Slide-bearing assemblies capable of enabling sliding of a load-carrying implement relative to a load-supporting structure, having first and second load-carrying surfaces, respectively, are disclosed. In one embodiment, the slide-bearing assembly includes substantially nonmetallic first and second elongate bearing elements extending in parallel to support the first load-carrying surface of the load-carrying implement slidably upon the load-supporting structure. One of the bearing elements being composed of multiple elongate pieces each shorter in length than a length of the other of the bearing elements. The slide-bearing assembly additionally includes a post that extends from a surface of each of the multiple elongate pieces, which is a surface that is opposed to the second load-carrying surface, each post is sized to fit in a respective recess of the second load-carrying surface. The slide-bearing assembly further includes at least one coating on the first load-carrying surface made of high-performance thermoplastic material(s).

A device and method for scraping and collecting adsorbent from located areas on developed thin layer chromatography plates and extracting substances from collected adsorbent. The above functions can be performed without additional apparatus. The device is constructed of polypropylene to allow for easy use, manufacture and low cost. The shell surrounds a primary filtering and retaining material and a secondary filter. The adsorbent is removed from the thin layer chromatography plate via a scraping edge and collected by aspirating the adsorbent into the device where it becomes embedded in the primary filtering and retaining material. The device can then be separated to allow facile addition of a solvent to elute the sample out of the device free of adsorbent. The scraping process is improved as a result of the polypropylene contact with the plate, the collection process minimizes loss of removed adsorbent, and the elution/filtration allows easy recovery of developed samples. These functions are accomplished within this device and therefore time spent in preparation and cleanup is kept to a minimum. This device is potentially disposable.
