Mitundu ya Serological Pipettes ndi Ntchito Zawo

Serological pipettes amagwiritsidwa ntchito m'ma laboratories kusamutsa zakumwa.Ma pipettes ali ndi omaliza maphunziro kumbali yomwe imathandiza kuyeza kuchuluka kwa madzi omwe amayenera kuperekedwa kapena kukhutitsidwa (mu milliliters kapena milliliters).Amalimbikitsidwa kwambiri chifukwa ali olondola kwambiri poyeza magawo ang'onoang'ono owonjezera.

Serological pipettes amagwiritsidwa ntchito makamaka m'madera otsatirawa:

✦ kuyimitsidwa kosakanikirana;

✦ Kuphatikiza ma reagents ndi mankhwala;

✦Kusamutsa ma cell kuti afufuze mozama kapena kukulitsa;

✦ma reagents osanjikiza kuti apange ma gradients apamwamba kwambiri;

Pali mitundu itatu yosiyanasiyana ya serological pipettes:

1. Tsegulani pipette

Ma pipette otseguka okhala ndi malekezero owonekera ndi oyenera kuyeza zamadzimadzi zowoneka bwino kwambiri.Kudzaza ndi kutulutsa kwa pipette kumapangitsa kukhala koyenera kunyamula madzi monga mafuta, utoto, zodzoladzola, ndi matope.

Pipette imakhalanso ndi pulagi ya fiber filter yomwe imathandizira kuchepetsa kuipitsidwa kwamadzimadzi.Ma pipette otseguka ndi ma pipette opanda pyrogen omwe atsekedwa ndi gamma.Amayikidwa payekhapayekha mu pepala la thermoformed / pulasitiki kuti ateteze kuwonongeka.

Ma pipettes amapezeka mu 1 ml, 2 ml, 5 ml ndi 10 ml.Ayenera kutsatira muyezo wamakampani a ASTM E1380.

2. Bakiteriya pipette

Ma pipette a bakiteriya amapangidwa makamaka kuti aziwunika mkaka ndi mkaka wina.Ma pipette amkaka awa a polystyrene amapezeka mu makulidwe a 1.1 ml ndi 2.2 ml.

Awa ndi mapaipi otayira omwe si a pyrogenic omwe amawuzidwa pogwiritsa ntchito ma radiation a gamma.Amabwera m'mapepala a thermoformed / pulasitiki kuti apewe kuwonongeka.Ma pipettes amaphatikizapo zosefera zoteteza madzi ndi zitsanzo zamadzimadzi kuti zisaipitsidwe.Mapaipi a bakiteriya ayenera kukwaniritsa miyezo ya ASTM E934 ndikuwunikidwa kuti apereke (TD) ya +/-2%.

3. Udzu

Pipette imawonekeratu ndipo ilibe maphunziro.Amapangidwa makamaka kuti azinyamula ndi kusakaniza zamadzimadzi muzinthu zosiyanasiyana monga vacuum kapena pipette aspiration process.Ndiwotayidwa, opanda pyrogen, osatsekeka a polystyrene pipettes.

Ma pipette awa amakulungidwa mu pulasitiki ya thermoformed kuti apewe kuipitsidwa.Amatsekeredwa pogwiritsa ntchito kuwala kwa gamma ndipo amakumana ndi Sterility Assurance Level (SAL).
