Description
| 玻璃三角漏斗30 40 50 60 75mm 90mm 120mm 210mm 240mm玻璃弯颈漏斗 分液漏斗 |
| 使用方法： | ||||||||||||
| 先按照分液漏斗的球体制作一个木架，将分液漏斗洗净、烘干，把分液漏斗活塞关闭，将待分离物质的液体以及溶剂注入漏斗内，注入的数量约占漏斗标称容量的60%左右，留有一定的空隙便于摇动。再将瓶塞塞紧，在两手的配合下，一只手的手心抵住瓶塞，另一只手护住漏斗活塞，上下摇动使溶液充分搅拌混合，并不时地旋开瓶塞，在旋开瓶塞时瓶塞的口不要对准自己和别人，以防气体将液体冲出，整个萃取操作需要放气4-5次，待水溶液中的物质（如叶绿素），全部移到有机溶剂后，即可静置在漏斗架上进行分层，打开活塞，把水溶液从漏斗管柄处放出，再关闭活塞，漏斗内的上层溶液由漏斗瓶颈处倾出即可。 | ||||||||||||
| 如作提取某些物质溶液时： | ||||||||||||
| 将物质倾入漏斗内中，然后加入选择性的溶剂，将瓶塞塞好，缓慢地摇动几分钟，静置若干小时，待分层明显时打开活塞，将底层液体放出，再放入新的提取剂，经过几次操作即可。 | ||||||||||||
| 作分离操作： | ||||||||||||
| 将试液放入漏斗中，然后加入分离剂，盖好瓶塞，摇动，然后将漏斗倒置，开启活塞放出气体，继续摇动，重复操作数次，静置数分钟后液体分为两层，再用活塞将其分离即可。 | ||||||||||||
| 用途： | ||||||||||||
适用于制药工业、大专院校、科研、钢铁冶金、石油化工、工矿企业、植物研究和提炼等单位用作从溶剂中提取某种成分或分离提取某种杂质用。球形、梨形、筒形等分液漏斗，也可作为在反应操作过程中添加溶液的工具。
