I-Micro-Operating Dish
Incazelo emfushane:
Isetshenziselwa ukubuka ukuma kwama-oocyte, amaseli e-cumulus ngaphansi kwe-microscope, ukucubungula ama-oocyte amangqamuzana e-peripheral granular, ukujova isidoda ku-ovum.
Yiziphi izitsha zePetri?
I-Petri dish iyisilinda esingashoni, ingilazi eyindilinga esetshenziswa kumalabhorethri ukwenza ama-microorganisms namaseli ahlukene.Ukutadisha ama-microorganisms afana namagciwane nama-virus ngaphansi kokubhekwa kakhulu, kubalulekile ukuwagcina ehlukanisiwe kwezinye izinhlobo zezilwane noma izakhi.Ngamanye amazwi, izitsha zePetri zisetshenziselwa ukusekela ukukhula kwama-microorganisms.Enye yezindlela eziphumelela kakhulu zokwenza lokhu ngosizo lwe-culture medium esitsheni esifanele.I-Petri dish iyisinqumo esingcono kakhulu sepuleti eliphakathi kwesiko.
Leli cwecwe lasungulwa isazi samagciwane saseJalimane uJulius Richard Petri.Petri dish akumangalisi, ebizwa ngegama lakhe.Selokhu yasungulwa, izitsha zePetri seziphenduke enye yemishini yaselabhorethri ebaluleke kakhulu.Kulesi sihloko se-Science Equip, sizothola ngokuningiliziwe ukuthi zisetshenziswa kanjani izitsha ze-Petri njengamalabhorethri emishini yesayensi nezinjongo zayo ezihlukahlukene.
Kungani Kufanele Usebenzise izitsha zePetri elabhorethri?
Isitsha sePetri sisetshenziswa kakhulu njengemishini yaselabhorethri emkhakheni webhayoloji namakhemikhali.Isitsha sisetshenziselwa ukwenza amaseli ngokunikeza indawo yokugcina nokuwavimbela ukuthi angangcoli.Njengoba isidlo sisobala, kulula ukubona ngokucacile izigaba zokukhula kwama-microorganisms.Usayizi wesitsha sePetri usenza sikwazi ukugcinwa ngaphansi kwesibonakhulu ngokuqondile ukuze sibukwe ngaphandle kwesidingo sokusidlulisela epuletini elincane.Ezingeni eliyisisekelo, i-Petri dish isetshenziswa ezikoleni nasemakolishi ukwenza imisebenzi efana nokubona ukuhluma kwembewu.
Ungazisebenzisa kanjani izitsha zePetri ngokuphumelelayo elabhorethri
Ngaphambi kokusebenzisa isitsha se-petri kubalulekile ukwenza isiqiniseko sokuthi sihlanzekile ngokuphelele futhi asinanoma yimaphi ama-microparticles angase athinte ukuhlolwa.Ungaqinisekisa lokhu ngokuphatha zonke izitsha ezisetshenzisiwe nge-bleach bese uzifaka inzalo ukuze zisetshenziswe futhi.Qiniseka ukuthi uyasibulala amagciwane esitsheni sePetri ngaphambi kokusisebenzisa.
Ukuze ubuke ukukhula kwamabhaktheriya, qala ngokugcwalisa isidlo nge-agar medium (elungiselelwe ngosizo lwe-algae ebomvu).I-agar medium iqukethe izakhi, igazi, usawoti, izinkomba, ama-antibiotics, njll. esiza ekukhuleni kwama-microorganisms.Qhubeka ngokugcina izitsha zePetri esiqandisini endaweni ebheke phansi.Uma udinga amapuleti e-culture, wakhiphe esiqandisini futhi uwasebenzise uma esebuyile ekamelweni lokushisa.
Ukuqhubekela phambili, thatha isampula yebhaktheriya nanoma iyiphi enye i-microorganism bese uyithela kancane kusiko noma usebenzise i-swab kakotini ukuze uyigcobe esikweni ngendlela emazombezombe.Qiniseka ukuthi awufaki ingcindezi enkulu ngoba lokhu kungase kwephule isiko.
Uma lokhu sekwenziwe, vala isitsha sePetri ngesivalo bese usimboza kahle.Gcina ngaphansi kuka-37ºC izinsuku ezimbalwa futhi uyivumele ikhule.Ngemva kwezinsuku ezimbalwa, isampula yakho izobe isilungele ukuqhubeka nocwaningo.
