Le nkomishi yekhofi ekhanyayo, edizayinwe "ngekhwalithi ebonakalayo" njengomqondo wayo oyinhloko, igqashula emikhawulweni yombala wezinkomishi zendabuko, okuvumela umbala ocebile wekhofi nokucaca okucacile kwetiye ukuthi kube ukugxila okubukwayo. Umzimba wenkomishi wenziwe ngengilazi ephezulu ye-borosilicate, equkethe amazinga aphezulu e-silicon dioxide ne-silicon kunengilazi evamile. Lokhu kwakheka kwenza isakhiwo sengilazi sihlangane futhi ama-molecule ahleleke ngokulinganayo, avimbele ukucwiliswa kwezinto eziyingozi emthonjeni. Ngaphezu kwalokho, ukuze kuqinisekiswe ukuhlanzeka kwempahla, impahla eluhlaza ingena inqubo yokuhlanza ngaphambi kokucubungula ukuze kukhishwe ukungcola kwensimbi. Okokugcina, ithola ukwelashwa{4}}okuncibilika kwezinga lokushisa okuphezulu kanye ne-vacuum degassing, okuholela kumzimba wenkomishi okhanyayo ongenawo amaphuzu ekristalu namabhamuza.
Izakhiwo zengilazi ye-borosilicate zikhuliswa kule nkomishi yekhofi esobala. I-coefficient yayo yokunwetshwa kwe-thermal iyingxenye eyodwa{1}}kuthathu kuphela yengilazi evamile, okusho ukuthi ingamelana kalula nokwehluka kwezinga lokushisa elidlulele. Ukuze kuthuthukiswe ukuqina kwendebe, ibhekana nenqubo yokuqinisa umzimba, yakha isendlalelo sokucindezeleka esicindezelayo esilinganayo phezu kwendawo, okuholela ekuqineni komthelela okuthuthukisiwe uma kuqhathaniswa nezinkomishi zengilazi ze-borosilicate ezivamile. Ekusetshenzisweni kwansuku zonke, amaqhubu ngengozi noma amaconsi amancane ngeke aphuke kalula ngaphandle uma engaphansi komthelela onzima. Ngaphansi kunomkhawulo oqinile, ophansi, ongagcini nje ngokuthuthukisa ukuzinza kwenkomishi futhi uvimbele ukuthinta, kodwa futhi udala iphansi elibushelelezi, eliyisicaba elingeke lishiye imihuzuko kunoma iyiphi indawo.
Inkomishi yekhofi esobala iklanywe nge-ergonomics emnyombweni wayo, ehlanganisa ukusebenza kahle nobuhle. Ihlanganisa umklamo wodonga olujiyile; lobu bukhulu bunqunywe ngokuhlolwa ukuze kugwenywe ukuzwa okuxegayo ngenxa yokuba mncane ngokwedlulele, noma ukubukeka okuyinqwaba nokukhungathekile ngenxa yogqinsi oludlulele, kunikeza-umuzwa oqinile olungile uma ubanjwe entendeni. Udonga olujiyile futhi lwakha isendlalelo semvelo sokuvikela ukushisa, esivimbela ukuzwa okushisayo lapho ubambe inkomishi ngemva kokuthela uketshezi olushisayo, okuvumela ukubamba ngokunethezeka ngisho nangaphandle komkhono. Unqenqema lwenkomishi yekhofi esobala luqedwa kusetshenziswa inqubo ekabili yokugaya okubandayo nokupholisha ilangabi. Okokuqala, imiphetho yengilazi emagebhugebhu isuswa ngokugaya, bese ipholishwa -ebangeni lokushisa eliphansi, inqubo ephindaphindwayo kuze kube yilapho umphetho ufinyelela ijika elifanele, eliyindilinga.
Imvelo esobala yenkomishi yekhofi ecacile iyenza ibe insiza ehlukahlukene. Ehhovisi, ihlangana ngaphandle komthungo endaweni yokusebenza encane; ekhaya, ilungele ukubamba ama-latte futhi ujabulele ukudla kwasekuseni; futhi emibuthanweni nabangane, ingasetshenziswa ukwenza amatiye ezithelo ezinhlobonhlobo, ibe yinto evelele ebonwayo etafuleni. Okungcono nakakhulu, izinkomishi zekhofi ezicacile kulula ukuzihlanza. Indawo yengilazi ebushelelezi ayigcini kalula ikhofi noma amabala etiye; ukugeza okulula ngamanzi yikho konke okudingekayo ukuze kubukeke kusha. Kungenjalo, kungaba umshini wokuwasha izitsha ophephile ekuhlanzeni ngokushesha nakalula.
