A practical and cost effective alternative to metal fume hoods, Scienceware® translucent polypropylene hoods are non-conductive, chemical resistant, and corrosion proof while allowing light to shine through into the work area. For added convenience and accessibility, the door is made of clear acrylic for unimpeded visibility and may be set open at three positions from 25cm (10") to 53cm (21"). Durable construction includes 6.4mm (1/4") thick polypropylene with heavier sections where needed. Outside dimensions are 122cm (48") wide, 61cm (24") deep, and 91cm (36") high. A full length 3.2mm (1/8") thick interior baffle directs airflow across the table surface as well as vertically. The connecting stack has a 152mm (6") outside diameter, with a damper. An exhaust system capable of drawing 500 cfm (free air) is recommended. Shipping weight 45.4 kg. (100 lbs).
