A glass bottle roll-on is a dispensing valve assembly designed for viscous liquids, featuring a spherical glass or ceramic ball seated in a metal housing. The core mechanism relies on gravity and mechanical action to control flow without pumps.
Application
- Pharmaceuticals: Used with automated filling lines for serums and tinctures.
- Cosmetics: Paired with high-speed capping machines for fragrances and oils.
- Laboratories: Integrated into precision dosing systems for reagents.
Precautions
- Environment: Operate within 5°C–40°C; avoid humidity exceeding 60%.
- Pressure: Max internal pressure limit is 1.5 bar.
- Maintenance: Inspect seals monthly; replace if viscosity exceeds 5000 cP.
