Ukubanda kuyindlela yokulondoloza ukudla, izidakamizwa, nezinye izinto ngokwehlisa izinga lokushisa libe ngaphansi kwezinga lokubanda.Lobu buchwepheshe bunganweba ngempumelelo impilo yeshalofu yemikhiqizo, njengoba amazinga okushisa aphansi ehlisa kakhulu ukukhula kwama-microorganisms kanye nesivinini sokuphendula kwamakhemikhali.Okulandelayo ulwazi oluningiliziwe mayelana nokuqandisa:
Izimiso Eziyisisekelo
1. Ibanga lokushisa: Ukubanda ngokuvamile kuhilela ukwehlisa izinga lokushisa lomkhiqizo liye ku -18 ° C noma ngaphansi.Kuleli zinga lokushisa, amanzi amaningi enza amakristalu eqhwa, umsebenzi we-microbial uyama, futhi inqubo ye-metabolic yokudla nayo iyancipha kakhulu.
2. Ukuguqulwa kwamanzi: Phakathi nenqubo yokubanda, amanzi emkhiqizweni aguqulwa abe amakristalu eqhwa, okusiza ukuvimbela ukukhula kwamagciwane kanye nokusabela kwamakhemikhali ukuthi kwenzeke.Kodwa-ke, ukwakheka kwamakristalu eqhwa kungase kuphazamise ukwakheka kwamangqamuzana, okungesinye sezizathu zokuthi kungani ukudla okuqandisiwe kungase kube nezinguquko zokuthungwa ngemva kokuncibilika.
Ubuchwepheshe bokuqandisa
1. Ukubanda okusheshayo: Ukuqhwaza okusheshayo kuyindlela evame ukusetshenziswa enciphisa usayizi wamakristalu eqhwa akhiwa ngaphakathi kokudla ngokwehlisa ngokushesha izinga lokushisa lokudla, okusiza ukuvikela ukwakheka nokuthungwa kokudla.Lokhu kuvame ukufezwa ekukhiqizweni kwezentengiselwano kusetshenziswa imishini esebenza kahle yesiqandisi.
2. Izinga lokushisa eliphansi kakhulu lokuqandisa: Kwezinye izinhlelo zokusebenza ezithile (ezifana nezinkambu ezithile zocwaningo lwesayensi nokugcinwa kokudla okusezingeni eliphezulu), iqhwa eliphansi kakhulu lingase lisetshenziswe, futhi izinga lokushisa lingancishiswa libe -80 ° C noma lehle ukuze kufinyelelwe. isikhathi eside kakhulu sokulondoloza.
3. Isitoreji esiqandisiwe: Ukudla okuqandisiwe kudinga ukugcinwa endaweni efanele yesiqandisi, njengesiqandisi sasekhaya noma indawo yokugcina izinto ezibandayo, ukuze kuqinisekiswe ukuthi ukudla kugcinwa endaweni ephephile ngokuqhubekayo.
indawo yesicelo
1. Imboni yokudla: Embonini yokudla, ukuqandisa kuyindlela evamile yokulondoloza, efaneleka ukudla okuhlukahlukene njengenyama, izilwane zasolwandle, ukudla okuphekiwe, imikhiqizo yobisi, izithelo nemifino.
2. Ukunakekelwa kwezempilo: Imithi ethile namasampula ebhayoloji (njengegazi, amaseli, njll.) adinga i-cryopreservation ukuze agcine ukuqina nokusebenza kwawo.
3. Ucwaningo lwesayensi: Ocwaningweni lwesayensi, ubuchwepheshe bokuqandisa busetshenziselwa ukulondoloza amasampula emvelo ahlukahlukene kanye nama-reagents amakhemikhali ukuze kwenziwe ucwaningo lwesikhathi eside nokuhlaziya.
izindaba ezidinga ukunakwa
1. Ukupakisha ngendlela efanele: Ukupakisha ngendlela efanele kubalulekile ukuze kuvinjelwe isithwathwa kanye nokomisa kokudla.Ukusebenzisa izinto zokupakisha ezivikela umswakama futhi ezivalwe kahle kungavikela ukudla.
2. Gwema imijikelezo yokuqhwaza ephindaphindiwe: Imijikelezo yokuqhwaza ephindaphindiwe ingalimaza ukuthungwa nokondleka kokudla, futhi kufanele kugwenywe ngangokunokwenzeka.
3. Ukuncibilika okuphephile: Inqubo yokuncibilika nayo ibaluleke kakhulu, futhi kufanele incibilike kancane kancane esiqandisini, noma incibilikiswe ngokushesha kusetshenziswa i-microwave namanzi abandayo ukuze kuncishiswe ithuba lokukhula kwamagciwane.
Ukuqandisa kuyindlela yokulondoloza ephumelela kakhulu ebambezela kakhulu ukusebenza kwamagciwane kanye nezinguquko zamakhemikhali, okunweba isikhathi seshelufu sokudla nezinye izinto ezibucayi.Izindlela ezilungile zokuqanda nokuncibilikisa zingakhuphula izinga lokudla okunomsoco kanye nezinzwa.
