Ultrasonic Spin-Spray Coater VTC-300BUSS is an all-in-one film preparation equipment that combined ultrasonic atomization, spin coating, and drying functions, on a substrate up to 12" (300mm). The liquid is driven by a precision syringe pump with an optional heating function. The ultrasonic atomizer is able to swing over the substrate, thus ensuring the coating uniformity (up to 4 ultrasonic heads). After coating, the film can be heated and quickly dried. The equipment adopts a touch screen control panel, and it can accurately control the parameters such as the ultrasonic power, spray rate, spinning speed, and heating temperature.
.
Applications include thin-film preparation for perovskite solar cells, composites, and flexible films.

|
| Utility Requirement |
- Gas: ~2 psi compressed air for the ultrasonic nozzle. Air compressor is also available for order at MTI
- Attention: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator.
