Ibikoresho bishya cyangwa byakoreshejwe bigomba kubanza gushirwa mumazi kugirango byoroshe kandi bishongeshe ibikoresho. Ibikoresho bishya byibirahure bigomba gukaraba gusa namazi ya robine mbere yo kubikoresha, hanyuma bigashiramo ijoro ryose hamwe na aside hydrochloric 5%; Ibikoresho by'ibirahuri bikoreshwa akenshi bifatanyirizwa hamwe na poroteyine nyinshi hamwe n'amavuta, byumye nyuma yo kutoroha kubisuzuma, bityo bigomba guhita byinjizwa mumazi meza kugirango bisukure.

1. Ibintu bikeneye kwitabwaho:

Nyuma yo gukora isuku no kuyanduza mbere yo kuyikoresha, yaba ibiryo bya petri bifite isuku cyangwa bidafite ingaruka zikomeye kumurimo, birashobora kugira ingaruka kuri ph yumuco wumuco, niba hari imiti imwe n'imwe, bizabuza gukura kwa bagiteri.

Ibyokurya bya petri bishya byaguzwe bigomba kubanza kwozwa namazi ashyushye, hanyuma bigashyirwa mumuti wa hydrochloric acide hamwe nigice kinini cya 1% cyangwa 2% mumasaha menshi kugirango ukureho ibintu bya alkaline yubusa, hanyuma ukarabe n'amazi yatoboye kabiri.

Niba ushaka umuco wa bagiteri, noneho koresha amavuta yumuvuduko mwinshi (rusange 6.8 * 10 5 Pa yumuvuduko ukabije wamazi), sterilisation kuri 120 ℃ kuri 30min, yumye mubushyuhe bwicyumba, cyangwa ubushyuhe bwumye, ni ugushira isahani ya petri mumatanura. , kugenzura ubushyuhe kuri 120 ℃ ukurikije 2h, urashobora kwica iryinyo rya bagiteri.

Ibyokurya bya petri birashobora gukoreshwa gusa mugukingira n'umuco.

2. Koresha uburyo:

Shira icupa rya reagent kugirango ukoreshwe mumwanya ukwiye aho ukorera, hanyuma urekure agapira k'icupa rya reagent ugomba gukoreshwa.

Shira ibiryo bya petri hagati yumwanya wawe;

Kuraho agapira k'icupa rya reagent hanyuma siphon reagent mumacupa ya reagent hamwe na pipette.

Shira umupfundikizo wibiryo bya petri inyuma yacyo;

Witonze witonze umuco uciriritse muburyo bw'uruhande rumwe rw'isahani;

Shira umupfundikizo ku isahani ya petri;

Shira isahani kuruhande rwayo, witondere kutareka uburyo bwinjira mumwanya muto uri hagati yumupfundikizo no hepfo;

Kuraho ibyatsi byakoreshejwe.
