一种多用途实验瓶
:本技术涉及实验分析领域,具体为用于实验室液前处理分析设备,涉及一种多用途实验瓶。
技术介绍
:在实验室化学分析中,液固萃取和液液萃取是最为普遍的从样品中提取目标成分的两种前处理方式,这两种前处理方式通常都包括提取、过滤、分液、净化、浓缩、定容等一种或多种实验步骤。目前这些实验步骤用到的实验器皿都是不同的,用于液固萃取的实验器皿有索氏提取器、锥形瓶、三角瓶等,液液萃取则通常为分液漏斗、离心管、烧杯等。液固萃取完毕后一般用滤纸置于玻璃漏斗上或布氏漏斗进行过滤。液液萃取则需要多次用分液漏斗振摇提取然后静置分层,去除废液。等提取完毕后大多数实验还需要用到层析柱进行固相萃取净化处理,收集滤液或洗脱液于浓缩瓶进行浓缩,浓缩过后用容量瓶来定容。从以上实验流程可知,整个前处理过程用到的玻璃器皿非常多,需要从这一种玻璃器皿转移到另一种玻璃器皿,工作量大,效率低。而且在转移器皿的过程中容易因为器皿的不洁净而发生沾染,或者容易因为操作不当发生目标物损失或交叉污染。由此,开发出一种可以同时用于提取、过滤、分液、净化、浓缩、定容等多种实验操作步骤的实验器皿非常必 ...
