How do I know which fume hood is right for my lab?

Types of fume hoods include bench-top, floor-mounted, double-faced, and portable. The right type of fume hood you need will depend on what materials will be present in your lab, the amount of chemicals you work with, how often you will use the hood, and the kind of ductwork in your workspace. To determine the right fume hood for you, consider your laboratory layout, your budget, the scope of your project, and the chemicals you will be using.
