BBD 6220 provides stable growth conditions and a high degree of security and protection against contamination. Typical applications are for IVF or pathogenic work. Range: ambient + 5 °C to 50 °C, humidity greater than 95 % R.H. and CO₂ concentrations between 0 and 20 % Vol are reliably achieved via a microprocessor controlled measuring and control system. An automatic disinfection routine at 180 °C, which safely eliminates bacteria, fungi and spores, decontaminates the entire interior space including the sensors and fittings. The humidity water reservoir is located outside the chamber. The water is sterilised before it is used for humidification. The stainless steel chamber is crevice-free with rounded corners for easy cleaning. Includes "Heraeus CO₂ Autozero System" overtemperature protection with separate probe and RS232 interface.
