Pressure-vacuum principle: Highly accurate sample volume

The sampler functions according to the pressure vacuum-principle and operates in time, volume (flow-proportional), or event-based mode. Compared to peristaltic methods the pressure vacuum technology ensures high volume accuracy (due to dosing vessel). There is no wearing out of the sample tube.

Lightweight, corrosion-free PE housing

The temperature controlled, weatherproof housing made of PE plastic ensures failure free operation over many years. Even under conditions where stainless steel usually corrodes.
Depending on the configuration the sampler's weight is approx. 60kg. Therefore installation locations can be changed without difficulty.

Tropicalised cooling system

The tropicalised cooling system ensures a sample storage at 4 °C up to an ambient temperature of 43 °C.
Thus the sample is refrigerated to exclude biological and chemical changes. To avoid cross contamination, the system is rinsed before and after each sample is taken.

Cost effective to buy and maintain

No consumables are needed.
Maintanance free pressure vacuum technology plus maintanance free motor driven valve system & motor driven pinch valve. It is not necessary to change the pump tubing or other pneumatic parts periodically.

Easy to clean sample container

Cleaning of the multiple bottle sample container takes 50% less time compared to wedge shaped bottles.
