DSA100HP is our high-quality solution for the precise measurement of contact angle and surface tension and interfacial tension under high pressures and temperatures, primarily for tertiary oil recovery.

The DSA100HP combines our Drop Shape Analyzer – DSA100 for optical drop shape analysis with a high-quality measuring cell for high-pressure applications ranges for 40/690 and 1750 bars . It determines the surface tension, and analyzes the wetting of oil-bearing rock by surfactant solutions under the extreme pressure and temperature conditions found in reservoirs. The results help in the extraction of oil from layers of rock in the most effective manner using tertiary oil recovery (EOR) methods such as steam or surfactant flooding, and thereby increase the yield.

The instrument equally reliably measures the wettability by gases which liquidize under pressure, for example for optimizing extraction processes with carbon dioxide.The precise measurement of surface tension under storage conditions using the DSA100HP is very informative in the characterization of a surfactant solution which is used for flooding a crude oil reservoir. This should be as low as possible to ensure that the rock is well wetted.

Versatile options for dosing and measuring

With the aid of the dosing units of the DSA100HP, the drop liquid and the surrounding phase easily reach the inside of the high pressure cell. 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 250 °C is achieved by means of an electric heater.

Reliable drop shape analysis thanks to high imaging quality

The DSA100HP 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.


Measuring methods and options

- Contact angle measurement using a sessile drop
- Surface tension of a liquid in gas or interfacial tension between two liquids using a pendant drop
- Upside-down pendant drop measurement of an oil drop in water

Drop Analysis from a bird's-eye view

The measurment of contact angle on concave surfaces/depressions is a challenge, the Top View AnalyzerTVA100 measures the contact angle from the top using the distance between spots of light reflected from the curved drop surface. This technique allows nondestructive measurements on concave surfaces or surfaces in recesses in which a measurement of the shadow image with the illumination, sample and optics in a single plane is ruled out. The measuring head is available as a module for the well-proven KRÜSS DSA100, DSA30 and EasyDrop instruments and also as an independent portal system for contact-free measurements on large samples.

An overview of the TVA100:

• Evaluation of surface curvature using the mirror images of spots of light
• Measurement on concave surfaces or in depressions
• Robust precision dosing for a wide range of liquids
• Rapid assessment of wetting homogeneity

Available as:

• Top View Analyzer TVA100
• Module for KRÜSS DSA25, DSA30 and DSA100 instruments
• Portal system (TVA100R) for contact-free measurements on large samples Offered angle measuring systems that are based on latest technology and make use of the image of light spots that are reflected by the curved surface of the drop to measure the contact angle.

Applications:

• Biotechnology (microtiter plates / 96well plates)
• Microelectronics (mounted PCBs)
• Wafer techniques
• Sanitary ceramics
• Optics (concave lenses)
• Quality control in surface cleaning processes

Note:
The price will vary depending on configuration and accessories.

Precise wettability analysis on extremely small surfaces.

The Micro configuration of our DSA30 was specially designed to investigate the contact angle on surfaces which require very small drops for analyzing them. The DSA30M solves this task with a picoliter dosing system and powerful microscope optics. The result is a versatile instrument that provides precise contact angle and surface free energy results for samples such as hairs or the screw windings of dental implants.

Tasks and applications

- Wettability measurement on small electronic parts
- Contact angle on hair and synthetic single fibers
- Investigating the biocompatibility of dental implants
- Wetting of nozzles of an inkjet print head

Measuring methods and options

- Contact angle between a liquid and a solid
- Surface free energy from contact angles of two test liquids using all common models
- Static contact angle, advancing angle

Perfectly equipped for microdrop analysis

The available dosing units for 20 or 60 picoliter minimum volume dispense microscopically small drops of test liquid onto the sample. The fine positioning of the dosing unit and the sample allows precise placement of the drops. Working with two test liquids also enables the surface free energy to be calculated. This result provides important information for the adhesion, e.g. of fiber coatings.

Providing optimum image quality for precise analysis

Thanks to the high-quality microscopic lens and powerful illumination, the DSA30M has high image quality that enables reliable measurement results from image analysis. With the help of the instrument’s high-speed camera, even ultra-small, rapidly evaporating drops can be easily analyzed.
