A prepleated filter for use with a conical filter funnel, offers fast filtration and high loading capacity for analysis involving coarse particles or gelatinous precipitates.

• Highest retention among standard filters
• Slow flow rate
• Fine-particle retention
• For qualitative analysis

The filter is wet-strengthened and for normal qualitative application it will not introduce any significant impurities into the filtrate. However, it is not recommended for Kjeldahl nitrogen analysis.
