Rethinking the test tube rack.

A space-saving solution for keeping centrifuge balance tubes organized, accessible, and right where you need them.

Your balance tubes have a place…

Balance tubes are essential to the centrifuge workflow, but they don't always have a dedicated place to live. Drawers, countertops, and crowded supply areas can make finding the right tube an unnecessary part of the process.

The Balance Tube Keeper gives them a dedicated home, right at the centrifuge.

…it just might not be a very good one.

A reimagined test tube rack.
