Spinning Drop Tensiometer – SITE100
Measurement of low interfacial tensions for characterizing emulsions
Our Spinning Drop Tensiometer – SITE100 measures the interfacial tension between two liquids by analyzing the video image of a drop in a rotating capillary. The software-controlled instrument specializes in the precise and simple measurement of extremely low interfacial tensions down to 10‑6 mN/m. The measuring results help you to develop and optimize emulsions and microemulsions.
Several samples in a short time
Our SITE100 is aimed specifically at high sample throughput, and, with the integral capillary, enables samples to be changed particularly quickly. We have developed an optional, matching dosing module, which reduces the sample quantity to only a few milliliters and thus enables minute sample quantities to be measured. The dispensed drop is moved into the camera image in seconds using the instrument's finely adjustable tilting device. The rotational speed of the capillary and the illumination can be conveniently adjusted directly on the unit or by means of the software.
