Exceptional Chemical Resistance

Manufactured from high-grade porcelain with a glazed surface, the Buechner funnel is chemically compatible with most laboratory acids, bases, and solvents. This resilience allows for repeated use in rigorous lab environments without degradation or reaction, making it a reliable choice for multi-step and sensitive filtration procedures.

Versatile Filtration Performance

The funnel supports both vacuum and gravity filtration processes, which makes it highly adaptable for different laboratory applications. Its flat perforated filter plate ensures even distribution of filter media, promoting efficient and uniform separation of solids from liquids. This versatility is crucial for effective sample preparation in scientific research.

FAQs of Funnel Buechner:

Q: How do you use the Buechner funnel for vacuum and gravity filtration?

A: Place appropriate filter paper on the flat perforated plate, moisten it to ensure a good seal, then connect the funnel to a vacuum system for vacuum filtration or simply allow gravity to draw the liquid through if using gravity filtration. This flexibility supports a variety of laboratory needs.

Q: What are the main benefits of using a glazed porcelain Buechner funnel?

A: The glazed porcelain construction offers excellent chemical resistance, ease of cleaning, durability, and the ability to withstand repeated autoclaving at 121C. This ensures long-term usability and reliable filtration, even with harsh chemicals.

Q: When should the Buechner funnel be sterilized, and what is the best method?

A: The funnel should be sterilized before use in sterile or sensitive applications. Autoclaving at 121C is recommended, as the porcelain and glazed surfaces withstand the heat and pressure, ensuring complete sterilization.

Q: Where is the Buechner funnel most commonly used?

A: This funnel type is primarily utilized in chemical, biological, and analytical laboratories for tasks requiring precise filtration, such as separating solids from liquids in chemical syntheses or sample preparations.

Q: What capacities and sizes are available for the Funnel Buechner?

A: The funnel comes in multiple capacities, commonly 100 ml, 250 ml, and 500 ml, with diameters typically ranging from 9 to 18 centimeters and heights between 13 and 20 centimeters, accommodating various sample volumes.

Q: Is the Funnel Buechner reusable and easy to maintain?

A: Yes, it is designed to be reusable. Its glazed porcelain surface (except the rim and perforated plate) facilitates easy cleaning and resists chemical attack, ensuring longevity with proper maintenance.

Q: What quality and safety standards does the Buechner funnel comply with?

A: The funnel meets standard laboratory quality requirements, ensuring reliable performance and safety during routine and specialized applications in laboratory settings.
