Choose the original IOM Inhalable Sampler for optimal performance! The IOM is a gold standard sampler in the industry. A convenient removable filter cassette that is weighed before and after sampling as a single unit makes the IOM ideal for gravimetric determinations and eliminates wall losses. IOM meets several U.S. and international standards for inhalable particulate and bioaerosols. Use IOM with a personal sample pump at 2 L/min; SKC recommends an AirChek Series Sample Pump. Choose the lightweight plastic IOM for gravimetric sampling or autoclavable stainless steel for chemical analysis and bioaerosol sampling. When used with MultiDust Foam Discs, IOM can sample respirable and inhalable particulate simultaneously.
