World-Class CVDs

Qrystal CVD:  A fully Automated Research Grade Chemical Vapour Deposition System

With 12 independent temperature zones (divisible into 1, 2, or 3 zones on the fly), each capable of reaching temperatures upto 1200 °C.

It has an inbuilt precision mass flow controller allowing controlled injection of upto 4 gases. A back pressure regulator allows a fixed controlled pressure to be maintained throughout the deposition chamber.

Product Info

The QRYSTAL: Chemical Vapour Deposition system was launched by Quazar Tech in 2018 and has already been deployed at the top research facilities across the country.
Researchers can take advantage of the modular nature of QRYSTAL to build a system as per their research program or procure recipes along with application specific systems kickstarting their research from day 1 of the installation
