Sterile Millex® syringe filters you can trust. Research Applications: Sterile filtration of tissue culture media and additives / Buffers / DMSO / Biological solutions.
Filtration is used in dissolution testing to end the dissolution process and prepare the sample for HPLC analysis. This page discusses the importance of filtration and utility of hydrophilic PTFE Millex® syringe filters in dissolution testing.
In vitro dissolution testing is used to characterize drug compounds throughout their development. In early drug development it is used to support the choice of a particular formulation. During drug production it is a critical component of the quality control process and is used to assess the changes in manufacturing processes or formulation. In order for dissolution results to be meaningful at each stage, the test and the process need to be reliable, consistent, predictive and accurate.
Syringe membrane filter selection and validation methods to assess analyte loss due to membrane filter adsorption in pharmaceutical quality control (QC) testing.
Millex® hydrophilic PTFE syringe filters boast broad chemical compatibility and are HPLC-certified, guaranteeing low extractables. With their robust performance, these filters can be used for a variety of samples without the risk of membrane failure or sample contamination.
