For solid sampling

The Auger Sampler Typ MST 38 / AST 38 / EST 38 are suitable for fitting at downpipes, chutes, hoppers or similar containers.

The sampling system allows continuous, representative and reproducible sampling of variable volumes out of standing, sliding and free falling products. After sampling the sample retains in any collection system which is connected to the outlet with a 1,5” Triclamp (TC).


The device is characterized by its uncomplicated installation and reliable functionality. The sample quantity can be freely determined via the actuation time. In the driven version and with appropriate control, sampling can be carried out in proportion to time, volume or event.

For cleaning the system is easy to dismount and to disassemble by the use of TC-flanges.

The auger sampler is actuated optionally by air motor, electric motor or crank handle. The Auger is made of stainless steel (316L) or Polyamid-Segments (PAS).


A screw conveys the product through the extraction pipe. The sample falls from the ejection nozzle into a sample vessel. The spiral conveyor is driven manually by means of a crank (type M), a pneumatic gear motor or a 24V electric motor. Product residues remaining in the housing are removed from the sampling tube by reverse gear, so that the sample is always "fresh".

Assembly and Installation

To mount the sampler, the TC flange supplied is welded into the wall of the pipe or shaft. The sampler is attached to it with a triclamp. Optionally, a sample collection system can be connected to the ejector. For pressure or vacuum applications, a shut-off device should be installed between the sampler and the collecting container.
