磁力攪拌器操作簡便，無級(jí)調(diào)速，能在較廣的速度范圍內(nèi)對(duì)液體溶液進(jìn)行精密穩(wěn)定的攪拌，特別適合小體積樣品的試驗(yàn)。磁力攪拌器可以分為不加熱型、加熱型、恒溫型三類，有的機(jī)型增設(shè)了雙向、多頭攪拌功能。它是現(xiàn)代石油、化工、醫(yī)藥衛(wèi)生、環(huán)保、生化、實(shí)驗(yàn)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.
