Tips and Tricks for the Lab: Column Packing - ChemistryViews

Thus higher mesh values such as "silica gel 230–400" have more holes per unit area and correspondingly smaller particles than "silica gel 60". Typically, 70–230 silica gel is used for gravity columns and 230–400 mesh for flash columns. Alumina is available in types I, II, and III. This refers to the water content of the alumina, with I ...

Mesh Count and You | by Screen.com

Mesh counts above 305, such as 355, 380, and 400, are mainly used for graphic with UV inks. UV inks are extremely thin, and many times are used for high detail on signs, banners, or CDs. Using a higher mesh allows the automatic printers used in UV to regulate the amount of ink passed through the screen.

Micron and Mesh Rating - Welcome to Microna Agriculture

1) Divide either the mesh or micron value into 15,000 to obtain the other value. This is a good approximation over a limited range, say about 45 to 400 mesh. For instance, 15,000/325 mesh = 46 micron. Or 15,000/100 micron= 150 mesh. 2) If you know the distance between wire strands you can use a simple calculation method to find micron.
