How to Choose the Best Lab Fume Hoods
Key Factors to Consider When Buying a Lab Fume Hood
When selecting a lab fume hood, several factors are crucial to ensure safety and efficiency. Prioritize these elements to make the best choice for your laboratory.
Type of Fume Hood: Different types of fume hoods are designed for various applications. Standard bypass hoods are common for general use, while auxiliary air hoods can be beneficial in areas with limited makeup air. Explainers like ductless or filtered hoods are suitable for specific contaminants and may not require external ventilation. Consider the chemical resistance and physical durability needed for your workspace.
Size and Airflow: The physical dimensions of the fume hood must fit your available space and accommodate your equipment. More importantly, ensure adequate face velocity (the speed of air moving into the hood opening) to effectively capture and contain contaminants. Check the National Safety Foundation (NSF) or ASHRAE standards for recommended face velocities based on the types of chemicals you'll be working with.
Material and Construction: The materials used in the fume hood's construction directly impact its durability and chemical resistance. Stainless steel, epoxy-coated steel, and certain plastics are common choices. Ensure the work surface is resistant to spills and easy to clean. Consider the quality of the sash material (typically tempered glass) and its smooth operation.
Frequently Asked Questions
What is the primary function of a lab fume hood?
The primary function of a lab fume hood is to provide a ventilated workspace that captures and exhausts hazardous fumes, vapors, gases, and airborne particles away from the user and the laboratory environment. This helps to prevent inhalation exposure to dangerous substances.
How do I determine the correct size fume hood for my lab?
Consider the available counter space and the size of the equipment you intend to place inside the hood. Measure your space accurately and compare it with the external dimensions of the fume hood. Also, think about the workflow and how much working room you will need within the hood.
What is face velocity and why is it important?
Face velocity refers to the speed at which air enters the fume hood opening. It's critical for effective containment, ensuring that hazardous vapors are drawn into the hood and exhausted properly. Insufficient face velocity can lead to contaminants escaping into the lab.
Are ductless fume hoods a suitable alternative to ducted hoods?
Ductless fume hoods use filters to remove contaminants, making them a good option for labs without external ventilation or for mobile applications. However, they are typically suited for specific types of chemicals and may require frequent filter changes. Ducted hoods offer broader protection and are generally preferred for a wider range of hazardous materials.
