Multichannel system for the handling of immobilized biologically active substances

Multichannel system for the handling of solid immobilized, biologically active substances comprising:

• a horizontally arranged receiving plate loosely carrying a plurality of sample tubes open at both ends in a regular arrangement, said tubes containing solid immobilized biologically active substances;
• an adapter plate with a plurality of holders arranged above the receiving plate, said adapter plate coming into communication with the sample tubes by means of clamping engagement with said holders when the receiving plate and the adapter plate are moved together at a suitable distance with respect to each other;
• a plurality of channels, in the adapter plate connected to one holder and of narrow configuration when compared with the holder;
• a multichannel displacer pump, working alternatively as suction pump or pressure pump, said pump connected to said channels;
• a carrier plate having a plurality of recesses for holding samples to be analyzed each of said recesses positioned to correspond to one of the sample tubes, said carrier plate being exchangeable with said receiving plate;
• means for exchanging said receiving plate with said carrier plate.
