Lab units like the 7610 barrier-free pull down eye/face wash features the medically acclaimed AXION� MSR eye/face wash head assembly (patent pending). This revolutionary inverted flow design is the only product on the market that provides a Medically Superior Response consistent with all EMT, emergency room and doctors� office protocols by sweeping contaminants away from the vulnerable nasal cavity. Traditional eyewashes irrigate from the outside edge of the eye back toward the nose, where contaminants can then be flushed into the nasal cavity through the lacrimal punctum, nature�s ocular cavity drain. Extended-length pull down arms are designed to accommodate wheel chair access. Eyewash streams provide zero vertical velocity stream engineering with even laminar flow for enhanced comfort, stability and effectiveness. Dust cover allows for the 7610 to stay protected from debris when not in use. Activation and deactivation occur at a 30 degree angle limiting splash of water onto counter or wall. Rear mount design allows the sink to remain open to other uses. Model 7610 is certified by CSA to meet the ANSI Z358.1-2009 Standard for Emergency Eyewash and Shower Equipment.
