Product Overview
The 50 ml Schlenk reaction flask from CS Labglass is engineered for precision and reliability in demanding laboratory environments. Its pear‑shaped design maximizes liquid handling efficiency while the heavy‑wall borosilicate construction provides exceptional thermal resistance and chemical durability. The flask features a 24/40 outer joint, a standard size that easily accommodates a variety of accessories such as addition funnels, reflux condensers, and magnetic stirring assemblies. Integrated with a high‑quality glass stopcock, the flask allows secure connection to vacuum lines or inert gas sources, facilitating air‑sensitive reactions with minimal risk of contamination. The transparent borosilicate material ensures clear visual monitoring of reaction progress, while the robust wall thickness protects against breakage during routine handling and cleaning. Dimensions of 2.64 × 4.13 × 5.91 inches and a weight of 8.11 oz make the flask compact yet sturdy, suitable for both benchtop and glove‑box applications. Manufactured by CS Labglass, a reputable supplier known for stringent quality control, each flask undergoes rigorous testing for leak integrity, dimensional accuracy, and optical clarity before shipment.
In addition to its functional attributes, the flask’s design reflects thoughtful ergonomics. The smooth, rounded neck provides a comfortable grip for easy manipulation, and the glass stopcock is engineered with a low‑friction valve that ensures smooth operation even after repeated cycles of opening and closing. The 24/40 joint is compatible with a wide range of standard laboratory glassware, enabling seamless integration into existing setups without the need for adapters. This versatility reduces inventory complexity and streamlines experimental workflows. The flask’s high chemical resistance makes it suitable for use with a broad spectrum of solvents, acids, bases, and reactive gases, further expanding its applicability across organic synthesis, inorganic chemistry, and materials science research.
Technical specifications include a capacity of 50 ml, a 24/40 outer joint, and a glass stopcock made from chemically resistant borosilicate. The product dimensions are 2.64 × 4.13 × 5.91 inches, and it weighs 8.11 oz, offering a balance between portability and durability. The flask is supplied as a single unit, ready for immediate integration into laboratory protocols. Its compliance with industry standards ensures compatibility with safety equipment such as fume hoods and glove boxes, supporting safe handling of volatile or toxic reagents. The product is listed under ASIN B0F99P7KQV and holds a Best Sellers Rank of #22 in Lab Reaction Kettle Flasks, reflecting its popularity among researchers seeking reliable Schlenk apparatus.
Usage
The 50 ml Schlenk flask excels in a variety of experimental contexts, particularly those requiring stringent control of atmospheric exposure. Researchers conducting air‑sensitive reactions, such as organometallic syntheses, can rely on the flask’s airtight stopcock and compatible joint to maintain an inert environment throughout the reaction sequence. The flask is also ideal for moisture‑sensitive processes, where the ability to purge the system with dry inert gas is essential to prevent hydrolysis or unwanted side reactions.
In practical laboratory setups, the flask can be paired with an addition funnel to introduce reagents under a controlled atmosphere, while a reflux condenser attached to the 24/40 joint enables temperature‑controlled reflux operations. Magnetic stirring bars can be inserted through the joint, allowing efficient mixing without compromising the sealed environment. The flask’s design also supports low‑temperature applications, as the borosilicate glass tolerates cryogenic conditions without cracking, making it suitable for reactions conducted at sub‑ambient temperatures.
Beyond synthetic chemistry, the flask serves analytical purposes such as gas collection, distillation, and drying of volatile compounds. Its clear walls facilitate visual observation of phase changes, color development, and precipitation, aiding in real‑time decision making. The flask’s compact size makes it convenient for use in glove boxes, where space is limited, while its robust construction ensures safety during handling of reactive gases or liquids. Whether employed in academic research, industrial R&D, or quality control laboratories, the flask provides a reliable platform for reproducible, high‑fidelity experiments.

FAQ
What types of solvents can be used with this Schlenk flask?
The flask is made from borosilicate glass, which is resistant to most organic solvents, acids, and bases. It can safely handle solvents such as THF, diethyl ether, dichloromethane, acetonitrile, as well as aqueous solutions, provided they are not highly corrosive to glass.
Can the flask be used for cryogenic reactions?
Yes, the heavy‑wall borosilicate construction tolerates low temperatures and can be used in cryogenic applications down to –196 °C (liquid nitrogen) without cracking, making it suitable for low‑temperature syntheses.
Is the glass stopcock compatible with standard vacuum lines?
The glass stopcock is designed to fit standard laboratory vacuum fittings and can be connected directly to vacuum pumps or inert gas manifolds using appropriate adapters, ensuring a leak‑free seal.
How should the flask be cleaned after use?
We recommend rinsing the flask with a suitable solvent to remove residues, followed by washing with a mild detergent solution. Rinse thoroughly with deionized water and dry with a lint‑free cloth or allow to air‑dry. For stubborn deposits, a gentle soak in a compatible cleaning solution may be used.
What warranty does CS Labglass provide for this product?
CS Labglass offers a one‑year limited warranty covering manufacturing defects. If the flask arrives damaged or exhibits a defect during normal use, contact our support team for a replacement or repair.
