Iintlobo zeePipettes zeSerological kunye nokusetyenziswa kwazo

Iipayipi ze-serological zisetyenziswa kwiilabhoratri zokuhambisa ulwelo.Ezi pipettes zinezidanga kwicala elinceda ukulinganisa ubungakanani bolwelo oluza kuchithwa okanye lufakwe kwi-milliliters okanye i-milliliters.Zinconywa kakhulu njengoko zichaneke kakhulu ekulinganiseni awona manqanaba amancinci okunyuka.

Iipayipi ze-serological zisetyenziswa ikakhulu kwezi ndawo zilandelayo:

✦ ukumiswa okuxubileyo;

✦ Ukudibanisa ii-reagents kunye nezisombululo zekhemikhali;

✦Ukutshintshela iiseli zohlalutyo lwamava okanye ukwandiswa;

✦ii-reagents ezinomaleko zokwenza i-gradients eziphezulu zokuxinana;

Kukho iintlobo ezintathu ezahlukeneyo zeepipettes zeserological:

1. Vula ipipette

Iipayipi ezivulekileyo ezineziphelo eziveziweyo zifaneleke kakhulu ukulinganisa ulwelo olubonakalayo.Ukuzaliswa ngokukhawuleza kwe-pipette kunye namazinga okukhupha ayenza ilungele ukuphatha ulwelo olufana neoyile, ipeyinti, izinto zokuthambisa, kunye nodaka.

I-pipette ikwabonisa iplagi yokucoca ifayibha enceda ukunciphisa ukungcoliseka kwamanzi.Iipayipi ezivulekileyo zi-pipette ezingenazo i-pyrogen ezifakwe i-gamma inzalo.Zihlanganiswe ngabanye kwiphepha le-thermoformed / iplastiki ukukhusela umonakalo.

Ezi pipette zifumaneka kwi-1 ml, 2 ml, 5 ml kunye ne-10 ml ubukhulu.Kufuneka bathobele umgangatho woshishino we-ASTM E1380.

2. Ipayipi yebhaktheriya

Iipayipi zebhaktheriya zenzelwe ngokukodwa ukuhlola ubisi kunye nezinye iimveliso zobisi.Ezi polystyrene milk pipettes zifumaneka kwi-1.1 ml kunye no-2.2 ml ubukhulu.

Ezi ziipayipi ezilahlwayo ezingezizo i-pyrogenic ezithi zicolwe kusetyenziswa i-gamma radiation.Ziza kwiphepha le-thermoformed / iplastiki yokupakisha ukuphepha umonakalo.Ezi pipette zibandakanya isihluzo sefayibha ukukhusela ulwelo kunye neesampuli zolwelo ekungcoleni.Iipayipi zebhaktheriya kufuneka zihlangabezane nemigangatho ye-ASTM E934 kwaye zilinganiswe ukubonelela nge (TD) ye +/-2%.

3. Umququ

I-pipette ibonakala ngokucacileyo kwaye ayinayo isidanga.Zenzelwe ngokukodwa ukuthutha kunye nokuxuba ulwelo kwizicelo ezahlukeneyo ezifana ne-vacuum okanye iinkqubo ze-pipette aspiration.Ziyalahlwa, i-pyrogen-free, i-polystyrene pipettes engavaliyo.

Ezi pipette zisongelwe kwiplastiki ye-thermoformed ukuphepha ukungcoliseka.Zivalwa kusetyenziswa imitha ye-gamma kwaye ziyahlangabezana neNqanaba lokuQinisekisa ukuNzala (SAL).
