GC Granucheck sampler

The GC sampler is primarily for taking samples from free-flowing, granular bulk materials and coarse powders under normal atmospheric conditions, or in an overpressure range up to 1 bar (g).


  • Can be switched to continuous or non-continuous operation as needed, allowing the desired sample size to be freely adjusted by means of the sampling duration
  • Two sizes available, for sampling of bulk material up to approximately 8 mm in diameter
  • Welded-on connecting pieces available for 45°/60°/75°/90° and with three different stroke lengths, to suit your requirements
  • No separation of bulk material during sampling
  • Bulk material removed from moving or non-moving bulk material column
  • Durable and low-maintenance due to design features and materials used
  • No bulk material deposits as, in its resting position, the sampler probe is completely flush with the vessel or pipe wall
  • Direct monitoring of the position of the piston by means of proximity sensors
  • Electro-pneumatic drive
  • Direct installation possible, as the system is delivered pre-piped and pre-wired for a terminal box
  • Stainless steel construction of parts in contact with bulk material
  • Welded-on connecting materials available in various materials, allowing for mounting on stainless steel or aluminum vessels.
  • Aluminum outlet flange with recessed stainless steel pipe
  • Robust, compact design and recessed seals enable use in pneumatic conveying lines up to 1.0 bar (g), mechanical design of -1.0 to 10.0 bar (g)
  • High mechanical temperature resistance from -20 to +120°C
  • Flange joints bored in accordance with DIN 2501 PN10 FF or ANSI 150 lbs FF
  • Declaration of incorporation or declaration of conformity in accordance with the Machinery Directive and declaration of ATEX conformity available
