Asahi Kasei Bioprocess has developed a second generation AGPTS-II to streamline and automate the post-use gold particle test for Planova N series filters. The AGPTS-II can execute the entire test in less than 25 minutes and is available in single-filter and multi-filter configurations. Save Time, Reduce Risk The gold particle test (GPT) is a post-use integrity test for Planova filters which confirms no shift in pore size distribution after virus filtration. Diluted integrity test solution is pushed through the filter, and an in-line visual spectrometer measures the absorbance of the permeate fraction. The control unit automatically calculates the gold particle LRV and produces a filter pass/fail result without the need for offline analysis. Significant time savings are realized. Multi-Filter AGPTS-II can automatically test multiple Planova filters sequentially. They are available in 5-filter, 6-filter and 10-filter configurations, and are ideal for processes which utilize 3 or more Planova filters per batch, or in facilities that use more than 100 Planova filters per year.
