Customer Questions & Answers
-
Question:
What materials are used in the EISCO Dropping Funnel?
Answer: The EISCO Dropping Funnel is primarily made from borosilicate glass, known for its high thermal resistance and durability. It features a PTFE (Polytetrafluoroethylene) key stopcock that ensures secure and precise control over flow rates. This combination allows for reliable chemical handling, making it ideal for laboratory settings. The open-top design facilitates easy filling and cleaning, while the cylindrical shape promotes accurate pouring. -
Question:
What is the capacity of this dropping funnel?
Answer: The EISCO Dropping Funnel has a capacity of 500ml, which makes it suitable for various laboratory applications. This size is perfect for performing titrations, adding reagents gradually, or transferring liquids in precise amounts. The sufficiently large capacity minimizes the need for frequent refills during experiments or when working on extensive projects, adding to the overall efficiency. -
Question:
How does the PTFE key stopcock work?
Answer: The PTFE key stopcock provides a reliable method to control the flow of liquids from the funnel. It operates smoothly, allowing users to start and stop the flow accurately. The chemical resistance of PTFE also prevents corrosion or damage from reagents, making it a crucial feature for anyone working with caustic or volatile solutions. This design ensures users can conduct experiments without the risk of spills or inaccuracies. -
Question:
Is the EISCO Dropping Funnel suitable for a variety of chemicals?
Answer: Yes, the EISCO Dropping Funnel is compatible with a wide range of chemicals. The borosilicate glass construction can withstand thermal fluctuations and various chemical compositions without compromising integrity. This versatility makes it an essential tool in laboratories, especially for chemists dealing with solvents, acids, and bases. Its design also minimizes the risk of chemical reactions that could occur in less compatible materials. -
Question:
What are the maintenance requirements for this funnel?
Answer: Maintaining the EISCO Dropping Funnel is straightforward. After use, it should be rinsed thoroughly with appropriate solvents to remove any residual chemicals. The borosilicate glass can be cleaned with standard laboratory cleaners, while the PTFE stopcock can occasionally be lubricated for a smooth operation. Proper care ensures longevity and consistent performance, which is crucial for accurate lab work. -
Question:
Can this funnel be used in high-temperature applications?
Answer: Yes, the EISCO Dropping Funnel is suitable for high-temperature applications due to its borosilicate glass construction. This type of glass can withstand significant temperature changes without breaking or deforming. It is ideal for processes that involve heating liquids or when working near heat sources, ensuring that users can confidently carry out their experiments. -
Question:
What is the significance of the cylindrical shape?
Answer: The cylindrical shape of the EISCO Dropping Funnel facilitates uniform liquid flow and easy pouring. This design minimizes the formation of air pockets, allowing for a consistent discharge of liquids. Moreover, the open top allows for easy filling without spills. This shape is beneficial when precision is paramount, such as in titrations or when dealing with small quantities of reagents. -
Question:
Is this dropping funnel ungraduated?
Answer: Yes, the EISCO Dropping Funnel is an ungraduated model, designed without measurement markings. This characteristic makes it ideal for applications where exact volume measurement is unnecessary, focusing instead on the controlled flow of liquids. Users typically rely on other graduated vessels for precise volume measurements, making this funnel perfect for operations that prioritize direct liquid transfer. -
Question:
Where can I buy the EISCO Dropping Funnel in New Zealand?
Answer: You can buy the EISCO Dropping Funnel, 500ml - PTFE Key Stopcock through Ubuy in New Zealand. Ubuy is known for providing a wide range of laboratory equipment and supplies, ensuring you can find quality products like this funnel and have them delivered directly to your address. -
Question:
What are practical applications of using this dropping funnel?
Answer: Practical applications of the EISCO Dropping Funnel include titrations, where precise amounts of reagents need to be delivered drop by drop. It is also useful for controlled liquid transfer in experiments that require strict adherence to chemical quantities. Moreover, this funnel is ideal for researchers working with sensitive reactions that demand accurate control over the addition of liquids, preventing spills or overflows.
EISCO Lab Funnels Editorial Review
The Dropping Funnel by Eisco Labs offers a convenient and efficient solution for percolation tinctures. Made of borosilicate glass, this cylindrical funnel has a capacity of 500ml and features a PTFE key stopcock for easy control of liquid flow. However, customer reviews indicate a major flaw in the design. The plastic nut holding the stopcock in place has a tendency to break after only a few uses, rendering the entire funnel useless. This is a significant issue that Eisco Labs should address in order to provide a more durable and reliable product.
