Yongyue Steil Slian Petch Chikhalidwe Chakudya

Y preggy azipatala zopanga zinsinsi, kuphatikizapo chitoliro cha serry, chinsinsi cha khungu, ercloginer chipwirikiti, ndi zina zambiri. Banja lathu logulitsa limaphatikizanso kubala masiketi ndi singano, machubu owiritsa etc., omwe amagwiritsidwa ntchito poyesa. Malinga ndi kukula, mbale zathu za Petri zitha kugawidwa mu 35mm, 90mm, 100mm, 120mm, 130mm, 150mm. Malinga ndi magawano osiyanasiyana, amatha kugawidwa m'masamba 2, mbale za Petri omwe ali ndi magawo atatu, mbale za Petri ndi magawo 4 ndi zina zotero.

Zakudya za Petri ndizoyenera kugawanika, zipatala, zopangira zachilengedwe, makampani ena opanga mabakiteriya komanso mayeso oyeserera.

Pamiyala yaulimi, yofufuzira zamadzi komanso kafukufuku wina wasayansi, imagwiritsidwa ntchito popanga zopanga ndi kufufuza kwa mbewu, mbewu, tizilombo tosiyanasiyana. M'makompyuta kapena mafakitale ena, amagwiritsidwa ntchito ngati zotengera.

Zakudya za Petri pulasitiki zimapangidwa ndi polyethylene ndipo ndizoyenera kuzigwiritsa, kubalalitsa komanso kudzipatula kwa mabakiteriya mu labotale ndi kukulitsa zinthu zomera. Kuphatikiza apo, zitha kugwiritsidwa ntchito kanthawi kangapo, kutengera cholinga.

Kodi ndichifukwa chiyani mbale ya Petri iyenera kusinthidwa mukamalima tizilombo?

1. Kuchepetsa pang'onopang'ono:

Kutembenuza chipembedzo pansi kumatha kuchepetsa kuchepa kwa madzi a sing'anga mbale; Madzi osinthika amasinthasintha madontho amadzi pa chivindikiro chapamwamba, chomwe chimakhudza mawonekedwe amtunduwu ndikuwerengera zotsatira ndipo zimapangitsa kuti zisawonekere kuwunika.

2. Kufikira kosavuta:

Chivindikiro cha mbale ya petri ndi lalikulu ndipo pansi ndi yaying'ono.

Pakakhala zowongoka, ndikosavuta kutulutsa ndi chivundikiro chokha, ndikuwonetsa zachikhalidwe mumikhalidwe mbale, zomwe zitha kupangitsa kuti chikhalidwecho chizikhala chodetsedwa kapena chipembedzo chodetsedwa.

3. Kuwonetsera bwino:

Chakudya cha Petri chitha kusinthidwa kuti athetse kufalikira kwa madera a mbale mu mbale ya petri, komwe kumatha kupangika kwa madera amodzi ndipo ndi yabwino kwambiri pakuwona.

4. Pewani kuipitsa: Kusokonekera kumatha kuletsa nthunzi wa petri ku chivundikiro cha mbale ya petri ndikugubuduza pachikhalidwe, kumayambitsa kuipitsa komanso kukhudza kukula kwa ma microorganisms sing'anga .

5. Kupereka kosavuta:

Nthawi zina cholinga cha chikhalidwe ndikuyenera kutolera metabolites ya mabakiteriya. Komabe, ma metabolites ena amasungunuka mosavuta m'madzi. Pamene mbale ya Petri imakutidwa, madzi omenyedwa adzatuluka, ndikupangitsa maderawo kuti ayendetse.initse mankhwalawa osavuta kusonkhanitsa ma metabolites ndikuwerengera kapena kudzipatula, etc.

6. Pewani kusokonekera:

Mu cholumikizira cham'kati, mankhwala azikhalidwe amatha kutembenuzidwa mozondoka kuti achepetse mpweya pansi pa sing'anga pamtunda, kuchepetsa kuchuluka kwa madzi apakatikati, ndikupangitsa kuti sing'anga yovuta.
