Iityhubhu zenkcubeko yeborosilicate ezilahlwayo ziityhubhu zovavanyo lwelabhoratri ezilahlwayo ezenziwe ngeglasi yeborosilicate ekumgangatho ophezulu. Ezi ityhubhu ziqhele ukusetyenziswa kuphando lwezenzululwazi, iilebhu zonyango, kunye nezicwangciso zemizi-mveliso kwimisebenzi efana nenkcubeko yeeseli, ukugcinwa kwesampulu, kunye nokuphendula kwamachiza. Ukusetyenziswa kweglasi ye-borosilicate kuqinisekisa ukuxhathisa okuphezulu kwe-thermal kunye nokuzinza kweekhemikhali, okwenza ityhubhu ilungele ubuninzi bezicelo. Emva kokusetyenziswa, iityhubhu zovavanyo ziqhele ukulahlwa ukuthintela ungcoliseko kunye nokuqinisekisa ukuchaneka kovavanyo lwexesha elizayo.
