One of the primary safety devices in laboratories where chemicals are used is the laboratory fume hood. A well-designed fume hood, when properly installed and maintained, can provide a substantial degree of protection for the researcher, provided its proper use and limitations are understood. Check out the results of our latest fume hood survey.
Top 6 Questions You Should Ask When Buying a Fume Hood
1. Can your lab go ductless? Ductless hoods are a viable solution for most routine laboratory applications. If a total exhaust hood is not an absolute requirement for the process being performed, a ductless solution often makes more sense.
2. What is the hood constructed from, how is it constructed, and how does this affect equipment life cycle? Based on your application, will any of the chemicals being used attack, degrade or physically alter the construction material of the hood? Will the hood stand up to harsh corrosives?
3. What type of safety controls are included in the base cost of the unit?
4. Has the manufacturer/distributor gone through a thorough application review process? Does the suggested filtration make sense?
5. How hard is installation? Will there be a future/potential need to move the hood after it has been installed the first time? Should the hood be portable?
6. What are the capital, installation and operational costs? From the lab manager’s perspective, capital costs are but a fraction of the overall budget. Installation/labor costs and operational costs must be factored in as well.
