Ninde utazi acetone, Ethanol & co. Gutangira Kunyerera Kuva iumuyoboronyuma yo kwifuza? Birashoboka, buri wese muri twe yarabyiboneye. Tuvuge ko ibisubizo byibanga nka "gukora byihuse bishoboka" mugihe "gushyira imiyoboro hafi cyane kugirango wirinde gutakaza imiti no kumeneka" nibikorwa byawe bya buri munsi? Nubwo ibitonyanga byimiti byiruka byihuse birashoboka kwihanganira ko imiyoboro itagikora neza. Gusa impinduka ntoya mubuhanga bwo kuvoma, hamwe no guhitamo neza ubwoko bwa pipette burashobora gufasha gutsinda ibyo bibazo bya buri munsi!
Kuki imiyoboro itonyanga?
Imiyoboro ya kera itangira gutonyanga mugihe cyohereza amazi ahindagurika bitewe numwuka uri muri pipeti. Ibi bita air cushion ibaho hagati yicyitegererezo cyamazi na piston imbere muri pipette. Nkuko bisanzwe bizwi, umwuka uroroshye kandi uhuza ningaruka zo hanze nkubushyuhe numuvuduko wumwuka muguka cyangwa kwikuramo. Amazi nayo ashobora guterwa ninyuma kandi mubisanzwe bigenda byuka kuko ubuhehere bwumwuka buri hasi. Amazi ahindagurika yuka vuba cyane kuruta amazi. Mugihe cyo kuvoma, kijya mu kirere cyo mu kirere gihatira icya nyuma kwaguka kandi amazi agakurwa mu muyoboro wa pipeti… igitonyanga gitonyanga.
Nigute wabuza amazi gutemba
Uburyo bumwe bwo kugabanya cyangwa guhagarika ibitonyanga ni ukugera ku ijanisha ryinshi ryubushuhe mu kirere. Ibi bikorwa mbere yo guhanaguraumuyoborohamwe no kuzuza umusego wo mu kirere. Iyo ukoresheje amazi make ahindagurika nka 70% Ethanol cyangwa 1% acetone, aspirate hanyuma utange icyitegererezo cyamazi byibuze inshuro 3, mbere yo kwifuza urugero rwicyitegererezo ushaka kwimura. Niba ubunini bwamazi ahindagurika ari menshi, ongera usubiremo inshuro 5-8. Ariko, hamwe nibitekerezo byinshi cyane nka 100% Ethanol cyangwa chloroform, ibi ntibihagije. Nibyiza gukoresha ubundi bwoko bwa pipette: umuyoboro mwiza wo kwimura. Iyi pipeti ikoresha inama hamwe na piston ihuriweho idafite umusego wo guhumeka. Icyitegererezo kiri muburyo butaziguye na piston kandi nta ngaruka zo gutonyanga.
Ba umutware wo kuvoma
Urashobora kunonosora byoroshye ubunyangamugayo bwawe mugihe ushizemo amazi ahindagurika uhitamo tekinike nziza cyangwa uhindura igikoresho ukoresha. Byongeye kandi, uzongera umutekano wirinda kumeneka no koroshya akazi kawe.
