Kugwiritsa ntchito makina ochapira mabotolo odzipangira okha poyeretsa magalasi, n'kosiyana ndi njira zoyeretsera ndi manja. Chonde samalani ndi njira zina zodzitetezera pakugwiritsa ntchito makina ochapira mabotolo opangidwa ndi labu.Chotsukira Magalasi cha Laboratory.
1. Ziwiya zazing'ono zamagalasi monga ma flask a triangular, ma flask odzaza, machubu ogaya chakudya, ndi masilinda oyezera ziyenera kutsukidwa ndi jakisoni momwe zingathere.
2. Ma flask ang'onoang'ono a triangular, ma beakers, ndi zina zotero akhoza kutsukidwa poika ma racks;
3. Pipette imatsukidwa ndi choyikapo chapadera cha pipette;
4. Mabotolo obayira jakisoni, machubu ang'onoang'ono oyesera, machubu oyezera kutentha, ndi zina zotero zimatha kutsukidwa ndi mabotolo obayira jakisoni;
5. Ndi bwino kugawa ndi kuyeretsa malinga ndi zinthu zoipitsa (zoipitsa zachilengedwe ndi zinthu zoipitsa zopanda chilengedwe, tizilombo toyambitsa matenda, ndi zina zotero);
Kusamalitsa:
1. Mukatsuka mitsuko (ma beakers, ma flasks ang'onoang'ono a triangular, ndi zina zotero) ndi soketi, ikani mitu yothandizira yambiri momwe mungathere, ndipo yesetsani kupewa kuyika mutu wothandizira umodzi wokha;
2. Mukayeretsa, yesani kusonkhanitsa kuchuluka kokwanira koyeretsera magalasi amtundu womwewo.
3. Zipewa zopepuka za aluminiyamu, makoko, ndi mabotolo oyezera ziyenera kuyikidwa mu dengu la chimango, ndipo zivindikiro ziyenera kuphimbidwa kuti zitsukidwe pamodzi.
4. Mukagwiritsa ntchito choyikapo cha botolo la chitsanzo, kutalika kwake kuyenera kuyikidwa pamalo omwewo momwe mungathere, ndikuphimba chivindikiro kuti chiyeretsedwe kuti chisagwe panthawi yoyeretsa.
5. Mukagwiritsa ntchito dengu loyeretsera jakisoni, mukatsegula, payenera kukhala malo pansi pa galasi ndi pamwamba pa mutu wa jakisoni. Pansi pa chidebecho sichitha kufika pamwamba pa mutu wa jakisoni, ndipo chikhoza kusinthidwa mmwamba ndi pansi.
Kusankha pulogalamu:
1. Njira zoyeretsera zosagwiritsidwa ntchito mwachilengedwe zitha kusankhidwa;
2. Njira zoyeretsera zachilengedwe;
3. Njira zoyeretsera bwino;
4. Njira zoyeretsera zonse; 5. Njira zoyeretsera pulasitiki;
