Precision Chemical DeliveryDropping funnels with cylindrical design and a PTFE key rotaflow allow for meticulous dispensing of reagents in laboratory procedures. The unique screw-type control ensures gradual, dropwise addition of liquids, reducing the risk of overshooting and enhancing experimental reproducibility. With clearly marked graduations, users can measure and transfer solutions accurately, making this instrument ideal for titrations, extractions, and other controlled addition processes.
Superior Chemical Resistance and UsabilityConstructed from borosilicate glass and equipped with a PTFE key, the funnel provides excellent resistance to most acids and solvents. The reusable design not only stands up to repeated use but also permits easy cleaning for rigorous laboratory settings. Its compatibility with common lab setups and customizable ground glass joints makes integration seamless, ensuring efficient workflow for both teaching and research environments.
FAQs of Dropping Funnels Cylindrical With Screw Type PTFE Key Rotaflow:
Q: How do I operate the Dropping Funnels Cylindrical With Screw Type PTFE Key Rotaflow?
A: To operate the dropping funnel, secure it in your laboratory setup using the ground glass joint. Fill the funnel with your reagent, ensure the PTFE key stopcock is closed, and then gradually open the screw mechanism to deliver liquid dropwise as required by your experiment.
Q: What chemicals are compatible with this dropping funnel?
A: The funnel is made of borosilicate glass and features a PTFE key, offering excellent resistance to most laboratory acids, solvents, and chemicals commonly used in research and teaching labs.
Q: When should I use a dropping funnel with a PTFE key stopcock?
A: This funnel is ideal when controlled addition or titration of a reagent is necessary, such as during sensitive chemical reactions, extractions, or when maintaining precise reaction rates is critical.
Q: Where can the funnel be used in the laboratory?
A: The dropping funnel fits standard laboratory apparatus and is suitable for use in chemical, educational, and research laboratories, including school, college, and industrial research settings.
Q: What is the process for cleaning and maintaining the dropping funnel?
A: After each use, wash the funnel thoroughly with appropriate laboratory detergents and rinse with distilled water. The screw-type PTFE key can be removed for detailed cleaning, ensuring the funnel is ready for reuse and maintains optimal operation.
Q: What are the primary benefits of using a PTFE key rotaflow dropping funnel over traditional designs?
A: The PTFE key ensures a chemically resistant, leak-proof, and easily operable stopcock, providing safer handling and more precise control compared to glass stopcocks or sintered discs.
