Innovative manufacturing

Our tubes are manufactured by a highly specialised 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.

The durable 2D barcodes 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.


All tubes are manufactured from medical grade virgin polypropylene & certified DNase, RNase and Endotoxin (Pyrogen) free.

Code recovery

The AlteTube 2D DataMatrix barcodes adhere to the ECC200 standard. Reed-Solomon error correction codes in the DataMatrix barcode reconstructs and verifies data for improved accuracy.
