Ziath has reported on how its 2ml CryzoTraq 2-ECT storage tube maintains high sample integrity by minimizing the chance of cross-contamination as its externally threaded design is designed to eliminate the possibility of samples encountering the screw thread.

Cryogenic storage is widely used in laboratories to preserve valuable samples in vapor phase liquid nitrogen, a method that requires unique products that can tolerate low temperatures without compromising the samples. CryzoTraq 2-ECT tubes are made from non-cytotoxic and non-mutagenic plastic resins and are certified Human DNA, DNase/RNase/Pyrogen and ATP/PCR Inhibitor free, sterile to SAL 10-6 and compliant with IATA PI 650 for safe transport by air. While CryzoTraq 2-ECT tubes are designed to safely store samples down to -195C they may also be used at general cold-storage temperatures.

Each CryzoTraq 2-ECT tube carries a unique 2D Datamatrix code inserted in the bottom, sequential and corresponding to the “Code 128” printed on the tube body. They are designed for storing cells, blood, serum, and other biological fluids. Their unique design includes an innovative bi-injected cap where plastic and silicon parts are melted in a single body which ensures that there is no leaking or contamination and gives a tight grip when screwed shut. The cap design allows the use of suitable automatic capper/decapper systems, such as the IntelliX-cap from Azenta Life Sciences.

CryzoTraq 2-ECT tubes have screw-style closures that ensure their externally threaded caps stay on despite temperature and air pressure changes that occur during sample thawing. Skirted bottoms on CryzoTraq 2-ECT tubes allow them to stand up unaided on your laboratory workbench.

Ziath specializes in developing instrumentation and software specific for sample management using 2D Data Matrix bar-coded tubes. These products are used in academic, biotech, and pharmaceutical organizations. Part of the Consumables and Instruments division of Azenta Life Sciences, the company is well-placed to support customers worldwide.
