Labtron Ductless Fumehood are self-contained ventilation units that filter hazardous fumes and vapors. They don't require external venting, which makes them flexible and easy to install. They are equipped with activated carbon or HEPA filters to trap chemicals, gases, and particulates. They consume less energy than ducted systems by recirculating air within room. Our Ductless Fumehood protects samples and prevents harmful microorganism release in labs.
