Protect your health  
Affect your health  
The sealed XIMAI solvent safety cap ensures that no solvent vapor escapes, and the mobile phase mixing ratio is stable, protect your health.

Unsealed container, it can cause the mobile phase to 

evaporate andrelease harmful gases, posing a safety 

hazard in the laboratory. The harmful gases generated 

can linger in the laboratory for a long time and be 

inhaled by the human body through the nose or mouth,

which can affect the physical health of you and colleagues.


Clean Mobile Phase
The safety valve prevents dust particles in the air and prevents the mobile phase from being trappedcontaminated.Analysis resultsremain unaltered and reproducible.For clean separation without interfering or overlapping peaks in thechromatogram.

Mobile phase contaminated

Dust, dirt, and impurities from the ambient air 

can contaminate the mobile phase and have 

a destructive effect on thechromatogram. 

Pollution can generate overlapping peaks, 

making it more difficult to identify the substance 

being sought.

Stable Mixtures
Due to the closed system, your solvent mixtures remain stable. Individual components can no longer evaporate- the mixing ratio remains constant.

Unstable mixtures
Mobile phase contaminated
Air in the

Unsealed container, different evaporation rates

 of different solvents in the mobile phase will 

cause changes in the mobile phase pH value, 

which will affect the selectivity, Capacity factor

(retention coefficient), peak shape,resolution 

and reproducibility of HPLC/UHPLC analysis, 

especially UHPLC.

Analysis without Air Bubbles
Capillaries and tubes remain tightly screwed in and cannot slip out of the solvent. Interruptions due to air pockets are avoided.

Air in the HPLC
Mobile phase contaminated
Air in the
Safe Pressure Equalisation

The capillary tube is not locked tightly and may 

slip out of the container. The consequence is 

that the inhaled air enters the high-performance 

liquid chromatography system, and shutdown is

inevitable.

When the pump extracts the mobile phase,negative pressure is generated in the container. The XIMAI 

safety valve ensures safe pressure balance of the 

solvent bottle during operation.
