WS-650 Spin Coater / Universal Spin Processor


This advanced research and development tool is flexible, safe and affordable. The WS-650 Spin Coater series is typically employed for Solvent, Base or Acid-based processing: Coating, Etching, Developing, Rinsing-Drying and Cleaning. Many dispense options both manual and automatic available.

Continue to upgrade your system indefinitely without returning to the factory with our modular "Back-Pack" kits. While all of these process are supported, Laurell recommends single-use only because of known material conflicts, for example, Photoresist and Developer (cross contamination) and SC-1 and SC-2 (HCl + NH4OH creating NH4Cl, a hazardous inhalation risk).
