A quick view

This 2-minute video provides you with the basics of measuring under high pressures and high temperatures with Theta High Pressure. Watch it in fullscreen for the best experience! 

3 reasons to invest

Optimal for surfactants and brine

With the integrated piston you can increase the pressure without adding more fluid. This allows you to to keep the surfactant concentration constant and corrosive fluids are restricted to the chamber only.  
 

Easy to use

Theta High Pressure has plenty of smart solutions simplifying your work. The sample port enables direct introduction of your sample with a syringe and direct cleaning of the same sample line without passing through a pump. With our optional automatic pump the pressure can be changed with just one click. 

Intuitive software

Highly intuitive with high functionality. The OneAttension software facilitates your experiments and provide instant results. The software features live analysis and automatic measurements.
