产品详细介绍仪器仪表厂家直销:蛇形脂肪抽出器
产品说明:
蛇形脂肪抽出器是由提取瓶、提取管、冷凝器三部分组成的,提取管两侧分别有虹吸管和连接管, 各部分连接处要严密不能漏气。从固体物质中萃取化合物的一种方法是, 用溶剂将固体长期浸润而将所需要的物质浸出来,即长期浸出法。此法花费时间长。 溶剂用量大、效率不高。
主要特点:
蛇形脂肪抽出器是利用溶剂回流及虹吸原理,使固体物质连续不断地被纯溶剂萃取, 既节约溶利萃取效率又高。萃取前先将固体物质研碎,以增加固液接触的面积。 然后,将固体物质放在滤纸套内,置于提取器中,提取器的下端与盛有溶剂的圆底烧瓶相连, 上面接回流冷凝管。加热圆底烧瓶,使溶剂沸腾,蒸气通过提取器的支管上升, 被冷凝后滴入提取器中,溶剂和固体接触进行萃取,当溶剂面超过虹吸管的最高处时, 含有萃取物的溶剂虹吸回烧瓶,因而萃取出一部分物质,使固体物质不断为纯的溶剂所萃取、 将萃取出的物质富集在烧瓶中。液固萃取是利用溶剂对固体混合物中所需成分的溶解度大, 对杂质的溶解度小来达到提取分离的目的。 Main features: The serpentine fat extractor is to use solvent reflux and siphon principle, so that the solid material continuously is extracted by pure solvent, which can save the extraction efficiency and high efficiency. The solid material was crushed before extraction to increase the area of solid liquid contact. Then, the solid material is placed in the filter paper sleeve, and in the ext ractor, the lower end of the extractor is connected with a round bottom flask with solvent, which is connected to the reflux condenser tube. Heating round bottom flask, the solvent boiling, steam by rising branch pipe extractor, after condensation drops into the extractor solvent for extraction, and solid contact when solvent side more than the highest point of siphon, contains extract solvent siphoned back into the flask, and extract the part of the material, the solid material continuously to pure by solvent extraction, to extract the substance concentration in a flask. Liquid-solid extraction is the solubility of the solvent to the solid mixture and the solubility of impurities to extract the separation 联系人:陈余莉 联系电话:15900817434 QQ:2851513080 经营原则:严谨的技术创新追求、无微不至地服务于客户, 为客户提供最优品质的产品! 我们讲信用,重质量,生产灵活,供货时间准,是您产品配套的好选择, 真诚欢迎客户批量生产、来料加工、来图来样定做或来人来电咨询,洽谈业务! |
