Stopcocks

VALVES, IN-LINE, EXPOSED O-RING TIP, Hi-vac valve with bent arms to minimize hold up of fluids that would occur in conventional valves. Designed with a precision external thread for fine control.

CHEM-VAC&trade valve glass portion only. Valve has two sidearms sealed to the barrel at a 180&ordm angle to one another and bent to minimize hold up of fluids. Heavy duty rounded coarse thread and precision formed tapered seat.

CHEM-CAP, METERING, LOW HOLD UP, CHEM-VAC&trade CHEM-CAP&reg metering valve has an extended tip on the plug to allow semi-needle valve control of gases and liquids. Similar to CG-965 CHEM-VAC&trade valve but with the arms bent to minimize hold-up

CHEM-VAC&trade valve has single sidearm sealed at a 90&ordm angle to the barrel. This inexpensive configuration allows for the lower portion of the barrel to be sealed directly to the apparatus being constructed, making for more compact, stronger
