Description
Depending on the chain length, chitosans and chitosan derivatives have different dynamic viscosities in solution. The viscosity of chitosans and chitosan derivatives is determined in a 1 % solution in 1 % acetic acid or RO water using a Brookfield viscometer (rotational viscometer) (Ph. Eur., 2.2.10).
Required sample quantity: 7 g (chitosan), 2 g (chitosan derivative)
Duration: 2-4 weeks
