Yiziphi izinyathelo zokuqapha ekulinganiseni i-pipette ne-burette?
Isilinganiso soketshezi esinembile sibalulekile ekuhlolweni kwaselabhorethri okuyimpumelelo, ikakhulukazi emikhakheni efana naleucwaningo lwe-biomedical, ikhemistri, futhiezemithi. Ukulinganiswa kwezinsimbi ezifanaama-pipettesfuthiama-burettekubalulekile ekuqinisekiseni ukunemba emsebenzini wakho. Noma ngabe wenza ama-titrations, udlulisa uketshezi, noma wenza ukuhlaziya amakhemikhali, ukulandela izinyathelo ezifanele ngesikhathi senqubo yokulinganisa kuqinisekisa imiphumela engaguquki, ethembekile.
At I-Ace Biomedical, siyakuqonda ukubaluleka kokusebenzisa amathuluzi ekhwalithi ephezulu ukulinganisa okunembile. Kulesi sihloko, sizokuqondisa kuzinqubo ezihamba phambili nezinyathelo ezibalulekile zokulinganisa ama-pipette nama-burette, ukuqinisekisa ukunemba okuphezulu nokusebenza.
Ukuze uhlole yethuamathiphu we-pipettenezinye izinsimbi ezinembayo, vakashela yethuikhasi lomkhiqizonoma ufunde okwengeziwe mayelana yethuamasevisi.
Kuyini Ukulinganisa Futhi Kungani Kubalulekile?
Ukulinganisa kusho inqubo yokuqinisekisa ukunemba kwamathuluzi aselabhorethri ngokuqhathanisa izilinganiso zawo namazinga aziwayo. Kuma-pipette nama-burette, lokhu kusho ukuqinisekisa ukuthi ivolumu abayikalayo noma abayikhiphayo ifana nenani elihlosiwe ngokuseduze ngangokunokwenzeka. Ngaphandle kokulinganisa okufanele, izilinganiso ezinganembile zingaholela emiphumeleni yokuhlola eyiphutha, yingakho ukulinganisa okuvamile kubalulekile.
Izinyathelo Zokuqaphela Ukulinganisa I-Pipette
I-pipette iyithuluzi elinembile elisetshenziselwa ukudlulisa umthamo othize woketshezi. Ukuqinisekisa ukunemba kwayo, landela lezi zinyathelo zokuphepha ezibalulekile ngesikhathi sokulinganisa:
1. Qinisekisa ukuthi i-Pipette Ihlanzekile
Ukuhlanzeka kubalulekile lapho ulinganisa i-pipette. Noma yiziphi izinsalela noma ukungcola okushiywe ngaphakathi kwe-pipette kusukela ekusetshenzisweni kwangaphambili kungashintsha ukulinganisa. Hlanza i-pipette yakho kahle nge-ejenti yokuhlanza efanelekile bese uyigeza ngayoamanzi distilledukuqinisekisa ukuthi awekho amakhemikhali ahlala isikhathi eside.
2. Cabanga Ngemiphumela Yezinga Lokushisa Emqulwini
Izinga lokushisa lithinta kakhulu umthamo woketshezi. Ukulinganisa kufanele kwenziwe ekushiseni okufanayo lapho kuzosetshenziswa i-pipette. Ama-pipettes amaningi alinganiswa ekushiseni okujwayelekile kwe20°C kuya ku-25°C. Uma izinga lokushisa loketshezi lihluka kulobu bubanzi, lingathinta ivolumu ekhishwayo. Qinisekisa ukuthi kokubili i-pipette ne-liquid zisezingeni lokushisa elilinganayo ukuze ugweme ukungezwani.
3. Susa Amabhamuza Omoya
Amabhamuza omoya ngaphakathi kwe-pipette angabangela amaphutha amakhulu okulinganisa. Ngaphambi kokulinganisa, qiniseka ukuthi awekho amabhamuza omoya emgqonyeni we-pipette noma ithiphu. Thepha i-pipette ngobumnene noma uyifake ukuze ususe noma yimuphi umoya ovalelwe. Lokhu kuzoqinisekisa ukuthi i-pipette ikhipha umthamo olungile woketshezi.
4. Sebenzisa Amasu Okuphatha Okufanelekile
Indlela ophatha ngayo i-pipette ngesikhathi sokulinganisa ingathinta ngokuqondile ukunemba kokulinganisa. Hlala ubambe i-pipette iqonde ukuze uqinisekise ukugeleza koketshezi okungaguquki. Ukutshekisa i-pipette kungaholela emaphutheni ngevolumu, ngakho-ke kubalulekile ukuyiphatha ngokusho kwemiyalelo yomkhiqizi.
5. Hlola Ukulimala Okubonakalayo
Ngaphambi kokulinganisa, hlola i-pipette ngomonakalo obonakalayo, njengokuqhekeka noma ukuvuza. Noma yimuphi umonakalo ungaholela ekulinganisweni okungalungile futhi kufanele ulungiswe ngokushesha. I-pipette eyonakele ayifanele ukulinganiswa okunembile, ngakho qiniseka ukuthi isesimweni esihle ngaphambi kokusetshenziswa.
6. Sebenzisa Uketshezi Lokulinganiswa Olwaziwa
Ukuze ulinganise i-pipette, sebenzisa uketshezi olunomthamo owaziwayo, njengeamanzi distilled. Linganisa uketshezi olukhishwa yi-pipette bese uqhathanisa nenani elilindelekile. Uma kukhona ukungafani, lungisa i-pipette ukuze ihambisane nevolumu efanele. Ukuhlola okujwayelekile kokulinganisa kuzosiza ukugcina ukunemba ngokuhamba kwesikhathi.
