FAQS CONSUMABLES FOR SAMPLE STORAGE- 2D MICROTUBES

For ultra-low temperature storage (-80 °C and below), LVL-Technologies recommends the use of 2D microtubes with external screw caps.
This design significantly reduces the contact area between the sample and the inner surface of the cap, thereby minimizing the risks of cross-contamination, substance transfer, or unwanted physicochemical interactions.
These risks are particularly increased with internal screw cap tubes during agitation or centrifugation steps, where liquid samples may rise and remain in contact with the internal thread.
A detailed comparative study addressing these phenomena is available in the LVL-Technologies Technical Note, provided to all users upon request in paper or electronic format.

Yes. 2D microtubes Safe® from LVL-Technologies are manufactured from medical-grade polypropylene (USP Class VI), selected for its high chemical inertness, very low extractables, and compatibility with demanding biological applications.
These materials are ideally suited for long-term storage of sensitive biological samples and minimize interactions with DNA, RNA, proteins, or other analytes, even under prolonged ultra-low temperature conditions.
Quality and compliance assessment tests have been conducted to meet the standards of research laboratories and biobanks. Detailed results are available in the LVL Technologies Technical Note, upon request.

2D microtubes Safe® from LVL-Technologies are designed for storage in standard SBS racks or cryoboxes.
LVL-Technologies also offers customized metallic boxes, compatible with the main refrigerator, freezer, and liquid nitrogen tank models available on the market.
Individual 2D DataMatrix identification ensures fast, reliable, and secure sample management, facilitating inventory control and storage optimization.
For advanced workflows, the use of automated reading systems and traceability software is strongly recommended.
In this context, the Safe® range by LVL-Technologies includes a new generation of readers capable of reading all types of 2D microtubes, either individually or in SBS racks and/or 9×9 or 10×10 cryoboxes.

Yes. Safe® range 2D microtubes are guaranteed RNase free and DNase free.
They are manufactured under controlled and sterile conditions and subjected to strict quality procedures, ensuring compatibility with molecular biology, genomics, and high-value sample storage applications.

Significant space savings can be achieved by switching from internal screw cap tubes to 2D microtubes with external screw caps.
Thanks to the cap design, where the thread fits around the outer upper part of the tube, this configuration allows for height optimization and increased storage density.
In addition, switching from 9×9 or 10×10 cryoboxes to an SBS format provides further space optimization while enabling future automation of the biobank.
Finally, integrating the Hi-Thèque software allows storage optimization while ensuring full and secure sample traceability even remotely.
Our teams are available to support you in all initiatives aimed at sustainably optimizing your storage capacity.

Safe® range 2D microtubes are designed, manufactured, and quality-controlled in Europe, within fully controlled industrial environments meeting the requirements of scientific and biotechnological applications.
This European manufacturing ensures consistent quality, full batch traceability, and strict compliance with international standards.
By maintaining full control over its production and supply chain, LVL-Technologies ensures a reliable and sustainable product availability, even for long-term biobank projects or high-volume requirements.
This approach minimizes supply chain risks and guarantees continuity for research activities and the storage of critical biological samples.
