0.0/5 rating (0 votes)

Description

OTF-1200X-S-50-LVT high-temperature vacuum tube furnace is a split tube furnace for heating samples up to 1200°C. KF25 Gas

Outlet and Digital Vacuum Gauge on the right flange connecting a 226L/m Mechanical Pump and Pump Filter while 1/4'' barb gas inlet on the left, allows the furnace to heat the sample in vacuum up to 1E-2 Torr or flowing gas. In addition, OMEGA 1/4’’ O.D K Type Thermal Couple comes to the left flange, can be inserted inside the tube to exactly measure the sample’s temperature by the readout from the OMEGA Calibrator. The precision temperature controller will provide 30 segments of heating and cooling steps with +/- 1 °C accuracy. Specifications

Warranty	One-year limited warranty (Consumable parts such as processing tubes, o-rings, and heating elements are not covered by the warranty, please order the replacement at related products below.)
Application Notes	Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bar  Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a 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 gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube How to set up a ceramic tube and vacuum flange for MTI tube furnaces. For safety, you may consider putting the small tube furnace inside a fume hood. ( click picture left to see )
Certificate	NRTLs or CSA certification is available at extra cost.
