Mhando dzeSerological Pipettes uye Mashandisiro Adzo

Serological pipettes anoshandiswa mumarabhoritari kuendesa zvinwiwa.Mapipetti aya ane magirajuduation parutivi anobatsira kuyera huwandu hwemvura inofanirwa kupihwa kana kushushwa (mumilliliters kana milliliters).Iwo anonyanya kukurudzirwa sezvo ari iwo chaiwo mukuyera iwo madiki ekuwedzera mwero.

Serological pipettes inonyanya kushandiswa munzvimbo dzinotevera:

✦ kusanganiswa kwekumiswa;

✦Kubatanidza reagents uye makemikari mhinduro;

✦Kutamisa maseru ekuongorora empirical kana kuwedzera;

✦akaturikidzana reagents ekugadzira yakakwirira density gradients;

Kune marudzi matatu akasiyana e serological pipettes:

1. Vhura pipette

Mapipeti akavhurika ane magumo akazaruka akanyatsokodzera kuyera zvakanyanya viscous zvinwiwa.Iyo pipette inokurumidza kuzadza uye kuburitsa mitengo inoita kuti ive yakakodzera kubata zvinwiwa zvakaita seoiri, pendi, zvekuzora, uye sludge.

Iyo pipette zvakare ine fiber sefa plug iyo inobatsira kuderedza kusvibiswa kwemvura.Mapipetti akavhurika-asina pyrogen-asina pyrogen akavharirwa gamma sterilized.Iwo ega akaputirwa mune thermoformed bepa / purasitiki kudzivirira kukuvara.

Aya mapaipi anowanikwa mu1 ml, 2 ml, 5 ml uye 10 ml saizi.Ivo vanofanirwa kutevedzera ASTM E1380 indasitiri chiyero.

2. Bhakitiriya pipette

Bhakitiriya pipettes yakanyatsogadzirirwa kuongorora mukaka uye zvimwe zvigadzirwa zvemukaka.Iyi polystyrene mukaka pipettes inowanikwa mu 1.1 ml uye 2.2 ml saizi.

Aya mapipette asiri epyrogenic anoraswa anovharirwa achishandisa gamma mwaranzi.Ivo vanouya mune thermoformed bepa / epurasitiki kurongedza kudzivirira kukuvara.Aya mapipette anosanganisira faibha sefa yekudzivirira zvinwiwa nemasampuli emvura kubva pakusvibiswa.Bhakitiriya pipettes inofanirwa kusangana neASTM E934 miyero uye yakagadziriswa kuti ipe (TD) ye +/-2%.

3. Mashanga

Iyo pipette inonyatsojeka uye haina kupedza kudzidza.Iwo akagadzirirwa chaizvo kutakura uye kusanganisa zvinwiwa mumashandisirwo akasiyana senge vacuum kana pipette aspiration maitiro.Izvo zvinoraswa, pyrogen-isina, isina-kuvhara polystyrene pipettes.

Aya mapipetti akaputirwa mupurasitiki yakashongedzwa kuti arege kusvibiswa.Ivo vanoitwa sterilized vachishandisa gamma rays uye vanosangana neiyo Sterility Assurance Level (SAL).
