Iziqandisi zezokwelapha zisetshenziswa emikhakheni yezokwelapha nezesayensi ikakhulukazi ehloselwe ukongiwa kanye nokugcinwa kwama-reagents, amasampula ebhayoloji, kanye nemithi.Njengoba umgomo wawusetshenziswa kabanzi emhlabeni wonke, uya ngokuya ubonakala.
Kukhona ezinye izici ezahlukene nezinketho ezitholakalayoiziqandisi zezokwelapha.Ngokuya ngezikhathi ezihlukene zokusebenzisa, Iningi lamayunithi akhelwe inhloso awela ezigabeni ezinhlanu:
Isitoreji Sokugoma
Izimpahla Zemithi
Ibhange Legazi
Ilabhorethri
I-Chromatography
Ukukhetha isiqandisi esifanele sezokwelapha sekubaluleka.Kunezici eziningana zokukhetha isiqandisi esifanele sezokwelapha.
Usayizi Wefriji
Ukuthola usayizi ofanele kuyisici esibalulekile enqubweni yokukhetha.Uma iyunithi yesiqandisi sezokwelapha inkulu kakhulu, kuzoba nzima ukugcina izinga lokushisa langaphakathi ngaphakathi kwebanga elishiwo.Ngakho-ke, kungcono ukubheka okuthile okuzofanelana nezidingo zokugcina.Ngakolunye uhlangothi, amayunithi amancane kakhulu ezidingweni zesitoreji angabangela ukuminyana kanye nokungagelezi kahle komoya kwangaphakathi - okungasunduzela okunye okuqukethwe ngasemaphethelweni angemuva eyunithi, futhi kwenze buthaka ukusebenza kahle kwemithi yokugoma noma amanye amasampuli ngaphakathi.
Njalo sebenzisa inani lezinto ezizogcinwa esiqandisini ngasinye sezokwelapha.Uma kungenzeka, zama ukucabangela izinguquko ezingaba khona ezidingweni zesitoreji, ukuze uzilungiselele.
Ukubekwa kwesiqandisi
Kungase kuzwakale njengokungabaza kodwa ukubekwa nakho kuyisici okufanele sicatshangelwe, ngoba ukubekwa kuzonquma ukuthi iyunithi izokwakhelwa ngaphakathi, noma izimele.
Ngesikhungo esinesikhala esincane, kunconywa ukusebenzisa amayunithi ahlangene, njengoba angangena kalula noma ngaphansi kwama-counter-tops amaningi;kuyilapho isiqandisi esikhulu nesiqondile sifaneleka kangcono endaweni yokusebenzela engadingi ukonga indawo yaphansi.Ngaphandle kwalokhu, kubalulekile futhi ukuqinisekisa ukuthi kunesikhala esanele esizungeze iyunithi ukuze kusetshenziswe umoya ofanele - cishe amayintshi amabili kuya kwamane kuzo zonke izinhlangothi.Iyunithi ingase futhi idinge ukubekwa ekamelweni elihlukile lapho ingagcinwa khona iphephile ekuchayekeni emazingeni okushisa ahlukahlukene phakathi nosuku.
Ukuvumelana Kwezinga Lokushisa
Elinye iphuzu elibalulekile elibeka isiqandisi sezokwelapha ngaphandle kwesiqandisi sasekhaya yikhono laso lokulawula izinga lokushisa elinembile.Kukhona +/-1.5°C izinga lokushisa elifanayo.Amayunithi eziqandisi zezokwelapha zakhelwe ukuqinisekisa ukuthi amasampula ezokwelapha nezinto ezisetshenziswayo zigcinwa ngaphakathi kwebanga elithile lokushisa ukuze kugcinwe ukusebenza.Sinebanga elilandelayo lokushisa elihlukile lezigaba ezahlukahlukene.
-164°C / -152°C Isiqandisi se-Cryogenic
-86°C Isiqandisi Sezinga lokushisa Eliphansi kakhulu
-40°C Isiqandisi Sezinga lokushisa Eliphansi kakhulu
-10~-25°C Isiqandisi Sezinto eziphilayo
2~8°C Isiqandisi Sekhemisi
2~8°C Isiqandisi esingaqhumisi
2~8℃ Isiqandisi Esifakwe Iqhwa
4±1°CIsiqandisi Sebhange Legazi
+4℃/+22℃ (±1) Isiqandisi Sebhange Legazi Elihambayo
Ngokwesibonelo,isiqandisi sokugomangokuvamile igcina amazinga okushisa aphakathi kuka +2°C kuya +8°C (+35.6°F kuya +46.4°F).Ukushintsha kwezinga lokushisa kungathinta amandla abo noma kucekele phansi ucwaningo oludle umzamo omkhulu kanye nemali.Ukulawulwa kwezinga lokushisa okungazinzile kungase futhi kusho ukulahlekelwa kweminikelo yegazi ezindaweni zokugcina igazi kanye nokushoda kwemithi edingekayo ezibhedlela nasemitholampilo yezokwelapha, kuyilapho izikhungo zocwaningo zingakhetha iziqandisi ezingagcina amasampula ezimeni ezishiwo ngokuqinile.Ngokuyisisekelo, iziqandisi zezokwelapha ezikhethekile zingasetshenziselwa izinjongo ezihlukene, inqobo nje uma ukusetshenziswa kwazo kuzifanele izidingo zesikhungo.
