NOTE: You may search by any of the criteria listed below. As an example, if you would like to just see NEW microscopes, click on the down arrow to the right of -Select- on the New or Reconditioned line and highlight NEW. When you click submit only NEW records will be displayed. Completion of additional fields to NEW or RECONDITIONED adds to the search requirements. You could select NEW and then type a Manufacturer in the text field box and then you would click submit to see a list of only NEW from that Manufacturer. 
Searching By Model, By Control Number will work the same way. The more criteria you select the more precise will be the search. If you do not select any criteria then you will see all of the records in the microscopes database.
