Customer Questions & Answers
-
Question:
What is a conical separatory funnel used for?
Answer: A conical separatory funnel is primarily used for separating immiscible liquids, allowing for effective liquid-liquid extraction. The funnel's shape enables easier phase separation, as the denser liquid settles at the bottom. This is beneficial in various processes such as chemical extractions, where distinct layers of solvents are present. For instance, in a lab procedure, a chemist can separate organic solvents from aqueous solutions without contamination. -
Question:
Why is borosilicate glass preferred for laboratory glassware?
Answer: Borosilicate glass is favored in laboratories due to its high resistance to thermal shock and chemical corrosion. This material can withstand sudden temperature changes, making it suitable for heating and cooling applications. For example, if you're conducting heating experiments, using borosilicate glass minimizes the risk of breakage. This durability makes it a reliable choice for extended use in various scientific applications, ensuring safety and longevity. -
Question:
What kind of joints do the 2429 joints refer to in the funnel?
Answer: The 2429 joints in the funnel refer to a standardized joint type that facilitates a secure connection with other lab apparatus, ensuring a leak-proof seal during experiments. This compatibility is crucial when connecting the funnel to a flask or other glassware, allowing for efficient transfer and separation of liquids. As an example, this standard joint type allows for versatile use in various setups, optimizing laboratory workflows. -
Question:
What is the benefit of having a PTFE stopcock in a separatory funnel?
Answer: A PTFE (Polytetrafluoroethylene) stopcock provides excellent chemical resistance and a smooth operation when opening and closing the flow of liquid. This feature minimizes the risk of leakage and allows for precise control over liquid transfer. In practical applications, such as titration or multistep separation processes, a reliable stopcock ensures that you can accurately manage the flow of substances without contamination or loss, enhancing the overall effectiveness of the experiment. -
Question:
How should I clean and maintain my borosilicate glass separatory funnel?
Answer: To clean a borosilicate glass separatory funnel, rinse it with distilled water immediately after use to prevent residue buildup. For stubborn residues, use a mild detergent and a soft brush or sponge. Avoid abrasive materials, as they can scratch the surface. Proper maintenance involves regular inspections for cracks and chips; if detected, do not use the funnel. Keeping the glassware clean will resonate in your experiment results, providing accurate and reliable data. -
Question:
Can this funnel be used for both laboratory and field applications?
Answer: Yes, the stonylab Borosilicate funnel is versatile enough for both laboratory and field applications. Its robust design allows it to perform well under various conditions, making it suitable for site testing or research involving organic solvents. For example, scientists conducting environmental surveys can efficiently separate liquids in the field, ensuring that their materials maintain integrity regardless of location, thus maximizing reliability of results. -
Question:
What safety precautions should I consider when using a separatory funnel?
Answer: When using a separatory funnel, always wear appropriate personal protective equipment (PPE), such as gloves and safety goggles, to shield against chemical splashes. Additionally, ensure the workspace is well-ventilated and that you are familiar with the chemicals being used. Since some solids can settle, gently swirl the funnel to mix contents before separating. Understanding the specific properties of your materials will lead to safer and more accurate experimental results. -
Question:
What is the maximum temperature this funnel can withstand?
Answer: Borosilicate glass can typically handle temperatures up to approximately 500 degrees Fahrenheit (260 degrees Celsius). This high thermal stability allows the funnel to be used in various heating applications without risk of breaking. For instance, if you are running reactions that require elevated temperatures, using this funnel ensures that it maintains structural integrity, enabling safe continuation of experiments without needing to switch glassware. -
Question:
How does the design of a conical separatory funnel contribute to its efficiency?
Answer: The conical shape of a separatory funnel allows for optimal phase separation of liquids, as it provides a larger surface area for the liquids to interact. This design reduces the amount of time required to separate mixtures, making it efficient for quick analyses. In practice, during extraction procedures, the conical shape ensures that less residual liquid remains trapped, maximizing the yield of the desired compound. -
Question:
Where can I buy the stonylab Borosilicate Glass 500 ml Heavy Wall Conical Separatory Funnel with 2429 Joints and PTFE Stopcock in Samoa?

Ubuy offers a convenient online shopping experience, providing various options for importing this quality laboratory glassware directly to your location in Samoa, ensuring that you have access to essential science equipment.
stonylab Separatory Funnels Editorial Review
The StonyLab Borosilicate Glass 1000 ml Heavy Wall Conical Separatory Funnel includes a 2429 joint and PTFE stopcock. Customers report that it is suitable for phase separating unleaded fuel, and can be used with hot water. The funnel has a 24/29 joint, a 3mm bore hole for draining, and an overall length of 15.74in (40cm). The tension on the stopcock is adjustable. Customers have had positive experiences with this funnel, finding it sturdy and leak-free - gravity has had little effect on it after almost a year of daily use. However, some customers have reported poor craftsmanship - a stress fracture was discovered upon opening one package, which then shattered with minor tapping. Additionally, some customers report a cheap quality of glass which broke too easily at the valve.
