Selection Valves are biocompatible & inert and deliver a low swept volume. Their unique design allows for minimal dispersion. Selection valves come conveniently in both manual standard and bulkhead-mount versions. They have a pressure rating of up to 1,000 psi (69 bar). IDEX offers two versions – one for 1/16″ OD tubing and another for 1/8″ OD tubing available in two configurations: standard manual and bulkhead-mountable manual. A valve mounting bracket is available to secure the bulkhead-mount versions to a lab bench or counter surface.
