Vicat Dry – no more irritating oil fumes

Vicat Dry instruments feature easy, convenient operation and are used primarily in research and development, goods inwards checks and production monitoring. The oil-free measuring principle ensures clean, odor-free working conditions. The test sequence is completely automatic. Different versions of the instrument are available, with two or six testing stations according to requirements.

Key Advantages and Features

  • no fiddling with weights - loading is performed automatically
  • convenient PC control
  • instrument cools down quickly, assisted by a cryostat with closed coolant circuit
  • easy displacement calibration using gage-blocks
  • space-saving
  • small specimens are easy to handle
  • rapid re-cooling enables significant increase in throughput compared with oil Vicat tests


  • Determination of Vicat softening temperature (VST)
  • of thermoplastics as per ISO 306

Functions, elements and interfaces

  • built-in microprocessor-controlled electronics for temperature control and measured-value acquisition
  • fully automatic test-sequence
  • automatically controlled compressed-air re-cooling
  • connection for fluid cooling
  • safety thermostat
  • low heating of housing
  • safety switch prevents crush risk
  • serial interface for connecting a PC for test-control and data acquisition via ZwickRoell Roell testing software
  • integrated compensation for heat expansion
  • integrated weight sets, 10N and 50N

Automatic test sequence

Once the heating block has reached the starting temperature, the specimens are positioned in the measuring stations, the instrument is closed pneumatically and the test weight specified in the standards is automatically applied.

On completion of preheating under the influence of force, the displacement signals are zeroed (program-controlled) and warming of the heating block at the preset rate is started. As soon as the required penetration is attained at all stations, the heating is switched off and the test is ended.

Re-cooling is started automatically; the specimens can afterwards be removed.

Recooling the heat-transfer liquid

The instruments are equipped with compressed-air cooling as standard. If sufficiently cool compressed air is not available, the instruments can be cooled with water.

Testing of 3D-printed components in the plastics industry

3D printer plastics components, in addition to prototype construction, are increasingly being used in production. With this versatile process, new products are continuously being developed and existing components are optimized. To reduce testing and analysis expenses and establish industry recognized test standards for development and production, Cubicure in Vienna, Austria relies on testing technology from ZwickRoell.
