Options

Valve
The standard 3570 Series does not come with an outlet valve.  The diaphragm valve is the 4370 Series and the needle valve is the 1003B.

No Lube
A small amount of polychlorotrifluoroethylene is added to the threads to facilitate assembly. For ECD, MS or AED applications where method detection limits are sub-ppm, it is recommended to use a No Lube (-NL) model.

Cross Purge
• Eliminates the escape of hazardous gases when changing cylinders
• Reduces danger of contamination from atmospheric moisture and oxygen
• Minimizes the amount of gas lost during cylinder changes
• All stainless steel construction
• 4360 Series Quarter-Turn Diaphragm Valves used throughout
