Request Information
  • The ability to create a vacuum in the sample chamber by a connection to a vacuum source ensures optimal retrieval of a representative, contamination free sample.
  • The S32 type sampler in overflow vacuum configuration provides a system purge to an overflow chamber and needle purge in addition to a fixed sample.
  • The unique design offers a user-friendly operation by multiple valves, allowing for sampling reactors and vessels at atmospheric or vacuum conditions.
