Volumetric Flask 250mL – Laboratory Measuring Flask with Stopper

The Volumetric Flask 250mL is precision laboratory glassware designed for preparing solutions to a defined 250mL volume. It is commonly used where accurate volume preparation is important, including analytical chemistry, reagent preparation, dilution and quantitative laboratory procedures. The flask typically features a bulb-shaped body, flat base, long narrow neck and a single calibration mark corresponding to its nominal 250mL capacity. The narrow neck allows the liquid meniscus to be carefully adjusted to the calibration line.
