Colour your world with a wide variety of economical stackable storage boxes for your snap or screw cap 5mL tubes. These storage boxes are designed to be used at temperatures between -90 and +80°C. A 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, the surface accepts writing with markers, facilitating inventory control. Two corners of the cover and base are cut to prevent misalignment. A unique colour-coding system uses coloured plastic grids to separate the cover from the base.
