Product details

Attension High Pressure Chamber is an advanced add-on module for Attension Theta, enabling to perform interfacial tension and contact angle measurements in high pressures and temperatures.

The chamber includes a unique piston design which is especially useful in any studies including surfactants. Traditionally, the pressure is increased within a chamber by pumping more fluid into it. However, when surfactants are used in the measurement this will lead to a situation where surfactant concentration will also change while changing pressure.
In order to eliminate the issue, in Attension High Pressure Chamber the pressure can also be increased by using a movable piston inside the chamber. The piston will compress the fluid in the chamber without the need to pump in more fluid. Therefore, both surfactant concentration and measurement pressure can be controlled independently.
Attension High Pressure Chamber is operated with modern OneAttension software. OneAttension includes features such as

  • Automatic baseline detection and drop shape fitting
  • Live analysis of results
  • Ready-made experiment recipes for quick and repeatable operations
  • Flexible and programmable frame per second rate recorded by the camera

The chamber itself is CE-marked and made from high quality stainless steel. It is easily removable for cleaning purposes.

Application example

Wettability of CO2 in Enhanced Oil Recovery (EOR)

In order to gain the maximum yield from an oil reservoir, methods grouped under the name enhanced oil recovery (EOR) are used. One common EOR method is to use CO2 to both dissolve and displace oil in a reservoir.

To study the effectiveness of the CO2, the wettability of it can be measured by using interfacial tension and contact angle measurements. The interfacial tension between CO2 and brine, for example, correlates with how easily carbon dioxide can be pumped into the reservoir. Likewise, the contact angle of an oil drop in a carbon dioxide environment gives a measure how well the CO2 can displace the oil on rock surface.

For more detailed information about using CO2 in enhanced oil recovery, see:
