1. Sebenzisa amathiphu afanelekile wepayipi:
Ukuze kuqinisekiswe ukunemba okungcono nokunemba, kunconywa ukuthi ivolumu yepayipi ibe phakathi kwebanga lika-35% -100% lethiphu.
2. Ukufakwa kwekhanda lokumunca:
Ezinhlotsheni eziningi zamapayipi, ikakhulukazi ama-pipettes aneziteshi eziningi, akulula ukuyifakaIthiphu ye-Pipette: ukuze uphishekele uphawu oluhle, udinga ukufaka isibambo se-pipette esiphundu bese usiphendulela kwesokunxele nakwesokudla noma usinyakazise phambili nangemuva. Qinisa. Kukhona futhi abantu abasebenzisa i-pipette ukushaya ngokuphindaphindiwe ithiphu ukuze bayiqinise, kodwa lokhu kusebenza kuzobangela ukuthi ithiphu iguqule futhi ithinte ukunemba. Ezimweni ezimbi kakhulu, i-pipette izolimala, ngakho-ke imisebenzi enjalo kufanele igwenywe.
3. I-engeli yokucwiliswa nokujula kwethiphu ye-piette:
I-angle yokucwilisa ithiphu kufanele ilawulwe ngaphakathi kwama-degree angu-20, futhi kungcono ukuyigcina iqondile; ukujula kokucwiliswa kwethiphu kunconywa ngale ndlela elandelayo:
Ukujula kokucwiliswa kwethiphu ye-Pipette
2L kanye 10 L 1 mm
20L kanye 100 L 2-3 mm
200L kanye 1000 L 3-6 mm
5000 L kanye 10 mL 6-10 mm
4. Hlanza ithiphu le-pipette:
Kumasampuli kuzinga lokushisa legumbi, ukuhlanza ithiphu kungasiza ukuthuthukisa ukunemba; kodwa kumasampuli anezinga lokushisa eliphezulu noma eliphansi, ukuhlanza ithiphu kuzonciphisa ukunemba komsebenzi. Sicela unake ngokukhethekile abasebenzisi.
5. Isivinini sokumunca uketshezi:
Ukusebenza kwamapayipi kufanele kugcine isivinini sokumunca esibushelelezi futhi esifanele; isivinini sokulangazelela esishesha kakhulu sizobangela kalula ukuthi isampula lingene kumkhono, lidale umonakalo ku-piston nendandatho yesivalo kanye nokungcoliswa okuphambene kwesampula.
[Phakamisa:]
1. Gcina ukuma okulungile lapho ufaka amapayipi; ungabambeli i-pipette ngokuqinile ngaso sonke isikhathi, sebenzisa i-pipette nge-hook yomunwe ukusiza ukukhulula ukukhathala kwesandla; shintsha izandla njalo uma kungenzeka.
2. Hlola njalo isimo sokuvala i-pipette. Uma kutholakala ukuthi uphawu luyaguga noma luyavuza, iringi yokuvala kufanele ishintshwe ngesikhathi.
3. Linganisa i-pipette izikhathi ezingu-1-2 ngonyaka (kuye ngokuthi imvamisa yokusetshenziswa).
4. Ngama-pipettes amaningi, ungqimba lwamafutha okugcoba kufanele lusetshenziswe ku-piston ngaphambi nangemva kokusetshenziswa isikhathi esithile ukuze kugcinwe ukuqina.
