产品名称：Pallflex Emfab Filters, Pall Life Sciences 7221

Product Category Description:

These filters are ideal for diesel exhaust and stack emission testing. Filters consist of pure borosilicate glass microfibers reinforced with woven glass cloth and bonded with PTFE. These filters feature low air resistance for use in critical aerosol sampling tests that demand filter purity and nonhygroscopic properties, such as diesel exhaust, stack emission control, and ambient air monitoring for particulate concentration. Every filter is flushed with deionized water to remove water-soluble residue. The filters also withstand folding for weighing and transport.

Ordering Information: Also available in 20.3 x 25.4cm sheets.
