Change of storage solution for C4 HLD columns

7Oct2020

Dear customer,

We inform you that the storage solution for C4 HLD columns was changed from 10 mM NaOH to 20 % ethanol as of 7 October 2020. All columns with later manufacturing date are now shipped and stored in the new solution. This change was implemented in order to harmonize the storage solution of our products and it does not alter the column performance.
