Transported by LTL Freight (Truck)

Product Options

Control Model:

    Spray pyrolysis is a process in which a thin film is deposited by spraying a solution on a heated surface, where the constituent reacts to form a chemical compound. The process is particularly useful for the deposition of oxides and has long been a production method for applying a transparent electrical conductor of Tin oxide (SnO2) or Stannic oxide to a glass substrate. Now, this technique is increasingly used to prepare perovskite thin film, such as in perovskite solar cells.
    MSK-USP-02 is a desktop ultrasonic spray pyrolysis (USP) equipment, where parameters like dispensing rate of the solution and speed of spray head movement are precisely controlled by a software interface. A positive displacement pump controlled by a stepper motor is used to dispense solution as per requirement. The ultrasonic spray head provides thin-film coating 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 air pressure at the nozzle. The temperature of the substrate heater plate is controlled independently through a dedicated controller.

Power Input

  • Two Spray heads are included 
    • Ultrasonic spray head (compressed air assisted) for uniform, thin-film coating ( Higher viscosity )
    • Compressive air spray for thick film coating
  • 20 mL syringe pump with compressive air nozzle for thick film coating of small quantity solution. ( Low viscosity <3000)
  • Spray head travel distance: 150mm (Lowest) to 250mm (Highest), 200mm (X-axis) and 235mm (Y-axis)
  • Dispensing unit capacity: 50 mL & 250 mL (two containers included) container
  • Container dispensing rate: 1-20 mL/min adjustable via software
  • Syringe pump dispensing rate: 20 μL/min - 10 mL/min adjustable via software
  • One brand new laptop computer or one Microsoft Surface Pro with pre-installed software is included. (Pls select at the Product Options)

  • Ultrasonic atomizer nozzle: 40 kHz, 130 W

  • Drive speed Y-axis:  1-12 mm / sec
  • Note: you may use inert gas or compress air to shape the spray pattern and increase spray velocity
Air Compressor
  • Compressed air with a pressure of ~ 4 bar is required for normal operation of the unit
  • One compact air compressor is included for immediate use
  • Attention: If a gas cylinder is used instead of an air compressor, a two-stage pressure regulator(pic1) must be installed
