Vacuum is provided to the VLTP via three (3) adjustable vacuum venturi device at ~22″ Hg through small orifices on the plates top surface separated into three (3) zones. Fiberoptic back-lights (typically 2-4) provide illumination to the VLTP from adjustable light sources contained in the UDP system. The standard VLTP size has a work envelope of 18″ X 14″ but larger or smaller sizes are available upon request.

The VLTP is generally used in conjunction with the Zmation, Inc. Universal Automation Platform for dispensing applications.
