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.

Key Features
  • 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
That is an excellent summary of the classic Erlenmeyer flask design. Its iconic conical shape was specifically engineered by Emil Erlenmeyer in 1860 to solve several common laboratory problems:
  • 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.
