Product Description
Need to meter gases or liquids into a reaction a little at a time? This metering stopcock plug pairs a fine needle valve with a main on/off valve, so you can set a delivery rate and shut flow off completely without disturbing that setting.
This listing is for Kimble catalog number 821111-0002: Varibor Metering PTFE Stopcock Plug, Size 2. The plug is made entirely of PTFE, giving it broad chemical resistance and a self-lubricating seal that needs no grease. One end carries an inner standard taper joint and the opposite end a 90 degree hose connection, so it links ground glass apparatus to tubing from a gas or liquid supply. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.

- Main shutoff valve – Provides positive on/off control independent of the metering setting
