Whatman PES Channel Filter Plate (Pack of 50)

The Whatman PES (Polyethersulfone) Channel Filter Plate is a filtration device used in laboratory applications, particularly in chromatography and sample preparation processes. Here's a detailed description of the Whatman PES Channel Filter Plate and its features:

1. Material and Filtration Medium:

   • Polyethersulfone (PES): The filter plate is constructed from PES, a thermoplastic polymer known for its excellent chemical resistance and low protein binding properties. PES membranes are suitable for filtering aqueous solutions and biological samples.
   • Filtration Medium: The PES Channel Filter Plate contains PES membranes that provide effective filtration of particulates, microorganisms, and proteins from samples while maintaining high flow rates.

2. Design:

   • Channel Configuration: The filter plate features multiple channels or wells that serve as individual filtration units. These channels allow for the processing of multiple samples simultaneously or in parallel.
   • Uniform Pore Size: The PES membrane in the filter plate typically has a uniform pore size distribution, ensuring consistent and reliable filtration performance.
   • High Throughput: Designed for high sample throughput, making it suitable for applications requiring rapid sample preparation and analysis.

3. Features:

   • Low Binding Properties: PES membranes have low protein binding characteristics, minimizing sample loss and ensuring maximum recovery of target molecules.
   • Chemical Compatibility: The PES material is compatible with a wide range of aqueous solutions and organic solvents commonly used in laboratory applications.
   • Sterile Options: Some PES Channel Filter Plates are available pre-sterilized, making them suitable for sterile filtration applications in cell culture and microbiology.

4. Applications:

   • Chromatography: Used in liquid chromatography (LC) and sample preparation processes for analytical and preparative chromatography applications.
   • Biological Sample Filtration: Suitable for filtering biological samples, cell culture media, buffers, and reagents to remove particulates and microorganisms.
   • Protein Purification: Ideal for protein purification and concentration due to low protein binding properties.
