產(chǎn)品詳細介紹儀器儀表廠家直銷:蛇形脂肪抽出器
產(chǎn)品說明:
蛇形脂肪抽出器是由提取瓶、提取管、冷凝器三部分組成的,提取管兩側分別有虹吸管和連接管, 各部分連接處要嚴密不能漏氣。從固體物質(zhì)中萃取化合物的一種方法是, 用溶劑將固體長期浸潤而將所需要的物質(zhì)浸出來,即長期浸出法。此法花費時間長。 溶劑用量大、效率不高。
主要特點:
蛇形脂肪抽出器是利用溶劑回流及虹吸原理,使固體物質(zhì)連續(xù)不斷地被純?nèi)軇┹腿。?br/>既節(jié)約溶利萃取效率又高。萃取前先將固體物質(zhì)研碎,以增加固液接觸的面積。 然后,將固體物質(zhì)放在濾紙?zhí)變?nèi),置于提取器中,提取器的下端與盛有溶劑的圓底燒瓶相連, 上面接回流冷凝管。加熱圓底燒瓶,使溶劑沸騰,蒸氣通過提取器的支管上升, 被冷凝后滴入提取器中,溶劑和固體接觸進行萃取,當溶劑面超過虹吸管的最高處時, 含有萃取物的溶劑虹吸回燒瓶,因而萃取出一部分物質(zhì),使固體物質(zhì)不斷為純的溶劑所萃取、 將萃取出的物質(zhì)富集在燒瓶中。液固萃取是利用溶劑對固體混合物中所需成分的溶解度大, 對雜質(zhì)的溶解度小來達到提取分離的目的。 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 聯(lián)系人:陳余莉 聯(lián)系電話:15900817434 QQ:2851513080 經(jīng)營原則:嚴謹?shù)募夹g創(chuàng)新追求、無微不至地服務于客戶, 為客戶提供最優(yōu)品質(zhì)的產(chǎn)品! 我們講信用,重質(zhì)量,生產(chǎn)靈活,供貨時間準,是您產(chǎn)品配套的好選擇, 真誠歡迎客戶批量生產(chǎn)、來料加工、來圖來樣定做或來人來電咨詢,洽談業(yè)務! |
