Whatman PTFE Channel Filter Plate (Pack of 50)

The Whatman PTFE (Polytetrafluoroethylene) Channel Filter Plate is a specialized filtration device used in laboratory applications for various filtration and sample preparation processes. Here's a detailed description of the Whatman PTFE Channel Filter Plate and its features:

1. Material and Filtration Medium:

   • Polytetrafluoroethylene (PTFE): The filter plate is constructed using PTFE, a highly inert and chemically resistant material known for its non-stick properties and compatibility with a wide range of chemicals and solvents.
   • Filtration Medium: The PTFE Channel Filter Plate contains PTFE membranes that provide efficient filtration of liquids and gases while maintaining high chemical resistance.

2. Design:

   • Channel Configuration: The filter plate features multiple channels or wells that serve as individual filtration units. These channels allow for the simultaneous filtration of multiple samples or fractions.
   • Chemical Resistance: PTFE membranes are resistant to acids, bases, organic solvents, and other aggressive chemicals, making them suitable for challenging filtration applications.
   • Hydrophobic Properties: PTFE membranes are hydrophobic, repelling water and allowing for efficient filtration of organic solvents and non-aqueous solutions.

3. Features:

   • Non-Stick Surface: PTFE membranes have a non-stick surface, reducing the risk of sample adhesion and ensuring maximum recovery of filtrate.
   • High Temperature Resistance: PTFE material can withstand high temperatures, making it suitable for filtration processes requiring elevated temperatures.
   • Low Extractables: PTFE membranes exhibit low extractables, minimizing interference with sensitive analytical methods.

4. Applications:

   • Chemical Filtration: Used for filtration of aggressive chemicals, acids, bases, and organic solvents in laboratory settings.
   • Air and Gas Filtration: Suitable for filtering air and gases due to its hydrophobic nature and chemical resistance.
   • Sample Preparation: Ideal for sample preparation in analytical chemistry, environmental testing, and pharmaceutical applications requiring clean and particle-free samples.

5. Packaging:

   • The Whatman PTFE Channel Filter Plate is typically available in packs containing multiple units (e.g., pack of 50), providing convenience and cost-effectiveness for laboratory filtration needs.
   • Each plate is designed for single-use applications to prevent cross-contamination and ensure consistent filtration performance.
