Chigawo chachikulu cha galasi ndi quartz (silika). Quartz imalimbana bwino ndi madzi (ndiko kuti, imakumana ndi madzi). Komabe, chifukwa cha kusungunuka kwapamwamba (pafupifupi 2000 ° C) ndi mtengo wapamwamba wa silica yoyera kwambiri, sikoyenera kugwiritsidwa ntchito Kupanga Misa; Kuonjezera zosintha za netiweki kumatha kutsitsa malo osungunuka a galasi ndikutsitsa mtengo. Zosintha zodziwika bwino za maukonde ndi sodium, calcium, etc.; koma osintha maukonde adzasinthanitsa ma hydrogen ayoni m'madzi, kuchepetsa kukana kwamadzi kwa galasi; kuwonjezera boron ndi Aluminiyamu akhoza kulimbikitsa dongosolo galasi, kutentha kusungunuka kwakwera, koma kukana madzi kwasintha kwambiri.
Zida zopangira mankhwala zimatha kulumikizana mwachindunji ndi mankhwala, ndipo khalidwe lawo lidzakhudza chitetezo ndi kukhazikika kwa mankhwalawa. Kwa galasi lamankhwala, chimodzi mwazofunikira kwambiri pamtundu wake ndi kukana madzi: kutsika kwamadzi kukana, kutsika kwachiwopsezo chakuchita ndi mankhwala, komanso kukweza kwagalasi.
Malingana ndi kukana kwa madzi kuchokera kumunsi kupita kumtunda, galasi lamankhwala likhoza kugawidwa kukhala: galasi la soda laimu, galasi la borosilicate lotsika ndi galasi lapakati la borosilicate. Mu pharmacopoeia, galasi imagawidwa m'kalasi I, Class II, ndi Class III. Kalasi I yagalasi yapamwamba ya borosilicate ndi yoyenera kuyikapo mankhwala a jekeseni, ndipo galasi la soda la laimu la Gulu lachitatu limagwiritsidwa ntchito popanga mankhwala amadzimadzi am'kamwa ndi mankhwala olimba, ndipo si oyenera mankhwala a jekeseni.
Pakadali pano, magalasi otsika a borosilicate ndi magalasi a soda-laimu amagwiritsidwabe ntchito m'magalasi azamankhwala apanyumba. Malinga ndi "In-deep Research and Investment Strategy Report on China's Pharmaceutical Glass Packaging (2019 Edition)", kugwiritsidwa ntchito kwa borosilicate mu galasi lanyumba mu 2018 kunangokhala 7-8%. Komabe, popeza United States, Europe, Japan, ndi Russia onse amalamula kugwiritsa ntchito magalasi osalowerera ndale a borosilicate pokonzekera jekeseni ndi kukonzekera kwachilengedwe, magalasi apakatikati a borosilicate akhala akugwiritsidwa ntchito kwambiri m'makampani azamankhwala akunja.
Kuphatikiza pamagulu malinga ndi kukana kwamadzi, malinga ndi njira zosiyanasiyana zopangira, galasi lamankhwala limagawidwa kukhala: mabotolo opangidwa ndi mabotolo oyendetsedwa. Botolo lopangidwa ndikulowetsa mwachindunji madzi agalasi mu nkhungu kuti apange botolo la mankhwala; pomwe botolo lowongolera ndikuyamba kupanga madzi agalasi kukhala chubu lagalasi, kenako ndikudula chubu lagalasi kuti mupange botolo lamankhwala
Malinga ndi lipoti la Analysis Report of the Industry of Glass Packaging Equipment for Injections mu 2019, mabotolo a jakisoni anali 55% ya magalasi onse amankhwala ndipo ndi amodzi mwazinthu zazikulu zamagalasi azamankhwala. M'zaka zaposachedwa, kugulitsa ma jakisoni ku China kukupitilirabe, ndikupangitsa kuti kufunikira kwa mabotolo a jakisoni kupitirire kukwera, ndipo kusintha kwa mfundo zokhudzana ndi jakisoni kudzayendetsa kusintha kwa msika wamagalasi amankhwala.
