Solvent Safety Caps Supply
Protect your health
Harmful of health  
The sealed solvent safety cap ensures that no solvent vapor escapes, and the mobile phase mixing ratio is stable, protecting your health.
It is easy for mobile phase harmful gases escape from unsealed container, causes potential hazards in the lab, and long-term inhalation of person can cause unexplained health problems.
Clean Mobile Phase
The safety valve prevents dust particles in the air and prevents the mobile phase from being trapped contaminated. Analysis results remain unaltered and reproducible. 

Mobile phase contaminated

Dust, dirt, and impurities from the ambient air can contaminate the mobile phase and have a destructive effect on the chromatogram. 

Stable Mixtures
Sealed system can make solvent mixtures remain stable. Individual components can no longer evaporate- the mixing ratio remains constant.

Unstable mixtures
Mobile phase contaminated
Air in the

For unsealed container, different evaporation rates of solvents in the mobile phase will cause pH value change, which will affect the selectivity, Capacity factor, peak shape, resolution and reproducibility of HPLC/UHPLC analysis.

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.

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

When the pump extracts the mobile phase, negative pressure is generated in the container. The safety valve ensures safe pressure balance of the solvent bottle during operation.

If the capillary tube is not locked tightly and may slip out of the container making air enters the HPLC system, and shutdown is inevitable.
