Thermo Scientific
CO2 Incubator Midi 40

The Thermo Scientific Midi 40 CO2 incubator is designed specifically for cell culture scientists who require a compact culturing workspace to handle small workloads, perform personal use applications or simply address limited space environments. It delivers the performance and capabilities of full-sized incubators in a space-saving footprint, ideal for those who wish to avoid shared-use environments that can present potential contamination risk through unnecessary sample handling and repeated door openings.
  • Advanced IntrLogic II microprocessor: bright digital display and intuitive touchpad for simplified entry of temperature, CO2 and alarm data, with keyed setpoint switch to prevent unauthorised changes to operating parameters.
  • St. steel culture chamber: seamless, non-corrosive and exceptionally easy to clean; Midi 40 is provided with 4 removable shelves.
  • Highly efficient direct heating design: provides even heat distribution to all sides of the chamber, for accurate control and uniformity.
  • Precise and reliable CO2 control: featuring accurate thermal conductivity sensor located directly in the chamber, ensuring responsive control and long service life.
  • Removable water reservoir generates relative humidity values up to 95 % with rapid recovery rates that promote optimal cell growth.
  • Tempered inner glass door provides sample security while preventing unwanted condensation.
  • Convenient data communication: RS485 signal output is standard, in addition to audible and visual alarm functions to ensure proper operations.
