Ethidium Bromide Disposal

Risk Management recommends the following methods for disposing of spent electrophoresis gels and Ethidium Bromide (EtBr) contaminated materials:

  • Less than 0.1% EtBr should be disposed of as regular trash. Gels should be double bagged in black or buff bags. Both bags need to be sealed and weigh no more than 15 pounds.
  • More than or equal to 0.1% EtBr or dark pink or red gels, dispose as biohazardous waste. Double bag waste in red or orange bags. Seal both bags and deposit in biohazardous waste barrel for ultimate disposal.
  • Heavily contaminated gloves, tubes and wipes should be disposed of as biohazardous waste.

Ethidium Bromide can be removed from solutions using a filter available from Risk Management. Ethidium Bromide solutions should not be poured down the drain.
