Memmert Steriliser S SF75plus

Memmert Steriliser SF75plus

Advanced Hot Air Sterilisation for Demanding Laboratory Environments

The Memmert SF75plus is a high-performance hot air steriliser, designed for reliable, even sterilisation of laboratory instruments and equipment. Certified as a medical device (CE 0197), it meets all relevant standards and offers maximum process reliability thanks to intelligent features like TwinDISPLAY and SetpointWAIT. This unit is ideal for facilities requiring high-precision sterilisation with forced air circulation.

Features

• TwinDISPLAY digital PID controller with two TFT colour displays for advanced control

• SetpointWAIT function ensures sterilisation starts only once all target temperatures are reached

• HeatBALANCE for adjusting heat distribution between top and bottom heating elements

• Two Pt100 sensors for redundant temperature monitoring and error backup

• Quiet, adjustable fan for consistent air circulation

• Programmable via AtmoCONTROL software (USB/Ethernet)
