Izikhenkcisi ezinobushushu obuphantsi kakhulu (Iifriza ze-ULT) zenzelwe iinjongo ezikhethekileyo zokugcina ngokukhuselekileyo amayeza, imizekelo, izitofu, i-erythrocyte, ihemameba, i-DNA/RNA, ibhaktheriya, amathambo, amadlozi kunye nezinye izinto eziphilayo.ENenwell, wethuiifriji eziphantsi kakhulubanoluhlu olubanzi lobushushu ukusuka -25℃ ukuya -164℃, ubushushu buhla ngokukhawuleza emva kokuvulwa, bade badibanise izikhenkcisi zegesi, ezonga amandla kunye nokusingqongileyo ukunika iimeko ezingaguqukiyo nezifanelekileyo.Ukongeza kwiinketho zeqondo lokushisa, kukho ukhetho oluninzi ukuhlangabezana neendawo ezahlukeneyo zokugcina, imilinganiselo kunye nezinye iimfuno.Iintlobo ezininzi zesikhenkcezisi ziyafumaneka kwiinketho zakho, isikhenkcisi se-ULT esithe tye sivumela ukufikelela-ngaphakathi, amacandelo okugcina ayahlengahlengiswa, i-ULT engaphantsi kwekhawuntara kunye ne-counter-top freezers inokukunceda ugcine indawo ukuba unendawo encinci yokusebenza, kunye nesifuba. Isikhenkcisi se-ULT silingana nezinto ezingasetyenziswa kancinci onokuthi uzigcine kwaye uzigcine ixesha elide.Izikhenkcisi zethu zobushushu obuphantsi kakhulu &iifriji zonyangozifanelekile izicelo kwizibhedlele, izikhululo zebhanki yegazi, iilebhu zophando, isikhululo sokulwa nobhubhane njalo njalo.
