BM 323 is a revolutionary blood scale collection monitor and mixer which is suitable for use in either immobile or mobile states. By gently mixing and controlling the collection time, high-quality blood (platelets) can be provided. When the process starts, balancing will be performed automatically. It has the function of manually or automatically operating the pipe clamp. It is used with all available blood bags on the market. For total volume or net volume measurements, it may provide the best accuracy below 1%. It automatically monitors blood flow and has a buzzer alarm to collection time. It continuously displays the collected volume, flow rate and time when the collection occurs. The preset standard volume is easy to modify. In addition to the adjustable upper and lower flow and time alarm limits, it also repeatedly provides notifications for completed collection for every minute, including smooth mixing to ignore condensation.
