Micropipette mwina ndi chida chogwiritsidwa ntchito kwambiri mu labotale.Amagwiritsidwa ntchito ndi asayansi m'magawo osiyanasiyana kuphatikiza maphunziro, zipatala ndi ma labotale azamalamulo komanso kupanga mankhwala ndi katemera kuti asamutsire madzi amchere, ochepa kwambiri.
Ngakhale zingakhale zokwiyitsa komanso zokhumudwitsa kuwona thovu la mpweya pansonga ya pipette yotayika ngati silinawonedwe kapena kunyalanyazidwa, zitha kukhudza kwambiri kudalirika komanso kuchulukitsa kwa zotsatira.
Nkhani yabwino ndiyakuti pali njira zina zosavuta zomwe mungachite kuti mupewe kuphulika kwa mpweya, ndikuwongolera magwiridwe antchito a labu, kukhutitsidwa ndi oyendetsa komanso kulondola komanso kulondola kwazotsatira.
Pansipa, tikuwunika zotsatira zopeza kuwira kwa mpweya mu nsonga ya pipette ndi zomwe muyenera kuchita kenako.
Zotsatira za Bubbles muPipette Tip
Ngakhale mutagwiritsa ntchito zolondola kwambiri, pamwamba pazigawo, zosamalidwa bwino, zogwiritsidwa ntchito komanso zoyendetsedwa bwino, kudalirika kwa zotsatira zanu kungakhudzidwe ndi zolakwika za labu.Pamene thovu kulowa munsongaikhoza kukhala ndi zotsatira zingapo.
● Wogwiritsa ntchito akawona kuwira kwa mpweya ayenera kuthera nthawi kuti apereke madziwo moyenerera, tulutsani nsongayo ndikuyambanso ntchitoyo.
● Mavuvu a mpweya osazindikirika angapangitse kusamutsa kwa voliyumu yotsika, motero kumasintha kusakanikirana kwamachitidwe komwe kumapangitsa kuyesa kulephera komanso zotsatira zokayikitsa kapena zosadalirika.
Zotsatirazi zitha kukhala ndi zotsatira zingapo (1).
● Kuchepa kwa Labu Logwira Ntchito - Mayesero ndi zoyesa ziyenera kubwerezedwa, kubweretsa ndalama zogwirira ntchito ndi zakuthupi, zomwe zingakhale zokulirapo.
● Zotsatira Zokayikitsa Kapena Zolakwika - Ngati zotsatira zolakwika zatulutsidwa pangakhale zotsatira zoopsa kwambiri kuphatikizapo kusazindikira bwino komanso zotsatira za odwala.
● Kuchotsa Zolemba Pamanja - Ngati anzanu akulephera kubwereza zotsatira zanu chifukwa cha kuphulika kwa mpweya kumapangitsa kuti mapepala a zotsatira zolakwika achotsedwe.
Njira Zabwino Zopewera Kuphulika kwa Mpweya
Nthawi zambiri, thovu la mpweya mu nsonga za pipette zimachitika chifukwa cha zolakwika za opareshoni.Kusaphunzitsidwa bwino kapena kutopa nthawi zambiri ndiye vuto lalikulu.
Kupaka mapaipi ndi ntchito yaluso yomwe imafunikira chidwi cha 110%, kuphunzitsidwa koyenera komanso kuchita bwino kuti mupeze zotsatira zokhazikika komanso zolondola.
Ngakhale pali zinthu zingapo zomwe mungachite kuti muchepetse zolakwika zapaipi, m'munsimu tawunikira njira zabwino zomwe zingagwiritsidwe ntchito kupewa kutulutsa mpweya mumalangizo a pipette.
