Ndi njira ziti zodzitetezera pakuwongolera pipette ndi burette?
Muyezo wolondola wamadzimadzi ndi wofunikira pakuyesa kopambana kwa labotale, makamaka m'magawo ngatikafukufuku wamankhwala, chemistry,ndimankhwala. Kuwongolera zida mongamapaipindimabatirendizofunikira kwambiri pakuwonetsetsa kuti ntchito yanu ili yolondola. Kaya mukupanga ma titration, kusamutsa zakumwa, kapena kusanthula mankhwala, kutsatira njira zoyenera pakuwongolera kumatsimikizira zotsatira zokhazikika, zodalirika.
At Ace Biomedical, timamvetsetsa kufunikira kogwiritsa ntchito zida zapamwamba poyezera molondola. M'nkhaniyi, tidzakuwongolerani njira zabwino kwambiri komanso njira zazikulu zodzitetezera pakuwongolera ma pipette ndi ma burette, kuwonetsetsa kulondola komanso magwiridwe antchito.
Kuti tifufuze zathumalangizo a pipettendi zida zina zolondola, pitani kwathutsamba mankhwalakapena kudziwa zambiri za wathuntchito.
Kodi Calibration Ndi Chiyani Ndipo Chifukwa Chiyani Ndi Yofunika?
Calibration imatanthawuza njira yotsimikizira kulondola kwa zida za labotale poyerekeza miyeso yake ndi miyezo yodziwika. Kwa ma pipette ndi ma burettes, izi zikutanthauza kuonetsetsa kuti voliyumu yomwe amayezera kapena kugawa ikugwirizana ndi ndalama zomwe akufunikira kwambiri. Popanda kulinganiza koyenera, miyeso yolakwika imatha kubweretsa zotsatira zolakwika, chifukwa chake kuwongolera pafupipafupi ndikofunikira.
Njira Zodzitetezera Poyesa Pipette
Pipette ndi chida chodziwika bwino chomwe chimagwiritsidwa ntchito kusamutsa kuchuluka kwamadzimadzi. Kuti muwonetsetse kulondola kwake, tsatirani njira zofunika izi pakuwongolera:
1. Onetsetsani kuti Pipette Ndi Yoyera
Ukhondo ndi wofunika kwambiri pokonza pipette. Zotsalira zilizonse kapena zowonongeka zomwe zatsala mkati mwa pipette kuchokera ku ntchito zam'mbuyo zimatha kusintha muyeso. Sambani pipette yanu bwino ndi woyeretsa woyenera ndikutsuka nayomadzi osungunukakuonetsetsa kuti palibe mankhwala omwe akuchedwa.
2. Ganizirani za Kutentha Kumakhudza Voliyumu
Kutentha kumakhudza kwambiri kuchuluka kwamadzimadzi. Kuwongolera kuyenera kuchitika pa kutentha komweko komwe pipette idzagwiritsidwa ntchito. Ambiri pipettes calibrated pa kutentha muyezo wa20 ° C mpaka 25 ° C. Ngati kutentha kwamadzimadzi kumasiyana ndi izi, kungakhudze voliyumu yomwe imaperekedwa. Onetsetsani kuti pipette ndi madzi zili pa kutentha kosasinthasintha kuti mupewe kusagwirizana.
3. Chotsani Mivi ya Air
Kuphulika kwa mpweya mkati mwa pipette kungayambitse zolakwika zazikulu za kuyeza. Musanayambe kusanja, onetsetsani kuti palibe thovu la mpweya mu mbiya ya pipette kapena nsonga. Dinani pipette pang'onopang'ono kapena yang'anani kuti muchotse mpweya uliwonse wotsekedwa. Izi zidzaonetsetsa kuti pipette imatulutsa madzi okwanira.
4. Gwiritsani Ntchito Njira Zoyenera Zogwirira Ntchito
Momwe mumagwiritsira ntchito pipette panthawi ya calibration imatha kukhudza kulondola kwa kuyeza. Nthawi zonse gwirani pipette molunjika kuti muwonetsetse kuti madzi akuyenda. Kupendekeka kwa pipette kungayambitse zolakwika mu voliyumu, kotero ndikofunikira kuigwira molingana ndi malangizo a wopanga.
5. Yang'anani Zowonongeka Zowoneka
Musanayambe kuwongolera, fufuzani pipette kuti muwone kuwonongeka, monga ming'alu kapena kutayikira. Kuwonongeka kulikonse kungayambitse miyeso yolakwika ndipo iyenera kuthetsedwa mwamsanga. Pipette yowonongeka si yoyenera kuyeza molondola, choncho onetsetsani kuti ili bwino musanagwiritse ntchito.
6. Gwiritsani Ntchito Zamadzimadzi Zomwe Zikudziwika
Kuti muyese pipette, gwiritsani ntchito madzi omwe ali ndi voliyumu yodziwika, mongamadzi osungunuka. Yezerani madzi omwe amaperekedwa ndi pipette ndikufanizira ndi mtengo womwe ukuyembekezeka. Ngati pali kusiyana kulikonse, sinthani pipette kuti igwirizane ndi voliyumu yoyenera. Kuwunika kokhazikika kwanthawi zonse kumathandizira kusunga zolondola pakapita nthawi.
