Spin Coater - Embedded chuck for spin-coating on square substrates

Laurell Technologies embedded chucks help you spin high quality coatings on to square or rectangular substrates. See our range of chucks for standard wafers, thin films, and specialist substrates here:

PDMS Spin coating

Spin coating de PDMS (Polidimetilsiloxano) sobre slide de cristal. Spin Coater diseñado y construido en el Laboratorio de Micro y Nanofluídica y Plasma - Universidad de la Marina Mercante - UdeMM. Spin Coater Specifications: Substrate size: Up to 150mm Speed: 200-12.000 RPM Housing material: PVC Main components: - Arduino Mega 2560 - L6234 Three Phase Motor Driver - Turnigy Trackstar 17.5T 1870Kv Sensored Brushless Motor

Spin Coater UD-3b Adjustable Dispenser and Edge Bead Removal

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. For more information please visit
