1. Ukugcwalisa ngokugcwalisa, ukulungelelaniswa, i-buzz ephantsi.
2. Inkqubo egqityiweyo ngokuzenzekelayo njenge-tube, irejista ye-elektroni, i-Inert Gases igcwalisa (ngokuzithandela), ukugcwaliswa kwezixhobo kunye nokupeyinta inombolo, kunye nemveliso yemveliso, kunye nokugqitywa kwemveliso.
3. Ngokukhawuleza uhlengahlengise kwaye kufanelekile kwaye ilungele ukwahlukahlukahlukana kwaye iyahluka kwimveliso.
4. Akukho tyhubhu akukho msebenzi wokugcwalisa kunye nesilumkiso ukuba impazamo ye-tube ibekwe okanye uxinzelelo oluphantsi, umatshini wokumisa ozenzekelayo ukuba uvula ucango olukhuselayo.
