Ukusetyenziswa kunye nokunyameka kwe-pipette

1. Ukufakwa kweengcebiso zepipette

Kwi-pipette yesiteshi esisodwa, isiphelo se-pipette sifakwe ngokuthe nkqo kwintloko yokufunxa, kwaye inokuqiniswa ngokucinezela ngobumnene ngakwesobunxele nangakwesokudla;

Kwimibhobho yamatshaneli amaninzi, lungelelanisa i-pipette yokuqala kunye nentloko yokuqala yokufunxa, yifake i-oblique, yigubungele ngasemva nangaphambili kwaye uyiqinise.

Musa ukubetha ngokuphindaphindiweyo i-pipette ukuqinisekisa ukuqina komoya kwentloko yokufunxa.Ukuba intloko yokufunxa ihlanganiswe ngolu hlobo ixesha elide, iindawo zepipette ziya kukhululeka ngenxa yempembelelo enamandla, okanye iqhosha lokulungelelanisa isikali liya kuxinga.

2. Ukusetha umthamo

Xa uhlengahlengisa ukusuka kwivolumu enkulu ukuya kwivolumu encinci, uyijikelezise ngokuchasene ne-clockwise ukuya kwisikali;Xa uhlengahlengisa ukusuka kwivolumu encinci ukuya kwivolumu enkulu, unokuhlengahlengisa ivolyum yesandi ngokwewotshi kuqala, kwaye emva koko ubuyele kwivolumu emiselweyo ukuze uqinisekise ukuchaneka okugqwesileyo.

Musa ukuguqula iqhosha lokulungelelanisa ngaphandle koluhlu, okanye isixhobo somatshini kwi-pipette siya konakala.

3. Ukufunxa kunye nokukhupha

Cinezela iqhosha le-pipette elinqwenela ulwelo kwisixhobo sokuqala kwaye ukhulule iqhosha ukuze unqwenele.Qinisekisa ukuba ungahambi ngokukhawuleza, kungenjalo ulwelo luya kungena kwintloko yokufunxa ngokukhawuleza, okuya kubangela ukuba ulwelo lufunxelwe kwakhona kwi-pipette.

Umsele wolwelo ukufutshane nodonga lwesikhongozeli.Yicinezele kwigiya yokuqala, nqumama kancinci, emva koko uyicinezele kwigiya yesibini ukukhupha ulwelo olushiyekileyo.

● Funxa ulwelo ngokuthe nkqo.

● Kwi-5ml kunye ne-10ml pipettes, intloko yokufunxa idinga ukuntywiliselwa kwinqanaba lolwelo lwe-5mm, ngokucotha ukufunxa ulwelo, emva kokufikelela kumthamo omiselweyo, nqumama phantsi komgangatho wolwelo kangange-3s, kwaye emva koko ushiye umgangatho wolwelo.

● Khulula isilawuli ngokucothayo xa unqwenela, kungenjalo ulwelo luya kungena kwintloko yokufunxa ngokukhawuleza, okuya kubangela ukuba ulwelo lufunxelwe kwakhona kwipayipi.

● Xa ufunxa ulwelo oluguquguqukayo, manzisa intloko yokufunxa amaxesha ama-4-6 ukuze uzalise umphunga kwigumbi lemikhono ukunqanda ukuvuza kolwelo.

4. Ukubekwa ngokuchanekileyo kwepipette

Emva kokusetyenziswa, inokuxhonywa ngokuthe nkqo kwindawo yokubeka umpu wolwelo, kodwa lumka ungawi.Xa kukho ulwelo kwintloko yompu wepipette, musa ukubeka ipayipi ngokuthe tye okanye ujonge phantsi ukuze ugweme ukujikeleza kolwelo olugrulisa i-piston spring.

Ukuba ayisetyenziswanga, lungisa uluhlu lokulinganisa umpu wokudlulisa ulwelo ukuya kwinqanaba eliphezulu, ukwenzela ukuba intwasahlobo ibe yindawo ekhululekile ukukhusela intwasahlobo.

5. Imisebenzi yempazamo eqhelekileyo

I-1) Xa udibanisa intloko yokufunxa, intloko yokufunxa ichaphazeleka ngokuphindaphindiweyo, okwenza kube nzima ukukhulula intloko yokufunxa, okanye yonakalise i-pipette.

2) Xa unqwenela, i-pipette iyancipha, ibangele ukuhanjiswa kwamanzi okungachanekanga, kwaye i-liquid ilula ukungena kwi-handle ye-pipette.

3) Xa ufunxa, isithupha sikhululwe ngokukhawuleza, esiza kunyanzela ulwelo ukuba wenze imeko ephazamisayo, kwaye i-liquid iya kukhawuleza ngqo ngaphakathi kwi-pipette.

I-4) Cinezela ngokuthe ngqo kwi-gear yesibini yokunqwenela (indlela esemgangathweni kufuneka ilandelwe).

5) Sebenzisa uluhlu olukhulu lwepipette ukudlulisa umthamo omncinci wesampuli (i-pipette enoluhlu olufanelekileyo kufuneka ikhethwe).

6) Beka i-pipette kunye nentloko yokufunxa ulwelo oluseleyo ngokuthe tye (i-pipette iya kuxhonywa kwi-pipette rack).
