The DCAT 9 has been completely redesigned from scratch. The core, a high-precision electrodynamic compensation weighing system, surrounded by state-of-the-art, modular electronics, enabling for example in conjunction with new stepper motors a sample stage positioning speed of 46 nm/s to 12 mm/s.The also completely redesigned software is operable tradition-ally, using mouse and keyboard or with multi- touch notebooks/pads by finger/pen.

Measuring methods• measurement of the static, time- and temperature-depend-

ent surface and interfacial tensions according to the Du Noüy-ring and the Wilhelmy plate method

• Lamella breakpoint test to determine the surface elasticity• automatic ring corrections according to Zuidema & Waters,

Mason & Huh and Harkins & Jordan• gas-, liquids- and solids data base• determination of the density of liquids
