Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.
The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.

The CO2 incubator ICOmed is the perfect solution: Thanks to the battery-buffered ControlCOCKPIT, the operating display, logging and CO2control remain fully functional even when there is a power failure. All parameters are logged in accordance with the FDA and, when individually adjusted ranges for CO2, O2, temperature and humidity are exceeded, notifications can be sent to a mobile phone in addition to an alarm. With its rounded corners, the interior is easy to clean and can be sterilised for 60 minutes at 180 °C (including all sensors). The active humidity control offers optimal protection for cell and tissue cultures. It minimizes evaporation in the interior and ensures short recovery times.
