Malangizo, monga consumables ntchito ndi pipettes, zambiri akhoza kugawidwa mu muyezo malangizo; nsonga zosefedwa;conductive fyuluta pipette malangizo, ndi zina.
1. Nsonga yokhazikika ndi nsonga yogwiritsidwa ntchito kwambiri. Pafupifupi ntchito zonse za pipetting zimatha kugwiritsa ntchito malangizo wamba, omwe ndi njira zotsika mtengo kwambiri.
2. nsonga yosefedwa ndiyomwe imagwiritsa ntchito kuti isatengeke ndi matenda osiyanasiyana ndipo imagwiritsidwa ntchito nthawi zambiri poyesera monga molekyulu ya biology, cytology, ndi virology.
3. Pamwamba pa nsonga yotsika kwambiri yakhala ndi chithandizo cha hydrophobic, chomwe chingathe kuchepetsa kutsekemera kwamadzimadzi otsika ndikusiya zotsalira zambiri pansonga.
PS: Nsonga yapakamwa yotakata ndiyabwino kuyamwa zinthu zowoneka bwino, ma genomic DNA, ndi madzi amtundu wama cell.
Momwe mungasankhire nsonga yabwino ya pipette?
Mawuwa tinganene kuti ndi oona koma osati oona. Nsonga yomwe ingakhoze kukwera pa pipette ikhoza kupanga dongosolo la pipetting ndi pipette kuti lizindikire ntchito ya pipetting, koma kodi izi ndizodalirika? Funso likufunika apa.
Malangizo a nsonga ya pipette
Ndiye ndi mfundo zochepa ziti zomwe nsonga yabwino iyenera kukhala nayo?
Nsonga yabwino imatengera kukhazikika, kutsika, ndipo mfundo yofunika kwambiri ndi kutsatsa;
1. Tiyeni tikambirane za taper poyamba: ngati kuli bwino, machesi ndi pipette ndi zabwino kwambiri.
2. Concentricity: Concentricity ndi ngati bwalo pakati pa nsonga ya nsonga ndi ulalo pakati pa nsonga ndi pipette ndi pakati chomwecho. Ngati sichiri pakati chomwecho, zikutanthauza kuti concentricity si bwino;
3. Pomaliza, chofunikira kwambiri ndi kutengeka kwathu: kuyamwa kumagwirizana ndi zinthu za nsonga. Ngati zinthu za nsonga sizili bwino, zidzakhudza kulondola kwa pipetting ndikupangitsa kuti madzi ambiri azisungidwa kapena kutchulidwa kuti akulendewera pakhoma, zomwe zimayambitsa zolakwika mu pipetting.
Kotero aliyense ayenera kumvetsera kwambiri mfundo zitatu zomwe zili pamwambazi posankha nsonga ya pipette. Mzere wa nsonga zoyipa umasiyanitsidwa bwino mosiyanasiyana! Mudzawona zosokoneza zoonekeratu, koma iyi ndi sitepe yofunika kwambiri posankha nsonga yabwino. Komanso, chonde dziwani kuyika kwa nsonga pa pipette ya njira imodzi ndi pipette yamitundu yambiri ndi yosiyana. Kwa kanjira kamodzi, ikani nsongayo molunjika pansonga ya pipette, kanikizani mopepuka, ndikutembenuza pang'ono kuti muyimitse. Kwa njira zambiri, njira zambiri za pipette ziyenera kugwirizanitsidwa ndi nsonga zambiri, zolowetsedwa pamakona, ndikugwedeza pang'ono mmbuyo ndi mtsogolo kuti zimangirire; Osabwereza kugunda pipette kuti mutsimikize kuti nsongayo ilibe mpweya.
Kuyankha funsoli kumafuna deta kuti ilankhule
1. Fananizani pipette ndi nsonga yoyesera ntchito.
2. Werengani kulondola kwa ntchito ya pipetting mutasintha kukhala voliyumu malinga ndi kuchuluka kwa madzi oyesera.
3. Chomwe tiyenera kusankha ndicho kukhala ndi nsonga yabwino. Ngati pipette ndi nsonga sizikugwirizana bwino, zikutanthauza kuti kumangika kwa nsonga ndi pipette sikungatsimikizidwe, zomwe zimapangitsa kuti zotsatira za ntchito iliyonse zikhale zosatheka kubereka.
