Midi 40 CO2 incubator

Thermo Scientific Midi 40: The Compact, High-Performance CO2 Incubator

The Thermo Scientific Midi 40 is a small-capacity CO2 incubator specially designed for cell culture scientists who need a compact workspace to manage small workloads, personal applications or space-limited environments. With a capacity of 40 litres, the Midi 40 offers the performance and capabilities of large incubators in an economical and easy-to-use format.

The Midi 40 is equipped with an IntrLogic II microprocessor, which provides a bright digital display and intuitive touchpad for simplified entry of temperature, CO2 and alarm data. A key switch prevents unauthorised changes to operating parameters. The stainless steel culture chamber is non-corrosive and exceptionally easy to clean, with four removable shelves for maximum flexibility.

The high-performance direct heating design ensures even heat distribution on all sides of the chamber, guaranteeing precise control and temperature uniformity. The accurate thermal conductivity sensor, located directly in the chamber, ensures responsive control and long service life. The removable water tank generates relative humidity values of up to 95% with fast recovery rates that promote optimal cell growth.

The inner door made of tempered glass provides sample safety while preventing unwanted condensation. Data communication is provided by a standard RS-485 signal output, as well as audible and visual alarm functions to ensure correct operation. The Midi 40 also features a high-visibility fluorescent display for easy monitoring and a reinforced cabinet that allows stacking.

The Midi 40 is ideal for busy laboratories or for reducing operating costs with a low-throughput incubator capable of storing up to 35 T75 culture flasks.
