Beaker, galasi looneka ngati losavuta la labotale, kwenikweni limagwira ntchito yofunika kwambiri pakuyesera mankhwala. Limapangidwa ndi galasi kapena galasi losatentha ndipo lili ndi mawonekedwe ozungulira okhala ndi kagawo mbali imodzi pamwamba kuti madzi azithiridwa mosavuta. Lili ndi ntchito zosiyanasiyana ndipo lingagwiritsidwe ntchito potenthetsa, kusungunula, kusakaniza, kuwiritsa, kusungunula, kusungunuka, kusungunula, kugwetsa, kunyowetsa komanso kuyeretsa zinthu zoyambitsa mankhwala. Ndi chotengera chochitira zinthu mu labotale.

Komabe, ma beakers nthawi zambiri amasiya zotsalira zosiyanasiyana za mankhwala akagwiritsidwa ntchito. Ngati sanatsukidwe bwino, sadzangokhudza zotsatira za kuyesa kotsatira, komanso akhoza kuopseza thanzi la oyesera. Chifukwa chake, ntchito yoyeretsa ma beakers ndi yofunika kwambiri.

Njira yachikhalidwe yotsukira mabeki ndi kutsuka ndi manja. Ngakhale kuti njira iyi imatha kuyeretsa pang'ono, siyothandiza ndipo ingayambitse kuyeretsa kosayera chifukwa chogwiritsa ntchito molakwika.zokha zokhachotsukira magalasi cha labotaleyabweretsa kusintha pa ntchito yoyeretsa ma beakers.

Njira yotsukira ma beakers ndizokha zokhachotsukira ziwiya zagalasindi yosavuta komanso yothandiza. Choyamba, ikani ma beakers kuti ayeretsedwe pa malo apadera a dengu lachotsukira magalasi cha labotalekuti muwonetsetse kuti ma beakers ndi olimba ndipo sagundana. Kenako, sankhani pulogalamu yoyenera yoyeretsera ndi chotsukira kutengera zinthu zomwe zili mu beakers ndi mtundu wa zotsalira. Mukayamba kugwiritsa ntchito zida, chotsukira mabotolo chidzamaliza zokha njira zingapo monga kutsuka, kuyeretsa, kutsuka, ndi kuumitsa.

Pa nthawi yoyeretsa, tsukani bwino makoma amkati ndi akunja a beaker. Nthawi yomweyo, chotsukiracho chidzagwira ntchito ndi madzi kuti chichotse bwino madontho ndi zotsalira pamwamba pa beaker. Pambuyo poyeretsa, chotsukira mabotolo chidzatsuka kangapo kuti chitsimikizire kuti chotsukiracho chachotsedwa ndikupewa kusokoneza kuyesa kwotsatira.

Ubwino wazokha zokhamagalasimakina ochapiraPa ma beakers oyeretsera, ma beakers oyeretsera ali mu kukhazikika kwawo komanso kudalirika kwawo. Sikuti amangowonjezera bwino ntchito yoyeretsa ndikuchepetsa katundu kwa ogwira ntchito yoyesera, komanso amaonetsetsa kuti ntchito yoyeretsayo ikuyenda bwino komanso yokhazikika komanso kupewa mavuto oyeretsa odetsedwa omwe amayamba chifukwa cha kusagwira ntchito bwino kwa anthu.
