DynaGard® Filter Tips


Maximum Filtration on the Tip of a Syringe

Uniquely designed with looped hollow fiber membrane, DynaGard maximizes surface area and reduces fouling. The narrow housing design minimizes hold-up volume and enables easy aspiration and dispensing in ampules, test tubes & other small vessels. DynaGard Filters are available with either 0.2 µm hydrophilic mixed cellulose ester (ME) fibers for use with aqueous solutions or 0.2 and 0.45 µm hydrophobic polypropylene (PP) fibers for use with organic solvents and alcohols.

DynaGard Applications:

  • Cold sterilization of aqueous or organic solutions
  • Clarification or filtration of particulates
  • Gas or air filtration
  • Preparation of protein solutions for electrophoresis
