The Rotary evaporator is widely used in the laboratory for solvent evaporation and concentration, but occasional leakage may adversely affect the experimental results and instrument performance. This article will introduce the common reasons for the leakage of the Rotary evaporator, provide the leakage treatment methods, and how to prevent leakage measures, in order to help laboratory personnel to ensure that the experiment is safe and ensure the working efficiency of the Rotary evaporator.
Reason for leakage
Aging or damage of seals: aging, damage or incorrect installation of Rotary evaporator seals may lead to leakage.
Overfilling: Overfilling the sample container may cause leakage, as gas or vapor may be generated during the evaporation process of the sample.
Temperature and pressure changes: Changes in temperature and pressure may cause the sealing material to expand or contract, leading to leakage.
Improper operation: Improper use or operation may also lead to leakage, such as excessive rotational speed or improper installation of sample containers.
Leakage handling
Emergency measures: In case of leakage, stop using the Rotary evaporator immediately and ventilate the surrounding area. At the same time, wear appropriate protective gloves and personal protective equipment such as glasses to prevent solvent from coming into contact with skin or eyes.
Leakage source localization: Determine the specific location and cause of the leakage, check whether the sealing components are intact, check whether the sample container is installed correctly, and whether there are other damages or faults.
Sealing treatment: Replace damaged seals and ensure correct installation of seals to ensure good sealing effect.
Cleaning and maintenance: regularly clean the Rotary evaporator, remove the accumulated solvent residue, and check whether all parts of the instrument work normally.
Leakage prevention
Regular maintenance: regularly check and maintain the Rotary evaporator to ensure the integrity and normal working condition of the seals.
Reasonable operation: use the Rotary evaporator correctly according to the operation manual and instructions, avoid overfilling the sample container, and pay attention to the temperature and pressure changes during operation.
Periodic detection: regular leakage detection, using gas detector or leakage detector and other methods to detect whether there is potential leakage problem of Rotary evaporator.
Training and awareness: train laboratory personnel to improve their awareness of Rotary evaporator leakage prevention and treatment, and strengthen their safety awareness and operation specifications.
