Density

​

AccuPyc II 1340 - Pycnometer - Gas Displacement Pycnometry System

Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. This technique is non-destructive as it uses the gas displacement method to measure volume. Inert gases, such as helium or nitrogen, are used as the displacement medium. Density calculations using the gas displacement method are much more accurate and reproducible than the traditional Archimedes water displacement method.

Contact Angle​

​

OCA Series

The contact angle measuring and contour analysis systems of the OCA Series are capable of determining the wetting properties and the surface tension of liquids.

Dynamic Contact Angle & Tensionmeters​

​

DCAT Series

The dynamic contact angle measuring instruments and tensiometers of the DCAT series are the all-purpose instruments for the weight-based measurement of contact angle, surface and interfacial tension, critical micelle formation concentration, density, sedimentation and penetration rate.

​

The DCAT systems are adaptable to a multitude of measurement settings with different sample holders and extensions. The highly precise weighting technology makes sure that the results are conforming to international standards.

Video-based Spinning Drop Tensiometer SVT​

​

SVT Series

The Spinning drop video tensiometers of the SVT series are compact optical measuring instruments for the determination of low to ultra-low interfacial tensions and rheological interface properties.

Stability Analysis Systems​

​

MultiScan MS 20

Measuring device for the automatic optical stability and aging analysis of a variety of multi-phase dispersions, in particular suspensions and emulsions, and the comprehensive characterization of time- and temperature-dependent destabilization mechanisms. Due to its modular design the MS 20 can be operated with up to six scan towers ST. The scan towers are independently controllable, which allows to perform several measurements simultaneously.

Humidity Generators and Controllers​

​

HGC 20 - HGC 30

The Humidity Generators and Controllers HGC is designed for the automated regulation of the relative humidity for a wide range of applications. It is easily connectable to many environmental chambers of DataPhysics Instruments and other suppliers.

Surface Profile Analyzer

​

SPA25

The Surface Profile Analyzer SPA 25 can measure surface topography and roughness parameters with exceptional speed and resolution.
