磁力攪拌器操作簡(jiǎn)便，無(wú)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(lèi)，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.
