Our popular gridded boxes allow you to tell exactly where your samples are in a cardboard box without having to label the box. Grid lines are on the inside and outside of the tube area and are visible with the tubes inserted. Position can be logged in your inventory system. Our latest expansion of this line introduces hinged colored versions of our grid box and a price that saves you up to 40% or more from our high price competitors. In addition, the new hinged boxes have rigid 81 or 100-place plastic dividers.
