Vacuum spray pyrolysis coater has stainless steel chamber and molten tin-bath heater. Compares to the regular SS hot plate, the tin-bath heater provides uniform and stable heating to the substrate during the coating process. The SS304 chamber ensures a clean and healthy atmosphere suitable for the most demanding experimental requirements. A software is included for the automation of spray head movement and dispensing rate. A positive displacement pump controlled by a stepper motor is used to dispense solution as per requirement. The ultrasonic spray head ejects fine atmoized solution on substrate and its movement is controlled by the stepper motor driven linear stages in X and Y direction to ensure uniform coating. The spray pattern and velocity can be adjusted by changing the compressed gas pressure at the nozzle.

Vacuum spray pyrolysis coater specifications:

Power Input

• Single phase 208 - 240 VAC, 50/60 Hz

• Actuator: Stepper motor, 24 VDC

Chamber Size

The SS304 chamber provides a working space 700mm×700mm×800mm

Dispenser

• Dispensing unit capacity: 50 mL & 250 mL (two containers included) container
