Oyster™ Samplemaster is a non-intrusive sanitary piston valve designed for safe, hygienic sampling of powders and granules by gravity from process equipment—without disrupting the vessel’s internal temperature, pressure, or vacuum. Ideal for vacuum dryer applications, this valve ensures product integrity during sampling.
The design can be customised with various mounting options for integration with the host vessel, as well as multiple sample bottle connection types to suit process requirements.

All Oyster™ sanitary valves are built in compliance with cGMP standards, ensuring dependable performance, minimal maintenance, and optimal hygiene. Precision engineering eliminates hard-to-clean recesses, while every unit is manufactured to exact tolerances and polished to the highest pharmaceutical-grade finish.
