This video shows a Laurell Technologies WS-650Hz-23NPP spin processor with a fixed central UD-3 dispenser and an off-center UD-3b dispenser.

This combination of a central UD-3 and off-center UD-3b allows you to completely automate a spin coating and edge bead removal process.

The adjustable nature of the UD-3b mounting, and the use of the correct needles, allows you to use it as an additional center dispense unit. Up to three UD-3b dispensers can be mounted on the lid of our 23NPP series system allowing you to spin-coat multiple layers on 150 mm substrates.

Our Universal Dispense units are fully integrated into the system allowing you to program and control them at every step of your process.
