Top 6 Questions You Should Ask When Buying a Fume Hood
- Can your lab go ductless? Ductless hoods are a viable solution for most routine laboratory applications.
- What is the hood constructed from and how is it constructed? Will the chemicals you use attack, degrade, or physically alter the material of the hood?
- What types of safety controls are included in the base cost of the unit?
- Has the manufacturer/distributor gone through a thorough application review process? Does the suggested filtration make sense?
- How hard is installation? Will there be a future/potential need to move the hood after initial installation? Should the hood be portable?
- What are the capital, installation and operational costs? From the lab manager’s perspective, capital costs are but a fraction of the overall budget.
