What types of sample collection tubes are available?

Arctic White offers sterile, low-protein-binding cryovials in 0.5 mL, 1.0 mL, 1.5 mL, and 2.0 mL formats. Options include external thread and internal thread caps, with compatibility for -80°C and liquid nitrogen (-196°C) cryogenic storage.

Can sample collection tubes be stored at liquid nitrogen temperatures?

Yes, polypropylene sample collection tubes and cryovials maintain structural integrity at -196°C (liquid nitrogen temperatures). They are designed for long-term cryogenic storage without cracking, warping, or compromising seal integrity.

Are sample tubes compatible with automated capping systems?

Yes, Arctic White's sample collection tubes are designed for compatibility with automated capper/decapper systems including the XL9, XL20, XL100, and XL200. Standard tube dimensions ensure reliable cap placement and removal in automated workflows.

Do sample tubes support barcode labeling?

Yes, sample collection tubes are compatible with 2D and 1D barcode labels. The tube surface accommodates labels that adhere securely even at -196°C. Arctic White's XL LabelPro system automatically applies barcoded labels with precision positioning.

What is the difference between external and internal thread caps?

External thread caps screw onto threads on the outside of the tube, keeping the interior surface smooth and reducing contamination risk. Internal thread caps screw into threads inside the tube opening, creating a more compact seal but with threads contacting the sample area.

Sample Collection Tubes

Arctic White sample collection and storage tubes provide secure, contamination-free containment for biological samples, compounds, and clinical specimens—from ambient handling to long-term cryogenic storage at –196°C in liquid nitrogen. The portfolio includes internal-thread and external-thread CryoVials with O-ring, washer, and lip seal configurations for vapor-tight cryogenic performance, plus ST500/ST501 screw-cap tubes for general-purpose and clinical sample storage.

All tubes are manufactured from medical-grade polypropylene or polycarbonate, certified DNase-, RNase-, pyrogen-, and human-DNA-free. Tamper-evident transport tube options meet secure chain-of-custody requirements. Complementary accessories include CryoVial workstations, storage canes, colored cap inserts for visual sample identification, and racked storage boxes for organized biobank and compound repository management.
