Z366-250-A50R by Hermle is a 3-position round-bottom insert (2/pk) for the Hermle Z366-250 swing-out rotor, fitting 50 ml round-bottom tubes in the Z366 and Z366-K universal centrifuges. The round-bottom seat stabilizes vessels that would tilt in a conical insert (Z366-250-A50). Two inserts per pack cover both rotor bucket positions.
