Volumetric Flasks

Volumetric flasks are essential laboratory glassware designed to withstand high tolerances, ensure precise measurement and accurate volume control, and hold a specific fixed volume of liquid at a specific temperature. Sizes available include a 1 ml volumetric flask, a 100 ml volumetric flask, and a 1l volumetric flask. As sizes are measured precisely, they eliminate the need for repetitive volume measurements and increase accuracy. Volumetric flasks are manufactured to the highest quality and materials. Options include autoclavable and chemical-resistant plastics such as a polypropylene volumetric flask. Plastic flasks offer break-resistant properties to ensure safety and are easy to clean within the lab in case of an accident or spillage. Glass and Pyrex volumetric flasks are also an ideal solution to increase accuracy as they are transparent, colored, and coated for handling light-sensitive liquids.

Thomas Scientific also offers a variety of other lab flasks, including erlenmeyer flasks.

What is a stopper in a flask?

A flask stopper is a closure used to seal the flask's opening, preventing the escape of contents and protecting them from contamination. Stoppers can be made from various materials, such as rubber, cork, or glass, depending on the flask type and the experiment's requirements.

Is there a 1 L volumetric flask?

Yes, a 1L (1000 mL) volumetric flask is a standard size commonly used in laboratories. It helps prepare and measure precise volumes of solutions. Like all volumetric flasks, it has a narrow neck with a single calibration mark to indicate the exact volume. The 1 L size is ideal for medium-scale solution preparation in analytical chemistry for making standard solutions and dilutions.

What is a stoppered conical flask used for?

A stoppered conical flask, commonly called an Erlenmeyer flask with a stopper, is used for mixing, storing, and transporting liquids while minimizing the risk of spillage or contamination. The stopper seals the flask, making it ideal for applications that require the contents to remain secure, such as preventing evaporation during storage or transport.

What is the largest volumetric flask?

The largest volumetric flasks commonly available are typically 5 liters (5000 mL) in capacity. These flasks help prepare large volumes of solutions with precise concentrations. Some manufacturers may produce custom or specialized volumetric flasks with capacities beyond 5 liters for industrial or large-scale laboratory applications, but these are less common.
