HDC metblown media is constructed of polypropylene fibers in a depth structure which provides high surface area and increased particulate holding capacity.

The proprietary manufacturing process used to produce melt blown media allows for the creation of multiple filtration zones with internal voids that result in the efficient use of the depth structure. These function similarly to asymmetric membranes, capturing particulate within the structure ensuring efficient clarification of viscous samples and lysates. The concern over fiber shedding is also minimized due to the continuous nature of the fibers.
