本机采用了集热式加热法，被加热溶液*处于均匀强烈的热辐射中，加热速度快，节省能源。配置优质磁钢与聚四氟搅拌子，更经久耐用，深受广大用户的好评。 It’s structure is reasonable,the chosen materials are super. It has been developed and improved by teehniciant to wholly sohe the problems about vacuum reaction of ball-flask,mixing long to press pressure stable temperature to heat. It can use water,oil,won-water to burn be divided into needle style and numerical show. It uses heat-gathering to heat,the heated liquid is involved in even and strong heat radiation, Heating speed is very suift and can save energy. Be equipped with magent steel and tetrafluoroe the leno and can be used longer,and praised highly by most users
