Efficient Liquid Separation with Superior ControlThese separating funnels feature robust glass construction and a PTFE stopcock for excellent chemical resistance and precise flow management. The interchangeable stopper, made of glass or plastic, ensures leak-proof performance during rigorous lab use. Suitable for all major chemical separation tasks, the design offers both pear and conical shapes to facilitate optimal mixing and separation.
Clear, Accurate Measurements and Easy HandlingGraduated marks on the transparent glass enable users to visually monitor volumes with clarity, making precise separations more accessible. The plain stem promotes smooth transfer of separated components, while the ergonomic design offers comfortable handling during pouring or extraction procedures.
Autoclavable and Durable for Lab SafetyManufactured from laboratory-grade glass and featuring an autoclavable build, these funnels can be safely sterilized for repeated use. Their durable construction reduces breakage risk, and the interchangeable stopper provides an added layer of reliability for extended chemical compatibility.
FAQs of Separating Funnels With Sitopcock,Interchangeable Stopper,Conical/Pear Shape With Plain Stem:
Q: How do I use a separating funnel with a sitopcock and interchangeable stopper?
A: Begin by ensuring the stopper and PTFE stopcock are securely in place. Pour the immiscible liquid mixture into the funnel, insert the stopper, and gently shake to mix. Allow the mixture to settle, then drain the lower layer by carefully opening the stopcock, stopping as soon as the interface is reached. The stopper can be easily removed or swapped if needed.
Q: What is the benefit of a PTFE stopcock in these separating funnels?
A: A PTFE (Polytetrafluoroethylene) stopcock offers excellent chemical resistance and smooth operation, minimizing contamination and ensuring precise control over liquid flow. This enhances both safety and accuracy during separation processes, especially with aggressive chemicals.
Q: When should I choose between the conical and pear-shaped designs?
A: Conical-shaped funnels are optimal for rapid, efficient separations, often used when quick settling is needed. Pear-shaped funnels promote thorough mixing and slower separations, making them ideal for more delicate or prolonged extractions.
Q: How do I ensure a leak-proof operation during experiments?
A: Always check that the interchangeable stopper and PTFE stopcock are tightly fitted before use. Inspect the stopper and stopcock regularly for wear or chemical damage, and replace them as necessary to maintain the leak-proof integrity of your funnel.
Q: Where can these separating funnels be sterilized, and are they reusable?
A: These separating funnels are autoclavable and suitable for sterilization in standard laboratory autoclaves. After proper cleaning and sterilization, they are designed for repeated use in laboratory environments.
Q: What are the main laboratory applications for these separating funnels?
A: They are primarily used for liquid-liquid extractions, phase separations, and other applications requiring efficient separation of immiscible chemical solutions. Their compatibility with a variety of chemical reagents makes them essential for general and analytical chemistry labs across industry and academia.
