The Esco Cytoculture® Lead-Shielded Class II biosafety cabinet is designed for radiopharmaceutical industry usage and protects the operator during work involving radioisotopes.
Superior Protection for Radioisotope Laboratories
The operator is protected from radiation by the lead-shielded sides, lead-shielded work zone bottom and front sliding sash. The air enters the cabinet through the front air grille, and travels through the KI-impregnated carbon filter on which radioactive iodine is adsorbed. Air then travels to the blower plenum where it is filtered by high-efficiency ULPA filters before being exhausted.
