ComPrep steady force add-on

Add-on for the pressure frame ComPrep to allow for spring-loaded experimental conditions. Optional: force sensor

The ComPrep can be used to operate cylindrical CompreCells under pressure, for sample pre-pressing in CompreCells and for sample removal if necessary.


  •  Compatible with all types of cylindrical CompreCells

  • Allows for measurements under spring-loaded conditions to minimize pressure changes induced by volume changes of the sample

  • Progressive spring stiffness to achieve smaller force deviations for the same deflection when subjected to smaller forces

  • Electrically insulates the test cell

  • Optionally included force sensor to measure the applied forces.


Typical applications

Upgrade the ComPrep to a spring loaded pressure frame with the option to actively measure the set force with a force sensor.

  • EIS or cycling of CompreCells under constant pressure in temperature chambers

Detailed Description

The ComPrep steady force add-on is designed to be used in the ComPrep with compatible CompreCells like CompreCell 6/12 and the CompreCell 6/10/12-DP as well as the three electrode options.

It reduces the overall stiffness of the ComPrep to maintain steady forces.

The option to include a force sensor enables the setup to actively measure the set force precisely. Then there will be no need to rely on the correlation between force and torque.

  • Maximum applicable force:

Fmax: 23 kN / 10 kN / 2 kN

  • Temperature range (environment) during operation (ComPrep in climate chamber): 

Toperation/CompreFrame = -30 °C to +90 °C when being operated in climate chamber

  • Temperature range during storage: 

Tstorage = +10 °C to +40 °C

  • Relative humidity range during operation and storage: 

0 to 80% (non-condensing)

  • Atmosphere during storage: 

non-corrosive

  • Total weight: 

approx. 1,3 kg
