StonyLab Dewar Condenser Finger Borosilicate 200mm Jacket 24/40 Joint

Description

Product Overview

The StonyLab Dewar Condenser is engineered as a premium cold‑finger condenser designed for demanding laboratory environments where reliability, durability, and performance are essential. Constructed from high‑quality borosilicate glass, the unit can withstand temperatures up to 200 °C, providing a robust barrier against thermal shock and chemical corrosion. Its 200 mm jacket length maximizes surface area for efficient heat exchange, while the 24/40 lower drip tip facilitates precise condensate control during distillation, reflux, and other cooling processes. The 40 mm inner diameter (I.D.) offers ample flow capacity, reducing back‑pressure and ensuring smooth liquid handling. The condenser’s heavy‑duty design incorporates a reusable, leak‑free joint system that minimizes waste and operational costs, aligning with sustainable laboratory practices. The transparent glass construction allows easy visual monitoring of condensate formation, enabling rapid adjustments and improved experimental outcomes.

Usage

Designed for a wide range of scientific applications, the Dewar Condenser excels in organic synthesis, analytical chemistry, and educational laboratory settings. It is particularly well‑suited for processes that require dry‑ice cooling, such as low‑temperature distillations, sublimations, and vacuum‑assisted condensations. The condenser can be integrated into standard laboratory glassware assemblies, connecting seamlessly to round‑bottom flasks, reaction vessels, and receiving flasks via the 24/40 joint. Its versatile geometry accommodates both vertical and horizontal orientations, allowing users to adapt the setup to space constraints and specific experimental protocols. The unit’s durability makes it ideal for repeated cycles of heating, cooling, and cleaning, ensuring consistent performance over extended periods. Whether employed in research laboratories, quality‑control facilities, or teaching labs, the Dewar Condenser delivers reliable temperature control and condensate collection, supporting accurate data collection and reproducible results.

FAQ

What temperature range can the Dewar Condenser safely operate within?

The condenser is made from borosilicate glass that tolerates temperatures up to 200 °C, making it suitable for both low‑temperature dry‑ice cooling and moderate heating applications without risk of glass deformation or breakage.

Can the condenser be used with solvents other than water?

Yes, the chemical resistance of borosilicate glass allows the condenser to handle a wide variety of organic solvents, acids, and bases commonly used in laboratory procedures, provided that proper safety protocols are followed.

How do I clean and maintain the Dewar Condenser?

After each use, rinse the glass thoroughly with appropriate solvents to remove residues, then dry with filtered air or a lint‑free cloth. For stubborn deposits, a mild alkaline solution can be employed, followed by a final rinse with distilled water. Regular inspection of the joint and drip tip ensures a leak‑free connection.

Is the 24/40 joint compatible with standard laboratory glassware?

The 24/40 joint conforms to common laboratory standards, allowing seamless connection to standard round‑bottom flasks, condensers, and receiving vessels. Adapters are available if a different joint size is required for specific setups.

What warranty or after‑sales service does StonyLab provide?

StonyLab offers a one‑year limited warranty covering manufacturing defects, along with responsive technical support. If the product arrives damaged or exhibits performance issues, the support team will arrange repair, replacement, or refund in accordance with the warranty terms.
