A cylindrical pressure-equalizing funnel without graduation and with a PTFE plug, ASTM, is used in the lab for:
- Chemical Transfer:
- Precise Pouring: Facilitates controlled and precise pouring of liquids.
- Pressure Equalization:
- Avoids Vacuum Formation: Prevents the formation of a vacuum during liquid transfer, ensuring smooth and continuous flow.
- Chemical Handling:
- Compatibility: Designed to handle a variety of chemicals due to its PTFE plug.
- Laboratory Standard:
- ASTM Compliance: Meets ASTM standards, ensuring quality and adherence to industry benchmarks.
- No Graduation:
- Non-Graduated Design: Lacks volume markings, suitable for applications where precise volume measurements are not critical.
- PTFE Plug:
- Chemical Resistance: PTFE plug enhances chemical resistance, making it suitable for a range of laboratory substances.
