Yakarurama nzira yekushandisa uye matanho e serological pipette
Iyo serological pipette, inozivikanwawo sepipette inoraswa, inonyanya kushandiswa kuyera nemazvo imwe vhoriyamu yemvura, iyo inofanirwa kushandiswa pamwe chete nepipette yakakodzera.Pipette mudziyo wekuyera unoshandiswa kufambisa nemazvo imwe vhoriyamu yemhinduro.Iyo pipette isimbi yekuyeresa, iyo inoshandiswa chete kuyera huwandu hwemhinduro yainoburitsa.Ichubhu refu uye nhete ine kuwedzera kukuru pakati.Mugumo waro wezasi uri muchimiro chemuromo wakapinza, uye mutsipa wepombi wepamusoro wakanyorwa nemutsara wekumaka, iyo chiratidzo chehuwandu chaihwo hunofanira kutamiswa.
Yakarurama nzira yekushandisa uye matanho e serological pipette
1. Usati washandisa:Paunenge uchishandisa pipette, tanga watarisa papipette mark, kunyatsoita nhanho, scale mark position, nezvimwe.
2. Aspiration:Bata mucheto wepamusoro wepipette nechigunwe chepakati nepakati cheruoko rwako rworudyi, uye isa muromo wezasi wepipette mumushonga unoyamwa.Iko kupinza hakufanirwe kuve kwakadzika kana kudzika zvakanyanya, kazhinji 10 ~ 20mm.Kana ikanyanya kudzika, inokonzeresa kuyamwa.Aspiration yemhinduro mubhora rekugezesa nzeve ichasvibisa mhinduro.Kana yakanyanyisa kudzika, inonamatira yakawandisa mhinduro kunze kwechubhu.Tora bhora rekushambidza nzeve neruoko rworuboshwe, ribatanidze kumuromo wepamusoro wechubhu uye zvishoma nezvishoma inhale mhinduro.Kutanga inhale inenge 1/3 yehuwandu hwechubhu.Dzvanya muromo wechubhu nechigunwe cheruoko rwerudyi, wobura kunze, wochibata wakachinjika, wotenderedza chubhu kuita kuti mhinduro ibatane nechikamu chiri pamusoro pekero kuti itsive mvura pamadziro emukati.Zvadaro bvisa mhinduro kubva pamuromo wezasi wechubhu uye uirase.Mushure mekudzokorora kushambidza katatu, unogona kutora mhinduro kune inenge 5mm pamusoro pechiyero.Pakarepo dzvanya muromo wechubhu nechigunwe cherudyi.
3. Rongedza mwero wemvura: simudza pipette kumusoro uye kure nechiyero chemvura, pukuta mvura iri pamadziro ekunze kwepipette nepepa refirita, kuguma kwechubhu kunotsamira pamadziro emukati wemudziyo wekugadzirisa, mutumbi wechubhu unoramba wakamira, zvishoma kuzorora. chigunwe chemunwe kuita sarudzo muchubhu inoyerera zvishoma nezvishoma kubva mumuromo wezasi, kusvikira pasi pe meniscus yemhinduro iri tangent kusvika pakumaka, uye pakarepo shandisa muromo wechubhu nechigunwe.Bvisa donho remvura pamadziro, ribvise kubva pipette, uye uiise mumudziyo unogamuchira mhinduro.
4. Kubviswa kwemhinduro:Kana mudziyo wekugamuchira mhinduro iri conical flask, iyo conical flask inofanira kurerekera 30 °.Iyo pipette inoraswa inofanira kuva yakatwasuka.Mugumo wezasi wechubhu unofanirwa kuva pedyo nemadziro emukati econical flask.Sunungura chigunwe uye rega mhinduro yacho ichiyerera zvishoma nezvishoma ichidzika nemadziro ebhodhoro.Kana iyo nhanho yemvura inodonha kusvika kumusoro wekubuda, chubhu inobata mukati memadziro ebhodhoro kwemasekonzi gumi nemashanu, wozobvisa pipette.Chinhu chiduku chekugadzirisa chakasara pamagumo echubhu haifaniri kumanikidzirwa kubuda kunze, Nokuti huwandu hwekugadzirisa hwakachengetwa pamagumo hwakatorwa.
