They have developed a portable and automatic mini-laboratory in tube form, called MARTINIS, which can measure specific chemical parameters in the soil in situ—that is, where they naturally occur ...

Happily, laboratory tube tumblers automate this for us. The swishing action is handled with rotation. The vials are mounted at angles around a wheel.

A team of researchers has developed a portable and automatic laboratory that can monitor soil chemistry in real time—and without expensive components. The aim is to give us easier access to ...
