Description
Product Overview
The Chemglass CG-4025-04 series represents a benchmark in laboratory glassware engineering, delivering a vacuum hydrolysis tube that combines precision dimensions with superior material performance. Constructed from high‑grade borosilicate glass, the tube offers exceptional resistance to thermal shock, chemical attack, and mechanical stress, ensuring longevity even under demanding laboratory conditions. Its 20 mL internal volume provides ample space for a variety of drying and reaction processes, while the 19 mm outer diameter and 100 mm length create a compact footprint that fits seamlessly into standard lab racks, condensers, and drying apparatuses.
Beyond its core specifications, the tube incorporates a smooth, seamless interior surface that minimizes sample adhesion and facilitates easy cleaning. The uniform wall thickness contributes to consistent vacuum integrity, reducing the risk of leaks during prolonged operations. The design also includes a tapered neck that allows for secure sealing with standard ground‑glass joints, enhancing safety when handling volatile or moisture‑sensitive compounds. This combination of form and function makes the CG‑4025‑04 an indispensable tool for chemists, biochemists, and material scientists seeking reliable drying and hydrolysis capabilities.
The product’s manufacturing process adheres to ISO‑9001 quality management standards, guaranteeing that each tube meets stringent dimensional tolerances and visual clarity criteria. Chemglass Life Sciences, the manufacturer, has a long‑standing reputation for delivering laboratory glassware that meets the rigorous demands of research institutions, pharmaceutical companies, and industrial laboratories worldwide. The CG‑4025‑04 vacuum hydrolysis tube is no exception, offering a blend of durability, precision, and ease of use that supports reproducible experimental outcomes.
Usage
Designed for versatility, this vacuum hydrolysis tube excels in a range of laboratory applications. It is particularly well‑suited for drying solvents, reagents, and solid samples under reduced pressure, where its robust construction prevents breakage during vacuum cycles. Researchers frequently employ the tube in azeotropic distillation setups, where the combination of a 20 mL capacity and a 19 mm OD enables efficient removal of water or other low‑boiling impurities while maintaining a stable reaction environment.
In addition to drying, the tube serves as an ideal vessel for hydrolysis reactions that require controlled exposure to moisture or acidic conditions. Its glass composition tolerates a wide pH range, allowing chemists to perform acid‑catalyzed hydrolysis of esters, amides, and other functional groups without concern for container degradation. The tube’s length also facilitates the insertion of magnetic stir bars, ensuring homogeneous mixing throughout the reaction mixture.
The CG‑4025‑04 is compatible with standard laboratory equipment such as rotary evaporators, vacuum pumps, and desiccators, making it a seamless addition to existing workflows. Its dimensions align with common rack sizes, enabling efficient storage and organization in busy lab environments. Whether used in academic research labs, quality‑control facilities, or industrial process development, the tube provides a reliable platform for moisture‑sensitive operations.
