The DSA100HP690 performs precise measurements of contact angle as well as surface tension and interfacial tension at pressures of up to 690 bar and temperatures of up to 200 °C. The main focus lies in optimizing the use and formulation of flooding fluids in enhanced oil recovery (EOR).
The instrument analyzes the wetting of rock as well as phase interactions between oil and water under reservoir conditions. The DSA100HP690 combines our expertise in the field of optical drop shape analysis and the know-how of our partner EUROTECHNICA in high pressure applications.

Versatile options for dosing and measuring
With the aid of the dosing units of the DSA100HP690, the drop liquid and the surrounding phase easily reach the inside of the high pressure cell. Handling the drop phase is especially convenient with the special Mini-Dosing unit which works with small volumes and is easy to clean. This dosing unit, as well as the high pressure cell, is also available in the resistant material, Hastelloy for measurements with corrosive reservoir water.
Rock samples can be positioned from the outside to measure the wettability at different positions while maintaining the pressure. The flexible design also allows contact angle measurements in a surrounding liquid phase. Precise temperature control up to 200 °C is achieved by means of an electric heater.
Reliable drop shape analysis thanks to high imaging quality
The DSA100HP690 features a high-resolution camera and a quality zoom lens for accurate display of the drop with optimum size. The high image quality that this achieves leads to a precisely measured contact angle or surface/interfacial tension. Combined with the intelligent image evaluation algorithm of the ADVANCE software, drop shape analysis with the instrument provides exact results.
