Whatman Polypropylene Filter Funnel Plate

The "Whatman Polypropylene Filter Funnel Plate" is a laboratory filtration device designed for sample preparation and filtration applications. Here's a detailed description of this filter funnel plate and its features:

1. Material:

   • Polypropylene (PP): The filter funnel plate is made of polypropylene, a thermoplastic polymer known for its chemical resistance, durability, and affordability. PP is compatible with a wide range of solvents and chemicals commonly used in laboratory settings.

2. Design and Features:

   • Plate Configuration: The filter funnel plate typically consists of a flat, circular plate with integral filter funnel(s) attached. The plate may have multiple funnel units arranged in an array for simultaneous filtration of multiple samples.
   • Integral Funnel: Each funnel on the plate is designed with a wide mouth for easy sample loading and a stem that fits securely into the receiving vessel or collection container.
   • Chemical Resistance: The PP material provides excellent resistance to acids, bases, organic solvents, and other chemicals encountered in laboratory filtration processes.
   • Autoclavable: Many PP filter funnel plates are autoclavable, allowing for sterilization and reuse in laboratory and healthcare settings.
   • Disposable or Reusable: Depending on the design and intended use, PP filter funnel plates may be disposable for single-use applications or reusable after proper cleaning and sterilization.

3. Applications:

   • Sample Filtration: Used for vacuum-assisted filtration of liquids to separate solids or particulates from solutions or suspensions.
   • Microbiological Testing: Suitable for microbiological analysis, including sample preparation for microbial culture and enumeration.
   • Environmental Monitoring: Used in water quality testing and environmental monitoring to filter particulates and contaminants from environmental samples.
   • Food and Beverage Analysis: Applied in food and beverage industries for sample preparation and quality control testing.

4. Advantages:

   • Versatile Filtration: The filter funnel plate allows for efficient and simultaneous filtration of multiple samples, saving time and labor in laboratory workflows.
   • Chemical Compatibility: PP material resists chemical attack, ensuring compatibility with a wide range of sample types and solvents.
   • Cost-Effective: PP filter funnel plates are often more affordable than glass or stainless steel alternatives, making them suitable for routine laboratory use.
   • Easy Handling: The lightweight and durable PP construction facilitates easy handling and minimizes the risk of breakage compared to glassware.

5. Packaging and Sizes:

   • PP filter funnel plates are available in different sizes and configurations, including single-plate and multi-well formats, to accommodate various sample volumes and throughput requirements.
   • They may be supplied individually or in packs, providing flexibility for laboratory procurement and usage.
