CENTRIFUGE BOTTLE CLOSURE AND ASSEMBLY THEREOF.

摘要

A closure (12) for attachment to a centrifuge bottle (14). The closure (12) comprises an end wall (20) and a sidewall (22) extending from the end wall (20). The sidewall (20) comprises a first terminal end (26), a second terminal end (32), a first transition surface (36), and a second transition surface (38). The first terminal end (26) has a first outer peripheral boundary (28) at a first radial distance (R1 ) from an axial centerline (24). The second terminal end (32) has a second outer peripheral boundary (34) at a second radial distance (R2) from the axial centerline (24). The second radial distance (R2) is less than the first radial distance (R1 ). The first transition surface (36) extends between the first outer peripheral boundary (28) and the second transition surface (38). The second transition surface (38) extends between the first transition surface (36) and the second outer peripheral boundary (34).
