KW-4A is a compact and easy-to-use spin coater for precise and uniform deposition of thin films and coatings. Its rugged, vibration-free and portable design makes it a versatile tool for your research facility. A two-stage spin process allows dispensing at low speed and homogenizing the coating at high speed. The KW-4A spin coater can be used to deposit metal oxide thin films, polymer coatings and metal organic thin films.

When purchasing your spin coater, you need to select a vacuum chuck to hold your substrate for coating. Several sizes are available and should be specified by the user. These chucks are machined to close tolerances to assure a smooth spinning process and uniform coating. The chuck selection should be based on substrate size and geometry. Customized chucks are available. Our Mechanical Engineering Department will design and machine special orders at customer's request.
