A well-designed chemical fume hood, when properly installed and maintained, offers a substantial degree of protection to the user, provided that it is used correctly and its limitations are understood ...

VAV laboratory fume hoods have dominated the laboratory design world for the last 25 years. Conventional wisdom suggests that the specification of the design exhaust flow rate for them is an ...

Semiconductor fabrication is complicated requiring nasty chemicals for everything from dopants to etchants. Working with such chemicals at home is dangerous and after releasing hydrochloride acid ...

Walls lined with humming fume hoods are a defining feature of many chemistry laboratories. These safety devices, part of a lab’s overall ventilation system, suck hazardous airborne chemicals away from ...

If your chemical fume hood has low or no airflow, broken dome lights, broken sash (or sash is difficult to slide up or down), airflow sensor malfunction, or the hood needs annual re-certification, etc ...

Traditional laboratory chemical (or fume) hoods are designed to capture and control chemical vapors and pull them away from the worker. Although the inward flow of air provides protection to the user, ...

In a paper recently published in the journal Japan Architectural Review, researchers used computational fluid dynamics (CFD) to evaluate a fume hood’s capture performance and the factors influencing ...

The UniFlow SE Dual Entry Hood has launched with safety glass sashes front and rear to allow observers a clear view as well as access to procedures. A split transparent baffle system provides airflow ...
