Used Laurell WS-650HZB-23NPPB Photoresist Spin Coater

Laurell WS-650HZB-23NPPB Photoresist Spin Coater The Laurell WS-650-23 B spin coater is compact and packed with advanced features. This 650-series coater system will accommodate up to ø150mm wafers and 5" × 5" (127mm × 127mm) substrates and features a maximum rotational speed of 12,000 RPM (based on a ø100mm silicon wafer). The closed bowl design, coupled with the precision of the process controller, allows most coating materials to dry in a quiescent state, increasing uniformity and minimizing particle contamination. The upper plenum closes inside the base to provide an overlapping seal, and the inside of the lid has a special gutter to channel fluid to the rear of the system to discourage chemicals from accidentally dripping onto the substrate. Includes optional Syringe Pressure Regulator. 100-240V, 50/60Hz, 3.2A