7. Sungani Pipette Moyenera
Kusungirako koyenera ndikofunikira kuti musunge mayendedwe a pipette. Musanagwiritse ntchito, sungani pipette pamalo otetezeka, owuma, kutali ndi mankhwala oopsa komanso kuwonongeka kwa thupi. Kugwiritsira ntchito chotetezera kapena chogwiritsira ntchito kumatsimikizira kuti pipette imakhalabe yabwino kuti igwiritsidwe ntchito mtsogolo.
Njira Zodzitetezera Kukonzekera kwa Burette
A freette amagwiritsidwa ntchito popereka kuchuluka kwamadzimadzi panthawi yoyeserera kapena kuyesa kwina. Kuwongolera bwino kwa burette kumafuna kusamala mwatsatanetsatane. M'munsimu muli njira zodzitetezera zomwe muyenera kuzitsatira pokonzekera burette:
1. Tsukani Burette Mokwanira
Monga pipette, burette iyenera kutsukidwa musanayesedwe. Zotsalira zilizonse zoyeserera zam'mbuyomu zitha kusokoneza muyeso. Sambani burette ndimadzi osungunukandipo muzimutsuka kangapo kuti muchotse zodetsa zilizonse.
2. Yang'anani Mphepo za Air
Kuphulika kwa mpweya mkati mwa burette kapena nozzle kungayambitse zolakwika zazikulu. Musanasinthire, onetsetsani kuti palibe thovu la mpweya. Lembani burette ndi madzi, ndipo lolani mpweya uliwonse wotsekeredwa kuthawa potsegula stopcock, kenaka perekani madziwo kuti mutulutse thovu.
3. Zero the Burette
Zeroing the burette ndi gawo lofunikira pakuwongolera. Pamene burette yadzazidwa, onetsetsani kuti poyambira yakhazikitsidwazero chizindikiro. Kupatuka kulikonse kuchokera pa zero kungayambitse zolakwika pakuyezetsa kwa voliyumu mukamagwiritsa ntchito. Nthawi zonse fufuzani kuti burette ili pa zero musanayambe kuyesa kapena kuyesa.
4. Gwiritsani Ntchito Zamadzimadzi Zomwe Zikudziwika
Monga momwe zilili ndi pipettes, sungani burette pogwiritsa ntchito miyezo yodziwika bwino.Madzi osungunukandi madzi abwino pachifukwa ichi chifukwa ali ndi kachulukidwe kodziwika komanso kosavuta kuyeza. Mukadzaza burette, perekani madziwo mu silinda yomaliza ndikuyerekeza voliyumu ndi mtengo womwe ukuyembekezeka. Sinthani ma calibration a burette ngati zosagwirizana zipezeka.
5. Yang'anani Stopcock
Stopcock imayang'anira kutuluka kwamadzi kuchokera ku burette. Onetsetsani kuti ikugwira ntchito moyenera komanso yopanda kutayikira. Stopcock yosagwira bwino imatha kuchititsa kuyenda mosagwirizana, zomwe zimapangitsa kuti pakhale kuwerenga kolakwika. Bwezerani kapena konza stopcock ngati kuli kofunikira kuti muwonetsetse kuti ikuyenda bwino.
6. Ikani Burette Molunjika
Kuti mukwaniritse miyeso yolondola, onetsetsani kuti burette yayimitsidwa molunjika panthawi yoyeserera. Kupendekeka kwa burette kungayambitse madzi kuyenda mosagwirizana, zomwe zimayambitsa zolakwika. Gwiritsani ntchito choyimira cha burette kuti musunge burette motetezeka ndikusunga mawonekedwe ake ofukula pakuwongolera.
7. Werengani Meniscus Molondola
Mukamawerenga mulingo wamadzimadzi mu burette, onetsetsani kuti mulimulingo wamasondi meniscus. Meniscus ndi malo opindika amadzimadzi, ndipo pamadzi ambiri ngati madzi, mphunoyo imakhala pansi. Werengani malo otsika kwambiri a meniscus kuti mutsimikize kuwerengera voliyumu yolondola.
Kuwongolera pafupipafupi kwa ma pipette ndi ma burette ndikofunikira kuti mukwaniritse miyeso yolondola, yolondola pamayesero a labotale. Potsatira njira zomwe zili pamwambazi, mumaonetsetsa kuti zida zanu zimapereka deta yodalirika nthawi iliyonse. Kaya mukugwira ntchitokafukufuku wamankhwala, kusanthula mankhwala, kapenakuyezetsa mankhwala, miyeso yolondola yamadzimadzi ndiyofunikira kuti zoyeserera zanu zitheke.
At Ace Biomedical, timamvetsetsa tanthauzo la zida za labotale zapamwamba kwambiri. Zathu malangizo a pipette ndi zinthu zina zidapangidwa kuti zikwaniritse miyezo yapamwamba kwambiri yolondola, kuwonetsetsa kuti zoyeserera zanu zimabweretsa zotsatira zabwino kwambiri. Kuti mudziwe zambiri, pitani kwathutsamba lofikira, kapena ngati mukufuna thandizo, khalani omasukaLumikizanani nafe.
