Linen Testers

The Linen "tester" is a convenient folding type magnifying glass not just for inspecting linen and cloth, but for inspecting any kind of flat sample prior to examination in either a light or scanning electron microscope. Microscopists find these "linen testers" to be the ideal kind of tool to use for identifying important areas that have to be cut out of a relatively flat kind of sample for further analysis and inspection. Plastic frames are not for everyone since they lack the higher precision of the (somewhat more expensive) metal frame equivalents. Available either in the PEAK® or SPI Supplies® brands.
