Sentry ISOLOK MSC Automatic Fixed Volume Sampler

Part #

The Sentry ISOLOK MSC automatic point sampler enables representative sampling of medium-viscosity products such as cream or single-strength orange juice. The ISOLOK MSC sampler delivers a fixed volume of sample with each cycle and includes direct mounting of wide-mouth labware plastic sample collection bottles (available in a variety of sizes). This sampler is conformant to 3-A Sanitary Standards (third-party verified) with a reliable, sanitary, easy-to-clean design with FDA-approved seals.

The sampler mounts onto the process line using a two-inch tri-clamp ferrule mount held with a clamp and gasket. Compressed air drives the sampler by forcing the plunger to reach into the process to capture a fixed volume of the material. Compressed air then acts on the opposite side of the piston to retract the plunger to a position that allows the sample to drop into a container. The operator is isolated from the process at all times by the sampler’s seal design, and the sample captured in the container is locked out from external influences to provide a truly representative sample.
