Emikhakheni yezokwelapha ngemithi kanye nocwaningo lwesayensi, ukususwa kwe-solvent kanye nokuhlushwa kwezinto kuyizinyathelo ezibalulekile kokubili ezinqubweni zokuhlola kanye nezokukhiqiza. Izindlela zendabuko ezifana nokuhwamuka kanye ne-centrifugation zivame ukuba nezinkinga zokungasebenzi kahle, ukulahleka kwezithako ezisebenzayo, kanye nokususwa kwe-solvent okungaphelele. Ama-dryer e-laboratory, anezinzuzo zawo ezihlukile zokushisa okuphansi kanye nokucindezela okuphansi, avele njengamathuluzi asebenza kahle kakhulu kulezi zinqubo. Phakathi kwawo,"ZOMBILI" iziqandisi zokomisaziphambili ekuthuthukiseni lobu buchwepheshe.
Isayensi Ebangela Ukomisa Okuqandisiwe: Ukuphelelwa Amanzi Emazingeni Okushisa Aphansi
A umshini wokomisa iqhwa elebhuifinyelela ekususweni kwe-solvent kanye nokuhlushwa kwezinto ngezigaba ezintathu ezibalulekile:
Isigaba Sokuqandisa Ngaphambi Kokuqandisa:Izinto eziqukethe izinyibilikisi ziqandiswa ngokushesha emazingeni okushisa asukela ku--40°C kuya ku--80°C, zakha amakristalu eqhwa aqinile.
Ukomisa Okuyinhloko (Ukususwa Kwezingqimba):Ngaphansi kwendawo yokuhlanza (ngokuvamile engaphansi kwe-10Pa), amakristalu eqhwa acwilisa ngqo emhwameni wamanzi, asuse ngaphezu kwe-90% yesinyibilikisi.
Ukomisa Kwesibili (Ukumunca):Ukwenyuka kwezinga lokushisa elincane (20-40°C) kwenza kube lula ukumuncwa ngokuphelele kwamanzi aboshwe, okuholela ekujuleni komswakama okungu-1%-5%.
Le nqubo iqeda umonakalo oshisa kakhulu ezintweni ezizwela ukushisa, ilondoloze isakhiwo sama-molecule amaprotheni, ama-enzyme, namavithamini. Ngaphezu kwalokho, idala isakhiwo esinezimbobo esenza kube lula ukubuyisela amanzi emzimbeni noma ukusetshenziswa ngqo.
Izinzuzo Eziyinhloko Zokomisa I-Laboratory Freeze
Uma kuqhathaniswa nemishini yezimboni, ama-dryer omiswe elabhorethri anikeza ukulawula okunembile okuphezulu kanye nezinzuzo zokucubungula ezincane:
Ukulawula Izinga Lokushisa Elinembile:Imodeli yomshini wokomisa oqandisiwe "YOMIBILI"I-ZLGJ-12isibonelo, isebenzisa ubuchwepheshe bokupholisa be-compressor obungenisiwe, obufinyelela amazinga okushisa aphansi njenge-80°C ukuqinisekisa ukuthi kubanda ngokushesha.
Ukuphathwa Komshini Wokuhlanza Ohlakaniphile:Izinzwa ezinembile kakhulu ziqapha amazinga e-vacuum (≤5Pa), ngezindlela zokuvikela ezakhelwe ngaphakathi ukuvimbela ukugcinwa kwe-solvent.
Ukushisa kwe-Gradient ukuze kugxilwe:Ifakwe ngokushisa kweshalofu okulungisekayo (njengobuchwepheshe bokulawula i-PLD "yokuqandisa" okomisa iqhwa), lezi zinhlelo zivumela ama-curve okushisa aklanyelwe izinto ezahlukene, okwenza kube ngcono ukuhlushwa.
Isibonelo, ocwaningweni lwelabhorethri yezinto eziphilayo oluhilela ukomisa ama-antibody ngeqhwa, izindlela zendabuko zokuhwamuka zaholela ekuhlanganisweni kwama-protein kanye nokuvala ukusebenza kwawo. Ngokuphambene nalokho, ukomisa ngeqhwa emazingeni okushisa aphansi kugcine umsebenzi we-antibody ongaphezu kuka-95%, kanti i-powder ephumelayo izinzile kakhulu ukuze igcinwe isikhathi eside.
Njengenkampani egxile emishinini yokomisa iqhwa yasekhaya iminyaka engu-17, ama-dryer "AMABILI" aqandisiwe athuthukise ukusebenza kahle kokususa izinyibilikisi ngokusungula izinto ezintsha zobuchwepheshe okuqhubekayo.
1. Uhlelo Lokulandelela Idatha Olusebenza Ngokugcwele
I-"BOBABILI" yomshini wokomisa iqhwa welabhorethri ifakwe isikrini sokuthinta sombala kanye nemojuli yokugcina idatha (ekwazi ukugcina amarekhodi afinyelela ku-100,000). Ihlinzeka ngama-curve okushisa-i-vacuum wesikhathi sangempela, okuvumela abacwaningi ukuthi banqume ngokunembile indawo yokugcina i-solvent sublimation, ukuvimbela ukoma ngokweqile noma izinkinga ze-solvent ezisele.
2. Izindlela Zokuvikela Ukuphepha Eziningi
Ukukhiya kwephampu ye-vacuum cleaner okuzenzakalelayo uma izinga lokushisa lesicupho lingaphezu kuka-50°C ukuvimbela umonakalo wokubuyela emuva.
Ama-alamu omsindo nokukhanya asebenza ngokuvikela okuzenzakalelayo uma kwenzeka ukungasebenzi kahle kwe-vacuum noma ukushintshashintsha kwezinga lokushisa okungavamile.
Ukunikezwa kwamandla okuzikhethela kwe-UPS kugcina ukusebenza kohlelo lokulawula imizuzu engama-20 ngesikhathi sokucima kukagesi, okuqinisekisa ukuqhubeka kokuhlolwa.
3. Ukwandiswa Komsebenzi We-Modular
Ngohlelo lokujova igesi oluzenzakalelayo lokucindezela kabusha, amagesi angasebenzi njenge-nitrogen angafakwa ekamelweni lokomisa ukuze kuvinjelwe ukusabela kwe-oxidation ngesikhathi sokuhlushwa kwezinyibilikisi ezizwela umoya-mpilo (isb., i-ethanol). Igumbi, elenziwe ngensimbi engagqwali ehlanzekile enomklamo wesicupho ongenama-coil, lisusa izingozi zokungcoliswa okuwela.
Ama-dryer omisa elabhorethri ashintshe kusukela kumadivayisi alula okukhipha amanzi emzimbeni aba amapulatifomu okulawula izinqubo ayinkimbinkimbi.I-ZLGJuchungechunge, ngomklamo wayo ohlakaniphile nowe-modular, ayithuthukisi nje kuphela ukusebenza kahle kokususwa kwe-solvent kodwa futhi ivumela ukuqapha kanye nokwenza ngcono inqubo yokuhlushwa ngesikhathi sangempela. Kubacwaningi ababeka phambili ukunemba kokuhlola kanye nemiphumela ezinzile, la madivayisi aba "umsizi wenqubo ejwayelekile" obalulekile emalabhorethri.
