Faster Sample Processing Compared to Manual Syringe Filtration
Using the steps indicated (below the table*), sample processing time was compared between the Samplicity® G2 filtration system and manual syringe filtration, processing eight samples at a time, using a variety of Millex® device types** and test solutions. The Samplicity® G2 filtration system afforded time savings in all cases tested.

**Refers to Millex® Filters for the Samplicity® G2 System. Specific filters tested were 0.22 μm Durapore® PVDF, 0.45 μm Durapore® PVDF, 0.22 μm Millipore Express® PLUS PES, 0.45 μm Millipore Express® PLUS PES, 0.20 μm nylon, and 0.45 μm nylon.
For Optimum Speed Advantage, Choose Millex Samplicity® Filters
Overall time savings using Samplicity® filtration system compared to syringe filtration.To compare the speed of the Samplicity® system compared to syringe filtration, either four or eight 1.0 mL samples of 1% Pepto-Bismol were filtered by 15 timed users, either through hydrophilic polytetrafluoroethylene (PTFE) Millex syringe filters with a 10 mL syringe, or through 0.45 µm hydrophilic PTFE Millex Samplicity® membrane filters using the Samplicity® filtration system.
Pre-launch Device Disclaimer: The information presented is based on preliminary development results. Device performance in specific applications may be different.
The Samplicity® Filtration system enables higher yields for small sample volumes: low holdup volume enables you to do more analyses with each precious sample.
