DEVICE AND METHOD FOR TRANSFERRING FLUIDS FOR ANALYSIS

摘要

A device and method for transferring fluids between closed vials is provided. In one embodiment, a reagent transfer vial (42) is provided. In a further embodiment, the reagent transfer vial is used in conjunction with a transfer device (10) which includes a cylinder having a pair of opposing open tubes or tubular portions into which a sample vial (12) and the reagent transfer vial (42) can be inserted to transfer fluid therebetween. The tubes are separated by a wall through which extends a fluid transfer needle (40) and a vent needle (24) which first is inserted into a sample vial to vent the sample vial into a vent chamber (36) or reservoir formed in the transfer device before the transfer needle is inserted into the sample vial.
