Drop Shape Analyzer Wettability of microscopically small surfaces by almost any liquid Determine the wettability of very small surfaces using standard test liquids - or find out how microdroplets of your individual formulation, for example an inkjet printing ink, wet the sample. The Drop Shape Analyzer - DSA30M Flexible Liquid dispenses picoliter drops of the liquids and determines the contact angle as a relevant measured variable when wetting and coating processes on tiny surfaces are to be optimized. ■ 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

The dosing unit places tiny drops down to a volume of 10 picoliters on the sample, whereby even liquids containing particles such as paints or blood can be used without any problems. The instrument's uncomplicated disposable cartridge system ensures quick changes between several liquids. No cleaning or maintenance is required as the dosing tip is part of the cartridge. This means that even heavily soiling or hardening liquids can be dispensed. Whether you want to determine the surface free energy with several liquids or investigate the wetting of a whole range of formulations, the DSA30M Flexible...
