Needle Valve

The Hamilton 16 gauge 9.5 Inch needle valve is suitable for use with syringe, which is used in laboratory and research use.

Laboratory Needle Valves are deck mounted turret base. They are straight pattern forged brass. They have a floating stainless steel needle and replaceable stainless steel seat. The handle is a four-arm handle with a color coded index button/cap.

Manual vacuum regulation can also be a very cost-effective solution. Air is drawn in through a fine regulation valve and the resulting vacuum is set. A manometer displays the pressure. The recommended Woulff bottle acts as a buffer vessel and condensate trap.
