Ti freezer ta ultra-low temperature (ULT) ati laveki ngopfu eka ti laboratory, ti biorepositories, na swibedlhele swa ndzavisiso. Ti tlanga xiave xa nkoka swinene eka ku hlayisa vutomi bya xelufu bya swikombiso swa biological swofana na ti enzymes, tissues, bacteria, na switlhavelo. Ti freezers leti tinyika vulawuri bya mahiselo lebyi kongomeke naku tshembheka kutlula ti freezers leti tolovelekeke, leti hlayisaka mahiselo yale hansi swinene, hi ntolovelo exikarhi ka -50°C na -86°C. Ti freezer ta ULT i ta nkoka eka sayense ya vutomi na tinsimu ta ndzavisiso wa tliliniki, kambe ti lava ku hlayisiwa hi vukheta leswaku ti tirha kahle. Ku kuma vuxokoxoko byo tala hi Ultra Low Freezer , kambisisa nkongomiso wa hina lowu heleleke.
Ku hlawula Freezer ya Ultra-Low Temperature leyinene
Loko u hlawula freezer ya ULT, swipimelo leswi u kongomisaka eka swona swita ya hi swilaveko swaku hlayisa tisampulu ta wena hiku hlayiseka. Vukulu bya freezer byi lawuriwa hi vuhlayiselo lebyi u byi lavaka na ndzhawu leyi kumekaka eka ndzhawu ya wena. Ti freezer ta ULT leti yimisiweke hi ntolovelo ti pfumelela vuhlayiselo byotala handle ko teka ndzhawu yotala yale hansi. Loko unga kunguhati ku hlayisa nhlayo leyikulu ya swikombiso kumbe unga tirhi na swikombiso leswikulu, ti freezer letintsongo tinga tirhela xikongomelo xa wena hindlela leyinene.
Nhlayo ya mahiselo i nchumu wun’wana wa nkoka eka ku hlawula freezer ya ULT. Ku hlawula ka wena kufanele kuya hi tinxaka ta tisampulu leti u kunguhataka ku ti hlayisa, tani hileswi tisampulu tin’wana ti lavaka hambi kuri mahiselo yale hansi kutlula tin’wana. Ti freezer ta Stirling Ultracold ULT tinyika mahiselo yo anama swinene lawa ya tirhisiwaka hiku seketela ti setpoints leti tiyeke exikarhi ka -20°C na -86°C.
Maendlelo Lamanene ya Vulawuri bya Ultra-Low Temperature Freezer
Ku lawula kahle freezer ya ULT i xilotlelo xo kurisa vutomi bya yona na vukorhokeri bya yona. Hiku tshama emahlweni ka mintlhontlho leyi fambelanaka na freezer ya ULT, unga tiyisisa leswaku yi vekiwile naku hlayisiwa kahle leswaku yita tirha kahle xikan’we naku tirha kahle.
Anakanya hi Ku Vekiwa ka Freezer na Swilaveko swa Switirhisiwa
Yin’wana ya magoza ya nkoka swinene loko u xava freezer ya ULT i ku tiyisisa leswaku ndzhawu ya ndzhawu yi hlomisiwile kahle ku khoma freezer leyikulu, ya matimba yale henhla. Ku hlayisa mahiselo yale hansi swinene swilava matimba swinene. Tiyisisa leswaku xihlovo xa wena xa gezi lexi kunguhatiweke xi nyika voltage leyi eneleke na leyi faneleke eka modele wa freezer leyi hlawuriweke naswona a yi nge rhwali ngopfu hi switirhisiwa swo tala swa matimba ya le henhla. Timodelo tin’wana ta ULT, kufana na tiyuniti ta Stirling, tinga tirha eka ti voltage to tala, ku papalata ku hlanganisiwa ka tintambhu ta switirhisiwa na ku olovisa ku fambisana na swilaveko swohambana hambana swa gezi emisaveni hinkwayo. Matimba ya backup yatala ku laveka kuva ku papalatiwa ku lahlekeriwa hi nhundzu ya nkoka swinene naswona minkarhi yin’wana leyinga cinciwiki ya biological leyi hlayisiweke eka ti freezers ta ULT.
Ti freezer ta ULT tinga tlhela ti humesa kuhisa lokukulu, leswivulaka leswaku kuva na ti freezer totala eka ndzhawu yin’we swinga endla leswaku ku titimela switika swinene. Vunyingi bya ti model ta ULT freezer tifanele ku tirha eka ndzhawu ya mahiselo ya ndzhawu leyinga hundziki 32°C, hambi leswi ti model ta Stirling tinga tirhisiwaka hiku hlayiseka eka mahiselo ya ndzhawu yale henhla ka 35°C. Ndzhawu leyi ringaneleke ya freezer yi pfumelela ku khuluka ka moya ku rhendzela yona xikan’we naku nghena ka moya, leswinga swa nkoka swinene leswaku yita tirha kahle. Ti freezer leti tiyisisiweke hi ENERGY STAR® ta pfuna tani hileswi ti humesaka kuhisa kutsongo naswona tinga hunguta swilaveko swa HVAC.
