EQ-VTS-1 is a rotatable vacuum ampoule sealing device that is designed to seal the sample in a quartz tube ampule under vacuum at easy and higher efficient yield via oxyhydrogen gas or other flammable gases. This is an excellent tool for preparing thermoelectric materials samples and growing two-dimension crystals that are sensitive to air or easily evaporate. SPECIFICATIONS Power 110 - 240V AC, 50/60 Hz 24VDC Motor, 50W Feature Sealing of tubes for vacuum or inert gas protection Different sizes of tube fittings can be customized and accommodate vacuum sealing on the different tube diameters Unique rotary seal flange and the adjustable digital rotation speed The body can be tilted up to 90 degrees for vacuum sealing of long tubes up to 1m Spinning Speed 0-30rpm adjustable parameter Vacuum Fitting One set of quick vacuum clamps for φ20mm OD tube is included (please contact us for the different sizes) Optional size fittings for vacuum sealing of different outer diameter quartz tubes KF16 feedthrough to connect different quartz tubes. Sealable tube size Quartz Tube Quartz Block The standard package includes: one 20mm OD x 16mm ID x 200mm L single-ended straight quartz tube one 20mm OD x 16mm ID x 200mm L single-ended indented quartz tube two corresponding quartz blocks Optional package: Quartz tube 45 mm OD × 40 ID × 500 mm L and 39 mm in dia. quartz blocks Other sizes of SS adapters, quartz tubes, and quart blocks can be customized, Ø8 ,Ø10, Ø12, Ø12.7, up to Ø45mm, tube length: 100-500mm. The minimum order quantity of the tubes and blocks is10. Intake and Exhaust Components Includes Three KF25 vacuum interfaces One KF25 bellow tube One KF25 Vacuum Right-Angle Valve One φ6.35mm ferrule inlet and outlet One mechanical pressure gauge One KF16 adapter for connecting with quartz tubes. Optional Vacuum Pump A vacuum Pump is not included, please click the picture below to choose a vacuum pump Vacuum level: Mechanical Pump 10 -2 torr, and turbopump 10 - 5 torr Max. Flammable Gas and Torch To melt a quartz tube, you need Acetylene, oxy-hydrogen gas, or liquid natural gas with oxygen Burning torches are available from the local hardware store or Amazon, which is not included Please always consult the safety regulations to choose a flammable gas in your lab Acetylene + Oxygen: ~ 3300 Max Oxyhydrogen gas: ~ 2800 Max. Liquid Nature GasLNG+ Oxygen: ~ 1990 Quality Certification CE Certification NRTL or CSA certification is available upon request at the extra cost
