The Osmomat 090 enables the measurement of the average molecular weight (Mn) of polymers that are soluble in aqueous or organic solvents within the range of 10,000 to 2,000,000g/Mol. The measurement is highly dependent on the membrane that is used. Gonotec offers membranes with different "cutoffs" that are made of different materials, so that a suitable configuration can be offered for most applications. This cell unit must be operated by a Gonotec Control Unit SA or Control Unit B.
