  • The ability to purge the sample point ensures optimal retrieval of a representative, contamination free sample.
  • The S23 type sampler with cooling/heating jacket provides a system purge and a fixed sample volume at the required temperature.
  • A separate cooler/heater is therefore not necessary.
  • 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.
