Safetec Red Z Solidifiers For Spill Control - Treats 3 Liters (2oz Pouch) - Red ZRed Z Solidifiers provide state-of-the-art response for spill control and clean-up of potentially biohazardous fluids. The encapsulation technology captures and immobilizes fluid activity up to 100 times it weight. The high AUL (absorbency under load) prevents fluids from leaking out, preventing aerosolization, reducing the risk of cross-contamination.
