The filter's core strength is its specialized application in two critical areas. It is the established standard for US EPA TCLP Analysis (Method 1311) and is also widely used in biochemistry for the isolation of extremely fine precipitated proteins (such as IgG) and DNA purification. The filter's fine porosity and high loading capacity allow for effective clarification of biochemical and biological fluids, even those containing strongly oxidizing, acidic, or alkaline constituents. With a medium flow rate, it provides a highly efficient and reliable solution for retaining sub-micron particles.
Features:
- Ultra-fine 0.7 µm particle retention for the smallest precipitates
- Specified by the US EPA for the Toxicity Characteristic Leaching Procedure (TCLP 1311)
- Binder-free, pure borosilicate glass for high purity and low background levels
- Ideal for DNA purification, binding, and the collection of extremely fine precipitated proteins
- Medium flow rate and high loading capacity for difficult-to-clarify biochemical fluids
- Suitable for highly oxidizing, acidic, or alkaline constituents
- Available in a comprehensive range of diameters and sheet sizes
