An improved apparatus and process for transferring fluids (48) in a multi-liquid reagent protocol. Serum/plasma for a therapeutic drug assay is first obtained and mixed with a fluorogenic drug reagent (48) within a first cuvette (38). After mixing, the reaction product is accessed through a small opening (50) by tipping the cuvette (38). Fluid transfer is effected through a capillary tube (12) having an accurately calibrated bore (14), the capillary tube (12) being held between its open distal and proximal ends (30, 32) by a gripping sleeve (24). The capillary tube holder (10) is then inserted into a second cuvette and suspends the capillary tube (12) over the liquid level (54) of a second reagent (56) in second cuvette (40). By vigorous up-and-down shaking of the second cuvette (40), the contents of the capillary tube (12) are discharged substantially uniformly throughout the liquid second reagent (56) in a short time period. Assay results are then obtained by inserting the second cuvette (40) and the reaction product of the second reagent within a fluorometer (60). |
