Betafine PPG series filter capsule is an absolute rated, graded porosity multi-layer 100% polypropylene pleated nonwoven filter with advanced pleat technology (APT). APT increases the usable surface area while allowing the product to be offered in standard sizes. All polypropylene material offers excellent chemical compatibility with many solvents. 3M combines performance enhancing features into Betafine PPG series filter capsules. Their advanced pleat technology (APT) construction provides up to 50% more filter media (surface area) than their standard pleated filters. This design technology maximizes the useful surface area by maintaining open flow paths between media pleats. To increase the useful surface area and filter life, we designed Betafine PPG series filter capsule so the pleating design and media support materials work together to provide enhanced flow characteristics. The filter media itself is made using absolute rated, graded density media. Each Betafine PPG filter capsule is shipped with a certificate of quality detailing the product attributes and qualification testing to help support your documentation requirements. The graded density media structure we incorporate in Betafine PPG filters removes particles sequentially by size - the larger particles by the more open, outer layer and the smaller particles by the tighter, inner layer. The outer layer in essences acts as a pre-filter to the inner layer, which then provides the absolute removal specified by the filter rating. This configuration effectively spreads the contaminant throughout the depth of the filter, resulting in high contaminant capacity. All polypropylene construction is used in order to provide broad chemical compatibility. Betafine PPG filters have low extractable levels and are well-suited for process filtration of a wide range of fluids. Betafine PPG filters can be used for general pre-filtration, clarification or as a final filter in appropriate applications. All product components comply with united states pharmacopeia (USP) class VI 70 deg c biological reactivity, in vivo. Betafine PPG series filter capsules serve a broad range of pre-filtration and clarification applications in pharmaceutical, biological and bioprocess manufacturing where economy and reliability are critical.
