I-Aijiren COD I-TUBE yenziwa ngeglasi ye-borossilicate, enokunciphisa utshintsho lwe-PH kunye nokungcoliseka okunokuthi kuhlawulwe kwiglasi yesoda. Ityhubhu yokugaya iglasi inokusetyenziselwa uhlalutyo kumaqondo obushushu angaphezulu kwe-130 degrees Celsius. Ifakwe kwi-labhoratri yokugcina ilebhu yeenjongo ezahlukeneyo kwaye inokubambe phantse nantoni na. I-gasket yenziwa nge-jerket ye-ptfey yerabha, enendlela eyomeleleyo yokutywina kwaye inokumelana nokuntywila okwahlukeneyo iikhemikhali. Ityhubhu yovavanyo yeCOD incinci ngobukhulu kunye nokukhanya kubunzima. Inokuvavanywa ngaphandle kokuba ezinye izixhobo zelebhu kunye neengcali; Kuthatha kuphela imizuzu engama-3-5 kuvavanya isampulu, ngaphandle kwezinto ezongezelelweyo okanye izixhobo kwaye kulula ukusebenza.
