Emkhakheni webhayoloji nemithi, ukuvikelwa kwamasampula ezinto eziphilayo kubaluleke kakhulu.Ngaphandle kokuthi "ulele" ezindaweni zokucwaninga nezibhedlela, lawa masampuli avame ukudinga izinto zokuhamba.Ukugcina ngokuphephile noma ukuthutha lawa masampuli ayigugu emvelo, ukusetshenziswa kwamathangi e-nitrogen ayiketshezi emazingeni okushisa aphansi kakhulu angu-196 degrees Celsius kudingekile.
Amathangi e-nitrogen ewuketshezingokuvamile ahlukaniswa abe izinhlobo ezimbili: amathangi okugcina i-nitrogen ewuketshezi kanye namathangi okuthutha e-nitrogen ewuketshezi.Amathangi esitoreji asetshenziswa ngokuyinhloko ukuze kulondolozwe i-nitrogen ewuketshezi ngaphakathi endlini, enamandla amakhulu namavolumu angafaneleki kancane ukuthutha amabanga amade ezifundeni zokusebenza.
Ngokuphambene, amathangi ezokuthutha e-nitrogen ewuketshezi angasindi futhi aklanyelwe ukuhlangabezana nezidingo zokuhamba.Ukuqinisekisa ukulungela ukuthutha, lamathangi enziwa umklamo okhethekile wokulwa nokudlidliza.Ngaphandle kwesitoreji esimile, zingasetshenziselwa ukuthutha kuyilapho zigcwele i-nitrogen ewuketshezi, kodwa kufanele kuthathwe izinyathelo zokugwema ukungqubuzana okukhulu nokudlidliza.
Isibonelo, i-Haier Biomedical's Liquid Nitrogen Biobanking Series iyakwazi ukuthutha amasampula ebhayoloji ezindaweni zokushisa eziphansi kakhulu.Ukuklama kwayo kwesakhiwo kuvimbela ngempumelelo ukukhululwa kwe-nitrogen ewuketshezi ngesikhathi sokuthutha.
Ezimweni lapho abasebenzi bedinga ukuthuthwa ngendiza kwesikhathi esifushane, i-Biobanking Series ibonakala iwusizo olukhulu.Lolu chungechunge lunesakhiwo esiqinile se-aluminium esinezicaciso zevolumu ezinhlanu ongakhetha kuzo, iwaranti ye-vacuum yeminyaka emi-3, eqinisekisa ukuphepha okude kwamasampula.Amathangi angagcina izitsha ze-cryogenic noma amashubhu okuqandisa ajwayelekile angu-2ml, afakwe isihlukanisi esikhethekile sensimbi engenasici endaweni yokugcina kanye nomzimba owuketshezi we-nitrogen.Izivalo ezikhiyekayo ozikhethela zona zengeza isendlalelo esengeziwe sokuvikeleka kusampula yesitoreji.
Nakuba ukwakheka kwamathangi e-nitrogen ewuketshezi kusiza ezokuthutha, izinyathelo zokuphepha ezimbalwa kufanele zibhekwe kuyo yonke inqubo yokuthutha.Okokuqala, kubalulekile ukuqinisekisa ukuthi wonke ama-valve e-valve ethangini le-nitrogen eliwuketshezi asesimweni esifanayo nangesikhathi sokugcina.Ukwengeza, ithangi kufanele libekwe ngaphakathi kohlaka lwamapulangwe olune-cushion efanele, futhi uma kunesidingo, livikelwe emotweni yokuthutha kusetshenziswa izintambo ukuvimbela noma yikuphi ukunyakaza ngesikhathi sokuthutha.
Ngaphezu kwalokho, ukusebenzisa okokugcwalisa phakathi kwamathangi kubalulekile ukuze kuvinjwe ukugingqana kanye nomthelela ngesikhathi sokuthutha, ngaleyo ndlela kugwenywe izingozi.Lapho kulayishwa futhi kuthululwa amathangi e-nitrogen ewuketshezi, kufanele kuqashelwe ukuze kuvinjelwe ukuthi angashayisani.Ukuwahudulela phansi akukhuthazwa kakhulu, njengoba kungase kunciphise isikhathi sokuphila samathangi e-nitrogen ayiketshezi.
