Rotatable Vacuum Ampule Sealing Device for 20mm O.D Tube - VTS-1

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.
