The Thermo Scientific Midi 40 CO2 Incubator offers 40 litre interior volume in a compact benchtop design. With radiant wall heating, a thermal conductivity sensor and a removable water reservoir, you culture small volumes of cells under stable, reliable conditions.
The Thermo Scientific Midi 40 CO2 Incubator is designed for cell culture scientists who need a compact workspace. With a capacity of 39.6 litres, this benchtop incubator delivers the performance of a full-sized incubator in a small footprint. Therefore, you choose the Midi 40 for personal use, small workloads or laboratories with limited space.
The Midi 40 replaces shared use with a personal incubator. As a result, you reduce contamination from unnecessary handling and repeated door openings. Moreover, you easily dedicate the cabinet to a specific cell line or study when separating samples is essential. The cabinet holds up to 35 T75 culture flasks.
The radiant wall heating system distributes heat evenly through natural air convection. Therefore, the cabinet reaches an accurate, uniform temperature that protects your samples. The thermal conductivity sensor sits directly in the chamber and ensures responsive CO2 control and a long service life.
The seamless, deep-drawn stainless steel interior with coved corners is easy to clean. The IntrLogic II microprocessor displays temperature and CO2 on a bright display. A keyed setpoint switch prevents unauthorized changes. Additionally, the tempered inner glass door prevents condensation and protects your samples.
The Midi 40 is ideal for medical diagnostics and small-scale research. Also explore our larger CO2 incubators or ask for advice via our Thermo Scientific page.

The Midi 40 is intended for researchers who need a compact, personal workspace. Therefore, this benchtop incubator suits small workloads, personal use and laboratories with limited space.
The Midi 40 holds up to 35 T75 culture flasks on four removable shelves. As a result, you use the 40 litre interior volume efficiently for smaller culture volumes.
The Midi 40 uses a thermal conductivity sensor located directly in the chamber. Therefore, the cabinet controls CO2 responsively and with a long service life, at a control accuracy of plus/minus 0.1%.
The Midi 40 generates relative humidity up to 95% at 37 °C via a removable water reservoir. As a result, humidity recovers quickly and your cell cultures remain under optimal conditions.
Yes, the cabinet is reinforced to allow stacking. Additionally, the compact cabinet fits well on a benchtop, so you add culturing capacity in a crowded laboratory.
