It is designed to ensure safe and efficient solvent waste disposal in laboratory settings. Compatible with B83-threaded containers, this funnel system enables odor-free and leak-proof disposal of solvent waste from HPLC units and other liquid waste sources. It includes a funnel with a hinged lid and sealing ring, mounted on a SafetyWasteCap equipped with an exhaust air filter to prevent vapor emissions.
