Conical (Erlenmeyer) Flask, Jointed, Borosilicate 3.3

An Erlenmeyer flask, also known as a conical flask or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. Erlenmeyer Flasks with Sockets are designed for modular laboratory setups where leak-free, airtight connections are required.

• Material: High-quality Borosilicate 3.3 glass, offering superior thermal shock resistance and chemical durability.
• Compliance: Manufactured in accordance with ISO 4797 (for jointed flasks) and IS 1381.
• Design: Conical body with a flat base, featuring a precision ground-glass socket for secure assembly with condensers, addition funnels, or distillation heads.
• Standard Joints: Commonly equipped with 14/23, 19/26, or 24/29 socket sizes to match standard laboratory glassware

• Swirling without Spilling: The wide base and tapered sides allow you to mix liquids vigorously by hand without the contents splashing out, which is why they are the standard choice for titrations.
• Reduced Evaporation: The narrow neck acts as a "choke point," slowing down the loss of solvent compared to a wide-mouth beaker.
• Condensation & Reflux: When heating liquids, the sloped sides help vapors condense and trickle back down into the solution, keeping the volume more stable.
• Easy Labelling: As you mentioned, the matte marking spot (sometimes called the "frosted" or "ceramic" patch) is specifically designed to be written on with a lead pencil or lab marker, making it easy to track samples during an experiment.
