Katiriji ya B&M G25 ndi mtundu wakale wa dextran ndi epoxy chlororopane crosslinking sing'anga. Sieve ya molekyulu imagwiritsidwa ntchito kuchotsa mamolekyu ang'onoang'ono ndikuchotsa mchere ndikuyikanso buffer. Kukula kwa molekyulu ya gel-filtration wosanjikiza imagwiritsidwa ntchito kuwongolera kamolekyu yaying'ono kudzera pakatikati, kuti akwaniritse cholinga cholekanitsa ndi kuyeretsa.

Ndi chinthu chomwe chimatha kuchotsa kulemera kwa maselo osakwana 5KD kuchokera ku nucleic acid ndi mapuloteni, monga ethanol, mchere, fulorosenti, shuga, etc.

Gawo la G25 desalination likugwiritsidwa ntchito kwambiri kuchotsa mchere ndi mamolekyu ang'onoang'ono kuchokera ku labotale kupita ku mafakitale.

Zogulitsa

Makatiriji a katiriji otsuka mchere a G25 amatenga zinthu za polypropylene, zololera ku acid-base komanso zosungunulira zambiri za organic;

Sieve mbale utenga kopitilira muyeso-mkulu molekyulu polyethylene chuma popanda kubweretsa zonyansa zina.

Kusankha kwambiri;

Kuthamanga kwa njere kumakhala kofulumira, kufulumira kwa njere kumakhala kocheperako ndipo kumera kumakwera.

Nthawi yoyeretsa ndi yayifupi, kugwiritsa ntchito kwamadzimadzi kumakhala kochepa.
