Zeziphi iindlela zokuthatha amanyathelo okulinganisa i-calibrate kunye ne-burette?
Ukulinganisa okuchanekileyo kubalulekile kubavavanyi belebhu ephumeleleyo, ngakumbi kwimihlaba efanaUphando lwe-biomedical, chemistry, kwayeamayeza. Ukulungelelanisa izixhobo ezifanaimibhobhokwayei-Buretteskubalulekile ukuba uqiniseke ukuba nomsebenzi wakho. Nokuba ngaba ukuqhuba izigidi, ulwelo oludlulayo, okanye ukwenziwa kokwenza ikhemikhali, ukulandela amanyathelo okhuseleko ngexesha lenkqubo yokulinganisa eqinisekisa ukuba indlela engaguqukiyo, enokuthenjwa.
At I-ACE BiOMedical, Siyakuqonda ukubaluleka kokusebenzisa izixhobo ezisemgangathweni eziphezulu zamanyathelo achanekileyo. Kweli nqaku, siza kukukhokela ngeyona ndlela ilungileyo kunye nezilumkiso eziphambili kumbhobho wokubhala kunye ne-burestts, ukuqinisekisa ukuchaneka okuphezulu kunye nokusebenza.
Ukuphonononga yethuIingcebiso zePipetteKwaye ezinye izixhobo zokuchaneka, ndwendwelaIphepha leMvelisookanye ufunde ngakumbi malunga neyethuiinkonzo.
Yintoni ukulinganisa kwaye kutheni kubalulekile?
Ukulinganisa kubhekisa kwinkqubo yokuqinisekisa ukuchaneka kwezixhobo zelebhu ngokuthelekisa imilinganiselo yazo ngemilinganiselo eyaziwayo. Kwimibhobho kunye ne-Burettes, oku kuthetha ukuqinisekisa ukuba ivolumu ilinganisa okanye i-dispeff ihambelana nexabiso elithile ngokusondeleyo kangangoko kunokwenzeka. Ngaphandle kokulinganisa ngokufanelekileyo, imilinganiselo engachanekanga kunokukhokelela kwiziphumo zovavanyo eziphosakeleyo, yiyo le nto ichasayo imfuneko.
Amanyathelo okhuseleko kwi-calibrate umbhobho
Umbhobho sisixhobo esichanekileyo esisetyenziselwa ukudlulisela ivolumu ethile yolwelo. Ukuqinisekisa ukuchaneka kwayo, landela olu lwakhiwo lubalulekileyo ngexesha lokulinganisa:
1. Qinisekisa ukuba i-pipette icocekile
Ukucoceka kubalulekile xa ulawula umbhobho. Nawaphi na intsalela okanye intsasazo eshiyekileyo ngaphakathi kombhobho ukusuka ekusebenziseni kwangaphambili kunokutshintsha umlinganiso. Coca Pipette yakho kakuhle kunye nearhente efanelekileyo yokucoca kwaye ihlezemamanzi amisiweUkuqinisekisa ukuba akukho zikhemikhali zokulala.
2. Jonga iziphumo zobushushu kwivolumu
Iqondo lokushisa lichaphazela kakhulu ivolumu yolwelo. Ukulinganisa kufuneka kwenziwe kwiqondo lobushushu olufanayo apho isetyenzisiwe umbhobho. Uninzi lweepayiti zilungelelaniswe kwiqondo elisezantsi leI-20 ° C ukuya kwi-25 ° C. Ukuba amaqondo obushushu olwelo ahluka kolu luhlu, inokuchaphazela ivolumu esetyenziswe. Qiniseka ukuba zombini imipu kunye nolwelo zikwiqondo elingaguqukiyo ukuphepha ukungangqinelani.
