Instrument enables flexible wetting tests

Wetting tests and measurements of the surface free energy on very large samples, on tilted or vertical and on enclosed surfaces - the "MobileDrop" from Krüss has all these possibilities in its program. The instrument in PDA format is operated with only one hand and a notebook and requires a measuring area of only a few square centimeters. Easily exchangeable dosing heads allow the rapid use of different test liquids. The field of application of the instrument has recently been extended by the introduction of the "MobileDrop HT" high-temperature version for measurements on hot surfaces. In the coating test on frying pans, etc., scientific measurements with this version have already replaced the crude "egg-frying" method. A dosing head with accurately adjustable dosing volume is also available, it is intended for use with standardised measurement instructions.
