Graham Condenser 24/40 200mm Jacket – Deschem Borosilicate Glassware

Description

Product Overview

The Deschem Graham Condenser is a precision‑engineered laboratory glassware component designed for demanding chemical synthesis and analytical processes. Constructed from G3.3 borosilicate glass, the condenser offers superior thermal resistance, an annealing point of 560 °C, and a softening point of 820 °C, ensuring dimensional stability even under prolonged heating cycles. The 24 40 joint provides a secure, leak‑free connection to standard laboratory apparatus, while the 200 mm jacket length maximizes surface area for efficient vapor condensation. Linear coefficient of expansion is tightly controlled at 32×10⁻⁷ / °C, reducing stress during temperature fluctuations. The product dimensions of 14.72 × 3.74 × 2.4 inches and a lightweight 11.46 oz design facilitate easy handling and integration into a wide range of setups, from simple reflux rigs to complex distillation columns. Its clear, high‑quality glass allows visual monitoring of fluid flow, aiding in precise process control and troubleshooting. The condenser’s durability, combined with its chemically inert surface, makes it suitable for use with aggressive solvents, acids, and bases without risk of degradation or contamination.

Usage

In laboratory environments, the Graham Condenser excels in applications that require reliable vapor cooling and condensation. It is ideally suited for reflux operations where continuous boiling of reaction mixtures must be maintained without loss of solvent, as well as for fractional and simple distillation where separation of components relies on efficient heat exchange. The 24 40 joint ensures compatibility with standard adapters, condensers, and receiving flasks, allowing seamless assembly within existing glassware networks. Researchers in organic synthesis, pharmaceutical development, and academic teaching labs frequently employ this condenser to achieve high‑purity product isolation while minimizing solvent consumption. Its robust construction also supports use in high‑temperature processes such as azeotropic distillation and steam stripping, where the glass’s low thermal expansion prevents cracking under rapid temperature changes. The clear glass body enables real‑time observation of condensate formation, facilitating adjustments to reflux ratios, heating rates, and cooling water flow. Additionally, the condenser can be integrated into custom apparatuses for gas absorption, moisture removal, or cooling of reaction vapors in pilot‑scale experiments, making it a versatile tool for both routine and specialized laboratory workflows.

FAQ

What types of solvents can I safely use with this condenser?

The Graham Condenser is compatible with a wide range of organic solvents, including ethanol, methanol, acetone, dichloromethane, and toluene, as well as aqueous solutions and acidic or basic media. Its borosilicate composition resists corrosion and does not react with most chemicals, making it suitable for both polar and non‑polar solvents. For highly aggressive reagents, we recommend rinsing the glassware with appropriate neutralizing solutions after use to maintain long‑term performance.

How do I properly clean and maintain the condenser?

After each use, disassemble the condenser and rinse it thoroughly with deionized water to remove residual chemicals. For stubborn residues, soak the glassware in a mild detergent solution or a laboratory‑grade cleaning agent, then scrub gently with a soft brush. Rinse again with distilled water and allow the condenser to air‑dry completely before storage. Avoid rapid temperature changes during cleaning; if the glass is hot, let it cool gradually to prevent thermal shock.

Can this condenser be used for high‑temperature distillation processes?

Yes, the Graham Condenser’s borosilicate glass is rated for an annealing point of 560 °C and a softening point of 820 °C, allowing it to withstand the high temperatures encountered in azeotropic or steam distillation. Its low coefficient of thermal expansion minimizes the risk of cracking during rapid heating or cooling cycles. However, it is essential to monitor temperature gradients and ensure that cooling water flow is consistent to maintain safe operating conditions.

Is the 24 40 joint compatible with other laboratory glassware?

The 24 40 joint conforms to the standard size used in most laboratory glassware, including adapters, flasks, and other condensers. This universal compatibility enables you to integrate the Graham Condenser into existing setups without the need for custom fittings. If a specific connection requires a different joint size, Deschem offers compatible adapters that can be used to bridge the gap.

What warranty or guarantee does Deschem provide?

Deschem offers a one‑year limited warranty covering manufacturing defects and material failures under normal laboratory use. Should any issue arise within the warranty period, contact our technical support team with the product details and purchase information. We will assess the situation and provide a replacement or repair as appropriate, ensuring minimal disruption to your research workflow.
