M'magawo a kafukufuku wa faifarasicals ndi kafukufuku wasayansi, kuchotsedwa kwa chosungunulira ndi zinthu zakuthupi ndizofunikira njira zoyesera m'njira zoyeserera komanso zopanga. Njira Zachikhalidwe monga Entration ndi centrifugation nthawi zambiri nthawi zambiri zimakhala zowawa chifukwa chosagwirizana, kutayika kwa zosakwanira, komanso kuchotsedwa kosakwanira. Labotale freezers owuma, ndi maubwino awo apadera a kutentha kochepa komanso kupsinjika kochepa, zidatuluka ngati zida zothandiza kwambiri njirazi. Mwa iwo,"Onse" owumaali patsogolo popititsa patsogolo ukadaulo uwu.
Sayansi Yotsika Kwambiri - Kuwuma Kwambiri: Kutentha Kwambiri-kutentha
A labotale freezekukwaniritsa kuchotsedwa ndi kuchotsa kwa zinthu zomwe zili ndi magawo atatu:
Gawo lozizira:Zinthu zomwe zili ndi ma sol solt zimazizira kwambiri kutentha kuyambira -40 ° C mpaka -80 ° C, ndikupanga makhiristo oundana olimba olimba.
Kuyanika (kutumizidwa):Pansi pa chilengedwe cha vacuum (nthawi zambiri pansi pa 10Pa), makristal a Ice amagonjera mu nthunzi yamadzi, ndikuchotsa 90% ya zosungunulira.
Kuwuma kwachiwiri (decorption):Kutentha kofawirira kuwonjezeka (20-40 ° C) kumathandizira kutsikira kwathunthu kwamadzi omangidwa, zomwe zimapangitsa kuti chinyontho chomaliza cha 1% -5%.
Kuchita izi kumathetsa kuwonongeka kwa kutentha kwambiri kwa zinthu zotsekemera, kusungira kapangidwe ka mapuloteni, ma enzymes, ndi mavitamini. Kuphatikiza apo, zimapanga kapangidwe kake kamene kamakamachitidwe osavuta kapena kugwiritsa ntchito mwachindunji.
Ubwino Wofunika wa Lwinja
Poyerekeza ndi zida zamakono-zolimbitsa thupi, zowuma za laborator freeze zimapereka mwayi wapamwamba komanso makonzedwe a batch:
Kuwongolera kutentha:"Onse" a Freeze WoulukaZlgj-12Mwachitsanzo, amagwiritsa ntchito ukadaulo wozizira wozizira, kufikira kutentha kwa msampha wotsika ngati -80° C kuti muwonetsetse msanga.
Wogwirizira wanzeru kwambiri:Zovuta kwambiri mosalekeza kuwunikira zowunikira (≤5pa), ndi njira zotetezedwa kuti mupewe kusungunula.
Kutentha Kwambiri Kwa Kudalirana:Okonzeka ndi ma fomu owombera alumu (monga "onse" a "onse" a Freeze Stor Control Technology), makina awa amalola kutentha kutentha kwa zinthu zosiyanasiyana, kukhathamiritsa kukhazikika.
Mwachitsanzo. Mosiyana ndi zimenezo, kuyanika-kuyanika pa kutentha kochepa kwa 95% ya antibods, omwe ali ndi ufa kukhala wokhazikika posungira nthawi yayitali.
Monga kampani yolumikizira zida zowuma zakunyumba kwa zaka 17, "onse awiri" atulutsidwe a Freeze adachulukitsa kuchotsedwa kwa ntchito yopitilira muyeso.
1. Njira Yomaliza Yapamwamba
Wowuma wa "onse" a Labotary Freezer amakhala ndi mtundu wa handscreen ndi gawo losungirako deta (wokhoza kusunga zolemba 100,000). Imapereka ma cuver enieni okwera, omwe amathandizira ofufuza kuti adziwe mathero a sungunulira, kupewa kuyanika kapena kuchepetsa nkhawa kapena zotsalira.
2. Njira zotetezera zingapo
Zovala Zowonekera Pampout Ngati kutentha kwa msampha kuli pamwamba -50 ° C kuti tilepheretse kuwonongeka kwa ndalama.
Zomveka ndi ma alarm a ma alarm omwe ali ndi zoyeserera zokhazokha pofuna kulephera kapena kusinthasintha kutentha.
Kusankha kwamphamvu kwa magetsi kumasunga dongosolo lowongolera kwa mphindi 20 panthawi yotuluka, onetsetsani kuyesa kupitiliza.
3.. Mobwerezabwereza ntchito
Ndi njira yosankhira yosankha makina osokoneza bongo, mpweya wambiri monga nayitrogeni ukhoza kuyambitsa chipinda chowuma kuti aletse mafuta omwe amasungunuka (mwachitsanzo, ethanol). Kachipindacho, chopangidwa kuchokera ku ukhondo wosakhazikika ndi kapangidwe kake ka msangwe chopanda coil, chimachotsa zoopsa zodutsa.
Laborator Freezer Omwe wasintha chifukwa cha zida zosavuta zaphokoso kwambiri pamasewera owongolera. "Onse"Zlgjmndandanda, kudzera mwanzeru komanso mwamphamvu, osati zimangosintha zosungunulira bwino komanso zimathandizira kuwunikira zenizeni ndi kukhathamiritsa kwa ntchito yochokera pansi. Kwa ofufuza omwe amayang'ana kuwunika ndi zotsatira zokhazikika, zida izi zikuyamba "machitidwe ofunikira" mu labotale.
