Innovative manufacturing in a clean room environment

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.

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

Permanent barcodes & Human Readable Number

The 2D barcode, 1D barcode and Human Readable Number are laser etched on the black polypropylene base and side strip of the one piece AlteTubeTM. The durable 2D barcodes are designed to survive in the harshest of lab environments. Every barcode meets our exacting standards for readability.

Tubes come with 2D barcodes only if preferred.

External thread screw caps

Increased working sample volume per tube compared to internal thread tubes in most storage conditions. Compatible with the arktic® automated sample store from SPT Labtech.

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.

Clever cap design

Works to provide a deforming compression seal from a thread which secures very quickly and is fully engaged after a maximum rotation of 180°. The benefit is seen within an automated workflow and storage.
