The CO2 incubators CB are equipped with a multifunctional microprocessor display controller with 4- channel technology for temperature, CO2, and O2 (unit with O2 control) levels and a digital display accurate to one-tenth of a degree resp. 0.1 vol.-%
The inner chamber, the pre-heating chamber and the inside of the doors are all made of stainless steel. The inner surfaces are smooth and therefore easy to clean. The inner chamber is deep-drawn from one piece, polished (suitable for pharmaceutical applications) and has no welds or inaccessible corners. The hinges and the seal of the inner glass door are glued from the outside to aid cleaning of the inner chamber. When operating the chamber at high temperatures (sterilization), the impact of the oxygen in the air may cause discoloration of the metallic surfaces (yellowish-brown or blue) by natural oxidation processes. These colorations are harmless and will in no way impair the function or quality of the unit.
The perforated shelves are also made of stainless steel. You can insert a maximum of 3 (CB 53), 6 (CB 150), resp. 8 (CB 210) shelves.
The housing is RAL 7035 powder-coated. All corners and edges are also completely coated.
The heating system of the CO2 incubator permits hot-air auto-sterilization at a set point of 187.5 °C / 369.5°F. Thus, a temperature of 180 °C / 356°F is maintained for at least 30 minutes on all internal surfaces, resulting in sterilization of the entire inner chamber. Therefore, this procedure meets all international guidelines regarding hot air sterilization, e.g. AAMI ST63, DIN 58947, European Pharmacopoeia.
Thanks to the standard safety device (class 3.1 according to DIN 12880), the set temperature is maintained in case of failure.
The gas enters the chamber via a fine filter (aseptic filter) with a high filtration efficiency that also filters the smallest particles.
A highly precise, drift-free CO2 infrared measuring system in combination with the permanent mixture of CO2 gas through a special proprietary gas mixing head developed by BINDER allows precise and constant CO2 concentrations for long periods. This creates optimum growth conditions for cultures. The CO2 measuring system can be removed from the inner chamber by hand and cleaned with suitable detergents if needed.
