The Isodry dental isolation system provides two channels of continuous hands-free vacuum suction. The strong, ultra lightweight Isodry Control Head is constructed of titanium and weighs only 68 grams. Dual vacuum simultaneously allows you to focus suction in either the upper or lower quadrant, giving you better control of moisture and oral humidity. The Isodry vacuum hose measures 1.8 metres long, is made of silicone, and connects easily to most standard high volume suction units.
