DCAT 15 Tensiometers

DCAT 15 Tensiometer – Modular Surface and Interfacial Tension Measurement System

The DCAT 15 Tensiometer from DataPhysics Instruments is a high-precision, modular system engineered for advanced surface and interfacial tension measurement. Designed for both research and industrial applications, it builds on the success of the DCAT 8T by introducing additional automation, flexibility, and measurement capabilities.

At the core of the DCAT 15 is an electrodynamic compensation weighing system, offering highly accurate and repeatable results. Whether you’re conducting quality control in coatings or advanced studies in pharmaceuticals, this device ensures your data is reliable and precise.

The system features motor-driven sample positioning, automatic coupling locks, and crash protection to ensure the safety of both the sample and sensor. An illuminated sample chamber with an integrated magnetic stirrer and digital thermometer adds further control over experimental conditions.

One standout feature is the DCAT 15’s ability to perform dynamic contact angle measurement, essential for evaluating wetting behavior and critical micelle concentration determination. Paired with the LDU 25 Liquid Dosing Unit, it can automate the generation of concentration series—ideal for studies requiring precise surfactant behavior analysis.

Supported by a suite of software modules (DCATS 31 to DCATS 36), the DCAT 15 offers additional functions including surface energy evaluation, sedimentation behavior, and liquid and solid density measurements. This surface tension analyzer adapts to your specific laboratory needs.

For researchers and engineers requiring reliable, flexible, and highly accurate surface analysis tools, the DCAT 15 Tensiometer is an exceptional choice.

The DCAT 15 Tensiometers enables additional measuring methods and hence can be used to determine dynamic contact angles, the surface energy of solids or sedimentation and penetration properties. In addition the DCAT 15 can be extended with a liquid dosing unit LDU 25 and can thus create sequential concentration series of, for example, surfactant solutions. Without manual user intervention the critical micelle concentration (CMC) can be determined software controlled in a series of experiments.
