Small universal stand for 50 ml and 15 ml centrifuge tubes (such as Falcon tubes) as well as 0.5 ml, 1.5 ml and 2 ml microlitre tubes (such as Eppendorf tubes).
The footprint is kept as small as possible so that the stand does not take up so much space in the laminar flow cabinet without running the risk of constantly tipping over.
For the centrifuge tubes, two viewing windows are recessed in order to be able to see even a low liquid level.

Do not forget that PLA is not UV stable and would be grilled during self-sterilization in the bench.
