Beaker, magalasi owoneka ngati osavuta a labotale, amagwira ntchito yofunika kwambiri pakuyesa mankhwala. Amapangidwa ndi galasi kapena galasi lopanda kutentha ndipo ali ndi mawonekedwe a cylindrical ndi notch kumbali imodzi ya pamwamba kuti azitha kuthira zakumwa mosavuta. Zili ndi ntchito zosiyanasiyana ndipo zingagwiritsidwe ntchito potenthetsa, kusungunula, kusakaniza, kuwiritsa, kusungunula, kusungunuka kwa evaporation, dilution, mpweya ndi kufotokozera za reagents mankhwala. Ndi chotengera chochitira mu labotale.

Komabe, ma beaker nthawi zambiri amasiya zotsalira zamankhwala osiyanasiyana akagwiritsidwa ntchito. Ngati satsukidwa mwaukhondo, sizidzangokhudza zotsatira za kuyesa kotsatira, komanso zingakhale zoopsa ku thanzi la oyesera. Chifukwa chake, ntchito yoyeretsa ma beaks ndiyofunikira kwambiri.

Njira yotsuka mitsuko yachikale kwambiri ndiyo kuyeretsa pamanja. Ngakhale kuti njira imeneyi imatha kuyeretsa zinthu zina, siigwira ntchito bwino ndipo imatha kuyambitsa kuyeretsa kodetsedwa chifukwa chosagwira ntchito bwino. Kuwonekera kwazodziwikiratulabotale glassware washerwabweretsa kusintha pakutsukidwa kwa mabeker.

Njira yotsuka ma beaks ndi azodziwikiratumakina ochapira magalasindi yosavuta komanso yothandiza. Choyamba, ikani ma beaks kuti atsukidwe pachoyikapo chapadera cha dengu lalabotale glassware washerkuwonetsetsa kuti ma beak ndi okhazikika komanso osawombana. Kenako, sankhani pulogalamu yoyenera yoyeretsa ndi wothandizira kuyeretsa kutengera zinthu za beaker komanso momwe zotsalirazo zilili. Pambuyo poyambitsa zida, makina ochapira botolo amangomaliza masitepe angapo monga kuchapa, kuyeretsa, kutsuka, ndi kuyanika.

Pakuyeretsa, tsukani bwino makoma amkati ndi akunja a beaker. Panthawi imodzimodziyo, woyeretsayo adzagwira ntchito ndi madzi otuluka kuti achotse bwino madontho ndi zotsalira pamwamba pa beaker. Pambuyo poyeretsa, wotsuka botolo adzachita ma rinses angapo kuti atsimikizire kuti chotsukiracho chimachotsedwa ndikupewa kusokoneza kuyesera kotsatira.

Ubwino wa azodziwikiratugalasimakina ochapirakuyeretsa beakers lagona mu standardization ake ndi kudalirika. Sizingangowonjezera kuyeretsa bwino komanso kuchepetsa kulemetsa kwa ogwira ntchito yoyesera, komanso kuwonetsetsa kusasinthika ndi kukhazikika kwa ntchito yoyeretsa ndikupewa zovuta zoyeretsa zomwe zimayambitsidwa ndi ntchito yosayenera ya anthu.
