Iingqayi zeShell
Sivelisa i-shell shells ezenziwe ngezinto eziphezulu ze-borosilicate ukuqinisekisa ukhuseleko olufanelekileyo kunye nokuzinza kweesampuli. Izinto eziphezulu ze-borosilicate azigcini nje kuphela, kodwa zihambelana kakuhle nezinto ezahlukeneyo zeekhemikhali, ziqinisekisa ukuchaneka kweziphumo zovavanyo.
