Traditional pipette njira

Njira yachikhalidwe yoyeretsera pipette:

Muzimutsuka ndi madzi apampopi ndiyeno zilowerere ndi chromic acid kutsuka njira.Njira zenizeni zogwirira ntchito ndi izi:

(1) Gwiritsani ntchito dzanja lanu lamanja kuti mugwire kumtunda kwa pipette pamalo oyenera, chala cholozera chili pafupi ndi pakamwa chapamwamba cha pipette, chala chapakati ndi chala cha mphete chotsegula ndikugwira kunja kwa pipette, chala chachikulu. imagwiridwa pa malo apakati pakati pa chala chapakati ndi chala cha mphete mkati mwa pipette, ndipo chala chaching'ono chimamasuka mwachibadwa;

(2) Tengani mpira wotsuka khutu ndi dzanja lamanzere, ndi pakamwa lakuthwa kumunsi, tulutsani mpweya mu mpirawo, ikani nsonga ya mpira wokokera khutu mkati kapena pafupi ndi pakamwa kumtunda kwa pipette, ndipo samalani kutayikira mpweya.Pang'onopang'ono masulani chala cha dzanja lanu lakumanzere, pang'onopang'ono yamwani chotsukira mu chubu mpaka chikafika pamwamba pa sikelo, chotsani mpira wa khutu, mwamsanga mutseke kumtunda kwa chubu ndi chala chanu chakumanja, ndiyeno bwezerani chotsukiracho. botolo lapachiyambi patapita kanthawi;

(3) Tsukani makoma amkati ndi akunja a pipette ndi madzi apampopi popanda madontho a madzi, ndiyeno muzitsuka ndi madzi osungunuka katatu, ndikuwongolera madzi owuma kuti muyime;

Njira yoyeretsera molingana ndi digiri ya kuipitsa:

(1) Kuyeretsa kwachindunji ndi madzi osungunuka: kuika pipette ya galasi m'madzi osungunuka kuti ayeretse kapena kutsuka, fumbi lokha likhoza kutsukidwa.

(2) Kuyeretsa zotsukira: njira ya alkaline imakhala ndi mphamvu zowononga pagalasi, ndipo imatha kutsukidwa ndi zotsukira zopanda ndale.Tsukani kapena kutsuka galasi la pipette ndi madzi okhala ndi zotsukira, ndiyeno muzimutsuka ndi madzi osungunuka, omwe amagwiritsidwa ntchito poyeretsa madontho amafuta.

(3) Mafuta odzola a Chromic acid: gwiritsani ntchito mafuta odzola a chromic acid kapena mafuta odzola apadera kuti mulowetse ndikutsuka ndi madzi osungunuka kuti muchotse madontho amakani.
