Chilichonse Chimene Mumafuna Kudziwa Zokhudza Malangizo a Pipette Ndi Zambiri

 

Ndizovuta kukhulupirira kuti malangizo osavuta, opangidwa ndi pulasitiki omwe ali ndi mkate ndi batala wa biology ya maselo, chemistry komanso zamankhwala. Ndiko kulondola, tikulankhula za malangizo a pipette. Malangizo awa amapanga njira yodalirika komanso yolondola yopopera. Malangizo a pipette amabwera m'mitundu itatu kuphatikiza yopanda wosabala, yopangira chosawilitsidwa ndi zosefera. 

Mtundu wa pipette womwe umagwiritsidwa ntchito kwambiri ndi maupangiri osabereka. Amagwiritsidwa ntchito nthawi zambiri pama labotale pomwe kusabereka sikofunikira pakuyesa kapena kuyesa komwe kukuchitika. Kumbali inayi, malangizo a pre-chosawilitsidwa ndi pipette adapangidwa kuti ateteze kuipitsidwa. Amatsimikizika kuti alibe DNA, RNase, ATP ndi pyrogens. Chifukwa maupangiri awa a pipette ali ndi mbiri yaulere ya DNA, RNase, ATP ndi pyrogens, ndioyenera kugwiritsa ntchito komwe kumafunikira kusungika monga zikhalidwe zama cell.

Maupangiri azosefera a pipette apangidwa kuti ateteze ma aerosols kuti asapangidwe. Ma aerosol ndi tinthu tating'onoting'ono tamadzi kapena tolimba tomwe timayenda. Tinthu timeneti titha kukhalabe tomwe timayenda mlengalenga kwa nthawi yayitali ndipo titha kupumira. Choyipa chachikulu ndi chakuti, 65% yamatenda onse a labotale amayamba chifukwa cha ma aerosols, nthawi zambiri mwa kuwapumira. Malangizo a filter omwe amasefedwa amathandiza kuchepetsa chiopsezo cha ma aerosols omwe amapangidwa mu labotale. Amatetezeranso migodi ya pipette ku kuipitsidwa ndikuchepetsa chiopsezo cha kuipitsidwa pamtanda. Malangizo a pipette awa nthawi zambiri amagwiritsidwa ntchito poipitsa ntchito zowunika monga zowunikira ndi matenda azachipatala.

Ndi kuthekera kwakupeza matenda kuchokera kuma aerosol, sitingatsimikizire mokwanira kufunikira kokakamiza ntchito zotetezeka mu labotale. Izi zimaphatikizapo kupha tizilombo toyambitsa matenda mutagwiritsa ntchito ndikutaya maupangiri a pipette.
