Which Thermo Scientific 2D barcoded storage tubes should I use for my application?

Answer

Please view the following information regarding the usage of Thermo Scientific 2D barcoded storage tubes:
Tube Type; Typical Storage Temperature; Application(s); Special Feature(s)
Sepraseal; -20 degrees C; Compound storage; Can easily be removed for sample access
Presplit Sepraseal; -20 degrees C; Compound storage; Up to 200 piercings
Duraseal; -20 degrees; Compound storage; Safe seal for multiple piercings
Matrix ScrewTop; -80 degrees C; Blood components, DNA, Bacteria; With the correct torque, there is very little evaporation at -80 C, disposable pipette tips can be used
Nunc Screwcap; -176 degrees C; Mammalian cells; Minimal height, tubes can be removed with cryo gloves

Product FAQ

Can I store the Thermo Scientific 2D barcoded storage tubes in standard 10x10 cryoboxes?

Answer

Yes, the Thermo Scientific 2D barcoded storage tubes can be stored in standard cryoboxes. However, we do not carry 2D barcode readers capable of reading a full box of 2D barcodes in this storage format.

Product FAQ

Why do you recommend Nunc Cryobank vials for liquid nitrogen storage and the Matrix ScrewTop storage tubes for storage at higher temperatures?

Answer

We recommend using Nunc Cryobank vials for liquid nitrogen storage as these vials are designed for use at ultra-low temperatures. They come without a lid so that they can be easily picked from the rack at ultra-low temperatures using a tube selection or pen tool.
On the other hand, we recommend Matrix ScrewTop storage tubes for use at higher temperatures (-80 degrees C and above). They work well for both manual and automated picking.

Product FAQ

Can the barcodes on the Thermo Scientific 2D barcoded storage tubes be damaged by chemicals or by exposure to extreme temperatures?

Answer

The Thermo Scientific 2D barcoded storage tubes have been subjected in-house to consecutive liquid nitrogen freeze-thaws followed by submersion in boiling water. These tests did not cause any damage to the 2D barcode.
The 2D barcodes are made of the same material as the storage tubes and are resistant to standard lab chemicals.
The 2D barcode has a built-in ECC200 error barcode correction, which ensures that a damaged barcode is still readable as long as less than 25% of the barcode is missing.

What kind of storage tube should I use to prevent the breakdown of RNA in tissue during cold storage?

Product FAQ

How do you prevent 2D barcode duplication during manufacturing and ensure quality control of the Thermo Scientific 2D barcoded storage tubes?

Answer

The 2D barcode laser etching software includes algorithms that prevent the barcode generator from ever counting backwards, subsequently preventing the re-etching of any previously generated barcode. To verify the above procedure, several quality control checks are performed on the 2D barcodes including:
- Checking for light transmission through the barcode as light transmission will reduce readability
- Inspecting the barcode under magnification
- Reading the barcode on a full rack 2D barcode reader
- Checking the barcode against a database of previously etched 2D barcodes
As the above quality control steps are completed, defective storage tubes are discarded, replaced, and re-checked, ensuring that the 2D barcodes are 100% readable and have not been previously used. This quality control process is the reason why we cannot guarantee sequential 2D barcode printing within a single rack of 2D barcoded products.
