Abstract: A blending device (2) for blending a sample held in a sealable open mouthed sample bag comprises a bag receiving portion (6). The blending device (2) also includes a kneading arrangement (20) for acting on a wall of a sample bag (8) disposed in the bag receiving portion (6) so as to blend a sample contained in the bag (8). A bag manipulation arrangement (13) or a bag support (28) may also be provided.

Abstract: A centrifuge rotor including a sample carrier (1) enclosing within an outer housing (7,8) and being rotatable about a principal axis of rotation of the rotor, the sample carrier (1) having a peripheral zone for holding sample tubes (6) in an orientation parallel to the said axis when at rest and the sample carrier being capable of deflecting to enable sample tubes (6) to swing out under the effect of centrifugal force. The swinging out of the tubes (6) is constrained and controlled by the arrangement of the sample carrier (1) and contact between the tubes (6) and outer housing (7,8).
