A method and apparatus for the accurate monitoring of a granule during compression testing is provided and enables the study of breakage mechanisms that cause particle failure during compression. The method involves compressing a granule or particle with the apparatus and the apparatus is a spring device that combines a spring in parallel with the granule or particle and a spring in series with the granule or particle. Under failure conditions, sudden deformation of the granule or particle results in fast relaxation of the granule or particle during breakage and allows very careful granule breakage. Measuring or recording devices coupled to the apparatus provide for the detailed study of breakage conditions at the moment of failure and lend incite into the compression strength characteristics of the granule or particle.

The invention relates to a device for the alignment and location of a sample (7), such as pills or tablets, for carrying out a further method step, such as a hardness test, with the aid of two opposing jaws (2, 3, 21), which may be moved relative to each other, the movable compression jaw (2) of which displaces the sample (7) along a guide track on to the fixed counter-jaw (3, 21), in order to begin the further method step with the sample (7). The forward movement of the movable compressing jaw (2), along with the sample (7) towards the fixed counter-jaw (3, 21) is continuously interrupted, the compressing jaw (2) being drawn backwards and driven forwards, such that the sample oscillates about the rest position thereof and then the compressing jaw (2) continues the movement towards the counter-jaw (3, 21) until the sample (7) reaches said counter-jaw (21). Furthermore, the fixed jaw (3, 21) and/or the guide track (6, 34) may be set in vibration during the forward motion of the movable jaw (2) towards the fixed counter-jaw (3, 21).

Apparatus, methods, and systems for high throughput useful sampling of seed, wherein viability is selectively maintained, are disclosed. Seed from one generation in a plant advancement experiment is individually sampled by removal and collection of tissue from the seed using a hand-held and manually operated tool having one or more cutting edges. The tissue is then processed to derive one or more biochemical, genetic, or phenotypic characteristic of the seed before a decision is made whether to utilize that seed further in a plant advancement experiment or other plant research and development. In some embodiments of the method, the sampling is controlled to remove a useful amount of tissue for analytical purposes without significant effect on viability potential of the sampled seed. In some embodiments, the sampling is controlled to deter contamination of the sample. In some embodiments, the seed is held in pre-determined orientation to facilitate efficient and accurate sampling.
