The Carry/Incubation Tube was designed to hold one Assayer Ampoule after sample inoculation and allow for safe, convenient incubation (ie: shirt breast or jacket pocket).

It is made of clear, durable polycarbonate with a black rubber cap and a bottom surrounded by a black rubber bumper.

The clear bottom enables the user to view the ampoule axially (as per the instructions) for the color change without having to remove the ampoule each time it is viewed.

The Carry/Incubation Tube is reusable.
