The BioBlood BR 500 is a Gram BioLine refrigerator designed specifically for storing blood and blood components at +2…+6 °C. This version has a lockable right-hinged glass door, a white painted-steel exterior and a stainless-steel interior, with interior fittings configured to the user's needs.
Its MPC controller logs the history of temperature fluctuations, and when connected to a computer, selected periods can be documented as graphs or tables. Calibration settings survive a power failure, and the controller records how long the outage lasted and the temperature afterwards.
An extra sensor simulates the core temperature of the stored material, alarms are both visual and audible, and the setting buttons can be locked with a personal code. A volt-free contact passes alarms on. Smart defrost takes the cabinet temperature at the start of each cycle into account to keep defrosting short.
