Triaxial Cells

Product Code : Cells

GDS produce an extensive range of triaxial cells in order to satisfy the complex range of tests required by today’s modern geotechnical laboratories.

Traditional passive triaxial cells (known as passive due to the fact that they are used with an external actuator such as a load frame to apply axial loads), large diameter triaxial cells (up to 500mm sample diameter), active triaxial cells (based on Bishops and Wesley’s original hydraulic stress path apparatus and include an actuator ‘built in’), as well as cells specifically designed for dynamic triaxial testing with low friction bearings and seals are available from GDS. In addition, there are a number of features such as balanced ram triaxial cells, access ports and access rings for internal transducers that are offered.
