  1. To chemists, rotary evaporation is like washing hands with a surgeon or breathing air to the rest of us. The technology has been established in many laboratories around the world, so it is particularly exciting to show it. Do you know all the applications related to this technology? Do you know how to configure the instrument to suit your needs, so as to improve evaporation efficiency? Please read on for more information.
    The way the rotary evaporator is set up depends largely on the characteristics of the sample.
    Sample characteristics such as boiling point, heat sensitivity, corrosivity, and acidity may affect the settings of the rotary evaporation system. Different types of condensers, heating baths, vapor tube, vacuum pumps, coolers, and programmable methods can be used in combination to assist in processing challenging samples to improve evaporation efficiency.

    There are also various special attachments to help solve the challenges that arise during the evaporation process.
    For example, if you encounter foam, you might consider using a foam sensor. If you are dealing with solid samples, you may consider using a vapor tube with a glass frit. If you want to process samples with unknown characteristics, you can try to use an instrument with automatic distillation. If you have a sample that is sensitive to sunlight, you can use a special amber glass to protect the sample. If extraction is required, a Soxhlet extractor attachment can be added to the rotary evaporator.


    Finally, the configuration of rotary evaporation will be affected by factors that you think are critical to a particular process.
    For example, if you want to maximize evaporation efficiency as much as possible, you might benefit from large instruments with large flasks, large heating tanks, large vapor tube, auxiliary condensers, and more robust coolers. If you want to comply with strict regulations, you can consider using the rotary evaporation system that comes with IQ / OQ services. If you want to maximize safety, you can invest in accessories such as splash guards and shields. If you want a more environmentally friendly operation, you can consider using swimming balls, covers, and tools with ECO mode. And, if you want to minimize hands-on time, look for automatic options such as foam sensors and automatic method programming.

    Of course, depending on the batch size and operating frequency, other types of rotary evaporation systems can also be considered, such as parallel evaporation or industrial evaporation.
