An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the as collected condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples.

A filter assembly for a solenoid-actuated valve includes a filter band adapted to be disposed about a valve body of the solenoid-actuated valve. The filter band has a first end and a second end. The filter assembly also includes a locking mechanism to lock the first end and the second end together. The locking mechanism includes one of the first end and the second end having a slot extending therein and at least one aperture extending in communication with the slot and another one of the first end and the second end having at least one post to pass through the at least one aperture such that the first end and the second end lock together in a closed position.

A filter band assembly for a solenoid-actuated valve includes a filter band adapted to be disposed about a valve body of the solenoid-actuated valve. The filter band has a first end at one end and a second end at another end. The filter band assembly also includes a separate bracket affixed to one of the first end and the second end and adapted to support the one of the first end and the second end on the valve body to allow the first end and the second end to be joined together in a closed position.

A filter includes a plurality of first through holes which are periodically formed. At least one of the plurality of first through holes is divided by a plurality of second through holes that are smaller than the first through holes. With such a configuration, the cell aggregate having the desired size can be easily sampled.

A filter assembly including a filter screen (27) comprising a band (27) of porous material extending between two axially aligned opposing ends (38, 38) and defining a cylindrical periphery (29), wherein the ends (38, 38) are each secured to a dynamic tensioning mechanism (46) that permits the ends (38, 38) to move bi-directionally relative to one another about the periphery (29) of the filter screen (27).

For a lubricant press (1), a follower piston (13) is proposed that can be inserted into a cartridge (4) and is matched to a closing wall (6) of a cartridge holder (3), such that the follower piston (13) in the used-up cartridge (4) lies against the closing wall (6) in a planar manner.

Modular sectorised filtering element consisting of a flat modular filter element whose surface has at least two concentric strips, the stacking of which forms a filter surface. This module allows the sectorised filtration of the fluid passing through it, with the possibility of the same filter surface also having parts dedicated simultaneously to filtration, washing, different degrees of filtration, etc. It is composed of an outer perimeter strip (1) with a zig-zag groove (4), an intermediate perimeter strip (2) with holes (6), which have radial walls (7), and concentric separation walls (8) of a stackable shape, and an inner perimeter strip (3) with a configuration similar to the outer strip (1).
