MULTI-SAMPLE CONDITIONING SYSTEM

摘要

A multi-sample conditioning system may include a sample chamber for each sample or a sample chamber holding one or more samples. Multiple samples enable replication for statistical analysis and individual sample chambers enable individual nutrient flow profiles for each sample. A mechanical imbalance may be created when a sample chamber is removed or when samples of different stiffness are conditioned together. The mechanical imbalance may result in an undesired alteration of the desired conditioning profile and increase the variation in the conditioning profile applied to each sample. An asymmetric-loading support assembly provides a low friction support to reduce the undesired alteration of the desired conditioning profile applied to the samples and reduce unwanted reaction loads on the conditioning drive mechanisms. The asymmetric-loading support assembly preferably includes a flexure as the low-friction, high-stiffness support. Other examples that can provide low-friction, high-stiffness support include air bearings, magnetic bearings, and hydraulic bearings.
