They are also working to perfect 3D-printed vacuum pumps, which remain a major hurdle to printing an entire compact mass spectrometer.

A vacuum pump in a steel container next to the tube sucks out the air to reduce the internal pressure.

As they circle around, the outer reactors would absorb oxygen from the inner reactors, effectively de-rusting the original metal, without having to use energy-intensive vacuum pumps.

After setting up vacuum pumps in local zoos, the teams were able to sequence DNA from dozens of species.

Persistent supply chain challenges and higher costs have weighed on the maker of compressors, vacuum pumps and industrial tools in recent quarters.
