Spectrochem instruments is engaged in manufacturing a wide array of special accessories and instruments required in analytical chemistry, medical and biotechnology, lab and process automation, environmental engineering. The company is now offering an automatic continuous chemical vapour deposition unit for pyrolytic coating. The systems are provided with computer controlled filament winding and unwinding system, gas controlled system for pyrolosis of carbon and selane. There is fresh airflow monitoring devices in the three-component gas control system, which help to select various gas compositions at different flow rates. Two such experimental systems have been designed fabricated and delivered to the ceramic group of defense metallurgical research laboratories, for a certain aeronautical component project. Project was conceived and completed in three months.
