DEVICE FOR SIMULTANEOUS PROCESSING OF DISCRETE QUANTITIES OF FLOWABLE MATERIAL

摘要

A device, in the form of a multi-well plate, for simultaneous processing of discrete quantities of flowable material for the purpose of, for example, purification, concentration or extraction of target substances comprises an injection-moulded body (10) with a plurality of receptacles (12) each having an entry end opening (12a) for introduction of an individual charge of the flowable material and an exit opening (12b) for outflow of at least part of the material. A single membrane (16), for example an ion exchange or a filtration membrane, is fixed to the body (10) by bonding to close the exit openings (12b) of the receptacles and form an external face of the device. The membrane (16) is formed with individual effective zones (16a) each closing the exit opening (12b) of a respective one of the receptacles and each separated in terms of flow from the outer zones. The zones (16a) can be defined by cuts (17) extending entirely through the membrane.
