VWR Vwr Alcon Hood Wht Cs500 Unit CS. The hood features four airflow holes and fold-away shoulders with adjustable drawstring closures a contoured brim and a snag-free adjustable hanging strap with side release buckle. The Alcon Hood also has an excellent choice for people with impaired vision. The voluntary Hi-Lo Valve can be used to convert the hood into a stand-alone visor or as a functional addition to the overall lab safety / E-Ring hood collection system. Simply add a respirator and draw the wire frame around the hood body. This effectively solves the problem of pin holes in traditional hood designs that reduce vision to pinholes. The Alcon Hood with its all white finish draws attention to the clean dry environment inside the hood.
