Ungakhetha kanjani ithiphu elifanele le-pipette?

Ukuthengwa kwe-pipette kufanele kucabangele izici ezilandelayo zenkinga

1. Ukusebenza kwekhwalithi ephezulu
2. Uhlelo oluhlukile lokulawula ivolumu
3. Ukunemba okungaguquki nokuphindaphinda
4. Ithembekile futhi ihlala isikhathi eside
5. Umklamo we-ergonomic

Uma i-pipette ingaba nomthamo oguquguqukayo noma umthamo ongaguquki, kusho ukuthi kukhona i-piston yebanga eliguquguqukayo kanye nepiston yebanga elingashintshi ku-pipette.Lokhu kusho ukuthi i-pipette yomkhiqizo inikeza abasebenzisi imisebenzi emibili ezingeni lentengo le-pipette eyodwa.Ezinye izinhlobo zomsebenzi we-pipette azikhawulelwe kulokhu, hhayi kuphela i-pipette ngayinye ene-piston ene-fixed umthamo, futhi ungathenga nolunye uhla lwamapistoni angaguquki afakwe ku-pipette, intengo iphansi kakhulu kunentengo yokuthenga i-pipette yebanga elingaguquki. .

Ikhono le-pipette ukuhlanganisa ne-Tip head lifanelekile

Inhlanganisela ye-pipette kanye nenhloko ye-Tip iyisiqinisekiso sokunemba nokukhiqiza kabusha, ukukhuluma ngokuvamile, inhlanganisela ye-pipette ne-Tip isesimweni somlomo oqondile, le ndlela iqine kakhulu, kodwa esikhundleni sekhanda le-Tip idinga ukuba ngaphezulu. kanzima, ngokuhamba kwesikhathi ukuhlanganiswa kwe-pipette ne-Tip head kuzoba nomthelela omubi, kunethuba elikhulu lokuthinta ukunemba kwesampula.Amanye ama-brand of pipette afakwe ama-O-rings aphindwe kabili, angaqinisekisa ukuthi iphutha lesampula lingaphansi kuka-1% wephutha elimisiwe.I-O-ring yenza ibhondi inembe kakhudlwana, ngaleyo ndlela inciphise amaphutha angacacile.Le pipette wonke umuntu ekuthengeni, angase afise ukwenza ireferensi, ngoba le pipette ingaba efanelekile kumakhanda amaningi we-Tip.
