I-Chemistry lisebe lezesayensi ekufuneka sibeke kulo uninzi lwezinto ezifunyanisiweyo kunye nenkqubela phambili ephunyezwe ngabantu, njengohlanga. Enkosi kweli sebe elithile, kuye kwenzeka ukuba kufunyanwe kwaye kudweliswe zonke ezo zinto sizisebenzisa mihla le. Ukongeza koku, enkosi kwikhemistri, inkqubela phambili yenziwe kwilizwe lezamayeza, iiplastikhi kunye nokutya.
Nangona kunjalo, nangona sinokwazi ngayo yonke into chemistry isenzele, kunqabile ukuba sime kwaye sithathe ixesha lokukhumbula, hayi inzululwazi kuphela, kodwa ezo zinto zisivumela ukuba senze olo vavanyo lusisebenzele kakuhle.
Iflaski yeKitasato yenye yezi zinto zaselabhoratri kunqabile ukuba kuthethwe ngazo, kwaye kule posi siza kunxiba idyasi yethu emhlophe, singene elabhoratri kwaye sifumanise ukuba yeyiphi na into enokusetyenziswa ngeFlask Kitasato.
Yintoni iflask Kitasato?
Ibhotile yaseKitasato, okanye ebizwa nje ngokuba yikitasato, yibhotile ebandakanyiweyo phakathi kweglasi yelabhoratri. Yiyo, kwinkcazo yayo esisiseko, iflask ye-Erlenmeyer apho kuye kongezwa ityhubhu encinci yamandla okanye umbhobho wecala. Isetyenziswe kuvavanyo lwamanzi, njengokucoca ulwelo, ukuqokelela irhasi, ukucoca amanzi, phakathi kwabanye.
Imbali yeflask kitasato
Ukuyilwa kwale flask kubuyele kwiminyaka engaphezulu kwekhulu eyadlulayo, ngelaxesha ingcali yebacteria uShibasaburo Kitasato wancedisa kunye namaxesha amaninzi ekufumanekeni kwezinto ezosulelayo kunye nokupheliswa kwazo okwalandelayo. Iziphumo zakhe ziyaziwa kuphando malunga nesibetho se-bubonic, owayengowokuqala ukufumana ngempumelelo i-arhente echaphazelayo, kwi-dysentery, diphtheria, phakathi kwabanye.
Ngokugxila kwisebe lekhemistri elinikezelwe kunyango, wakwazi ukuphumelela ngempumelelo iflask enegama lakhe namhlanje, kwaye isetyenziswa ngamaxesha athile kwimisebenzi yerhasi kunye nesisombululo, njengoko ivumela ulwelo olululwayo ngokulula, ukongeza ekwenzeni ukuvuza okungafunekiyo.
Iimpawu eziphambili
Iflaski yeKitasato, ehlala isetyenziswa kuzo zombini iilabhoratri zamachiza kunye nezonyango, isadidekile nanamhlanje neflask ye-Erlenmeyer, ikakhulu ngenxa yobume bayo.
Le flask inobume obudibeneyo kunye nentamo evulekileyo, umlomo otyebileyo wokudlula kwezinto, kunye nomphetho omncinci ukunqanda ukuchitheka; Ngamafutshane iyafana kakhulu neflask ye-Erlenmeyer. Iglasi eyenziwe ngayo, nangona kunjalo, kufuneka ibe nkulu kakhulu kuba le flask kufuneka ikwazi ukumelana noxinzelelo oluphezulu.
Olona phawu lwalo lubonakalayo yityhubhu encinci ephuma kwelinye icala layo, kwelona bhotile lincinci. Le tyhubhu izalisekisa imisebenzi enomdla, kuba igesi eya kwahluka kwenye indawo iya kudlula kuyo ukuze ifundwe ngokwahlukeneyo.
Ukusetyenziswa kwale flask
Njengoko sele kukhankanyiwe, iflask yaseKitasato yenzelwe, okanye isetyenziselwa ngokukodwa, kwizifundo ezinxulumene namanzi. Nangona kunjalo, Ubungqindilili bayo benza ukuba kuhlolwe ezinye iindidi zeegesi, kuba ixhasa amanqanaba oxinzelelo ahlukeneyo. Ukusetyenziswa kwayo kuyahlukahluka kwilabhoratri. Nazi izinto eziqhelekileyo:
Ukuphazamiseka
I-Distillation yinkqubo ekufunwa ngayo ukukhupha igesi kumxube oye waba yirhasi emva kokuba ngaphambili yayiyiglasi okanye eyomeleleyo. Ngenxa yokuphendula iikhompawundi ezahluliweyo, kunye nokusebenza negesi kufuneka ichithwe ukuze kushiye intsalela eqinileyo okanye yolwelo ngasemva. Ndiyabulela kule ndlela, into eguqukayo inokwahlulwa kwezo zingazinzanga, kwaye yenziwa ngokwahlula irhasi ngomphunga kwaye emva koko ukubuyela emva kwayo.
Imiqulu yeShift
Kule ndlela, ivolumu yento engafakwanga ifundwa ukuze ichongwe ngokujonga indlela esebenza ngayo kulwelo. Le ndlela ibalasele kwaye isetyenziswa rhoqo kufundo lwevolidi eqinileyo.
Kuba kunokuthiwa into iya kuba nomthamo olingana nendawo ekuyo, ngokususa umthamo wolwelo esinokuthi, kunye nokubala okulula kwemathematics, ukumisela ivolumu yento ekuthethwa ngayo.
Ukucoca i-vacuum
Ngale ndlela, into efunwayo kukwahlula umxube owenziwe ngezinto ezingamanzi kunye nezinto eziqinileyo. Into oyifunayo kukucoca ezi zinto usebenzisa impompo yokudibanisa kunye nefanele yeBüchner, ekufuneka ibekwe kuyo isihluzi. Le faneli iya kubekwa ngaphezulu kwiflaski yeKitasato.
Le ndlela isetyenziswa xa ufuna ukufumana into eqinileyo yekhompawundi, ngakumbi xa ikhompawundi ekuthethwa ngayo ine-viscosity ephezulu, okanye xa izinto eziqinileyo zincinci kakhulu.
Izinto eziluncedo ekusebenziseni le flask
Zininzi izibonelelo ezichaphazelekayo ekusebenziseni le flask. Apha siza kudwelisa ezimbalwa.
- Olona loncedo lucacileyo kukuba, ngenxa yetyhubhu yaso, isenza sikwazi ukwahlula izinto zegesi ezazixutywe ngaphambili kunye nezinto eziqinileyo okanye zolwelo.
- Ikwasinika uncedo olulungileyo xa uphatha ulwelo, kuba umda omxinwa wokuvula kwayo okuphezulu uvumela into leyo ukuba igcinwe icoceke kangangoko xa isebenza nayo. Ngale ndlela, ukukhutshwa komphunga kompompo okanye ukungcoliseka kwayo ngabasebenzi bangaphandle kuyathintelwa.
- Ngaphakathi kule flask iikhompawundi zinokuvuselelwa ngokukuko ngakumbi nangaphakathi kwebeaker, enesakhiwo esibanzi, nangona iluncedo kwiimeko ezininzi, ikwafuna ukuchitheka.
- Le bhaskiti ikwasivumela ukuphatha kakuhle into esisebenza nayo, kuba ngokungafaniyo nezinye iiflask zaselebhu, iyasivumela ukuba sishiye izinto ziphumlile ngaphandle komngcipheko wokuchitheka komxube
