The enclosure allows full access to the balance while keeping the effects of drafts and air movement to a bare minimum for highly accurate weighing. Constructed of clear acrylic with solid aluminum framing, the enclosure allows full light penetration from all angles. When natural light is inadequate we can supply a light mounted outside the enclosure. The front hinged panel, designed for easy access, is made from a durable clear polycarbonate material. A port for electrical line cord is provided at the rear of the enclosure.

This ductless fume hood features a variable speed blower allows continuous adjustment of airflow and face velocity. The unit is supplied with a HEPA Filter which is designed to remove particles down to 0.3 microns in size at 99.99% efficiency. If you are working with gross particulate, you may want to add a pre-filter in combination with the HEPA. The pre-filter removes gross particulate from the air, and prevents premature clogging of the HEPA filter, thereby extending its life. Optional carbon filters are available for adsorption of vapors.
