Kurongeka kwePetri ndiro——
1. Maererano nekushandiswa kwakasiyana-siyana kwezvokudya zvetsika, zvinogona kugoverwa kuva sero tsika ndiro uye bhakitiriya tsika ndiro.
2. Inogona kukamurwa kuita mapurasitiki petri ndiro uye girazi petri ndiro maererano neyakasiyana yekugadzira zvinhu, asi mazhinji ekunze ekunze petri ndiro uye anoraswa petri ndiro zvinhu zvepurasitiki.
3. Maererano nehukuru hwakasiyana, vanogona kuparadzaniswa kuva 35mm, 60mm uye 90mm muhupamhi.150mm Petri ndiro.
4. Maererano nekusiyana kwekuparadzanisa, inogona kugoverwa mu 2 yakasiyana Petri ndiro, 3 yakasiyana Petri ndiro, nezvimwewo.
5. Zvishandiso zvetsika ndiro zvakakamurwa kuva mapoka maviri, kunyanya mapurasitiki negirazi.Girazi rinogona kushandiswa kugadzira zvidyarwa, microbial tsika, uye inoteedzera tsika yemasero emhuka.Zvigadzirwa zvepurasitiki zvinogona kunge zviri zve polyethylene, zvinogona kushandiswa kamwe chete kana kakawanda.Iwo akakodzera murabhoritari inoculation, scribing, uye mabhakitiriya kupatsanurwa oparesheni, uye anogona kushandiswa kurimwa chirimwa zvinhu.
Nei iyo Petri dish yakatsikitsira pasi mune lithographic tsika--
1. Panguva yekushanda, panogona kunge kune madonhwe emvura kana mabhakitiriya pavhavha ye petri dish.Iyo yakadzika pasi tsika inogona kudzivirira madonhwe emvura kana ma microorganisms ari pachivharo kubva pakudonha pa petri dish.
2. Munguva yehutsika, mabhakitiriya achabudisa mamwe metabolites anokuvadza kukura uye kubereka kwebhakitiriya panguva yekugadzirwa kwemagetsi, kusunungura kupisa uye kubuda mvura.Kana mabhakitiriya asina kusimudzwa akadzikama, madonhwe emvura achawira mutsika yemagariro, zvichikanganisa kukura kwemakoloni.
3. Kana chinangwa chetsika chiri kuunganidza bhakitiriya metabolites, uye metabolites inonyungudika nyore nyore mumvura, inverted tsika inogona kufambisa kuunganidza.
Munguva yehutsika, pachava nemhepo yakawanda yemvura mundiro yetsika, uye condensation yemvura inopisa pavhavha yedhishi ichabudisa madonhwe emvura.Kana chikafu chetsika chikaiswa panzvimbo yakakodzera, madonhwe emvura achaparadzira makoroni.Nenzira iyi, boka guru rinogona kupararira mumapoka maduku akawanda, zvichikonzera dambudziko guru rekurima uye kuverenga kwebhakitiriya.Kana ikakonzerwa, tsika yetsika iri pamusoro uye ndiro iri pasi pechifukidziro, uye madonhwe emvura haazodonhedzi pakoloni.
Kungwarira pakushandiswa kwePetri ndiro——
1. Mushure mekuchenesa uye kuuraya hutachiona kusati kwashandiswa, kuchena kwemidziyo yetsika kune simba guru pane basa, iro rinogona kukanganisa pH yetsika yetsika.Kana pane mamwe makemikari, anodzivisa kukura kwebhakitiriya.
2. Madhishi etsika achangobva kutengwa anofanira kushambidzwa nemvura inopisa kutanga, uye ozonyudzwa mu 1% kana 2% hydrochloric acid solution kwemaawa akawanda kuti abvise mahara alkaline zvinhu, uye osuka kaviri nemvura yakasvibiswa.
3. Kurima mabhakitiriya, shandisa high pressure steam (kazhinji 6.8 * 10 Pa high pressure steam kusvika kune 5th power), isa 30min pa120 ℃, iomese patembiricha yekamuri, kana kushandisa kupisa kwakaoma kuti sterize, kureva kuisa. dhishi yetsika muchoto, dzora tembiricha pa120 ℃ kwe2h, wobva wauraya mazino ebhakitiriya.
4. Chete sterilized tsika ndiro anogona kushandiswa inoculation uye kurima.

1. Panguva yekushanda, panogona kunge kune madonhwe emvura kana mabhakitiriya pavhavha ye petri dish.Iyo yakadzika pasi tsika inogona kudzivirira madonhwe emvura kana ma microorganisms ari pachivharo kubva pakudonha pa petri dish.
2.

3. Kana chinangwa chetsika chiri kuunganidza bhakitiriya metabolites, uye metabolites inonyungudika nyore nyore mumvura, inverted tsika inogona kufambisa kuunganidza.
