Liquid nitrogen matangi anoshandiswa zvakanyanya midziyo yekuchengetedza muminda yebiomedicine, sainzi yezvekurima, uye indasitiri.Aya matangi anogona kushandiswa kuburikidza nenzira mbiri: vapor chikamu chekuchengetedza uye mvura chikamu chekuchengetedza, imwe neimwe iine yakasarudzika mabhenefiti uye yakashata.
I. Zvakanakira nekuipira kwe mhute chikamu chekuchengetedza mumatangi enitrogen emvura:
Vapor phase kuchengetedza inosanganisira kushandura mvura nitrogen kuita gasius state yakachengetwa mukati metangi.
Zvakanakira:
a.Kurerukira: Vapor chikamu chekuchengetedza chinobvisa kushushikana nezve evaporation uye tembiricha kutonga kwemvura nitrogen, zvichiita kuti kushanda kuve nyore uye nyore.
b.Chengetedzo: Sezvo nitrogen yemvura iri munzvimbo ine gasi, njodzi yekudonha kwemvura inoderedzwa, ichiwedzera kuchengetedzeka.
c.Versatility: Vapor phase storage inokodzera kuchengetedza nhamba huru yemasampuli, senge biological samples nembeu dzekurima.
Zvakaipa:
a.Kurasika kweEvaporation: Nekuda kwekukwira kwemvura zhinji yenitrogen, kuchengetwa kwemhute kwenguva refu kunogona kukonzera kurasikirwa nenitrogen, zvichiwedzera mutengo wekushandisa.
b.Nguva shoma yekuchengetedza: Kana ichienzaniswa neyekuchengetera chikamu chemvura, vapor chikamu chekuchengetedza chine ipfupi sampuli yekuchengetedza nguva.
II.Zvakanakira uye zvakaipira zvemvura chikamu chekuchengetedza mune yemvura nitrogen matangi:
Liquid chikamu chekuchengetedza chinosanganisira kuchengetedza zvakananga mvura nitrogen mutangi.
Zvakanakira:
a.High-density kuchengetedza: Liquid phase yekuchengetera inogona kuchengeta vhoriyamu hombe yenitrogen yemvura munzvimbo diki, ichiwedzera kuwanda kwekuchengetedza.
b.Kuchengetedza kwenguva refu: Kana ichienzaniswa nekuchengeterwa kwemhepo, chikamu chemvura chekuchengetedza chinogona kuchengetedza masampuli kwenguva yakareba, kuderedza kurasikirwa kwesample.
c.Mutengo wakaderera wekuchengetera: Liquid chikamu chekuchengetedza chiri kudhura-chinoshanda zvichienzaniswa nevapor chikamu chekuchengetedza.
Zvakaipa:
a.Kudzora tembiricha: Kudzora tembiricha kwakasimba kunodiwa kuchengetedza chikamu chemvura kudzivirira kubuda kwakanyanyisa uye kutonhora kwesampu.
b.Njodzi dzekuchengetedza: Kuchengetedzwa kwemvura kunosanganisira kusangana kwakananga nenitrogen yemvura, ichiisa njodzi dzekudonha kwenitrogen nekupisa, zvinoda kutariswa zvakanyanya kune nzira dzekuchengetedza.
III.Zvishandiso zvechikamu chemvura uye vapor chikamu chekuchengetedza:
Liquid chikamu uye vapor chikamu chekuchengetedza zvinoshandisa zvinangwa zvakasiyana mumashandisirwo akasiyana.
Zvishandiso zvechikamu chemvura chekuchengetedza:
a.Biomedicine: Liquid chikamu chekuchengetedza chinoshandiswa zvakanyanya mubiomedicine kuchengetedza biological samples, masero, matishu, nezvimwewo, zvichitsigira tsvakiridzo yekurapa uye diagnostics.
b.Agricultural biology: Masayendisiti ezvekurima anoshandisa gadziriro yemvura kuchengetedza mbeu dzakakosha, mukume, uye mazai akaomeswa nechando, kuchengetedza zvirimwa zvemajini uye kuvandudza marudzi.
c.Chengetedzo yekudzivirira: Kuchengetera kwemvura inzira yakajairika yekuchengetedza majekiseni, kuve nechokwadi chekugadzikana uye kushanda kwawo kwenguva refu.
d.Biotechnology: Mubiotechnology, yemvura chikamu chekuchengetedza chinoshandiswa kuchengetedza majini mabhangi, ma enzymes, masoja ekudzivirira chirwere, uye zvimwe zvakakosha biological reagents.
Zvishandiso zve vapor phase kuchengetedza:
a.Masero etsika marabhoritari: Mumasero tsika marabhoritari, mhute chikamu chekuchengetedza chakakodzera kuchengetedza kwenguva pfupi kwemaseru mitsara uye sero tsika.
b.Chekuchengetedza sampuli kwenguva pfupi: Kwemasamples echinguvana kana ayo asingade kuchengetedzwa kwenguva refu, vapor chikamu chekuchengetedza chinopa nekukurumidza uye nyore kuchengetedza mhinduro.
c.Miedzo ine yakaderera firiji zvinodiwa: Pakuyedza ine zvishoma kuomesesa zvinodiwa zvefiriji, vapor chikamu chekuchengetedza isarudzo ine hupfumi.
Liquid nitrogen matangi ane mhute chikamu uye mvura chikamu chekuchengetedza imwe neimwe ine zvayakanakira nezvayakaipira.Sarudzo pakati penzira dzekuchengetedza zvinoenderana neakananga mashandisirwo mamiriro uye zvinodiwa.Liquid chikamu chekuchengetedza chakakodzera kuchengetedza kwenguva refu, yakakwirira-density chengetedzo, uye mamiriro ane yakakwirira hupfumi zvinodiwa.Kune rimwe divi, vapor chikamu chekuchengetedza chiri nyore, chakakodzera kuchengetedza kwenguva pfupi uye mamiriro ane yakaderera firiji zvinodiwa.Mumashandisirwo anoshanda, kusarudza nzira yakakodzera yekuchengetedza yakavakirwa pamienzaniso hunhu uye zvidikanwi zvekuchengetedza zvinozobatsira mukuvandudza kushanda kwekushanda uye mhando yemhando.
