| Laboratory fume hoods are a type of ventilation system with the primary function to exhaust chemical fumes, vapors, gasses, dust, mist and aerosol. Fume hoods also serve as physical barriers between reactions and the laboratory, offering a measure of protection against inhalation exposure, chemical spills, run-away reactions and fires | ||||||
| Experimental procedures are performed within the hood which is consistently and safely ventilated, by means of an extract blower and ductwork. | ||||||
| The hood functions by maintaining a relatively negative pressure in the interior of the hood to prevent any contaminant from escaping while drawing air in through the hood opening at a consistent rate. A suitable hood face velocity (the speed at which air is drawn into the hood) is of importance to the safe and effective operation of a fume hood. While excessive face velocities can often result in turbulence and reduce containment, insufficient velocities can also compromise hood performance. | ||||||
| Fume Hoods are recommended for exhaust from the hood working area, of gases, vapour, toxic particles, odour to improve working environment of people who regularly handle toxic substances. Reduces personal exposures and odour level in the laboratory. These are designed to exhaust toxic, or otherwise harmful apours etc., for protecting laboratory personnel & equipments. A motor- blower exhaust system ( Optional) Generates Negative pressure within the hood, extracting the contaminated air from the work area and expelling it into the atmosphere and preventing the fumes from escaping into the room. These are recommended for various laboratories like Bio-Chemistry, Pharmaceutical units, printed circuit etching/cleaning etc. The work surface (Worktable) is of stainless steel sheet. A small S.S. Sink, water tap and water outlet provided. A sliding door made of acrylic, moves vertically up/down with counter balanced weight operated by steel rope. Hood is provided with fluorescent light for easy working in the chamber. A metal clad socket and gas cock is also provided in the chamber. The control panel is fitted with on/pff toggle switches for mains, motor-blower and tube light and mains indicator. computer with cardboard. Power Supply : 220V, Single Phase, 50 Cycles, AC. | ||||||
