Aldex® is perfect for glutaraldehyde disposal. Container is pre-filled with crystals, just pour spent cold sterile solution into the container. Aldex® neutralizes and crosslink's 10% formalin or up to 4% glutaraldehyde and converts it into a non-toxic, non-hazardous end-product that can be safely disposed in your regular trash with our crystalline powder product. Aldex® also reduces exposure to potentially hazardous vapor emanating from most aldehydes.
