Holmarc’s Multiple Dip Coater (Model No: HO-TH-02MD) comes with six beaker holders. The dip-coating solution beakers can be positioned in a circle about a rotating arm of the dip coater. Hence, it is possible to coat different solutions alternatively.
It has been designed to keep operator involvement as minimum as possible so that variables like speed, duration, etc. are maintained accurately by computer or microprocessor controller. Movements are achieved by a precision servo motor controlled stage.
Dip-coating process includes five stages: immersion, start-up, deposition, evaporation and drainage. In the dip coating method, the substrate is slowly dipped into and withdrawn from a tank containing the solution, with a uniform velocity, in order to obtain a uniform coating. This device allows multiple dipping of the substrate in different solutions.
A microprocessor based system along with user friendly software takes care of accurate control throughout the process. Speed, traverse and idling duration can be programmed. The system is complete with mechanics, substrate holder, electronics and software.
