Ipayipi eliqondile lokudlulisa ivolumu

Umsebenzi wepayipi le-Kedun elinembile lokudluliswa kwevolumu ukukhipha isampula eliwuketshezi elinembe ngokunemba okungu-10%. Yenziwe nge-LDPE (i-polyethylene e-low density ), iphayiphi yokudlulisa ivolumu ayiyona-nobuthi futhi imelana namakhemikhali. Ihlinzeka ngevolumu enembile kumapayipi, ukudlulisa kanye nokukhipha isampula yoketshezi noma i-reagent ezindaweni eziningi zokusebenza okubandakanya ilabhorethri, isibhedlela kanye nendawo yomphakathi.

Kukhona isibani esingaphezulu kwepayipi yokukhama kanye nokuhogela umoya ukuze ulawule ukucindezela kwangaphakathi, enye isibani sisetshenziselwa ukumunca uketshezi oluthe xaxa noma umoya ukuze ipayipi igcwale ngoketshezi. Ngakho-ke, isampula ye-liquid noma i-reagent ifakwe ngamapayipi futhi ikhishwe ngesandla esisodwa kalula. Indawo ephansi-ehambisanayo ivimbela ukubophezela kwamaprotheni kuhlelo lokusebenza locwaningo.
