When it comes to successful in vitro fertilisation, precision and reliability of CO2 incubators are of utmost importance. Even minimal discrepancies in CO2 and O2 concentration, temperature or humidity can influence the development of the cell culture. To keep the recovery times of the INCO108med incubator to a minimum, Memmert has developed an IVF module with separate slide-in units for the Petri dishes. The Memmert CO2 incubator INCOmed is classified as a class IIa medical device and complies with the basic safety requirements as stipulated in the European Medical Device Directive (93/42/EEC).
IVF module with separate slide-in units for the cell cultures
In conventional CO2 incubators and in special IVF incubators, vaporisation and condensation are a major problem. The Memmert IVF module is used in a Memmert CO2 incubator INC108med. This ensures that the CO2 content, O2 content and humidity in the interior can be controlled with absolute precision. The active humidification and dehumidification, in particular, keeps vaporisation to a minimum, meaning additional cultivation under oil is not required.
8 slide-in units offer space for a total of 24 4-well dishes, 24 large Petri dishes measuring 60 mm in diameter or 48 Petri dishes measuring 35 mm in diameter. The Petri dishes are placed on indentations for better heat distribution and cannot slip out of position when the slide-in units are pulled out. The low air exchange with the outside ensures fast recovery times for the CO2 content and humidity because as long as one slide-in unit is open, no other unit can be pulled out. Further safety features of the IVF module: easy-to-clean steel, all slide-in units can be labelled individually and are equipped with a pull-out lock, the chamber including all installations can be sterilised in a 4-hour programme and the low-vibration roller feed-throughs of the slide-in units work without lubricant.
Uniform temperature distribution: Interior heated on all 6 sides:
For the INCOmed, the tried and tested Memmert heating concept was once again perfected: heating the interior on all six sides, along with the electronic humidity limit control, is decisive in preventing condensation from forming in the inner chamber, while offering maximum protection to the cell cultures. An aluminium thermal conductive layer supports optimum temperature distribution, and serves as a heat accumulator in case of a temporary power failure. The turbulence-free chamber ventilation ensures a constant and uniform atmosphere.
