This is an adapter that lets you insert a 0.5 mL tube into a space meant for a 1.5 mL tube. The tab is exactly the size of a closed 1.5 mL tube, and it has a chamfer that your fingernail fits into so that it is easy to remove the adapter from a machine. The bottom of the tube is exposed so that you can push it out if it gets stuck inside.
The usual way to centrifuge a 0.5 mL tube is to nest it inside a 1.5 tube, but I often had catastrophic failures when centrifuging samples for long periods at high speeds; the 0.5 tube would twist inside the larger tube, its rim would get wedged, and then it (and the tube's cap) would rip off entirely. This adapter prevents this by giving more support to the 0.5 tube's rim. I have successfully tested this in PLA, spinning full tubes at 15,000 RPM (around 21,100 RCF) for 10 minutes at a time without damage to the tubes or delamination of the adapters.
You should test your own tubes and prints to make sure that they can withstand centrifugation at the forces, periods, and temperatures you need, before you risk samples.