I-Digital Temperature Monitoring System
Ukungena kwezinga lokushisa kungenye ingxenye ebalulekile ekugcineni amasampula ezokwelapha kanye nemithi yokugoma ilondolozwe kahle ngaso sonke isikhathi.
I-Centers for Disease Control (CDC) iphakamisa ukuthi kuthengwe iziqandisi zezokwelapha ezinama-Temperature Monitoring Devices (TMD) kanye ne-Digital Data Loggers (DDL) okuzovumela abasebenzisi ukuthi balandelele futhi baqoqe idatha yangaphakathi lokushisa ngaphandle kokuvula umnyango.Ukuze ukuqapha izinga lokushisa kwedijithali, isistimu ye-alamu, nokugcinwa kwedatha yizici ezibalulekile eziqandisini zezokwelapha.
Ukubeka amashelufu
Wonke amayunithi ebanga lezokwelapha adinga amasistimu wokubekelwa phansi akhuthaza ukugeleza komoya okusebenzayo.Kutuswa ukukhetha iziqandisi zezokwelapha ezinamashalofu akhelwe ngaphakathi noma alungiseka kalula ukuze uqiniseke ukuthi iyunithi ingabamba inani elanele lokuhlinzekwa ngaphandle kokuminyana.Kufanele kube nesikhala esanele phakathi kwebhodlela ngalinye lomuthi wokugoma kanye nesampula yebhayoloji ukuze umoya uhambe kahle.
Iziqandisi zethu zifakwe amashalofu ekhwalithi ephezulu enziwe ngocingo lwensimbi olunamekwe nge-PVC anamakhadi omaka kanye nezimpawu zokuhlukanisa, okulula ukuzihlanza.
Uhlelo Lokuvikela:
Ezikhungweni eziningi, izinto ezibalulekile kungenzeka zigcinwe ngaphakathi kwesiqandisi sezokwelapha.Ngakho-ke kubalulekile ukuba neyunithi eza nesikhiya esivikelekile - ikhiphedi noma isihluthulelo senhlanganisela.Ngakolunye uhlangothi, kufanele ibe nesistimu ye-alamu ephelele ezwakalayo nebonakalayo, isibonelo, izinga lokushisa eliphezulu neliphansi, iphutha lenzwa, ukwehluleka kwamandla, ibhethri eliphansi, i-ajar yesicabha, iphutha lokuxhumana kwebhodi elikhulu lokushisa kwe-ambient, amasampula esaziso esiphelelwe yisikhathi, njll;Ukulibaziseka kokuqala kwe-compressor nokumisa ukuvikelwa kwesikhashana kungaqinisekisa ukusebenza okuthembekile.Kokubili isilawuli sesikrini esithintwayo nesilawuli sekhibhodi sinokuvikeleka kwephasiwedi okungavimbela noma yikuphi ukulungiswa kokusebenza ngaphandle kwemvume.
Izici ezengeziwe okufanele uzicabangele:
I-Defrost System: Isistimu yokuqeda isiqandisi yeyunithi yezokwelapha akuyona into okufanele inganakwa.Ukuqothula isiqandisi mathupha kuzobiza isikhathi, kodwa kubalulekile ezinhlelweni ezithile kanye nezidingo.Ngaphandle kwalokho, amayunithi azincibilikisa ngokuzenzakalelayo adinga ukunakekelwa okuphansi nesikhathi esincane kodwa azosebenzisa amandla amaningi kunamayunithi okwenziwa ngesandla.
Izicabha Zengilazi Nezicabha Eziqinile: Lokhu kuzoba indaba ebalulekile phakathi kokuvikeleka nokubonakala.Iziqandisi zezokwelapha ezineminyango yengilazi ziyoba usizo, ikakhulukazi ezimweni lapho umsebenzisi edinga ukubheka ngokushesha ngaphakathi ngaphandle kokukhipha noma yimuphi umoya obandayo;kuyilapho iminyango eqinile inikeza ukuvikeleka okwengeziwe.Izinqumo eziningi lapha zizoncika ohlotsheni lwesikhungo sokunakekelwa kwezempilo lapho lolu phiko luzosetshenziswa khona.
Izicabha Ezizivalayo: Imishini yeminyango ezivalayo isiza amayunithi eziqandisi zezokwelapha avimbele amazinga okushisa ukuthi angaphazamiseki njalo.
Ukunquma ukuthi yisiphi isiqandisi esizothengwa kuncike kakhulu enjongweni ehlongozwayo eyisisekelo yeyunithi.Kubalulekile futhi ukuqonda ukuthi ukukhetha imodeli akusekelwe kuphela ezidingweni zasemsebenzini kodwa nasezidingweni ezingase zibe khona esikhathini esizayo.Akukho okubi ngokulindela izimo ezizayo.Ukuze wenze ukukhetha okufanele manje, cabangela ukuthi zonke lezi zici zingase zibe khona kanjani phakathi neminyaka isiqandisi sezokwelapha esizosetshenziswa.
