Spectra/Por3透析膜

     MWCO：3500D

       性質：用于常規透析含有甘油的標準RC膜

Because Standard Regenerated Cellulose （RC） is composed of natural cellulose regenerated from cotton linters, these membranes are perfectly suited for a broad range of laboratory dialysis. This clear and flexible membrane type with a symmetric porosity is economical and sturdy, ideal for desalting, buffer exchanges, macromolecular purifications and other general applications. Possessing a broad range of chemical compatibilities, Standard RC membranes can be used with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organic solvents, including DMSO. Exposure to some strong organic solvents may damage RC membranes. Standard RC can be used with pH 2-12 & temperatures 4-121 °C. While the low level heavy metal impurities in Standard RC typically pose no problem, they can easily be eliminated using Spectrum's Heavy Metal Cleaning Solution. Standard RC Membrane is available in rolls of dialysis tubing （dry or pre-treated）, dialysis trial kits, ready-to-use dialysis sacks & flat sheet （discs or square sheets）.
