產(chǎn)品詳細(xì)介紹儀器儀表廠家直銷(xiāo):蛇形脂肪抽出器
產(chǎn)品說(shuō)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(cè)分別有虹吸管和連接管, 各部分連接處要嚴(yán)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(zhǎng)期浸潤(rùn)而將所需要的物質(zhì)浸出來(lái),即長(zhǎng)期浸出法。此法花費(fèi)時(shí)間長(zhǎng)。 溶劑用量大、效率不高。
主要特點(diǎn):
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(guò)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(jìn)行萃取,當(dāng)溶劑面超過(guò)虹吸管的最高處時(shí), 含有萃取物的溶劑虹吸回?zé)浚蚨腿〕鲆徊糠治镔|(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(duì)固體混合物中所需成分的溶解度大, 對(duì)雜質(zhì)的溶解度小來(lái)達(dá)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(yíng)原則:嚴(yán)謹(jǐn)?shù)募夹g(shù)創(chuàng)新追求、無(wú)微不至地服務(wù)于客戶(hù), 為客戶(hù)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(shí)間準(zhǔn),是您產(chǎn)品配套的好選擇, 真誠(chéng)歡迎客戶(hù)批量生產(chǎn)、來(lái)料加工、來(lái)圖來(lái)樣定做或來(lái)人來(lái)電咨詢(xún),洽談業(yè)務(wù)! |
