1000mL Pear-Shaped Plastic Separatory Funnel GUOHUIZHANG PTFE Stopper

Description

Product Overview

The 1000mL pear‑shaped plastic separatory funnel from GUOHUIZHANG is engineered for high‑performance liquid handling in modern laboratories. Constructed from premium-grade polypropylene, the funnel offers excellent chemical resistance to acids, bases, and organic solvents, ensuring long‑term durability even under rigorous cleaning cycles. The distinctive pear shape provides a wide opening for easy sample loading and a narrow spout that delivers precise control over liquid flow, reducing waste and improving reproducibility. Equipped with a PTFE (polytetrafluoroethylene) stopper, the funnel creates a secure, leak‑free seal that can withstand a wide temperature range, making it suitable for both ambient and heated processes. The transparent body allows quick visual assessment of phase boundaries, while the graduated markings enable accurate volume measurements down to the milliliter. Overall, this funnel combines robust material properties, thoughtful ergonomics, and reliable sealing technology to meet the demanding needs of chemistry, biology, and research environments.

Usage

This separatory funnel excels in a variety of laboratory applications. In organic synthesis, it facilitates efficient separation of immiscible liquids, allowing chemists to isolate desired products with minimal cross‑contamination. In analytical chemistry, the funnel supports sample preparation steps such as liquid‑liquid extraction, where precise volume control and clean separation are critical for accurate results. Biological laboratories benefit from the funnel’s chemical resistance when handling aqueous buffers, enzyme solutions, or cell culture media, ensuring that no leaching or degradation occurs. The funnel is also ideal for educational settings, providing students with a reliable tool for hands‑on experiments that demonstrate phase separation principles. Its user‑friendly design makes it suitable for both seasoned researchers and newcomers, and the PTFE stopper’s easy‑twist mechanism enables quick opening and closing without compromising safety. Whether used in a high‑throughput research facility or a small teaching lab, this funnel delivers consistent performance across a broad spectrum of tasks.

FAQ

What types of chemicals can the funnel safely handle?

The funnel is made from polypropylene, which is resistant to most acids, bases, and organic solvents. It is suitable for common laboratory reagents such as hydrochloric acid, sodium hydroxide, ethanol, and many other solvents. However, for highly aggressive chemicals like strong oxidizers or fluorinated solvents, consult the material compatibility chart or contact our support team.

Can the PTFE stopper be replaced if it wears out?

Yes, the PTFE stopper is designed as a replaceable component. Replacement stoppers are available as part of our accessory line, and installation is straightforward: simply twist the old stopper out and insert the new one, ensuring a snug fit. This extends the lifespan of the funnel and reduces overall cost.

Is the funnel suitable for use in temperature‑controlled experiments?

The polypropylene body can tolerate temperatures from -20 °C to 120 °C, making it appropriate for many heated or cooled procedures. The PTFE stopper also maintains its sealing properties across this temperature range, allowing the funnel to be used in reflux setups, cooling condensations, or low‑temperature extractions.

How do I clean and maintain the funnel?

After each use, rinse the funnel with an appropriate solvent (e.g., water for aqueous solutions, ethanol for organic residues) and allow it to air‑dry. For stubborn residues, a mild detergent solution followed by thorough rinsing is recommended. Avoid abrasive cleaning tools that could scratch the transparent surface. Store the funnel with the stopper loosely fitted to prevent pressure buildup.

What is the warranty period for this product?

GUOHUIZHANG offers a one‑year limited warranty covering manufacturing defects and material failures. If you encounter any issues within this period, contact our customer service with the purchase details, and we will arrange a replacement or repair as appropriate.
