Although each sleeve can be used for several tests, an order of five spare sleeves is recommended.

Measurements of axial and radial strain are carried out with the use of electric strain gauges, both in vertical and horizontal direction, directly glued on the lateral surface of the specimen. The wiring connections are passed within the rubber sleeve  trough the cell body and loading cap. Each strain gauge must be connected to a proper device to complete and balance the Wheatstone bridge. The strain gauge measurements can be performed by automatic testing systems, or by a suitable datalog. The cell pressure and saturation pressure for permeability tests are carried out by the use of appropriate equipment.

It is also recommended the use of a Specimen extruder, to extrude the rock sample from its jacket thus avoiding to empty the confining fluid.
