TA Electroforce low-force testing grips have a smooth gripping surface suitable for compliant samples.  Typical samples include collagen gels, fibrin gels, or other biomaterials and engineered materials that are fragile and require careful handling.  The grips can be used either in a sterile environment, such as the ElectroForce® BioDynamic® test instrument, or for non-sterile applications in air or in a heated saline bath with an Electroforce 3100, 3200 or Testbench  system.

Key Features

  • 10 N maximum Load
  • Clamp design with knurled screw for locking
  • Smooth grip surface
  • Total estimated weight: 21 grams each
  • 8.4 mm maximum specimen thickness
  • 12.5 mm maximum sample width
  • 12 mm recommended minimum sample length
  • Used in non-sterile and sterile applications including saline baths and BioDynamic chambers
  • Used on Electroforce 3100, 3200, Testbench and BioDynamic test systems

Overview
