Compression platens are used in material testing setups to determine the compression properties of materials. ADMET compression platens are commonly manufactured from aluminum or steel and attach to the testing machine with an eye-end connector appropriate for the load capacity. Spherically seated compression platens that compensate for horizontal misalignment of the sample are also available. Browse platens below based on sample size and force capacity and contact us to discuss your testing needs.

CP-SST Self-Aligning Compression Platens

CP-SST spherically seated platens are self-aligning and fixable. They are used with specimens that do not have a parallel surface when placed in between the platens. Once mounted, operators can apply a small pre-load and fix the platen at the required position to start the test.

CP-SSTi platens are Aluminum platens applicable for low-weight compression samples such as packaging materials. CP-SSTk platens are Hardened Steel platens for metal, concrete, and other specimens requiring a higher force capacity.

Standard diameter options include:

  • 56mm (2.2”)
  • 96mm (3.78”)
  • 116mm (4.57”)
  • 156mm (6.14”)
  • 196mm (7.72”)
  • 246mm (9.68”)

Extended force capacities, platen dimensions, high/low temperature ranges, and mounting adapters are also available.
