Sample checking with the handy VPE

Table-top unit for visual sample inspection of liquid products for particles and cosmetic defects

Method of operation

The containers are placed individually in the holder, which will be rotated at a steplessly adjustable speed. Particulate impurities in the liquid are whirled up. A highly concentrated light directed through the bottom of the container, which is steplessly adjustable in its intensity, causes reflections of the particles (similar to the Tyndall effect); these are easily detectable using a magnifying lens. For cartridge and syringe inspection, a steplessly adjustable, polarised background light can be applied instead.

The advantages

  • A wide range of containers and sizes up to 100 ml
  • Compact design, low weight, very easy handling
  • Light through bottom of container, steplessly adjustable intensity, plus polarised background light, also steplessly adjustable
  • Rotation speed steplessly adjustable
  • Magnifying lens, 4 dpt
  • Fast, toolless format changes
