Control Model:


MSK-USP-05 is the latest model (upgrade from MSK-USP-04) in MTI line of Spray Pyrolysis Units. It is the larger version that provides expanded capacity and increased travel area for the spray head. This also provides a larger heating platform to spray coat substrates that are larger than the standard application. This model uses a fresh new design that enables the user to carry out the spray coating process in a more convenient and efficient manner. Also, it can be separated from the bottom shelf section for use as a table top unit. This unit also provides for Nitrogen purging of the enclosure. The parameters of the ultrasonic spray pyrolysis ( USP) equipment, like dispensing rate of the solution and the speed of spray head movement, can be precisely controlled by program. A positive displacement pump controlled by the stepper motor and microprocessor is used to dispense solution as per requirement. The ultrasonic spray head provides thinner particle coating and its movement is controlled by the stepper motor driven linear stages in X and Y direction to ensure uniform coating. The temperature of the substrate heater plate is controlled independently through a dedicated controller.

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 a long period for applying a transparent electrical conductor of Tin oxide (SnO2) or Stannic oxide to the glass. Now is popular to prepare perovskite solar cell.

 Power Input Single phase 208 - 240VAC,  50/60Hz
 Actuator Stepper motor, 24VDC


  • Three Spray heads are included: 
    • Ultrasonic spray head: for thinner film coating
    • Compressive air spray: for thick film
    • 20ml Syringe Pump with compressive air for the expensive solution of the thick film.
  • Dispensing unit capacity:   50ml & 250ml ( two containers included )
  • Dispensing rate:  1-10ml / sec. adjustable via software.
  • One brand new laptop computer or one Microsoft Surface Pro with pre-installed software is available for controlling. (Please select at the optional bar)

  • Ultrasonic atomizer nozzle: 40 KHz, 130W
  • Producing a fine spray of droplets of 50 microns average size
  • Fluid viscosity range: 1 - 50 mPa·s (cP)
  • Sprayer traverse:  X - Y 250mm max.
  • Drive speed X axis (min-max): 10-800mm / sec
  • Drive speed Y axis (min-max):  1-12mm / sec
Pressure Regulator & Gauge

  • Pressure regulator with digital gauge is installed on the machine for precise air pressure control. 
  • Digital pressure gauge is operated by 3V lithium battery ( included )

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 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.
