Hassler Cell

Hassler cell

For the past 25 years TOP INDUSTRIE has been developing technical means for research centers working in the following areas:

  • Geo-mechanical tests under pressure on soils, rocks, cements and concrete
  • Triaxial tests in fissuring, drainage, permeation, percolation, creep…
  • Measures of displacement, dilatation, flow


In this field, TOP INDUSTRIE proposes a Hassler type cell which is easy to use, inexpensive, it makes permeability tests easy to carry out.

Features of the Hassler Cell:

  • For all pressures between 0 and 600 bar
  • For all temperatures from 0 to 200°C
  • Sample Ø: from 5 to 50 mm
  • Fluids: gas, liquid or supercritical fluids
  • Material: 1.4404 (316L) or Hastelloy
  • Sample viton jacket with probes inserted at the top in order to measure pressure drop
  • Closure through conical shutter and screwed in cylinder head
  • Internal temperature monitoring
  • PED 97/23/EC Compliant


Options of the Hassler Cell:

  • HPMP Pressure generator
  • Confinement pressure control
  • Control of upstream and downstream draining pressures
  • Maximum pressures of up to 1500 bar

Permeability Cell

Permeability cell

Top industrie offers a full range of cells to measure porosity and permeability:

  • Rock Top 10 serie can be used for low pressure, up to 240 (3500 psi)
  • Rock Top 20 and Rock Top 30 series can be used for high pressure, up to 600 bar ( 9000 psi)
  • Can be used at room temperature or up to 150°C
  • All cells include a confining pressure system, only the Rock Top 30 also include a piston with an axial force. Fluid used : water.
  • Samples sizes: 1 inch   1.5 inch( 38mm) 2 inches (50 mm) 4 inches (100 mm)
  • Manual screw closing or bolted sealing depending on the presssure range
  • Body material: 1.4404 (316 L)
  • European comformity accordings to the European Pressure Directive 97/23
