    en.wikipedia.org/wiki/Dialysis_tubing

    Different dialysis tubing or flat membranes are produced and characterized as differing molecular-weight cutoffs (MWCO) ranging from 1–1,000,000 kDa. The MWCO determination is the result of the number and average size of the pores created during the production of the dialysis membrane.

    en.wikipedia.org/wiki/Molecular_weight_cut-off

    In ultrafiltration, the molecular weight cut-off or MWCO of a membrane refers to the lowest molecular weight of the solute (in daltons) for which 90% of the solute is retained by (prevented from passing through) the membrane, [1] or the molecular weight of the molecule (e.g. globular protein) that is 90% retained by the membrane.

    en.wikipedia.org/wiki/Dialysis_(chemistry)

    The MWCO of a membrane is the result of the number and average size of the pores created during production of the dialysis membrane. The MWCO typically refers to the smallest average molecular mass of a standard molecule that will not effectively diffuse across the membrane during extended dialysis.

    Nanotechnology is being used in some of the most recent high-flux membranes to create a uniform pore size. The goal of high-flux membranes is to pass relatively large molecules such as beta-2-microglobulin (MW 11,600 daltons), but not to pass albumin (MW ~66,400 daltons). Every membrane has pores in a range of sizes. As pore size increases ...

    Molecules that are significantly smaller than the MWCO penetrate into the pores of the resin, while molecules larger than the MWCO are unable to enter the pores and remain together in the void volume of the column. By passing samples through a column resin bed with sufficient length and volume, macromolecules can be fully separated from small ...

    The pore distribution of a fictitious ultrafiltration membrane with the nominal pore size and the D 90. The pore sizes of technical membranes are specified differently depending on the manufacturer. One common distinction is by nominal pore size. It describes the maximum pore size distribution [9] and gives only vague information about the ...
