The silicone ring is a support for 5.0 mL round-bottom tubes. A round-bottom tube does not stand upright on its own. The ring cradles the round bottom and holds the tube vertical. This lets you place the tube neatly in a box or rack.
The rings are supplied in packs of 500. They are made of silicone and withstand low temperature. You use them in cryo storage with Thermo Scientific systems. This keeps round-bottom tubes orderly and upright.
