Particle Organizer Location & Number

This photo is an optical micrograph at a magnification of 1000x showing one particle storage post and its identifying address number.
The Particle Organizer is useful for archiving important particles that have been collected for study. It has a 10 x 10 array of posts on which to deposit the particles. Each post has next to it a unique identifying number (0-99) so that you never have to worry about whether you have the right particle under the microscope. The posts are 25 microns tall, and 20 x 20 microns square. The organizer is a silicon chip 5 mm x 5 mm. The surface is a 0.25 micron layer of silicon dioxide. The chip can be put in the electron microscope, or optical microscope, or many other scientific analytical instruments.
In normal use, the chip is handled with hand-held tweezers. The particles are placed on the storage pedestals using microtweezers.
