Thermo Scientific™ Matrix™ ScrewTop Tri-coded Tubes
Description
Securely store precious samples at low temperatures, including vapor phase Liquid Nitrogen with Thermo Scientific™ Matrix™ 0.64 mL and 1.1 mL ScrewTop Tubes. Tubes are molded from medical grade resins and feature a permanent, high contrast 2D,1D linear and human readable barcode. These tubes can be ordered to come in racks (barcoded or non-barcoded) or may be purchased in bulk. The tri-coded tubes can be purchased sterile or non-sterile. We also offer tubes with white patch only if your work does not require the 1D linear and human readable code. The 2D screwtop tubes meet a range of manual and automated long term storage needs; barcoded racks make it easy to track the rack as well. Use in combination with Thermo Scientific barcode readers, arrayers and capping equipment.
Dependable Sample Protection
- Tubes are constructed of virgin class VI medical grade polypropylene
- ScrewTop caps feature a soft silicone gasket that conforms to mating surfaces to ensure sample preservation
- Racks are constructed of sturdy ABS to protect tubes in case of drops
- ScrewTop tubes are compatible with storage down to -196°C
Secure Tracking
- Permanent, unique 2D tube barcode is laser-etched on bottom of each tube
- Racks feature linear barcode, human readable ID and 2D barcode for ultimate sample tracking
- 2D barcode on tubes allow you to scan and decode tubes all at once without removing them from the rack, and allows data to be associated with each tube
- Tube and rack are compatible with Thermo Scientific™ VisionMate™ readers
Superior Storage Format
- ANSI-format latch racks maximize storage space and are compatible with multichannel manual pipettes or automated liquid handling equipment
- Several capping / decapping options available to manipulate a single tube, 8 tubes, or 96 tubes at once

Frequently Asked Questions (FAQs)
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.
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.
