Customer Questions & Answers
-
Question:
What is the capacity of the United Scientific™ SF149-2000 Conical Separatory Funnel?
Answer: The United Scientific™ SF149-2000 Conical Separatory Funnel has a capacity of 2000 mL or 2 liters. This large capacity makes it ideal for various laboratory applications where substantial volumes of liquid separation are required. Researchers can effectively perform liquid-liquid extraction or separation tasks for experiments ranging from chemical synthesis to biological assays, ensuring they have the appropriate tool for handling larger quantities of solvents. -
Question:
What material is the United Scientific™ SF149-2000 funnel made of?
Answer: This funnel is made of laboratory-grade glass, specifically designed to withstand a variety of chemical reactions. The heavy wall construction enhances durability and resistance to thermal shock. Glass is known for its non-reactivity and ability to maintain purity, making it suitable for sensitive experiments. Laboratories often prefer glass funnels for use with corrosive or volatile substances, where plastic might not provide adequate protection or durability. -
Question:
What are the dimensions of the United Scientific™ SF149-2000 funnel?
Answer: The United Scientific™ SF149-2000 funnel features a conical design which allows for efficient separation of immiscible liquids. While precise dimensions may vary slightly, the funnel's structure ensures a stable base and a wide opening for easy pouring. This design is crucial in facilitating quick and accurate separations in laboratory workflows, particularly when working with larger volumes or when precision in separating layers of liquid is critical. -
Question:
What is the function of the PTFE stockcock in this funnel?
Answer: The PTFE stockcock serves as a reliable stopcock for controlling the flow of liquids in the United Scientific™ SF149-2000 funnel. PTFE, or polytetrafluoroethylene, is a highly inert material that resists chemical reactions, making it ideal for laboratory applications involving aggressive solvents. This feature not only provides precise flow control but also improves the safety of experiments by minimizing the risk of leakage or contamination during liquid transfers. -
Question:
Can this funnel be used for corrosive substances?
Answer: Yes, the United Scientific™ SF149-2000 funnel is suitable for use with corrosive substances, thanks to its heavy wall glass body and PTFE stockcock. The inert nature of both materials ensures that the funnel can withstand harsh chemicals without degrading. This makes it an excellent choice for handling solvents, acids, and bases, facilitating safer operations in chemical laboratories, research facilities, and educational settings. -
Question:
What types of experiments is the United Scientific™ SF149-2000 funnel used for?
Answer: The funnel is commonly used in various chemical and biological experiments, particularly for liquid-liquid extraction processes. PhD candidates and researchers in organic chemistry use it to separate immiscible liquids. It's also beneficial in quality control labs where precise separation of substances is crucial. With its large capacity and reliable flow control, this funnel meets the demands of both routine and advanced experimentation in a laboratory environment. -
Question:
Is the United Scientific™ SF149-2000 funnel compatible with standard lab equipment?
Answer: Yes, the funnel is designed to be compatible with standard laboratory apparatus. The 2440 joints make it suitable for use with various laboratory fittings and supporting equipment. This compatibility is essential for integrative workflows in labs, allowing researchers to seamlessly connect the funnel to distillation setups, separators, or other glassware. Having a funnel that fits standard laboratory equipment facilitates multi-step processes in scientific experimentation. -
Question:
How do I clean and maintain the United Scientific™ SF149-2000 funnel?
Answer: Cleaning the funnel involves rinsing it with appropriate solvents, followed by thorough washing with a laboratory detergent. Avoid using abrasives that can damage the glass. Regular maintenance helps prevent cross-contamination between experiments. Proper care ensures longevity and consistent performance, making it indispensable in maintaining a clean laboratory environment and ensuring accurate results during experiments. -
Question:
What should I consider when using this funnel for separation tasks?
Answer: When using the United Scientific™ SF149-2000 funnel for separation, consider the densities and immiscibility of the liquids involved. Ensure you secure the stopcock properly to avoid leaks during the transfer process. Practicing proper technique, such as allowing sufficient time for the layers to separate, will enhance the effectiveness of your separation tasks. These considerations are critical to achieving accurate and reproducible results in laboratory operations. -
Question:
Where can I buy the United Scientific™ SF149-2000 funnel?
Answer: You can purchase the United Scientific™ SF149-2000 Glass 2000mL Conical Separatory Funnel from Ubuy in Moldova. Ubuy offers a convenient platform for various laboratory supplies, ensuring you have access to quality products for your scientific needs.
UnitedScientific Separatory Funnels Editorial Review
The United Scientific SF149-2000 Glass Conical Separatory Funnel with PTFE Stopcock and Plastic Stopper has received mixed reviews from customers.
