Thermo Scientific™ Matrix™ 500μL ScrewTop Tubes
Description
Store samples securely at low temperatures, including vapor phase Liquid Nitrogen with Thermo Scientific™ Matrix™ 500μL ScrewTop tubes. These tubes are molded from medical grade resins and feature a permanent, high contrast 2D barcode. Used in combination with Thermo Scientific™ VisionMate™ 2D barcode readers, manual and automated capping equipment, and labeling options, the 2D ScrewTop Tubes meet a range of manual and automated long term storage needs.
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 acrylonitrile butadiene styrene (ABS) to protect tubes in case of accidental dropping
- ScrewTop Tubes are compatible with storage down to -196°C
Secure Tracking
- Permanent, unique 2D barcode is laser-etched on the bottom of each tube
- 2D barcode allows you to scan and decode tubes at once without removing them from the rack, and allows data to be associated with each tube
- Compatible with our range of 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 a time
Stringent Quality Control
- Every 2D barcode is scanned for readability
- Every 2D barcode is checked against the database of all previous Thermo Scientific 2D barcodes to ensure there are zero duplicates
- Each tube is leak tested to ensure tube integrity and sample security
- All tubes are supplied free from DNA, RNase, DNase, endotoxins and cytotoxins

Frequently Asked Questions (FAQs)
Here are some advantages of the 2D barcoded storage system:
- Less time needed for labeling, sample recording, and retrieval
- Maximize freezer utilization while keeping storage space organised
- Ensures a safe, permanent ID of a sample
- Enables multivial capping and multichannel filling
- Individualized samples, eliminating multiple freeze/thaw cycles
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.
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
