Indlela yokukhetha i-pipetti efanelekileyo?

Ukuthengwa kwe-pipette kufuneka kuthathelwe ingqalelo le miba ilandelayo yengxaki

1. Ukusebenza komgangatho ophezulu
2. Inkqubo yolawulo lwevolumu eyahlukileyo
3. Ukuchaneka okuhambelanayo kunye nokuphindaphinda
4. Uthembekile kwaye uhlala ixesha elide
5. Uyilo lwe-ergonomic

Ukuba i-pipette ingaba nomthamo oguquguqukayo okanye umthamo osisigxina, kuthetha ukuba kukho i-piston yoluhlu oluguquguqukayo kunye nepiston yoluhlu olusisigxina kwipayipi.Oku kuthetha ukuba i-pipette ye-brand inikezela abasebenzisi imisebenzi emibini kwinqanaba lexabiso le-pipette enye.Ezinye iimpawu zomsebenzi we-pipette azikhawulelwanga kule nto, kungekhona kuphela i-pipette nganye enepiston yomthamo osisigxina, kwaye unokuthenga olunye uluhlu lweepistoni ezisisigxina ezifakwe kwi-pipette, ixabiso liphantsi kakhulu kunexabiso lokuthenga uluhlu olusisigxina .

Ikhono le-pipette ukudibanisa nentloko yeNgcaciso ifanelekile

Ukudityaniswa kwe-pipette kunye nentloko yeNcam isiqinisekiso sokuchaneka kunye nokuphindaphinda, ukuthetha ngokubanzi, ukudibanisa i-pipette kunye neNcam ikwimo yomlomo othe ngqo, le ndlela yomelele ngakumbi, kodwa ekutshintsheni intloko yeNcam kufuneka ibe ngaphezulu. nzima, ngokuhamba kwexesha indibaniselwano pipette kunye Tip intloko iya kuba nefuthe elibi, kukho ithuba elikhulu lokuchaphazela ukuchaneka isampuli.Ezinye iimpawu ze-pipette zixhotyiswe nge-double-layer O-rings, enokuqinisekisa ukuba impazamo yesampuli ingaphantsi kwe-1% yephutha elibekiweyo.I-O-ring yenza ibhondi ichaneke ngakumbi, ngaloo ndlela inciphisa iimpazamo ezingachanekanga.Le pipette wonke umntu ekuthengeni, unokunqwenela ukwenza ireferensi, kuba le pipette inokufaneleka kwiintloko ezininzi zeTip.
