Made of high impact polystyrene
This microcentrifuge tube storage box with a polyurethane foam insert is ideal for holding up to 64 tubes from 0.5 ml to 2 ml. It should be used within a temperature range of -90 °C to 80 °C. A transparent cover allows you to see the contents of the box, and is keyed to the base in order to prevent misalignment. To improve your inventory control, you can write with a marker pen on the cover surface which is pre-printed with a series of squares (numbered from 1 to 64). You can also save space by stacking these boxes in freezers, refrigerators and on lab counters.
