M'malo osinthika komanso ovuta a labotale, zotsalira zomwe zimasiyidwa mu ziwiya zimasiyana chifukwa cha mitundu yosiyanasiyana yoyesera. Momwe mungayeretsere zida zoyesera izimogwira mtima komanso motetezekanthawi zonse wakhala gawo lofunika la kasamalidwe ka labotale. Pochita ndi zotsalira zamitundu yosiyanasiyana, kuyeretsa pamanja nthawi zambiri kumafunikira zida ndi njira zina zoyeretsera. Pazinthu zachilengedwe, titha kugwiritsa ntchito acetone poyeretsa, koma kukhudzana kwanthawi yayitali ndi acetone kungayambitse chizungulire, chifuwa, ndi khungu louma. Pazinthu zakuthupi, nthawi zambiri timagwiritsa ntchito ufa ndi maburashi, koma izi zimawononganso. Poyang'anizana ndi madontho amakani, nthawi zina ma silinda a asidi kapena alkali amafunikira, zomwe mosakayikira zimawonjezera ngozi yogwira ntchito.

Poyerekeza ndi kutsuka pamanja, themakina ochapira magalasiwasonyeza ubwino woonekeratu. Mapangidwe ake amalola kutsuka kwa ziwiya zingapo nthawi imodzi, zomwe zimathandizira kwambiri kutsuka bwino. Kutsekedwa kwamkati kwamkati ndi machitidwe opangira okhawo amachepetsa kwambiri kukhudzana kwachindunji pakati pa ochapa ndi zinthu zovulaza, kuonetsetsa thanzi la ogwira ntchito. Kuonjezera apo, mapangidwe a kabati yamadzi osungiramo madzi amadzimadzi amatsimikiziranso kudzipatula kwathunthu kwa woyeretsa ndi woyendetsa.

Kuphatikiza pakuwongolera chitetezo ndi magwiridwe antchito,labotale glassware washerkomanso bwino kwambiri khalidwe ndi kusasinthasintha kuyeretsa. Kupyolera mu njira zoyeretsera zokhazikika, kuyeretsa kulikonse kumatha kukwaniritsa zomwe zikuyembekezeredwa, ndipo deta yoyeretsera yomwe imalembedwa panthawi yonseyi imakwaniritsa kutsata, kupereka chithandizo cholimba pakuwongolera khalidwe la labotale.

Pamene labotale isankha kugwiritsa ntchito amakina ochapira mabotolo okha basim'malo mwa njira yachikhalidwe yoyeretsera pamanja, kusinthaku sikungochepetsa kwambiri kuvulaza komwe kungachitike kwa ogwiritsa ntchito kuchokera ku zotsalira ndi zoyeretsa panthawi yoyeretsa, komanso kumachepetsa kwambiri chiwopsezo cha kuwonongeka kwa ogwira ntchito kudzera munjira zoyeretsera zofananira. Kuwongolera bwino komanso kusasinthika kwa kuyeretsa.Makina otsuka mabotolo odziwikiratu amatsimikizira kuti kuyeretsa kulikonse kumatsata miyezo ndi njira zomwezo pogwiritsa ntchito njira zoyeretsera zokhazikitsidwa kale, motero amachotsa kusatsimikizika komwe kumachitika chifukwa cha anthu ndikupanga zotsatira zoyeretsera kukhala zodalirika komanso zokhazikika.
