The filter’s core strength is its powerful retention capability. Although it features a slow flow rate due to its fine porosity, this is the trade-off for capturing the smallest particulates in the qualitative range. Its performance is highly valued for challenging samples, and its use is widely recognized in water and soil analysis. For applications requiring increased throughput, a prepleated (Grade 5V) version is available to provide a significantly improved flow rate and higher loading capacity.
Features:
- Maximum degree of fine particle filtration in the qualitative range (2.5 µm retention)
- Ideal for the clarification of cloudy solutions and suspensions
- Fine porosity for retaining the finest precipitates encountered in chemical analysis
- Widely used in water and soil analysis
- Available in prepleated (Grade 5V) formats for improved flow rate and loading capacity
