Separating Funnel QWORK 250ml with 24/29 Joints and PTFE Plug

Description

Product Overview

The QWORK 250ml separating funnel is engineered for laboratory professionals who demand accuracy, durability, and ease of use. Featuring standard 24/29 taper joints, the funnel integrates seamlessly with a wide range of laboratory glassware, ensuring a tight, leak‑free seal when paired with the included PTFE plug. The conical design promotes efficient phase separation, while the clear, high‑quality borosilicate glass provides superior chemical resistance and visual clarity, allowing users to monitor liquid interfaces with confidence. With a compact footprint measuring 13.07 x 5.31 x 4.61 inches and a lightweight construction of just 6.4 ounces, the funnel is easy to handle, store, and transport between workstations. The robust glass body withstands repeated heating and cooling cycles, making it suitable for a variety of experimental conditions, from ambient temperature extractions to reflux operations. Additionally, the PTFE plug is chemically inert, offering long‑term performance without degradation, even when exposed to aggressive solvents or acids.

Usage

Designed for versatility, this separating funnel excels in a broad spectrum of laboratory applications. Whether you are performing liquid‑liquid extractions, phase separations, or solvent washes, the funnel’s precise 250ml capacity provides enough volume for most routine procedures while maintaining a manageable size for bench‑top work. The 24/29 joints accommodate standard ground‑glass stopcocks, allowing seamless integration with existing setups and facilitating quick changes between experiments. The PTFE plug ensures a secure, airtight closure, preventing vapor loss and cross‑contamination during prolonged separations. Users can employ the funnel in organic synthesis labs, analytical chemistry environments, or teaching laboratories, where its clear construction aids in student instruction by visibly demonstrating the separation of immiscible liquids. The funnel is also compatible with rotary evaporators and other auxiliary equipment, expanding its utility across multiple workflows.

FAQ

What types of liquids can be separated with this funnel?

The funnel is suitable for separating immiscible liquids such as organic solvents and aqueous phases, as well as for extracting compounds from mixtures where density differences allow clear phase separation.

Can the PTFE plug be replaced if needed?

Yes, the PTFE plug is designed for easy removal and replacement. Replacement plugs are available from QWORK or compatible third‑party suppliers, ensuring continued performance without compromising the seal.

Is the funnel safe for use with strong acids or bases?

The borosilicate glass construction provides excellent chemical resistance, making the funnel safe for most acids, bases, and organic solvents. However, it is advisable to avoid prolonged exposure to highly corrosive mixtures that exceed the material’s specifications.

How should the funnel be cleaned after use?

Rinse the funnel with an appropriate solvent to remove residues, then wash with warm soapy water. For stubborn deposits, a gentle brush can be used. Rinse thoroughly and allow the funnel to air dry before storage.

What is the recommended storage condition for the funnel?

Store the funnel in a dry, dust‑free environment, preferably in a cabinet designed for glassware. Keep the PTFE plug in place or cover the opening to prevent contamination when not in use.
