Whatman GV100/1 500 ml Funnel PTFE Ring

The Whatman GV100/1 500 ml Funnel with PTFE Ring is a laboratory filtration funnel designed for use in chemical and biological applications. Here's a detailed description of this funnel and its features:

1. Functionality:

   • Filtration: The GV100/1 funnel is used for vacuum filtration applications to separate solids from liquids. It is compatible with various filter papers for different filtration needs.
   • Chemical Resistance: Constructed from high-quality materials like borosilicate glass or polypropylene, providing excellent chemical resistance to a wide range of solvents and chemicals.
   • PTFE Ring: The PTFE (Polytetrafluoroethylene) ring around the funnel's stem ensures a tight and secure seal when connecting the funnel to the filtration apparatus, preventing leakage during vacuum filtration.

2. Design:

   • 500 ml Capacity: The funnel has a capacity of 500 ml, suitable for handling moderate volumes of liquids during filtration processes.
   • Wide Base: The wide base of the funnel provides stability when placed on support stands or filtration apparatus.
   • Ribbed Exterior: Some models may feature a ribbed exterior for improved grip and handling.

3. Features:

   • Compatibility: The GV100/1 funnel is compatible with standard laboratory vacuum filtration setups, including Buchner funnels and vacuum flasks.
   • Ease of Use: Designed for easy assembly and disassembly, allowing for quick setup and cleaning between filtration processes.
   • Versatility: Suitable for a wide range of laboratory applications, including sample preparation, gravimetric analysis, and particulate testing.

4. Applications:

   • Laboratory Filtration: Used in chemistry, biology, and environmental science laboratories for separating solids from liquids in various samples.
   • Particulate Analysis: Ideal for filtering particulate matter from liquids for further analysis and characterization.
   • Sample Concentration: Useful for concentrating samples by removing excess liquid through vacuum filtration.

5. Advantages:

   • Chemical Resistance: Resistant to a wide range of chemicals and solvents commonly used in laboratory applications.
   • Reliable Seal: The PTFE ring ensures a tight seal, minimizing the risk of leakage during filtration.