3. Susa iiblubhu zomoya
Iibhubhu zomoya ngaphakathi kombhobho zinokubangela iimpazamo ezibalulekileyo. Phambi kokuba ulungelelanise, qinisekisa ukuba akukho bhabhu yomoya kumngxunya we-pipette okanye inqaku. Thepha ipipette ngobumnene okanye iphambili ukuba isuse nawuphi na umoya obanjiweyo. Oku kuyakuqinisekisa ukuba i-pipette ihambisa ivolumu efanelekileyo yolwelo.
4. Sebenzisa iindlela ezifanelekileyo zokuphatha
Indlela owuphatha ngayo umbhobho ngexesha lokulinganisa inokufumana ifuthe ngqo ukuchaneka kwemilinganiselo. Soloko ubamba umbhobho nkqo ukuqinisekisa ukuhamba kwamanzi okungaguqukiyo. Ukutsala umbhobho kunokukhokelela kwiimpazamo kwivolumu, kuya kuba yimfuneko ukuyiphatha ngokwemiyalelo yomenzi.
I-5. Jonga umonakalo obonakalayo
Phambi kokuba ulungelelanise, jonga umbhobho womonakalo obonakalayo, onjengokuqhekeka okanye ukuvuza. Nawuphi na umonakalo unokukhokelela kumanyathelo achanekileyo kwaye kufuneka ilungiswe kwangoko. Umbhobho owonakalisiweyo awuyifanelekanga kumlinganiso ochanekileyo, qinisekisa ukuba ukwimeko elungileyo ngaphambi kokusetyenziswa.
6. Sebenzisa ulwelo oluziwayo
Ukulungelelanisa umbhobho, sebenzisa ulwelo ngevolumu eyaziwayo, njengemamanzi amisiwe. Linganisa ulwelo luye lwasasazwa ngumbhobho kwaye uthelekise kwixabiso elilindelekileyo. Ukuba kukho nakuphi na ukungangqinelani, lungisa umbhobho wokutshatisa ivolumu efanelekileyo. Iitsheki rhoqo zokulinganisa ziya kunceda ukugcina ukulungisa ngokuhamba kwexesha.
7. Gcina i-pipette ngokuchanekileyo
Ukugcinwa ngokufanelekileyo kubalulekile ekugcineni ulungelelwaniso lwepatte. Xa ungasetyenziswanga, gcina umbhobho kwindawo ekhuselekileyo, eyomileyo, kude neekhemikhali ezinzima kunye nomonakalo womzimba. Ukusebenzisa icala lokukhusela okanye umniniyo uqinisekisa ukuba umbhobho uhlala kwimeko efanelekileyo yokusetyenziswa kwixesha elizayo.
Amanyathelo okhuseleko kwi-calibrate i-burette
I-Burette ihlala isetyenziselwa ukusasaza imiqulu yolwelo kulwelo ngexesha lezibalo okanye ezinye iimvavanyo. Ukulinganiswa ngokufanelekileyo kwe-Burette kufuna ukuqwalaselwa ngononophelo. Apha ngezantsi kukho iindlela eziphambili zokulandela xa ubhala i-burette:
1. Coca i-Burette ngokucokisekileyo
Njengombhobho, i-curitte kufuneka icocwe ngaphambi kokukwazi. Nawaphi na intsalela kuvavanyo lwangaphambili lunokuphazamisa umlinganiso. Coca i-Burette ngokucokisekileyomamanzi amisiweKwaye hlamba amaxesha amaninzi ukususa nayiphi na into engcolisayo.
I-2. Jonga iiblubhu zomoya
Iibhubhu zomoya ngaphakathi kwe-Burette okanye i-nozzle inokukhokelela kwiimpazamo ezibalulekileyo. Ngaphambi kokuzingca, qinisekisa ukuba akukho bhabble moya. Gcwalisa i-Burette ngamanzi, kwaye uvumele naluphi na umoya obanjiweyo wokubaleka ngokuvula indawo yokumisa, emva koko usasaze ulwelo ukuze ucoce iibhubhu.
