  The Model STPM-5 is designed for triaxial testing of samples up to 3.0” diameter. It can also be used for flexwall permeability testing of samples up to 4.0” diameter. The chamber is acrylic with circular base which provides a solid support for applying heavy load and also prevents tipping. All aluminum parts are anodized.

The unit is equipped with 2.8" diameter sample caps (acrylic) and porous stones. Other sizes of porous stones are available upon request. Each cap has two drain ports and a grove for scaling the membrane. The top cap features quick connect SS fittings. The pedestal has flow through lines and is keyed to prevent turning during installation.

Standard valves and fittings are brass. Stainless steel valves and fittings, as well as Teflon tubing, are also available on Model STPM-5SS. High quality Whitey ball valves and Swagelok fittings are used throughout.

A stainless steel ground and polished pistons sealed with an internally lubed u-cup noted for its extremely low breakaway friction. A piston lock and dial indicator support bracket is also provided. Stainless steel linear ball bearings guide the piston with minimal friction

Note: Dial indicators are sold separately.
