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.
