Sentry ISOLOK SAA Automatic Fixed Volume Sampler

Part #

The Sentry ISOLOK SAA automatic point sampler provides representative samples of liquids and slurries such as waste acid, resin bead slurry, bauxite mud and raw municipal sludge. Ideal for chemical process sampling, waste effluents, petrochemicals, food and pharmaceuticals. The ISOLOK SAA sampler operates when compressed air forces the plunger into the process line to capture a fixed volume of material. Compressed air then acts on the opposite side of the piston to retract the plunger to a position which allows the sample to drop by gravity into a container.

The Sentry ISOLOK SAA sampler seal design isolates the operator from the process at all times, with the sample captured in the container "locked out" from external influences. Metal parts of the sampler are made of 316 stainless steel; other alloys are available for varied applications and process conditions. Process contact seals are filled Teflon for chemical applications or wear-resistant elastomers for abrasive slurries. Modular components allow selection of various bodies and plungers to meet different process applications.
