Glass Conical Flask 250ml | Measuring Flask, Molecular Flask, Erlenmeyer Flask, Chemistry Flask

Product Information

Borosil® Narrow Mouth Conical Erlenmeyer Flasks with Interchangeable Glass Stopper comes Uniform wall thickness distribution makes these flasks ideal for heating. Cell culture flasks are often supplied with specialized cell-adherent treated surfaces and vented filters. Though our products are essentially scientific in nature, they are commonly used in a variety of everyday processes, from food to education. The cosmetics industry relies on accurate pH measurements for quality control purposes, to help ensure consistency between batches of a product, and that the properties of the product are within the specified guidelines. International standards are reviewed every five years, with this standard reviewed and confirmed in 2020.

Add a few drops of indicator close indicator A substance that has different colours, depending upon the pH of the solution it is in. The titre close titre Volume of one reactant needed to react completely with the other reactant in a titration. The titre will depend upon the volume of liquid in the conical flask, and the concentrations of the acid and alkali used. 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. We have become experts in scientific operations, improving performance with sophisticated solutions and providing guidance on best practices.

They are supplied with precise, one-mark graduations and a stopper, and are designated as Class A or Class B depending on their accuracy. He wrote that he first displayed the new flask at a pharmaceutical conference in Heidelberg in 1857, and that he had arranged for its commercial production and sale by local glassware manufacturers. Borosilicate Glass Erlenmeyer Flasks are designed to give the best combination of thermal shock resistance, physical strength, and resistance to chemical attack, Narrow Mouth with Screw Cap.

Our electrodes are suitable for laboratory settings such as the measurement of biological samples, pharmaceuticals, rapidly-changing temperatures, flat surfaces, viscous and non-aqueous samples, drinking water, wastewater, and much more. 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. Wide neck conical flask - The wider neck design of these laboratory flasks allow for denser liquids to be combined by stirring with a rod. VWR has a range of new services designed to streamline your operations, help you make cost savings and manage your laboratory effectively.

The final two attributes of Erlenmeyer flasks make them especially appropriate for recrystallization. I have completed my post-graduate study in medical microbiology at the central department of microbiology, TU, Nepal.

Due to the flask’s tiny opening, it can also be used to filter various substances with filter paper. Erlenmeyer flasks used in cell culture are sterilized and may feature vented closures to enhance gas exchange during incubation and shaking. Manufactured and supplied to our valued clients with full discretion and confidentiality, our biotechnology electrode products are put through rigorous testing and are assured for quality performance and durability. Our electrochemical electrodes for pH, oxygen, carbon dioxide and redox potential measurement are suitable for bioprocess control and can be made either directly in the bioreactor or in the laboratory.

The oxygen transfer rate in Erlenmeyer flasks depends on the agitation speed, the liquid volume, and the shake-flask design. 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. This required practical involves using appropriate apparatus to make and record a range of measurements accurately, including volume close volume The volume of a three-dimensional shape is a measure of the amount of space or capacity it occupies, eg an average can of fizzy drink has a volume of 330 ml. The tops of the flasks are open and can accommodate a variety of closures, including screw caps and stoppers.

We’re proud to unveil an exciting transformation for our electrodes, offering a fresh aesthetic that maintains our commitment to quality and dependability. Our industrial electrode range is manufactured for accuracy and backed by years of experience for industrial settings such as semiconductor production, hydrofluoric acids from waste fluids and other acidic substances, and general manufacturing processes that require accurate and reliable results. The conical flask is manufactured under two standards namely ASTM (American Society for Testing and Materials) and ISO (International Organization for Standardization) . The conical flasks can be used for various purposes like mixing, heating, and storing chemicals or reagents. We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development.Used widely in laboratory settings, conical flasks are also used in schools for chemistry lessons and even in bars for cocktail displays. 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.
