- The borosilicate glass metering vessel is safely located in the center of the sampler, while an optional lockable cover plate is available to provide further protection if needed.
- With no wearing parts coming into contact with the sample medium, the vacuum sampling system offers consistency and reliability with minimal maintenance.
- A peristaltic pump is also available as an optional sampling system for the WS Porti.
- The WS Porti is compatible with a range of sample transport boxes and coolers which can be easily swapped. Having an extra cooler or transport box with bottles allows continuous sampling on location while the full set of bottles is brought to the laboratory.
- The WS Porti is available for composite sampling or discrete sampling.
