Allihn Condenser 24/40 200mm Glass Lab Heat Exchanger by Deschem

Description

Product Overview

The Deschem 24/40 200mm Allihn condenser is a precision‑engineered laboratory glassware component designed for efficient heat exchange in a variety of chemical processes. Constructed from G3.3 borosilicate glass, the unit exhibits a linear coefficient of expansion of 32×10⁻⁷/℃, an annealing point of 560 °C, and a softening point of 820 °C, ensuring dimensional stability and resistance to thermal shock even under rigorous reflux conditions. The condenser features a classic Allihn design with a spherical bulb and a series of graduated cooling fins that maximize surface area for rapid condensation of vapors. Its compact dimensions—14.5 × 3.54 × 2.36 inches and a lightweight 7.83 oz—make it easy to integrate into standard laboratory setups, while the 24/40 joint size provides compatibility with a wide range of adapters and flasks. The product is certified by Deschem Science Supply, a reputable manufacturer known for delivering high‑quality scientific glassware that meets stringent industry standards. With a best‑seller rank of #9 in Lab Allihn Condensers, this model has earned a reputation for reliability and performance among researchers and educators alike.

Usage

Designed for use in academic, industrial, and research laboratories, the Allihn condenser excels in applications such as reflux, distillation, and gas‑washing operations. Its efficient cooling fins allow rapid condensation of volatile compounds, making it ideal for prolonged reflux runs where temperature control is critical. The glass construction permits visual monitoring of the condensation process, enabling users to observe the formation of droplets and adjust heating parameters in real time. The condenser is compatible with standard heating mantles, oil baths, and water‑circulating chillers, providing flexibility for both low‑temperature and high‑temperature processes. Whether you are synthesizing organic compounds, purifying solvents, or conducting analytical experiments, the 24/40 joint size ensures a secure, leak‑free connection to round‑bottom flasks, condensate receivers, and other apparatus. The device’s durability also makes it suitable for educational settings, where frequent handling by students demands robust glassware that can withstand accidental impacts and rapid temperature changes.

FAQ

What type of cooling fluid should I use with this condenser?

Cold tap water or a chilled water bath is recommended for most reflux applications. For temperature‑sensitive processes, you may use an ice‑water mixture or a refrigerated glycol solution, ensuring the flow rate is sufficient to maintain consistent cooling across the fins.

Can this condenser be used with organic solvents?

Yes, the G3.3 borosilicate glass is chemically resistant to a wide range of organic solvents, including ethanol, methanol, acetone, and many hydrocarbons. Always verify compatibility with specific reagents, especially strong acids or bases, and follow safety guidelines.

Is the 24/40 joint compatible with standard round‑bottom flasks?

The 24/40 joint is a common size that fits securely onto most 250 mL to 1 L round‑bottom flasks equipped with a matching ground‑glass joint. Using appropriate ground‑glass adapters can extend compatibility to larger or smaller vessels.

How do I clean and maintain the condenser?

After each use, rinse the condenser thoroughly with distilled water to remove residual chemicals. For stubborn residues, a mild detergent solution followed by a thorough rinse is effective. Allow the glass to air‑dry or gently wipe with a lint‑free cloth. Avoid rapid temperature changes to prevent thermal shock.

What warranty does Deschem provide for this product?

Deschem offers a one‑year limited warranty covering manufacturing defects. If the condenser arrives damaged or develops a defect under normal use, contact Deschem customer service for a replacement or repair.
