Abstract
A solvent debubbling/priming device for use in high pressure liquid chromatographic applications includes a valve adapted for releasable and sealed attachment to a bubble collecting/solvent reservoir. The valving portion of the device comprises a valve body with bores formed therein for controlled access and communication between the bubble collecting/solvent reservoir and the exterior of the valve, or atmosphere. The solvent debubbling/priming means includes a length of flexible tubing which has a flattened portion at its distal end and with the tubing being in communication with the bubble collecting/solvent reservoir. The flexible tubing along with its flattened portion provides a flow control and check valve which is chemically inert and free of potentially contaminating lubricants for effective utilization.
