Ethidium Bromide de-staining bags are used for the removal of Ethidium Bromide from solutions containing this dye. Each bag will remove up to 5mg of Ethidium Bromide overnight. The rate of de-staining is improved if more de-staining bags are added to the solution. Changing bags during de-staining increases the rate at which adsorbtion occurs. The majority >72% of Ethidium Bromide is removed within 120mins leading to 100% overnight.
Once the Ethidium has been removed the buffer can be poured into the municiple drainage system, as it is now considered non-hazardous.
