Designed for sampling powders, flakes, and pellets, the ISOLOK SAH  sampler ensures that your samples are representative of your entire process
The Sentry® ISOLOK® SAH automatic point sampler is an extended stroke sampler for collecting flowable free-falling materials within chutes or slides. A three-inch plunger stroke collects samples inside heavy-body or double-wall vessels such as mixers, dryers, and reactors.
An air cylinder extends a single plunger into the process material, then immediately withdraws, carrying a fixed amount of sample trapped in an annular ring between plunger seals. Process or flow ports are always closed, preventing leaks or product loss. There are no tubes or passages to become clogged. The gravity-discharged sample is transferred directly to a closed container.

  • The SAK powder sampler is designed to capture a 16 or 18cc sample.
  • The sampler is available in versatile seal options to meet your process needs.
  • Handles powder, flakes, and pellets up tp 5/8 inch (16mm) without shearing or degrading sample material.
  • The Sentry ISOLOKSAH sampler seal design isolates the operator from the process at all times, with the sample captured in the container "locked out" from external influences.
  • The samplers can be used for composite, batch or analysis sampling techniques.
