Innovation in glass reaction systems

Designed to enable quick, easy and safe removal, the new valve eliminates the cleaning and removal problems associated with traditional stopcock designs

Radleys has introduced an innovative new V4 zero dead space stopcock for its range of jacketed glass reaction systems.

Designed to enable quick, easy and safe removal, the new valve eliminates the cleaning and removal problems associated with traditional stopcock designs.

Its zero dead volume format ensures that all the vessel contents are stirred and heated/cooled evenly.

The valve, available in 15 or 25mm nominal bore to suit different vessel sizes, is manually operated to open for sampling or removal of contents.

Constructed from borosilicate glass, PTFE and FEP encapsulated silicone, the new V4 valve offers high chemical resistance and operates over the temperature range -50 to +200C.

For more demanding applications optional high performance O-ring materials are available.