Vuswikoti bya Freezer byo Hlayisa Switirhisiwa
Ti freezers ta ultra-low ti tirha kahle loko moya wo titimela endzeni wunga kavanyetiwi naswona ndzhawu yo hlayisa yi kurisiwa swinene. Switirhisiwa swa xikombiso swifanele ku lulamisiwa kahle no lawuriwa eka freezer ku olovisa ku vuyisa naku tiyisisa nkarhi wo koma swinene leswaku nyangwa wutshama wu pfulekile. Mphakelo wa laboratory na switirhisiwa aswifanelanga ku hlengeletiwa ehenhla ka freezer, leswinga khoma moya wo kufumela, leswi endlaka leswaku ku tirha kahle ka freezer kuhunguteka hiku famba ka nkarhi.
Ku Langutisisa Mahiselo na Swilo swa Data
Ti ULT totala tina sisiteme yo langutisisa mahiselo leyi akiweke endzeni, kukatsa na ti alamu tale henhla nale hansi xikan’we na ti data loggers. Tisisiteme to veka tihlo ta le kule na leti simekiweke eka mapapa ti nga ku lemukisa hi riqingho kumbe imeyili loko mahiselo ya khabinete ya ri ehenhla swinene na ku ku tivisa loko ku vuyiseriwa ka mahiselo swi laveka leswaku u ta kota ku teka goza hi ku hatlisa. Switlhela swikoteka ku ndlandlamuxa eka tisisiteme ta xiyimo xale henhla swinene leti katsaka ku kufumela ka backup na ti alarm ta mahiselo ya ndzhawu.
Ku Endla Vuhlayiseki bya Nkarhi na Nkarhi
Kufana na switirhisiwa swihi na swihi swa lab, ku endla vuhlayiseki byo sivela swi famba ndlela yo leha eka ku hlayisa switirhisiwa na ku tiyisisa leswaku swiya emahlweni switirha hindlela ya kahle. Mintirho yo hlayisa yi katsa ku basisa nkarhi na nkarhi na ku cinca xisefo xa condenser, ku tshamela ku susa xirhami eka freezer, na ku kalibhara freezer ya wena nkarhi na nkarhi.
Hlantswa Yuniti ya Wena Nkarhi na Nkarhi
Eka tiyuniti leti tirhisaka compressor, ntshuri wutala ku hlengeletana eka condenser. Ku basisa condenser filter switiyisisa leswaku freezer yinga kufumeta kahle tisampulu. Unga hirha service yo basisa filter, kutani unga vacuum ku rhendzela ti condenser coils hi wexe kutani u susa naku hlamba filter.
De-icing na Defrosting ya Freezer ya Wena
Ku tshamela ku defrosting/de-icing freezer na swona i xilotlelo xa leswaku freezer ya wena ya ULT yi tirha kahle. Ku hlengeletana ka ayisi efrijini swi nga onha tinyangwa ta le ndzeni, swi endla leswaku xitirhisiwa xi hisa ngopfu naswona swi veka swikombiso swa wena swa nkoka ekhombyeni. Ufanele ku susa ayisi eka freezer tani hileswi swilaveka naswona u pulana ku susa ayisi eka freezer kan’we kuya eka kambirhi hi lembe.
Kalibrate Freezer Ya Wena
Ku tirhisiwa loku yaka emahlweni swinga endla leswaku sisiteme yo veka tihlo ya freezer na ti probes swinga kongomanga ngopfu. Freezer yifanele ku kalibiwa nkarhi na nkarhi tani hileswi standard operating procedure (SOP) yi kombisaka, kambe hi ntolovelo kan’we hi lembe swiringanerile.
Mahetelelo
Ti freezer ta mahiselo yale hansi swinene tina nkoka swinene eka ku hlayisa switirhisiwa swa biological eka ndzavisiso na swikongomelo swa tliliniki. Ku hlawuriwa kahle, ku vekiwa na ku hlayisiwa ka ti freezer leti switiyisisa leswaku ti tirha kahle xikan’we naku hanya nkarhi woleha. Hiku landzelela maendlelo ya kahle eka vulawuri bya ti freezer ta ULT, ti laboratory tinga hlayisa tisampulu ta tona ta nkoka naku hlayisa vutshembeki bya ndzavisiso wa tona. Ku kuma vuxokoxoko byo tala hi Ultra Low Freezer , endzela xitirhisiwa xa hina xa vuxokoxoko.
