Patent ID: 7884301

Claim:
A device for sorting microparticles having a nozzle for supplying a sorting stream consisting of at least one sheath fluid and microparticles entrained therein, a sorting head including a vibration generator for dividing the sorting stream into a droplet stream and a deflection device for sorting the droplet stream into a throughflow and at least one side stream in dependence upon signals of an evaluation device, the evaluation device for analyzing the microparticle (s) contained in the droplet and for controlling the deflection device, a microbiological safety cabinet (msc) having a clean room for both product and personnel protection, the clean room having a top and a bottom and at least the nozzle, the vibration generator, and the deflection device are arranged in the clean room, in which parts of the evaluation device are arranged outside of the clean room, the clean room having an access opening for a user to access the clean room, a monitoring device is provided in a side wall of the msc through which the signals of the microparticles generated in the sorting stream are guided to the detectors of the evaluation device located outside of the msc, the clean room including a laminar air flow passing therethrough from at least near the top of the clean room to the bottom of the clean room, the clean room floor including suction openings for the laminar flow and the suction openings being in fluid communication with a suction channel, the clean room of the msc is divided into a first safety zone, in which the sorting head is accommodated, and a second safety zone, the device further comprising a tray, which is located underneath the sorting head.
