D-Formalizer is a safe chemical treatment for neutralizing spent formalin. It leaves a clear solution, free of solids and aldehyde odor, that can be disposed of without clogging the drains.
Simply add one packet of D-Formalizer to a gallon of used formalin and agitate gently. After 15 minutes, the product can be safely poured down the drain in compliance with local ordinances. The resulting solution will have a pH between 6 and 9 and will be free of polymer by-product. An aldehyde kit is also available to test for residual aldehyde and includes 100 tests per box.
D-Formalizer is availabe per package or in a case of 10 packages.
