System and method of aspirating and dispensing reagent

摘要

Aspirating and dispensing of reagents is accomplished using a probe (119) having an outlet (144) connected via tubing (142) to a syringue pump. The probe (119) has an o-ring (134) for sealing against a vial insert (150) coupled to a dip tube (156) in the reagent vial during aspiration. The probe (119) is then moved to a dispense and washing station that seals against the o-ring (134), and the reagent is dispensed and the probe washed.
