This model has a blue light (405 nm) LED flood curing chamber to cure the coating after the dip process. The curing light intensity can be programmed from 1% to 100 % in 1% increments. A wait time after the dip, and before the curing, can be programmed. The flood curing chamber is made to prevent light leaking out to the main chamber to protect light sensitive solutions from deterioration. Valves are provided to purge the curing chamber and the main chamber with inert gas. The LEDs are cooled by circulating water through their heat sink. An immersible pump is supplied along with the instrument for this purpose. Sample holders customized according to the sample dimensions, material and shape are available.
Holmarc’s Dip Coating Unit has been designed in such a manner which minimizes the operator’s effort. The variables like speed, duration, etc. are maintained accurately by computer control. Dip-coating process, includes five stages: immersion, start-up, deposition, evaporation and drainage. The coating thickness depends on various parameters like viscosity of the coating solution, immersion time, withdrawal speed, evaporation rate etc.
Movements are achieved by a precision servo motor controlled linear stage. Adjustable stroke length and accurate speed control are the exceptional features of this model along with its capability of achieving a uniform coating. This is a compact, bench-top coating unit having structural rigidity and is free from vibrations.
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. Both manual mode and PC mode are possible in this equipment. In manual mode a user friendly front panel with keyboard and LCD display is provided to enter all the dipping and drying parameters where as in PC mode entire unit can be controlled by user friendly software.
It can store up to 5 programs in manual mode, which are editable during the operation. The system is complete with its mechanics, electronics and software. Customization can be done in order to suit the developing needs of the user.
