Separating Funnel QWORK 1000ml Heavy Wall with 24/29 PTFE Stopcock

Description

Product Overview

The QWORK 1000ml heavy‑wall conical separating funnel is engineered for laboratory environments where reliability and precision are paramount. Constructed from high‑quality borosilicate glass, the funnel offers exceptional chemical resistance and thermal stability, allowing it to withstand a wide range of solvents, acids, and temperature fluctuations without compromising structural integrity. Its conical shape promotes efficient phase separation, while the heavy‑wall design adds durability and reduces the risk of breakage during routine handling or accidental impacts.

Designed with a standard 24/29 taper clamp, the funnel seamlessly connects to a variety of laboratory glassware, including flasks, beakers, and distillation apparatuses. The integrated PTFE stopcock provides a leak‑free seal and smooth operation, enabling precise control over fluid transfer and minimizing loss of valuable reagents. The stopcock’s polytetrafluoroethylene (PTFE) construction ensures compatibility with aggressive chemicals and offers a long service life, even under continuous use.

Key specifications include a 1000ml capacity, a compact footprint of 0.46 x 0.46 x 5.66 inches, and a weight of 3.81 pounds, making it easy to handle while still providing the robustness required for heavy‑wall applications. The funnel is supplied with a dedicated laboratory distillation support rack, which offers a stable platform for the funnel during titration, extraction, and distillation processes, reducing the likelihood of spills and enhancing overall safety.

Beyond its core functionality, the QWORK separating funnel is thoughtfully designed with user convenience in mind. The clear glass construction allows for easy visual monitoring of liquid layers, facilitating rapid assessment of separation progress. The included support rack features adjustable clamps that accommodate various instrument sizes, ensuring a secure fit regardless of the experimental setup. Together, these features make the funnel a versatile addition to any chemistry, biochemistry, or environmental testing laboratory.

Usage

In titration experiments, the QWORK separating funnel provides a reliable means of separating reaction mixtures after the titrant has been added. Its precise PTFE stopcock allows the operator to control the release of the lower phase, ensuring that the endpoint is accurately observed without cross‑contamination. The heavy‑wall construction also helps maintain the integrity of the funnel when subjected to vigorous stirring or shaking, common practices in titration protocols.

For extraction procedures, the funnel excels at isolating organic and aqueous phases. The conical design encourages rapid coalescence of the denser phase at the bottom, while the PTFE stopcock enables smooth drainage of the desired layer. Researchers performing liquid‑liquid extractions can rely on the funnel’s chemical resistance to handle a broad spectrum of solvents, from non‑polar hydrocarbons to polar alcohols, without degradation.

During distillation, the accompanying support rack stabilizes the funnel, allowing it to serve as a collection vessel for condensed vapors. The 24/29 fitting ensures a tight connection to the distillation column, preventing vapor leaks and maintaining system efficiency. Whether the application involves simple water distillation or more complex organic syntheses, the QWORK funnel delivers consistent performance and ease of cleaning, thanks to its smooth glass interior and removable stopcock.

Why Choose Us

QWORK is a recognized brand in laboratory equipment, known for rigorous quality control and adherence to international standards. Each separating funnel undergoes a multi‑stage inspection process, including visual inspection for glass imperfections, dimensional verification of the 24/29 taper, and functional testing of the PTFE stopcock for smooth operation and leak resistance. This commitment to quality ensures that every unit delivered meets the expectations of demanding scientific professionals.

Our heavy‑wall design is not merely a marketing term; it reflects a deliberate engineering choice to enhance durability while maintaining a manageable weight. The additional glass thickness provides resistance to thermal shock, allowing the funnel to be safely heated or cooled without cracking. This robustness translates into lower replacement costs and reduced downtime for laboratories that rely on continuous operation.

FAQ

What types of chemicals can the funnel safely handle?

The funnel is made from borosilicate glass, which is resistant to most acids, bases, and organic solvents. It can safely be used with common laboratory reagents such as hydrochloric acid, sodium hydroxide, ethanol, acetone, and many others. However, extremely aggressive chemicals like hydrofluoric acid should be avoided, as they can etch glass.

How do I clean and maintain the PTFE stopcock?

After each use, rinse the stopcock with a suitable solvent (e.g., distilled water followed by isopropyl alcohol) to remove residues. For stubborn deposits, soak the stopcock in a mild detergent solution, then scrub gently with a soft brush. Rinse thoroughly and dry before re‑assembly to ensure optimal performance and longevity.

Can the funnel be used for high‑temperature applications?

Yes, the heavy‑wall borosilicate glass is designed to tolerate temperature changes up to approximately 300 °C. This makes the funnel suitable for heating processes such as reflux or steam distillation, provided that the temperature does not exceed the glass’s rated limit and that appropriate safety precautions are observed.

Is the support rack adjustable for different instrument sizes?

The support rack features adjustable clamps that can accommodate a range of flask and beaker diameters, from small laboratory flasks to larger distillation columns. This flexibility ensures a secure fit for various experimental setups, enhancing stability and reducing the risk of accidental spills.

What is the warranty period for this product?

QWORK offers a one‑year limited warranty covering manufacturing defects in materials and workmanship. Should any issue arise within this period, customers can contact our support team for a replacement or repair, subject to the terms outlined in the warranty documentation.
