Hot Sell Laboratory KW-4A Spin Coater with 500-8500rpm, spin coating machine

This KW-4A is a compact and easy-to-use spin coater for precise and uniform deposition of thin films and coatings. Its rugged, vibration-free and portable design makes it a versatile tool for any high-quality research facility. A two-stage spin process allows dispensing at low speed and homogenizing the coating at high speed. The KW-4A spin coater can be used to deposit metal oxide thin films, polymer coatings and metal organic thin films. With Over 1300 Scientific Publications Resulted from SETCAS SPIN COATERS The Rugged, Portable Vibration-free and Design is Ideal for Research applications. A Two-Stage Spin Process allows dispensing at low speeds and homogenizing the Coating at High Speed.
New features of the KW-4A Spin Coater :

· Prevent the cleaners and solvents travelling down the motor;

· Set speed and time with the keypad, convenient and accurate.

· Take button and start button interlock, prevent the substrate flying out.

· Add theTake/Absorb button to control the start and stop of the pump, reduce the pumpnoise pollution and extend the pump life.

Two stage spin process:
This approach allows dispensing at low speeds and homogenizing the coating at high speed. The KW-4A spin coater can be used to deposit metal oxide thin films, polymer coatings, and organic thin films on a wide variety of substrates including SPI Supplies Silicon Nitride Membrane Windows, Multi-Frame Arrays. The higher the spin speed, the thinner the final spun coating.
The largest substrate, theoretically, would be a 9" (229 mm) diagonal measurement. Normally, the largest standard size chuck for the KW-4A is 6" (152 mm). Some space must be allowed between the wall of the bowl and the substrate to avoid splash back, this being the reason for the maximum size is less than the maximum bowl diameter. A second reason has to do with the size of the motor and the need for a larger motor for wafer sizes greater than 6". If one is working with a very thin wafer, then it can be possible to stretch the unit to its limits and coat an 8" wafer. However, one would need a specially fabricated 8" chuck.
Selection of vacuum chucks:
It is important to order the chuck that seems best for your type of work. We generally recommend the next smaller size chuck that is just smaller in size than your largest substrate. It is imperative that there be no exposed chuck surface, otherwise, the coating liquid will be sucked away into the vacuum system, which of course is quite undesirable. If you are working with samples of various sizes, it might be beneficial to have more than one size chuck. Vacuum chucks are available in aluminum or PTFE.
