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.

Exceptional performance

The single piece cap provides a superior fixed seal, eliminating the risk of leakage or cross-threading.


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

Wide tube design

Ideal for use within homogenisation assays and allows easy access to tissue samples.
