萃取分离是实验室进行样品成分提取,分离和浓缩的一种重要手段。萃取比色分析也是测定样品中一些微量金属元素含量的常用分析方法。实验室萃取分离工具常用分液漏斗和具塞三角烧瓶。分液漏斗用人工振摇,萃取率因人而异,差别较大。具塞三角瓶虽可用电动振荡器振摇,但振摇时不能排气,常发生瓶塞崩落现象。多用电动振荡提取器集分液漏斗、具塞三角烧瓶和抽液管为一体,发挥了三者的优点。避免了各自的弊端。如再配制一些附件,用途将更广泛。样品经一些单位试用,认为结构 Extraction and separation is the laboratory for sample components extraction, separation and concentration of an important means. Extractive colorimetric analysis is also a common analytical method for determining the trace metal content in a sample. Common laboratory separations separators and plugged Erlenmeyer flasks. Separation funnel artificial shaking, extraction rate varies from person to person, the difference is larger. Although plugged triangular flask can be shaken with an electric oscillator, but not when the shaking exhaust, cork caving often occur. Multi-purpose electric shaker extractor separations funnel, stopper conical flask and pipette as a whole, to play the advantages of the three. Avoid their own drawbacks. If you prepare some attachments, the purpose will be more extensive. Samples tested by some units, that the structure
