Ukuphatha i-dewar kunye nokulayisha imithetho

I-Dewar inqanawa yoxinzelelo yentsimbi engenasitayile ene-super vacuum. Sisilinda segesi yegesi esenzelwe ukugcinwa, ukuhambisa kunye nokusetyenziswa kweoksijini ye-atesigen, initrogen yolwelo, i-argon okanye i-carbon okanye i-carbon diokside. Isetyenziselwa ukuthutha ethembekileyo nezoqoqosho kunye nokugcinwa kwegesi yeqondo elingaphantsi kweqondo eliphantsi, kunye nokugcina igesi kunye nokubonelela ngerhasi yeqondo eliphantsi kakhulu kuluhlu olubanzi lwezicelo. Xa kuthelekiswa neesilinda zegesi ezicinezelweyo, inokubamba inani elikhulu lerhasi kwixinzelelo oluphantsi. Ii-Dewors zibonelela ngomthombo wolwelo lwama-biyogenic ekulula ukuphatha.
　　
Ukwenzela ukunciphisa ilahleko ngexesha lokuhamba, xa uphatha kwaye ukhulula i-Dewar, kufuneka sisebenzise le mithetho ilandelayo:
1. Xa uphefumlaIisilinda zegesi, Itrolley, crane okanye i-crane engaphezulu kufuneka isetyenziswe.
　　
2. Sukuhambisa inqanawa yoxinzelelo ngokujija umsesa wokukhusela, kungenjalo unokusibhukuqa ngokulula isilinda igesi kwaye ibangele ukwenzakala komntu kunye nokwenzakala kwezixhobo.
　　
3. Isilinda segesi kufuneka sigcinwe sigcinwa ngokuthe tye ngexesha lokunqanda ukucebisa.
　　
4. Ungaze uvumele i-dewar iqengqele ngokuthe tyaba ngokuthe tye. 5. Xa uhambisa iisilinda zegesi kwilori, sebenzisa ukuphakamisa okanye i-crane ukulayisha iisilinda zegesi kwilori.

6. Emva kweInqanawa yoxinzeleloifakwe kwilori, sebenzisa imitya ye-nylon ukulungisa isikhundla. Sukusebenzisa amakhonkco ukuyilungisa. Kulula ukonakalisa umphezulu we-dewar ngenxa yekhonkco elisigxina, kwaye uthobekile vacuum.
