A method for production of low molecular weight heparin (LMW-heparin) by enzymatic batch depolymerization of heparin with heparinase wherein heparin is depolymerized to a desired weight average molecular weight by depolymerization to the corresponding number average molecular weight. The method enables depolymerization to a desired weight average molecular weight by measuring the increase in UV-absorption (preferably at 230-235 nm) .DELTA.A235 and halting the depolymerization when .DELTA.'A235 has reached the calculated value corresponding to the desired number average molecular weight Mn.
