Transparent cover allows the user to see the contents of the box, and is keyed to the base to prevent misalignment. Printed with a series of squares (numbered from 1 to 25, 1 to 42, 1 to 81, or 1 to 100), surface accepts writing with markers, facilitating inventory control. Can be used from –196 to +121 °C.

A unique colour coding system uses coloured plastic grids to separate the cover from the base on the 25-, 42- and 81-place boxes. Those made to accept 100 tubes have a coloured base instead of a grid.
