Description
EQ-VTS-1 is a rotatable vacuum ampoule sealing device which is designed for helping research to seal the sample in 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 sample and grow two-dimension crystals which are sensitive to air or easy evaporating.