I-3. Zero i-Burette
Ukuzimla kwe-burette linyathelo elibalulekileyo ekulinganeni. Xa i-Burette igcwalisiwe, qiniseka ukuba indawo yokuqala isetiwe kwiI-zero phawu. Nakuphi na ukuphambuka kwinqaku le-zero kunokubangela ukungachaneki kwimilinganiselo yevolumu ngexesha lokusetyenziswa. Soloko ujonga i-Burette ikwi-zero ngaphambi kokuqala nayiphi na inkqubo okanye yenkqubo yokulinganisa.
4. Sebenzisa ulwelo oluziwayo
Njengombhobho, bhala i-burette usebenzisa imigangatho eyaziwayo yokuchaneka.Mamanzi amisiweNgulwelo olulungileyo ukulungiselela le njongo kuba inobuqili owaziwayo kwaye kulula ukuyilinganisa. Emva kokugcwalisa i-Burette, ukuhambisa i-windows kwi-cylinder ephumelele kwaye uthelekise ivolumu kwixabiso elilindelekileyo. Lungisa i-Burette calibration ukuba ifunyenwe ingangqinelani.
I-5. Jonga i-Stopkock
I-Stopkock ilawula ukuhamba kolwelo kwi-Burette. Qinisekisa ukuba kuyasebenza kakuhle kwaye simahla ekuvuzelweni. Indawo yokumisa ukungasebenzi kakuhle inokubangela ukuhamba okungalinganiyo, kubangela ukufundiswa okungachanekanga. Faka endaweni okanye ulungise i-Stopcock ukuba iyimfuneko ukuqinisekisa ukusebenza kakuhle.
6. Beka i-Burette ngokuthe nkqo
Ukufezekisa imilinganiselo echanekileyo, qiniseka ukuba i-Burette ibekwe ngokuthe nkqo ngexesha lokulinganisa. Ukucofa i-Burette kunokubangela ulwelo ukuba luhambe ngendlela engacocekanga, elikhokelela kwiimpazamo. Sebenzisa i-Burette Ima ukuze igcine i-Burette ngokukhuselekileyo kwaye igcinwe ngokungqinelana okuthe nkqo ngexesha lokulinganisa.
7. Funda iMentiscus ngokuchanekileyo
Xa ufunda inqanaba lolwelo kwi-Burette, qinisekisa ukuba ukhonainqanaba lamehlokunye neMentiscus. Imeyiristy luphawu olugobileyo lolwelo, kwaye ngobuqhetseba obuninzi njengamanzi, ijika liya kuba phantsi. Funda eyona ndawo iphantsi yeMentiscus ukuqinisekisa ukufundwa kwevolumu ngokuchanekileyo.
Ukulinganisa rhoqo kombhobho kunye ne-Buretsttes kubalulekile ekufezekiseni imilinganiselo echanekileyo, echanekileyo kuvavanyo lwelebhu. Ngokulandela la manyathelo angasentla, uqinisekisa ukuba izixhobo zakho zibonelela ngedatha ethembekileyo ngexesha ngalinye. Nokuba ukusebenza ngaphakathiUphando lwe-biomedical, uhlalutyo lweekhemikhali, okanyeUvavanyo lwamachiza, imilinganiselo ye-flule echanekileyo ibalulekile kwimpumelelo yovavanyo lwakho.
At I-ACE BiOMedical, siyakuqonda ukubaluleka kwezixhobo zelebhu. Bethu Iingcebiso zePipette Kwaye ezinye iimveliso zenzelwe ukuhlangabezana nemigangatho ephezulu yokuchaneka, ekuqinisekiseni iimvavanyo zakho zizisa iziphumo ezilungileyo. Ngolwazi oluthe kratya, ndwendwelaiphepha lasekhaya, okanye ukuba ufuna uncedo, zive ukhululekile ukubaQhagamshelana nathi.
