor in a 4-wire configuration measures the temperature with an accuracy of ±0.1 °C up to 99.9 °C and ±0.5 °C from 100 °C onwards. The SetpointWAIT function only starts the sterilisation time once the setpoint temperature has actually been reached – ensuring validatable, reproducible cycles. The air turbine is electronically controlled, adjustable in 10 % increments and low-noise; in addition, electronically controlled fresh air and exhaust air dampers ensure controlled air exchange.

Robust construction and safety

The interior is made of stainless steel with deep-drawn ribbing and is heated on all four sides; the fully insulated stainless steel door locks via a 2-point compression lock. For safety, the unit monitors the temperature electronically and additionally via a mechanical temperature limiter (DIN 12880 Class 1), which triggers at around 20 °C above the maximum temperature. An integrated self-diagnostic system automatically detects faults.

Operation, interfaces and documentation

The SF75 is controlled via the ControlCOCKPIT SingleDISPLAY: an adaptive digital PID microprocessor controller with a high-resolution TFT colour graphic display and a digital timer (1 min to 99 days). Log data can be read out, managed and organised via the Ethernet interface (a time-limited trial version is available for download); a USB stick containing the AtmoCONTROL software is available as an accessory on request. The programme sequence remains stored even after a power cut – this significantly simplifies documentation for quality management.

Typical areas of application

As a Class IIb medical device, the SF75 is designed for the sterilisation of medical materials using dry heat at atmospheric pressure – typical applications include:

  • Sterilisation of surgical instruments in clinics and hospitals
  • Reprocessing of instruments in doctors’ and dentists’ surgeries
  • Sterilisation of laboratory glassware and accessories in microbiological and pharmaceutical laboratories
  • Practice and hospital hygiene with documented, validatable processes
