Vacuum & Ionization
The Vacuum and Ionization process removes contaminants such as loose dirt carton lint aerosols and fine glass particles. 

V & I Cleaning Process: 
1) Compressed air passes through a condensate separator and coalescing filter to remove aerosols and fine dust particles. 
2) Next the air passes through an absorbent filter to remove gases. 
3) A vacuum draws the particulate-laden atmosphere out of the container. 
4) Individually cleaned closures are immediately placed on the container.

Benefits of V & I: 
• Is extremely cost-effective. 
• Saves time! No need to waste valuable time rewashing bottles. 
• Provides a clean final appearance. 
• You will not find any dust particles floating in your samples. 
• Seals cleanliness into each individual bottle. Since each container is individually cleaned they will not collect dust flies and other debris while stored in your lab. 
• Odor-free and tasteless. The air inside the bottle will not interfere with your product in any way.
