In a Memmert constant climate chamber HPP750life mice can be kept in a specific pathogen free (SPF) state. Ideally the climate chamber is located in a clean room. In order to guarantee the recommended humidity of between 45 and 65 % rh for the humane keeping of mice even at low temperatures, Memmert integrated a compressed air drying unit. For simulation of the day and night rhythm, the LED illumination can be programmed using the AtmoCONTROL software. Temperature range up to +70 ? model size 750l Digitally controlled active humidification and dehumidification 10% up to 90% Efficient dehumidification of the chamber by means of compressed air for safe and stable humidity values in compliance with GV Solas guidelines Air exchange rate (max. 38 times per hour) can be controlled by adjusting the speed of the exhaust air motor Programme controlled LED light strips (on 2 levels), adjustable in steps of 1 % (5,500 K cold white or 2,700 K warm white); adjustment angle 45° Developed in cooperation with the Institute for Molecular Nutritional Medicine of the Technical University of Munich headed by Prof. Dr. Klingenspor
