What is Filtration?

The filtration process involves passing liquids and gases through the pores of a membrane, referred to as a filter, to separate solids from liquids. Filtration can take many forms, including: mechanical filtration, microfiltration, ultrafiltration, nanofiltration, reverse osmosis, dialysis, and electrodialysis

What is Ultrafiltration?

Ultrafiltration (UF) is a membrane filtration technique that uses hydrostatic pressure to push liquids against a semipermeable membrane with tiny pores. This process effectively removes particles and contaminants based on size, making it an ideal solution for water treatment and biotechnology applications. In water treatment, UF eliminates particulate matter, pathogens, and viruses, while also ensuring a chemical-free process. In biotechnology, UF is instrumental in protein purification, cell harvesting, vaccine production, and enzyme recycling. By leveraging its precision and flexibility, UF plays a crucial role in various industries, providing a reliable and efficient solution for separating and purifying substances.

Filter-bond™ E-Series

Filter-bond™ Epoxy by Hapco, Inc.

As part of this series, Hapco offers a line of flexible and rigid materials compatible with MiniFILTM and RapidFILTM dispensing machines applicable for potting and encapsulating filter media for various applications.

  • Filter-bond™ E-3503: It has high viscosity (40,000 cps) and is ideal for low wicking. It is a two-component, semi-rigid, extremely tough elastomer commonly used for potting and sealing filter media.
  • Filter-bond™ E-3505: Also typically used for sealing filter media, this has excellent bonding characteristics and high viscosity (50,000 cps) to prevent wicking.
  • Filter-bond™ E-3568: This product performs well in applications such as pre-potting filter endcaps, flexible gasketing, ultrafiltration, and filtration. It is ideal for pre-potting filters for easy cutting or trimming.

Filter-bond™ R-Series

  • Filter-bond™ R-30-6 Series: A three-part potting and adhesive system is designed for bonding or potting ultrafiltration products. The adhesive and potting systems do not contain carcinogens or substances that cause mutation.
  • Filter-bond™ R-36: With its uses in various ratios, including 2:1 to 1:1 by volume or weight, it is an ideal product for production and field use. Our line of polymer adhesive bonds metals, plastics, ceramics, wood, fabrics, and canvas.
  • Filter-bond™ R-37-38: This structural adhesive provides excellent adhesion to both similar and dissimilar substances while chemically resistant. It was developed specifically to bond filter media in ultrafiltration applications.
