Seal the quartz ampoule containing the PBN crucible and other items! We will evacuate it using a high vacuum pumping system.
The "MAT-200VS" is a one-zone, two-part quartz ampoule vacuum sealing furnace. It uses quartz ampoules that have been welded together at the top and bottom using an ampoule welding machine in advance. The sealing of quartz ampoules containing molten GaAs polycrystalline, seed crystals, As metal, PBN crucibles, etc., is performed. For more details, please contact us. 【Features】 ■ Uses quartz ampoules that have been welded together at the top and bottom using an ampoule welding machine in advance ■ Seals quartz ampoules containing molten GaAs polycrystalline, seed crystals, As metal, PBN crucibles, etc. ■ The quartz ampoule is placed inside the electric furnace, and vacuum is drawn from the upper thin tube ■ Vacuum is drawn using a high vacuum exhaust system * For more details, please refer to the PDF document or feel free to contact us.
