Description :
A Dissolution Filter is a laboratory accessory used to separate undissolved particles from the dissolution medium during drug release testing. It ensures accurate sampling of the dissolved drug for analysis, preventing clogging of analytical instruments and maintaining reliable test results.
Features:
Material: Made from stainless steel, nylon, or PTFE, depending on chemical compatibility
Pore Size: Available in various micron sizes (e.g., 0.45 µm, 1 µm, 5 µm) to filter fine particles
Design: Easy-to-fit with dissolution apparatus or sampling syringes
Durability: Corrosion-resistant, reusable (stainless steel) or disposable (nylon/PTFE)
Compliance: Suitable for USP and pharmacopeial dissolution testing standards
Applications:
Pharmaceutical dissolution testing for tablets and capsules
Filtration of dissolved drug solutions prior to HPLC, UV, or spectrophotometric analysis
Ensures accurate, reproducible, and contamination-free sampling
Used in R&D, quality control, and regulatory laboratories
