Safetec Green-Z® Drop-In Pacs help improve operating room turnover, efficiency and safety when handling or transporting liquid medical waste with use of pre-measured solidifier Drop-In Pacs - Red Z and Green-Z. The pacs are made of a non-woven teabag material and once fluid is added, solidifier will activate and burst through packaging to solidify the contents.
