磁力攪拌器操作簡便，無級調速，能在較廣的速度范圍內對液體溶液進行精密穩定的攪拌，特別適合小體積樣品的試驗。磁力攪拌器可以分為不加熱型、加熱型、恒溫型三類，有的機型增設了雙向、多頭攪拌功能。它是現代石油、化工、醫藥衛生、環保、生化、實驗分析、教育科研的*理想工具。 Magnetism Msier is operated easily,non scale changes speed,can mix liquid precisely and stably in mide speed range,especially fit little samples experiments. It is divicled into three kinds:no-heating style,heating style,constant temperture style some of which add two-way,multi head mixing function. It is necessary,ideal tools in modern oil,chemistry industry. Medical sanitation,ewironment-protecting,biochemistry,test analysis educational scientific research.
