Tube micrometers have a cylindrical anvil positioned perpendicularly to a spindle and is used to measure the thickness of tubes. Micrometer stops are micrometer heads that are mounted on the table of a manual milling machine, bedways of a lathe, or other machine tool, in place of simple stops. They help the operator to position the table or ...

The earliest molecular drag pump was created by Wolfgang Gaede, who had the idea of the pump in 1905, and spent several years corresponding with Leybold trying to build a practical device. [5] The first prototype device to meet expectations was completed in 1910, achieving a pressure of less than 10 − 6 {\displaystyle 10^{-6}} mbar . [ 6 ]
The term micronization usually refers to the reduction of average particle diameters to the micrometer range, but can also describe further reduction to the nanometer scale. Common applications include the production of active chemical ingredients, foodstuff ingredients, and pharmaceuticals. These chemicals need to be micronized to increase ...
