WS 316 Stationary Sampler

Remarkable Versatility and Impressive Capacity

Whether for indoor or outdoor use, the WS 316 is an all-rounder that impresses with its generous storage space and expandability.

It can be tailored for a wide variety of different sampling requirements and conditions, and can even be retrofitted later with other equipment. The WS 316 even has room for extended bottle sets.

Advantages:

  • Housing and roof made of durable stainless steel
  • Three separate technical compartments in the upper section of the sampler to protect the pump, electronics, refrigeration unit, and other components
  • Freely adjustable and highly accurate temperature control for the sample storage chamber, for ambient temperatures from -25°C to +42°C – optionally from -40°C up to +55°C
  • High-performance vacuum sampling system – alternatively available with any other WaterSam sampling system
  • Borosilicate glass metering vessel protected in sample storage chamber to minimize sample corruption that could stem from temperature extremes
  • Hose inlet on the left and right side; optionally from below
  • Available with a composite container up to 60 l or with an XY Distributor for direct filling of numerous bottle sets (up to 49 x 1l or 64 x 350ml) without cross-contamination
  • Wide range of optional equipment: housing materials, pumps, valves, equipment for challenging sample media and environments, sample freezing, etc.
