Universal Surface Tester with high local resolution for deformation, damping, topograpy, microfriction and many more
Universal Surface Solution within One System
UST® is designed to deliver quantitative mechanical characterization within one open platform. It serves best to the R&D center of our industrial partners and research institutes all over the world. Built on a patented measurement protocol, the UST® provides an essential and reliable solutions within the nanometer and centimeter range.
UST®– Universal Surface Tester, is the only open multi-modular system that provides a complete mechanical testing solution for the evaluation of bulk materials and surface coatings. Over 10 measurements can be accomplished and over 60 different test tips have been developed to meet the diversity of your characterization requirements.
The basic unit of UST® has two versions: UST® 100 (loading range 1mN-100mN) and UST® 1000 (loading range 100mN-50N). The basic unit consists of floor-stand cabinet, measurement head with 3 tips, automatic X-Y table and data acquisition system.
Among various kinds of commercial available in-line material property testing instruments, UST® is by far the only tester which closes the gap between the traditional macro-mechanical testing machines and nanoscale machines, e.g. AFM.
High precision load sensor combined with piezo actuator and active feedback loop control for real-time measurement of normal load and friction force

Real time data acquisition with full integration of images, data and graphics
Easy sample preparation and tip exchange
Customized tip choice for various applications
Compatible with various environments: liquid, or humidity
The UST® measurement procedure consists of a mechanically scanning by a stylus on the sample surface along a straight line several times. During this patented MISTAN® procedure, the stylus is moved on the surface either without load or with a defined load.
Step 1: Scan with no load. Surface structure is continuously determined.
Step 2: Scan on the same path with additional load to determine total deformation.
Step 3: Scan on the same path with no load to determine the elastistic deformation.
Total deformation = Step 1- Step 2;
Elastic deformation = Step 3 – Step 2;
Permanent deformation = Step 1 -Step 3
