Spin Coating Unit

with Polypropylene body

Model: HO-TH-05GV

Holmarc’s Spin Coater, Model no: HO-TH-05GV is a dedicated tabletop system to spin coat small substrates in research laboratories with well controlled spin process parameters. The high speed and duration range allows the user to achieve the desired thickness or thinness of the film. The spin head actuator is a precision DC servo motor, which requires less maintenance, with accurate speed and acceleration control. A vacuum chuck powered by oil-less vacuum pump holds the substrate at the spinning head.

The device has user friendly front panel having 5 inch touchscreen LCD for programming the spin process. Spin duration, spin speed, acceleration, etc. are all programmable parameters through the front panel. As the program memory is non-volatile, the recorded parameters are not lost in case of any power failure. This model is equipped with a memory for unlimited number of pre-set, editable programs, each having 10 steps.
