Weighing hazardous or potent substances within conventional fume cupboards is problematic. The design of standard cabinets creates a roll in the airflow, which disrupts the operation of sensitive analytical balances. Now available through Anachem is a new design of fume hood that eliminates turbulence, allowing top loading, analytical, semi-micro and micro balances to be used accurately and in safety.
The Flow Sciences Vented Balance Safety Enclosure (VBSE) achieves a constant, laminar airflow by drawing air into a rear plenum through specially designed slots. The opening to the chamber has airfoils of angled acrylic in the sides and top window that allow the air to enter without creating eddy currents. An additional turning vane foil in the base redirects air into the enclosure eliminating escape.
The VBSE is constructed from clear 10mm acrylic with a chemically resistant phenolic resin base, made to contain spillages. The system does not require external ducting, making it mobile for siting on a bench or table top, allowing access in a seated or standing position. Compared with traditional fume cupboards, it uses 80 per cent less air, making savings in heating, air-conditioning and clean room conditioning costs.
The Bagout HEPA Filter has asafe change facility which avoids any contact with thehazardous waste. u
