OPTIVISION® vial technology creates highly visible red bubble edges for exact placement between the reading lines and optimal vision in bright and low light.
But it’s not just about the color, the tilted angle of the vial gives a direct line of sight to the bubble with no distortions and this, together with the high contrast ratio between the bubble and vial liquid makes for quicker readings and more precise results. These vials are UV resistant, always maintaining their original color and visibility.
OPTIVISION® vials are a Kapro patented innovation.
