Micro-Operating Dish

Chii chinonzi Petri ndiro?
Petri dish i cylindrical isina kudzika, girazi rakatenderera rinoshandiswa mumarabhoritari kutsika tupukanana nemasero.Kuti udzidze tupukanana senge mabhakitiriya & mavhairasi pasi pekutarisa kukuru, zvakakosha kuti uzvichengetedze kubva kune mamwe marudzi kana zvinhu.Mune mamwe mazwi, Petri ndiro dzinoshandiswa kutsigira kukura kwema microorganisms.Imwe yenzira dzakanakisisa dzekuita izvi ndeyekubatsirwa kwetsika yetsika mumudziyo wakakodzera.Petri dish ndiyo yakanakisa sarudzo yetsika yepakati ndiro.

Sei Kushandisa Petri ndiro murabhoritari?
Petri dish inonyanya kushandiswa semidziyo yemurabhoritari mumunda webiology & chemistry.Iyo ndiro inoshandiswa kune tsika masero nekupa nzvimbo yekuchengetera uye nekudzivirira kuti irege kusvibiswa.Sezvo ndiro iri pachena, zviri nyore kuona matanho ekukura kwe microorganisms zvakajeka.Saizi yePetri dish inoita kuti ichengetwe pasi pemaikorosikopu yakananga kuti itariswe pasina chikonzero chekuiendesa mundiro ine microscopic.Padanho rekutanga, dhishi rePetri rinoshandiswa muzvikoro nemakoreji kuita zviitiko zvakaita sekutarisa kumera kwembeu.

Mashandisiro ePetri ndiro zvinobudirira murabhoritari
Usati washandisa petri dish zvakakosha kuve nechokwadi kuti yakachena uye isina chero microparticles inogona kukanganisa kuedza.Unogona kuona izvi nekurapa ndiro yega yega yakashandiswa nebleach uye nekuivharisa kuti ishandiswe zvakare.Ita shuwa kuti wabvisa Petri dish usati waishandisa futi.

Kuti uone kukura kwebhakitiriya, tanga nekuzadza ndiro ne agar medium (yakagadzirirwa nerubatsiro red algae).Agar medium ine zvinovaka muviri, ropa, munyu, zviratidzo, mishonga inorwisa mabhakitiriya, nezvimwewo zvinobatsira mukukura kweutachiona.Enderera nekuchengetedza madhishi ePetri mufiriji munzvimbo yakatarisana-pasi.Paunenge uchida mahwendefa etsika, abvise kubva mufiriji uye ashandise kana adzoka pakupisa kwekamuri.

Kufambira mberi, tora sampuli yebhakitiriya kana chero imwe microorganism uye zvishoma nezvishoma uidururire patsika kana kushandisa donje swab kuti uiise pane tsika nenzira yegzag.Ita shuwa kuti hausi kumanikidza zvakanyanya sezvo izvi zvinogona kutyora tsika.

Kana izvi zvangoitwa, vhara ndiro yePetri nechivharo uye uifukidze zvakanaka.Chengetedza pasi peapprox 37ºC kwemazuva mashoma uye woibvumira kuti ikure.Mushure memazuva mashoma, sampuli yako ichave yakagadzirira kumwe kutsvagisa.
