Abstract

Abstract A centrifuge rotor having a base plate with a plurality of support posts mounted thereon. Each support post receives and supports the radially inner end of a sample container support element formed of a wound composite material. The outer end-turn of the support element receives and supports a sample container. The side walls of the support element are arranged to lie generally radially of the central vertical axis of the rotor.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 109 words
A centrifuge rotor comprising: a first plate; a post having a first end and a second, other, end and having a predetermined exterior configuration, one end of the post being supported from the first plate; a sample container support element mounted to the post, the support element being formed of a composite material and having generally radially extending side walls connected to each other through a radially inner and a radially outer curved end-turn portion, the radially inner end-turn portion being configured to correspond to the exterior configuration of the post; and a sample container secured on the interior of the radially outer end-turn portion of the support element.
Claim 2
Dependent Claim 109 words
A centrifuge rotor comprising: a first plate; a post having a first end and a second, other, end and having a predetermined exterior configuration, one end of the post being supported from the first plate; a sample container support element mounted to the post, the support element being formed of a composite material and having generally radially extending side walls connected to each other through a radially inner and a radially outer curved end-turn portion, the radially inner end-turn portion being configured to correspond to the exterior configuration of the post; and a sample container secured on the interior of the radially outer end-turn portion of the support element.
Claim 3
Dependent Claim 25 words
