temperature control

Accurate temperature control is crucial when using the Shanghai Yetuo rotary evaporator. Excessive temperature may lead to solvent evaporation and sample loss, while low temperature can affect evaporation efficiency. Therefore, the temperature setting should be adjusted according to experimental requirements before operation, and the temperature control system should be regularly checked and calibrated to ensure temperature stability and accuracy.

Speed regulation

The rotational speed of a rotary evaporator has a significant impact on the evaporation efficiency and sample concentration. Excessive speed may lead to sputtering and sample loss, while excessively low speed can prolong the experimental time. Therefore, in operation, it is necessary to adjust the appropriate rotation speed according to experimental requirements and avoid frequent speed changes to maintain a stable and uniform evaporation process.

Sealing performance

The sealing of the rotary evaporator is crucial to prevent gas or steam leakage. Checking and maintaining the integrity of the seals is a crucial step to ensure good sealing performance. When replacing seals, suitable materials and models should be selected, and installation should be strictly carried out according to the operating instructions to ensure good sealing performance.

Sample overflow

Sample overflow is a common issue during the evaporation process. The quantity of samples and the size of the container should be reasonably matched to avoid waste and cleaning difficulties caused by sample overflow. In addition, regular cleaning and maintenance of the evaporator to remove accumulated solvent residues are also important measures to prevent sample spillage.
