Characteristics: sampler 4210
Compared to the standard samplers, the special sampler for sampling of faecal matter is equipped
with a rinsing unit in the metering vessel and an additional outlet. Furthermore the sample is filled
directly into the bottles. The section from the metering vessel to the distributor outlet is rinsed.
Method of operation:
The metering vessel is rinsed automatically after each sample extraction.
To do this, the distributor arm first moves on the discharge position and
then back on the bottle. Thus a sample contamination is avoided.
The picture shows the metering vessel with additional rinsing water
connection.
The rinsing head (arrow) can be seen after having removed the
metering vessel.
The picture shows the distributor unit:
1. Detailed view of discharge position when rinsing.
2. Distributor arm with direct dosing.
