Microgard™ Liquid Filters - Entegris

1 ADVANCED MATERIALS HANDLINGM icrogard Liquid Filters UPE and nylon Liquid Filters delivering superior cleanliness and high retention capabilities and eliminating potential sources of contamination in bulk chemical systemsMicrogard Filters deliver high-purity solutions for bulk chemicals and bulk chemical distribution systems, and eliminate potential sources of contamination by removing particles and gels at the start of the process. Manufactured in a world-class cleanroom environment, Microgard Filters ensure better initial cleanliness, lower contaminant extractables than polypropylene (PP), and higher chemical compatibility in solvents than polysulfone (PS) or polyethersulfone (PES) of UPE or Nylon MembranesMicrogard Filters are constructed of ultra-high molecular weight polyethylene (UPE) or nylon membranes, depending on the filter .

2 The UPE membrane, utilized in Microgard Plus, Microgard Plus LE, Microgard UPE, and Microgard UPX, promotes high-purity photochemical filtration with an excellent retention rating. With retention ratings as low as 3 nm, Microgard Filters take advantage of some of the tightest membrane technologies available in the market. The asymmetric UPE membrane increases flow and reduces pressure drop , resulting in reduced defects and increased nylon membrane, utilized in Microgard LE Nylon, promotes maximum flow and provides high retention capabilities with its nonsieving retention capabilities. With retention ratings to 10 nm and at twice the thickness of standard nylon Filters , Microgard LE Nylon returns twice the performance and ensures low defectivity in advance chemicals. The hydrophilic nylon membrane elimi-nates prewetting, resulting in reduced chemical usage and less system downtime during filter for a Variety of Chemical ApplicationsMicrogard Filters are optimized for filtration of a variety of chemical applications.
