Momwe mungagwiritsire ntchito bwino ma pipettes ndi malangizo

Mofanana ndi wophika pogwiritsira ntchito mpeni, wasayansi amafunikira luso lopaka mapaipi. Wophika wodziwa bwino amatha kudula kaloti kukhala maliboni, akuwoneka kuti alibe lingaliro, koma sizimapweteka kukumbukira malangizo a mapaipi - ngakhale wasayansi wodziwa zambiri. Apa, akatswiri atatu amapereka malangizo awo apamwamba.

"Munthu ayenera kusamala kuti akhale ndi njira yoyenera pogawira madzi pamanja," akutero Magali Gaillard, woyang'anira wamkulu, oyang'anira ntchito, MLH Business Line, Gilson (Villiers-le-bel, France). "Zina mwazolakwika zapaipiti ndizogwirizana ndi kugwiritsa ntchito mosasamala kwa nsonga za pipette, kusinthasintha kwa nyimbo kapena nthawi, komanso kusagwira bwino kwa pipette."

Nthawi zina, wasayansi amasankha pipette yolakwika. Monga Rishi Porecha, woyang'anira malonda padziko lonse kuMvulaInstruments (Oakland, CA), akuti, "Zolakwa zina zomwe zimachitika pamipope zimaphatikizapo kusagwiritsa ntchito pipette yolondola pa ntchito inayake komanso kugwiritsa ntchito pipette yosamutsira mpweya kuti igwire madzi opanda madzi." Ndi madzi a viscous, pipette yosunthira bwino iyenera kugwiritsidwa ntchito nthawi zonse.

Musanayambe kutsata njira zina zapaipi, mfundo zina ziyenera kuganiziridwa. "Nthawi iliyonse ogwiritsa ntchito pipette akayamba ntchito tsikulo, ayenera kuganizira zomwe akuchita, zakumwa zomwe akugwiritsa ntchito, ndi zomwe amalakalaka asanasankhe pipette," adatero Porecha. "Zowonadi, palibe labu yomwe ili ndi zida zonse zomwe wogwiritsa ntchito angafune, koma ngati wogwiritsa ntchito ayang'ana zida zomwe zilipo mu labu ndi dipatimenti, atha kudziwa bwino zomwe ma pipette omwe alipo kuti agwiritse ntchito poyesa kapena ma pipette angafune kugula."

Zomwe zilipo mu pipettes zamasiku ano zimapitirira kuposa chipangizocho chokha. Kupita patsogolo kwa kayendetsedwe ka madzi kwapangitsa kuti ogwiritsa ntchito tsopano agwirizane ndi pipette yawo kumtambo. Ndi kulumikizana uku, wogwiritsa ntchito amatha kutsitsa ma protocol kapena kupanga zokonda. Deta ya mapaipi imatha kujambulidwa mumtambo, yomwe ndi njira imodzi yodziwira zolakwika zilizonse ndikuwongolera njira yapaipi, makamaka potsata kulondola komwe kumapitilira, kapena kusowa kwake.

Pokhala ndi zida zoyenera m'manja, vuto lotsatira ndikuwongolera masitepe.

Chinsinsi cha Chipambano

Ndi pipette yosuntha mpweya, njira zotsatirazi zimawonjezera mwayi woyeza molondola komanso mobwerezabwereza voliyumu inayake:

1. Ikani voliyumu pa pipette.
2. Tsitsani plunger.
3. Mizidwa nsongayo mpaka kuya koyenera, komwe kumatha kusiyanasiyana ndi pipette ndi nsonga, ndikulola kuti plunger ipite kumalo ake opuma.
4. Dikirani pafupifupi sekondi imodzi kuti madzi alowe munsonga.
5. Ikani pipette-yomwe imasungidwa pa madigiri 10-45-pakhoma la chipinda cholandirira, ndikugwetsa bwino plunger kumalo oyamba.
6. Dikirani sekondi imodzi ndiyeno tsitsani plunger poyimitsa kachiwiri.
7. Sungani nsonga pamwamba pa khoma la chombo kuti muchotse pipette.
8. Lolani plunger kubwerera pamalo ake opumira.
