Product Information

VWR takes care of sourcing, production, testing, and documentation of your chemicals. We manufacture what you need.

Erlenmeyer’s flask is utilised for the preparation of concentration solutions and chemical analysis. It is primarily employed in the titration procedure and is hence also known as a “Titration Flask.” The variety of laboratory flasks includes boiling flasks, cell culture flasks, distilling flasks, Erlenmeyer flasks, filtering flasks, freeze drying flasks, Kjeldahl flasks, recovery flasks, and volumetric flasks. Manufactured from a variety of materials, flasks are typically made of glass or plastic resins such as polystyrene, polypropylene, polycarbonate, polymethylpentene, or PTFE. Depending on their application, flasks can be sealed with various closures, including air-tight screw caps, vent caps, and stoppers made of ground glass, glass, plastic, or rubber. Narrow Mouth - It is used to support the filter funnels while experimentation. The solution can be mixed simply by swirling the flask. Whether you need equipment and supplies for your laboratory applications, biopharma product support or products ensuring carefully controlled environments at your facility—Avantor can help.Environmental analysis such as water treatment methods relies on substantive results from quality electrochemical measurement of our natural environment. Whether it’s our own drinking water or the natural habitats of flora and fauna, from oceans to rivers and our built municipal sewage or aquariums, controlling the quality of water is essential. Variety of size: Conical flask is available in various sizes that allow a wide range of applications. Erlenmeyer flasks are constructed to be far more durable than typical laboratory flasks. They contain 25% more glass than standard wall flasks and hence have a longer shelf life. Colour - available in a choice of clear or amber, the most popular of these is clear, although amber colour is ideal for light sensitive substances.

Stop adding the acid when the end-point close end-point In a titration, the point at which the indicator first permanently changes colour. is reached (when the indicator first permanently changes colour). Note the final volume reading. There are a couple of international standards relating to conical flasks, so we've chosen one to break down and explain to keep you informed and up to date with quality requirements for laboratory equipment.So much has changed during this unprecedented time, except your ability to count on Avantor. We continue to set science in motion to create a better world by providing you with the right solutions to keep moving forward.

Cleanrooms or other controlled environments used for research or manufacturing need specialized products. Avantor can help maintain cleanroom standards with protective apparel and environmental monitoring equipment. We’ve built our reputation on consistent, comprehensive mastery of day-to-day operations, allowing lab, clinical, and production environments to focus their high-value resources on core scientific priorities.

Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections - they may also appear in recommendations and other places. Avantor Services provides a wide range of specialized services and digital solutions to help you solve complex challenges.Test tubes have their place in the laboratory and are very useful. However, when a chemical reaction is expected to be larger than the capacity of a test tube, or two chemicals need to be mixed thoroughly, a conical flask is the ideal piece of equipment for the job. The final two attributes of Erlenmeyer flasks make them especially appropriate for recrystallization. The sample to be purified is heated to a boil, and sufficient solvent is added for complete dissolution. The receiving flask is filled with a small amount of solvent, and heated to a boil. The hot solution is filtered through a fluted filter paper into the receiving flask. Hot vapors from the boiling solvent keep the filter funnel warm, avoiding the premature crystallization.
