Spin Coater

Spin coaters are widely used instruments for depositing uniform films on flat substrates. In microfluidics, spin coaters can be used to apply photoresist layers (such as SU-8) or to bond individual substrates utilizing the adhesive properties of PDMS. In addition, they are used to fabricate polymer films, such as PDMS films, and are suitable for fabricating microchannels with circular cross sections.

Alfa Chemistry offers spin coaters for precise, uniform deposition of thin films and coatings. Their rugged, vibration-free and portable design makes them versatile tools for your research facility. The two-stage spinning process allows for low-speed dispensing and high-speed homogenization of coatings.
