Vacuum Heated Pressing Furnace up to 1000C with 4" Quartz Tube - OTF-1200X-VHP4

In Stock
Item Number: OTF-1200X-VHP4
Transported by LTL Freight (Truck)

The OTF-1200X-VHP4 is designed for making dense compound materials under both vacuum and high pressure up to 2 metric tons.  It is integrated with a split vertical tube furnace with a vacuum-sealed 4" quartz tube and  2000Kg digital electric press, as well as one set of 0.5" ID  graphite pressing, die.   The furnace can be heated up to 1000ºC using a temperature controller with 30 programmable segments. Water-cooled flanges facilitate a vacuum level up to 10E^-5 Torr via the use of an optional turbomolecular pump.
Note:  Chang hydraulic press into more precision digital electric press since March 25, 2020
