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
Screw top Tubes are compatible with storage down to –176 °C

Tubes are molded from medical grade resins and feature a permanent, high contrast 2D,1D linear and human readable barcode.

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

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

: Products are manufactured in ISO 7 class clean room environment according to ISO 14644-1:2015. Sterile products are sterilized by gamma irradiation according to ISO 11137; 10⁻³ Sterility Assurance Level (SAL). The vials and closures were tested and met the requirements of USP <88> Class VI plastics.

: 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 screw top 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.
