Tangi rechando rezvikafu zvegungwa

Pfupiso:

Tekinoroji yekuchengetedza nitrogen yemvura yegungwa (cryopreservation) tekinoroji itsva yechando yechikafu mumakore achangopfuura. Tembiricha yakajairika yenitrogen yemvura iri -195.8 ℃, uye parizvino inozivikanwa senzvimbo inotonhodza ine hushamwari kune nharaunda, inoshanda uye isingadhuri zvakanyanya. Kana nitrogen yemvura yakabatana nehove, musiyano wekupisa unodarika 200 ℃, uye chikafu chinogona kuomeswa nechando nekukurumidza mukati memaminitsi mashanu. Maitiro ekukurumidza echando anoita kuti zvikamu zvehove zvive zvidiki, anodzivirira kurasikirwa nemvura, anodzivirira kuparadzwa kwebhakitiriya nezvimwe zvipembenene, anoita kuti chikafu chisave nekuchinja kwemavara uye mafuta, uye anochengetedza ruvara rwepakutanga, kunaka uye zvinovaka muviri zvehove, saka kuomeswa kwenguva refu kunogonawo kuve nechokwadi chekunaka kwakanyanya.

Muchina wekuchenesa mvura wegungwa une nitrogen yemvura ndiyo yekutanga kushandiswa mukugadzira muchina wekuchenesa mvura wepamusoro nekuda kwekukurumidza kwawo kutonhora, nguva yakareba yekuchengetera, mitengo yakaderera yemidziyo yekushandisa, mitengo yakaderera yekushanda, simba harishandiswi, ruzha uye kugadziriswa. Zvinogona kufanotaurwa kuti tekinoroji yekuchenesa mvura ine nitrogen yemvura ichatsiva zvishoma nezvishoma tekinoroji yekuchenesa mvura nekugadzira muchina wekuchenesa mvura, izvo zvichaunza shanduko huru mukushanda kwemuchina wekuchenesa mvura wekare.

Zvimiro zveChigadzirwa:

○ Tekinoroji yekudzivirira nitrogen yakawanda inoshandiswa ne vacuum yakawanda kuti ive nechokwadi chekuti mvura ine nitrogen yakawanda inorasikirwa nekubuda (<0.8%) uye mutengo wayo wakaderera.

○ Sisitimu yekutarisa nekutarisira zvinhu zvine hungwaru mutangi renitrogen yemvura inogona kutarisa tembiricha nehuwandu hwemvura mutangi rehove panguva chaiyo, kuona kuzadza otomatiki, alarm yezvikanganiso zvakasiyana-siyana, uye kuona kuti michina inoshanda zvakachengeteka. Panguva imwe chete, inopa sisitimu yekuchengetedza zvinhu, iyo inoita kuti kutungamira zvinhu kubva mudura uye mudura kuve pachena nekukurumidza.

○ Magoko emukati nekunze akagadzirwa nesimbi isingatsvedzeri yemhando yepamusoro kuti chigadzirwa chigare kwenguva inopfuura makore gumi.

○Chimiro chetireyi inotenderera mukati chakagadzirirwa kuti zvive nyore kuwana hove. Mamwe mamodheru anogona kuve nechimiro chinotenderera chemagetsi kuti zvikwanise kupinda otomatiki.

○ Inogona kuchengetwa mugasi nemumvura kuti ive nechokwadi chekuti tembiricha yemuromo wetangi inosvika -190 degrees C.

Zvakanakira zvechigadzirwa:

○Kuwanda kwemvura inoyerera yenitrogen
Tekinoroji yekudzivirira kupisa ine vacuum yakawanda inoita kuti nitrogen yemvura irasikirwe nemvura irambe ichidonha zvishoma uye kuti mari yekushandisa igare yakaderera.

○ Tekinoroji itsva inochengetedza kunaka kwayo kwepakutanga
Mvura ine nitrogen inotonhora nekukurumidza, chando chekristaro chekudya chine chando chinobvisa kurasikirwa nemvura, kudzivirira mabhakitiriya nezvimwe zvipembenene zvinokuvadza chikafu, kuitira kuti chikafu chisanyanya kuoxidation uye chinongova nerancidity chete.

○ Sisitimu yekutarisa ine hungwaru
Inogona kuve nehurongwa hwekutarisa hwakangwara, kutarisa tembiricha yega yega yetangi panguva chaiyo, kukwirira kwemazinga emvura, nezvimwewo, inogonawo kuita otomatiki yekuzadza, marudzi ese ealarm yekukanganisa. Panguva imwe chete yekupa sisitimu yekutarisira zvinhu, manejimendi yekutarisira zvinhu mukati nekunze kwekuchengetera.
