Borosilicate Glass 10000ml / 10L Conical Separatory Funnel with PTFE stopcork

Description

Product Overview

The KimLab 10L borosilicate glass separatory funnel is engineered for high‑performance liquid‑liquid extraction in professional laboratory settings. Constructed from premium borosilicate glass (Boro3.3), the funnel features a heavy‑wall design that resists thermal shock and mechanical impact, extending the lifespan of the instrument even under rigorous use. The conical body, measuring 62 cm in length with a 30 cm diameter, provides ample volume for large‑scale separations while maintaining a compact footprint on the bench.

Key specifications include a 10 L (10 000 ml) capacity, a ground‑glass top opening compatible with standard glass stoppers (#40/38 or #50/42), and a PTFE stopcork that delivers a chemically inert, leak‑free seal. The PTFE material resists a wide range of solvents, acids, and bases, ensuring that the funnel can handle aggressive reagents without degradation. The precision‑machined ground glass joint guarantees a smooth, secure fit, minimizing the risk of accidental disconnection during critical operations.

Usage

This separatory funnel excels in applications that demand reliable phase separation, such as organic synthesis, pharmaceutical development, environmental testing, and quality‑control laboratories. Its large volume capacity makes it ideal for scaling up reactions, performing bulk extractions, or processing substantial sample quantities in a single run, reducing the need for multiple smaller funnels and streamlining workflow.

Designed for both academic and industrial environments, the funnel can be used with standard laboratory stands, clamps, and rotary evaporators. The PTFE stopcork allows for precise control of venting and pressure release, essential when working with volatile solvents or reactions that generate gases. The heavy‑wall glass construction also provides excellent visibility of the liquid interface, enabling operators to monitor separation progress with confidence.

FAQ

What types of solvents can the PTFE stopcork handle?

The PTFE stopcork is compatible with most organic solvents, acids, and bases, including dichloromethane, chloroform, methanol, ethanol, hydrochloric acid, and sodium hydroxide solutions. It maintains its sealing properties even under aggressive chemical conditions.

Can the funnel be used for heated separations?

Yes. The borosilicate glass construction tolerates temperatures up to 350 °C, allowing the funnel to be employed in heated separations or reflux setups without risk of deformation or breakage.

Is the funnel compatible with standard laboratory stands?

Absolutely. The funnel’s 30 cm diameter and 62 cm length are designed to fit common laboratory clamps and stands, making integration into existing workstations straightforward.

How do I ensure a proper seal with the glass stopper?

Insert the appropriate glass stopper (#40/38 or #50/42) into the ground‑glass joint, then gently rotate to achieve a snug fit. The PTFE stopcork should then be placed into the stopper opening, providing a tight, leak‑free seal.

What warranty does KimLab offer?
