Rectangular cells are used for most UV/VIS routine analysis. By far the most common type of cell, they have two windows clear and conform to international standard dimension. The 10mm pathlength size should fit most instruments that use rectangular cells. Available pathlengths are from 1mm to 100mm. Check with your instrument manual to see if you need an adaptor for longer pathlength cells.
Standard rectangular cells are the most commonly cells used. The have two polished windows and a full interior width used in most instruments.

The semi-micro cells have the same exterior dimension as the standard cells but the interior walls parallel to the lightpath are thickened . This makes the interior sample chamber width 4mm thus reducing the sample requirements by 60%.

Micro cells have the same exterior dimension as the standard cells but the walls parallel to the light path are thickened even more than the semi-micro. This makes the interior sample chamber width 2mm thus reducing the sample requirements by 80%.

Sub-micro cells optimize the use of very small volumes (10 to 160 microliters) by using a narrow sample chamber, raising the sample chamber directly into the center of the light path and masking with black quartz entirely around the sample chamber.
