Meet your tracking and packaging requirements for solid or liquid sample storage with Thermo Scientific™ Nunc™ Low-Profile 5.0mL Externally-Threaded Universal Tubes. A robust solution for solid or liquid sample storage, tubes feature 2D barcodes, graduations, a white patch for labeling, and a wide-mouth design for easy addition and extraction of sample material. The externally threaded design minimizes contamination risk in manual handling procedures. The tubes and rack are rated for storage down to vapor phase liquid nitrogen temperatures.

Flexible Tube Design

  • Wide mouth provides easy access using forceps for adding approximately (3) 1mm sections of tissue, plant material or other solid sample for storage
  • Overall tube height of less than 50mm and U-bottom shape allows convenient access with standard length pipette tips when used for liquid storage
  • Available with or without a 2D barcode
  • Include printed graduations and white writable surface for manual sample identification
  • Can be purchased in universal style latch rack or in bulk to meet your sample handling requirements

Cap Design

  • The cap features automation-friendly screw top that is compatible with Nunc capping and decapping equipment
  • The tube with the externally threaded cap is designed for cryostorage down to the vapor phase of liquid nitrogen

Secure Tracking

  • Permanently bonded, unique 2D barcode is laser-etched on base of tube to securely identify and track samples
  • Now available in a barcoded rack to allow tracking of the rack in addition to individual tubes
  • Thermo Scientific 2D barcode reader instantly decodes each tube's barcode, transferring tube information into your application or database
  • Tubes include white writable space for sample information in addition to, or instead of, using 2D barcodes

Stringent Quality Control

  • 2D barcodes are scanned after manufacturing to ensure readability
  • Barcodes are checked against database of previously assigned codes to prevent duplicates
  • Tubes are leak-tested to ensure sample integrity and security

Frequently asked questions (FAQs)

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

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.

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

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.
