Hot Air Sterilizer SF55plus - Fair Condition

Brand: Memmert


The Memmert SF55plus hot air sterilizer is designed to ensure reliable sterilization in laboratory settings. With a usable volume of 53 liters and a temperature range from +20 °C to +250 °C, it meets the demands of medical and scientific environments. Its SetpointWAIT function ensures that the sterilization process only begins once the target temperature has been reached, guaranteeing consistent results. The unit features a digital PID controller, a TwinDISPLAY interface, and optimized air circulation enabled by an adjustable, low-noise fan. Designed for easy cleaning, it is ideal for daily use in laboratories.

Description

Memmert SF55plus: Reliable and Uniform Thermal Sterilization

The Memmert SF55plus hot air sterilizer is designed for professionals seeking precise, consistent, and regulation-compliant sterilization of instruments. With an internal volume of 53 liters, this compact model provides a high-performance solution for laboratories, hospitals, and research centers.

Thanks to SetpointWAIT technology, the sterilization process begins only when the set temperature has been reached throughout the chamber, especially when an external Pt100 sensor is used. This ensures full compliance with sterilization conditions, resulting in reproducible and reliable outcomes.

Temperature regulation is controlled by the ControlCOCKPIT TwinDISPLAY system, which combines a PID microprocessor with two high-resolution color TFT displays. Users can accurately adjust parameters such as temperature (in °C or °F), fan speed, air flap position, and program duration. The HeatBALANCE function also allows power balancing between the upper and lower heating elements.

The SF55plus features a forced air circulation system with a quiet turbine fan and preheated fresh air supply, ensuring uniform heat distribution and effective sterilization, even under maximum load conditions (up to 80 kg).

Safety is a core design principle, with triple overheating protection (mechanical limiter TB, electronic monitoring TWW/TWB, AutoSAFETY system), visual and audible alarms, integrated self-diagnostics, and program memory backup in case of power failure.

The chamber is made of electropolished stainless steel, with a double-locking door and reinforced insulation. The sterilizer is supplied with one shelf and can accommodate up to four levels. Maintenance is simplified thanks to smooth interior surfaces and a seamless design free of dead corners.

Connectivity is enabled via USB port or Ethernet interface, with the AtmoCONTROL software (included on USB stick) for easy cycle programming and monitoring.
