Te whakamahi me te whakatupato i te pipette

1. Te whakaurunga o nga tohutohu paipa

Mo te pipette hongere kotahi, ka kuhu poutū te pito o te pipette ki roto i te upoko momi, a ka taea te whakakaha ma te pehi marie i te taha maui me te taha matau paku;

Mo nga pipette maha-hongere, whakahāngaitia te pipette tuatahi ki te upoko momi tuatahi, kuhu kopikopiko, ruru paku whakamuri, whakamuri, ka whakakaha.

Kaua e patu tonu i te pipette kia mau te hau o te upoko momi.Mena ka whakahiatohia te upoko momi mo te wa roa, ka wetekina nga wahanga o te pipette na te kaha o te paheketanga, ka mau ranei te puku mo te whakatikatika i te tauine.

2. Whakaritenga kaha

Ina whakatikahia mai i te rōrahi nui ki te rōrahi iti, huri i te taha karaka ki te tauine;A, no te whakatika i te rōrahi iti ki te rōrahi nui, ka taea e koe te whakatika i te rōrahi huinga karaka tuatahi, ka hoki ki te rōrahi huinga ki te whakarite i te tino tika.

Kaua e huri i te puku whakatikatika mai i te awhe, kei pakaru te taputapu miihini i roto i te pipette.

3. Momo me te tuku

Pēhia te patene pipette aspirating wai ki te taputapu tuatahi ka tuku i te paatene ki te aspirate.Kia kaha kia kaua e tere rawa, ki te kore ka tere rawa te uru o te wai ki roto i te upoko momi, ka hoki te wai ki roto i te paipa.

Kei te tata te puna wai ki te pakitara ipu.Pēhia ki te taputapu tuatahi, tatari paku, katahi ka pehia ki te taputapu tuarua kia whakahekehia te toenga wai.

● Ngongo wai poutū.

● Mo nga pipette 5ml me te 10ml, me ruku te upoko momi ki roto i te taumata wai mo te 5mm, me ata ngote i te wai, i muri i te tae ki te rōrahi kua whakaritea, okioki i raro i te taumata wai mo te 3s, ka waiho i te taumata wai.

● Kia ata wetewete te kaiwhakahaere i te wa e momi ana, ki te kore ka tere rawa te uru o te wai ki roto i te upoko momi, ka hoki te wai ki roto i te paipa.

● I te wa e ngongo ana i te wai karekau, whakamakuku i te upoko momi kia 4-6 nga wa kia kuhu te mamaoa i roto i te ruuma ringaringa kia kore ai e rere te wai.

4. Whakanoho tika i te pipette

I muri i te whakamahinga, ka taea te whakairi poutū ki runga i te whatanga pu whakawhiti wai, engari kia tupato kei taka.Ina he wai kei roto i te upoko pu o te pipette, kaua e tuu te pipette ki te taha whakapae, ki runga ranei ki raro, kia kore ai te rere whakamuri o te wai e waikino ana i te puna piston.

Ki te kore e whakamahia, whakatikahia te awhe ine o te pu whakawhiti wai ki te tauine teitei, kia noho humarie te puna hei tiaki i te puna.

5. Nga mahi hapa noa

1) I te wa e whakahiato ana i te upoko momi, he maha nga wa ka pa ki te upoko momi, he uaua ki te wetewete i te upoko momi, ka pakaru ranei te pipette.

2) I te wa e wawata ana, ka heke te pipette, ka puta he whakawhitinga wai kore, ka ngawari te uru o te wai ki te kakau o te pipette.

3) I te wa e ngote ana, ka tere te tuku mai o te koromatua, ka kaha te wai ki te hanga i te ahua ohooho, ka rere tika te wai ki roto o te pipette.

4) Patohia tika ki te taputapu tuarua mo te wawata (me whai i te tikanga paerewa o runga).

5) Whakamahia he pipette awhe nui ki te whakawhiti i te rōrahi iti o te tauira (me whiriwhiri he pipette me te awhe tika).

6) Whakatakotoria te pipette me te upoko momi wai toenga (me whakairihia te pipette ki runga i te whatanga pipette).
