Cannula Filters | Filter Frits | Filter Tips

When a filter is required for clean sample collection andequipment protection, POREX Dissolution Filters are theporous design solutions chosen by a broad spectrum ofdissolution equipment manufacturers to meet individualdesign and performance specifications. 

POREX Dissolution Filters exemplify the critical designstandards and precision molding required for today’stechnological products. POREX Makes It Possible.

  • Moldable porous plastic for design flexibility
  • Strong and durable to withstand automated assembly equipment and resist breakage
  • Resilient for good compression fit
  • Chemically-resistant

Why Choose POREX Dissolution Filters?

POREX Dissolution Filters help deliver precision, accuracy and reliability to meet the most challenging dissolution applications. The unique structural characteristics of ourlightweight, porous materials result in design flexibility and long-term value advantages.Fabricated from polyethylene (PE) and ultra-high molecular weight polyethylene(UHMWPE), POREX Dissolution Filters are available in standard sheet products, disks orcustom configurations. POREX Dissolution Filters provide superior resiliency for a goodcompression fit and a strong, durable construction to withstand the rigors of automatedequipment assembly. Additionally, our media is chemically-resistant to withstand mostacids and bases and has an excellent appearance for a quality image. 

Dissolution testing is a critical performance measurement in pharmaceutical tablet andcapsule products. Used to determine the bioequivalence and absorption in the humanbody with in vitro-in vivo correlations, dissolution testing is conducted in apparatusesunder a variety of test conditions according to the nature of the dosage form.Dissolution testing equipment removes, filters and collects sample aliquots for furtheranalysis. POREX Dissolution Media - cannula filters, filter frits and filter tips - are usedto help filter contaminants and facilitate testing. 

Cannula Filters

Manufactured from porous UHMWPE, POREX® Cannula Filters areused on the end of a sampling cannula and feature a large surfacearea and optimized flow rate for an ideal choice in applications witha high presence of particulates. POREX Cannula Filters are availablein 1, 4, 5, 10, 20, 35 and 70 micron sizes.


Filter Frits

Manufactured from porous PE, POREX® Filter Frits are circular filtersused with low-dimension sample probes in applications where it is important to keep the filtration process outside of the vessel. POREX Filter Frits are available in 10 and 45 micron sizes.

 

Filter Tips

Manufactured from porous PE, POREX® Filter Tips are used with low quantities of particulates and flow at the filter bottom. POREXFilter Tips are available in 2, 5, 10, 20 and 45 micron sizes and can be used on sample cannulas with 1/6” diameter
