Eyaziwa nangokuthi i-Pasteur pipette kanye neshubhu yokudlulisa, ivamise ukwenziwa nge-polymer material polyethylene (PE) esobala.Ihlukaniswe yaba yi-EO (i-ethylene oxide) noma i-gamma ray efakwe inzalo kanye nezinhlanga ezingasenzi inzalo.

I-pasteur pipette ine-sac engenalutho emzimbeni we-tube, engenza kube lula ukuxutshwa kwezidakamizwa ezincibilikayo kanye nemizimba yamaseli.Umzimba weshubhu uyashintshashintsha futhi umhlophe qwa, unokugeleza koketshezi olufanele odongeni lweshubhu kanye nokulawuleka okuqinile;ingasetshenziswa endaweni ewuketshezi ye-nitrogen;umzimba we-tube mncane futhi uguquguqukayo, futhi ungagoba, okulungele ukungena nokushiya iziqukathi ezincane noma ezikhethekile;Ukuphindaphinda;iziphetho zamashubhu zingavalwa ukushisa ukuze kube lula ukuthwala uketshezi.

I-Pipette wall translucent, kulula ukuyibona, i-pipette wall ene-scale, kulula ukuyikala.Izitayela kanye nokucaciswa okuhlukahlukene, i-pipette eguquguqukayo, ingakwazi ukudonsa kalula uketshezi ezitsheni eziwumngcingo, ukupakishwa kunokupakishwa okuhlukile kwepeel, ukupakishwa okuhlukile kwe-PE, ukupakishwa kwenqwaba, impahla yekhwalithi ephezulu ye-polyethylene, elungele ukumuncwa okuncane noma ukulandelela uketshezi, ilungele ukudluliswa okuphephile nokusheshayo. kanye nokusabalalisa amanani amancane oketshezi.
