ABSTRACT:
A pump for discharging the contents of a sealed container, such as a test tube, is connected to a body member which includes an inlet path and a discharge path with a delivery tube in the discharge path. A predetermined clearance is provided between the exterior of the delivery tube and the interior of the discharge path, the clearance providing venting, or blow-by, such that temperature changes do not cause accidental discharge of the contents of the container, while still maintaining sufficient resistance to venting for permitting pressurizing the interior of the test tube with the pump for accurately controlling the discharge of the test tube contents. A second or supplemental vent is provided in the pump.