7. Gcina i-Pipette Ngokufanelekile
Isitoreji esifanele sibalulekile ekugcineni ukulinganiswa kwe-pipette yakho. Uma ingasetshenziswa, gcina i-pipette endaweni ephephile, eyomile, kude namakhemikhali anonya kanye nokulimala ngokomzimba. Ukusebenzisa icala lokuvikela noma umnikazi kuqinisekisa ukuthi i-pipette ihlala isesimweni esifanele ukuze isetshenziswe esikhathini esizayo.
Izinyathelo zokuqapha ukulinganisa i-Burette
I-burette ivamise ukusetshenziselwa ukukhipha amavolumu anembayo oketshezi ngesikhathi sokulinganisa noma okunye ukuhlola. Ukulinganisa okufanele kwe-burette kudinga ukunakwa ngokucophelela ngemininingwane. Ngezansi kunezinyathelo ezibalulekile okufanele uzilandele lapho ulinganisa i-burette:
1. Hlanza i-Burette Kahle
Njenge-pipette, i-burette kufanele ihlanzwe ngaphambi kokulinganisa. Noma iyiphi insalela evela ekuhlolweni kwangaphambilini ingaphazamisa ukulinganisa. Hlanza i-burette kahleamanzi distilledbese uyihlanza izikhathi eziningi ukuze ususe noma yikuphi ukungcola.
2. Hlola Amabhamuza Omoya
Amabhamuza omoya ngaphakathi kwe-burette noma umlomo wombhobho angaholela emaphutheni abalulekile okulinganisa. Ngaphambi kokulinganisa, qiniseka ukuthi awekho amabhamuza omoya. Gcwalisa i-burette ngamanzi, futhi uvumele noma yimuphi umoya ovaleleke ukuba ubaleke ngokuvula isitophucock, bese ukhipha uketshezi ukuze ukhiphe amabhamuza.
3. Zero the Burette
Ukunciphisa i-burette kuyisinyathelo esibalulekile ekulinganisweni. Lapho i-burette igcwele, qiniseka ukuthi indawo yokuqala isethweuphawu lweziro. Noma yikuphi ukuchezuka kusukela kuphoyinti elinguziro kungabangela ukungalungi esilinganisweni sevolumu ngesikhathi sokusetshenziswa. Njalo hlola ukuthi i-burette ikuziro ngaphambi kokuqala noma yikuphi ukuhlolwa noma inqubo yokulinganisa.
4. Sebenzisa Uketshezi Lokulinganiswa Olwaziwa
Njengama-pipettes, linganisa i-burette usebenzisa izindinganiso ezaziwayo zokunemba.Amanzi acwecweiwuketshezi olulungele le njongo ngoba inomthamo owaziwayo futhi kulula ukuyikala. Ngemva kokugcwalisa i-burette, khipha uketshezi ku-cylinder eneziqu bese uqhathanisa ivolumu nenani elilindelekile. Lungisa ukulinganiswa kwe-burette uma kutholakala ukungezwani.
5. Hlola I-Stopcock
Isitophucock silawula ukugeleza koketshezi olusuka ku-burette. Qinisekisa ukuthi isebenza kahle futhi ayivuzi. I-stopcock engasebenzi kahle ingabangela ukugeleza okungalingani, okuholela ekufundweni okungalungile. Shintsha noma lungisa isitophucock uma kunesidingo ukuze uqinisekise ukusebenza kahle.
6. Beka i-Burette Ngokuqondile
Ukuze ufinyelele izilinganiso ezinembile, qiniseka ukuthi i-burette imiswe mpo ngesikhathi sokulinganisa. Ukutshekisa i-burette kungabangela uketshezi ukuthi lugeleze ngokungalingani, okuholela emaphutheni. Sebenzisa isitendi se-burette ukuze ugcine i-burette isendaweni ngokuphephile futhi ugcine ukuqondanisa kwayo mpo ngesikhathi sokulinganisa.
7. Funda I-Meniscus Ngokufanelekile
Lapho ufunda izinga le-liquid ku-burette, qiniseka ukuthi ukhonaizinga lamehlonge-meniscus. I-meniscus iyindawo egobile yoketshezi, futhi ngoketshezi oluningi njengamanzi, ijika lizoba phansi. Funda iphuzu eliphansi kakhulu le-meniscus ukuze uqinisekise ukufundwa kwevolumu okunembile.
Ukulinganisa okuvamile kwakho kokubili ama-pipette nama-burette kubalulekile ukuze kuzuzwe izilinganiso ezinembile, ezinembile ekuhlolweni kwaselabhorethri. Ngokulandela izinyathelo zokuphepha ezingenhla, uqinisekisa ukuthi amathuluzi akho ahlinzeka ngedatha ethembekile isikhathi ngasinye. Ukuthi usebenza ngaphakathiucwaningo lwe-biomedical, ukuhlaziywa kwamakhemikhali, nomaukuhlolwa kwemithi, izilinganiso ezinembile zoketshezi zibalulekile empumelelweni yokuhlolwa kwakho.
At I-Ace Biomedical, siyakuqonda ukubaluleka kwamathuluzi aselabhorethri wekhwalithi ephezulu. Eyethu amathiphu we-pipette kanye neminye imikhiqizo yakhelwe ukuhlangabezana namazinga aphezulu okunemba, okuqinisekisa ukuthi ukuhlola kwakho kuletha imiphumela engcono kakhulu. Ukuze uthole ukwaziswa okwengeziwe, vakashela yethuikhasi eliyisiqalo, noma uma udinga usizo, khululekaXhumana nathi.
