Robert M. Rioux & William A. Elliott, Pennsylvania State University, University Park, PA Fume hoods and laminar flow cabinets are engineering controls that operate under similar principles. Both use a constant flow of air to prevent contamination of the laboratory environment and its inhabitants. Fume hoods prevent hazardous substances from exiting the hood workspace, whereas laminar flow cabinets prevent contaminants from entering the cabinet workspace. Fume hoods are ventilation systems...

An Introduction to Working in the Hood
0 Views •
2023
Hoods are a common class of instrument, which act as a protective enclosure for various types of laboratory experiments. They serve to shield experimental samples from the environment, as well as to protect the researcher from hazardous or infectious samples. “The Hood” is a term that can include laminar flow benches, fume hoods, as well as tissue culture hoods or biosafety cabinets. All hoods operate based on the principle of laminar flow and have the same basic components, including a...

A fast and inexpensive method for the behavioral determination of hearing parameters like hearing thresholds, hearing impairments or phantom perceptions (subjective tinnitus) is described. It uses pre-pulse inhibition of the acoustic startle response and can be easily implemented in a personal computer using a programmable AD/DA-converter and a piezo sensor.

Here, we present a protocol to adapt the Taylor dispersion experiment to the microscale using microchannels fabricated in-house with a desktop craft cutter. The experimental platform can be used to compute the diffusion coefficient of single-species passive tracers and to visualize multispecies ion interaction and separation.

FAQs
Airflow direction determines whether contaminated air can move toward the hood exhaust rather than around obstructing objects or back into the room. Materials should remain away from airflow openings so they do not interfere with inward air movement. This placement supports more consistent containment and helps the ventilation system remove vapors, gases, aerosols, and dust effectively.
The sash provides a physical barrier between the researcher and materials inside the hood, while internal baffles help regulate the movement of air through the enclosure. Together, they support containment without relying only on distance from the chemicals. Keeping these components unobstructed allows the hood to maintain its intended airflow pattern during chemistry work.
Clutter can interfere with the movement of air across the work surface and may block airflow openings. A minimally arranged workspace gives vapors, gases, aerosols, and dust a clearer path toward the exhaust system. This improves the hood's ability to maintain a controlled environment and reduces the chance that stored or misplaced items disrupt containment.
Before starting chemistry work, arrange the necessary materials so they remain clear of airflow openings, remove unnecessary clutter, and confirm that the hood operates correctly. The sash and internal components should remain available to perform their intended roles. Completing these checks before handling chemicals helps establish the controlled work environment needed for safer laboratory operations.
Readiness is established by checking that the hood operates correctly before work begins. The setup should also show an organized work surface, unobstructed airflow openings, and appropriate use of the sash and internal baffles. These observations help confirm that the ventilation and containment features are available to support chemical handling rather than discovering a problem after work has started.
Careful setup is relevant whenever chemistry work may release hazardous vapors, gases, aerosols, or dust. Proper organization and operation help the hood contain these airborne materials and discharge them through the ventilation system. The approach therefore supports safer handling across laboratory tasks involving airborne chemical hazards, while maintaining a more controlled environment for researchers.
