A cylindrical pressure-equalizing funnel without graduation and with a PTFE plug, ASTM, is used in the lab for:

  1. Chemical Transfer:
    • Precise Pouring: Facilitates controlled and precise pouring of liquids.
  2. Pressure Equalization:
    • Avoids Vacuum Formation: Prevents the formation of a vacuum during liquid transfer, ensuring smooth and continuous flow.
  3. Chemical Handling:
    • Compatibility: Designed to handle a variety of chemicals due to its PTFE plug.
  4. Laboratory Standard:
    • ASTM Compliance: Meets ASTM standards, ensuring quality and adherence to industry benchmarks.
  5. No Graduation:
    • Non-Graduated Design: Lacks volume markings, suitable for applications where precise volume measurements are not critical.
  6. PTFE Plug:
    • Chemical Resistance: PTFE plug enhances chemical resistance, making it suitable for a range of laboratory substances.
