The well position is also standardized, but only for 96- , 384-, and 1536-well plates. These are generally well followed by manufacturers: Well Positions [16] [17] 96-well plates have a 9 mm well-to-well spacing, 384-wells a 4.5 mm spacing, and 1536-wells a 2.25 mm spacing. A notable characteristic is that the well array is symmetrical when the ...
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
Here, I redesigned the 96-well plate figure working from an overlay of a 96-well plate manufacturer technical drawing, and the official SLAS/ANSI 96-well plate size standards.

White space around the chart is filled with map information and the legend, scales, and tables of airport and airspace information. Terrain is color-coded for its elevation and major roads, cities, and bodies of water are shown for visual reference, as well as other identifiable structures (e.g., stadiums and water towers). However, most of the ...

I designed the figure from an overlay of a 384-well plate manufacturer technical drawing. Designed in Inkscape. The Inkscape "Tiled clone" tool where the percentage row/column shift was calculated by (well spacing/well width-1.00)*100 (in this case, 12.5%), was essential to producing regularly spaced wells.
A spot plate, also called a reaction plate, color test plate, [1] or spotting tile (British English), is a laboratory tool made either from ceramics or plastics. [2] Each plate consists of many cavity-like depressions in which only small amount of reactants can be added at a time. [ 3 ]
The SI unit for permeability is the square metre (m 2).A practical unit for permeability is the darcy (d), or more commonly the millidarcy (md) (1 d ≈ 10 −12 m 2). The name honors the French Engineer Henry Darcy who first described the flow of water through sand filters for potable water supply.
