The tubes are manufactured by a highly specialized and automated process, known as dual injection. This process creates a powerful molecular bond between the clear tube and the black base. The result is the single piece AlteTube.
Permanent 2D barcode
The 2D DataMatrix barcode is laser etched on the black base of the tube. Every barcode meets our exacting standards for readability and are designed to survive in the harshest of lab environments.
Internal thread screw caps
The TPE and polypropylene dual injected cap provides a superior fixed seal. The single piece cap eliminates the risk of leakage or cross threading.
