Vacuum and Gas Sealing & Flange	Right flange: Water cooling structure with 12mm quick connector to prevent sealing o-ring from melting (water cooler is not included, please click water chiller to order) KF25 vacuum fitting (to the vacuum pump, please click to order a pump,  vacuum hose, valve and sealing gasket) Slidable to easily and fast push/pull in/out the sample One quartz wafer holder ( 3" Dia. max.  ) is built in the flange with heating radiation block for CVD growth on a thin substrate An anti-corrosive capacitance diaphragm gauge is included Left flange with four 1/8'' Swagelok fittings for 1/8'' gas tube: Two separate 1/8'' fitting on the flange for any gas into the CVD furnace   and customized feedthrough is available upon request.
Laptop, software & WiFi Control(Optional)	Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) Labview Based Temperature Control System (MTS01) enables users to edit temperature profiles, manage heat-treatment recipes, record, and plot data for MTI furnaces. A wireless remote control provides up to 300 meters of operating range. The above features are available upon request at an extra cost (up to $1,000). Please contact us for more information. Note: The software is only compatible with MTI’s Yudian Temperature Controller
Compliance	CE Certified NRTL or  CSA or TUV certification is available upon request at extra cost.
Warning	The tube furnaces with quartz tube are designed for use under vacuum and low pressure <0.2 bars / 3 psi / 0.02 Mpa Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Please click here to learn how to install the gas regulator. Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C  The flow rate for gasses should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
