  • Liquid sampler with internally coupled valves to take predefined quantities of liquids with low and elevated vapour pressure independent of process pressure and with zero dead volume.
  • The S23 type samplers are built from high quality stainless steel.
  • Installation by means of threaded connections, compression fittings or flanges.
  • Easy to use samplers with one handle operation providing optimum safety for the operator and the environment.
  • The S23 type samplers are standard equipped with a manual handle.
  • Spring return handles are optionally available.

Description N/A
  • The ability to purge the sample point ensures optimal retrieval of a representative, contamination free sample.
  • The S23 type sampler provides a system purge and needle purge in addition to a fixed sample volume.
  • The unique design offers a one handle operation by multiple valves, allowing for sampling independent of the process conditions.
  • These features provide sample accuracy and safety.
