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

In stock
Item Number: VTS1
EQ-VTS-1 is a rotatable vacuum ampoule sealing device which is designed for helping research to seal 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 thermoelectronic materials sample and grow two dimension crystals which are sensitive to air or easy evaporating.
