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

Product Information

Size - often a range of sizes are required to cover all requirements, with each type of flask classified by their capacity in millilitres. Main factor for out-of-phase operation is the viscosity of the culture medium, but also the vessel diameter, low filling levels and/or a high number of baffles.

These will help you to lay a foundation for the topic and hopefully allow class time with your teacher to be more about understanding opposed to learning. Sentek are able to provide sensors that are designed with these applications in mind, such as our non-aqueous pH electrode.

To impede illicit drug manufacturers, the state of Texas previously restricted the sale of Erlenmeyer flasks to those who have the requisite permits. Add a few drops of indicator close indicator A substance that has different colours, depending upon the pH of the solution it is in. Their slanted sides and narrow necks allow the contents to be mixed by swirling without the risk of spills, which is useful for titrations and for boiling liquids. 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.

Mostly made in clear glass, some versions are made in an amber colour to protect light-sensitive chemicals. We continue to set science in motion to create a better world by providing you with the right solutions to keep moving forward. This quality standard outlines the requirements for the manufacture of boiling flasks with conical ground joints for laboratory use. Pyrex™ Borosilicate Glass Vacuum Filter Flask with Side Arm features heavy walls to provide increased mechanical strength while 'studded' base minimises surface abrasion.This is the volume of acid that exactly reacts with the sodium hydroxide solution of unknown concentration. Various industrial applications require robust electrochemical testing with the aid of durable electrodes from Sentek.
