This series of tubes is available either plain or with printed graduations and white marking area for sample identification. The caps do not have the attachment loops for users who prefer to remove the caps completely from the tubes when filling or sampling. These microcentrifuge tubes have all the other fine features stated in the general description. Perfect for cryogenic work. Non skirted tubes can be centrifuged up to 20,000g. Skirted tubes can be centrifuged up to 17,000g.

Will withstand temperatures from -196 °C to +121 °C. 

Tubes and caps (with CMT as part number) are certified RNase, DNase, DNA and Pyrogen free.

PolarSafe 2D tube

• PolarSafe 2D tubes are the ideal consumable for rapid processing of biological samples. The embedded Datamatix code inserted in the bottom of each tube corresponds to the "Code 128" barcode featured on the body of the tube. They provide time-saving and accurate organization and tracking of valuable samples.
  
  

• Innovative "channels of evacuation" designed between the tube and the 2D chip allows fluid to easily drain.
  
  
• The 2D tubes are offered in both 2 and 5mL sizes.
  
  
• Available with internally or externally threaded caps. 
  
  
• Certified DNase, RNase, and pyrogen free

The PolarSafe polycarbonate storage boxes

• The PolarSafe polycarbonate storage boxes work in conjuciton with the 2D tubes to provide automatic identification of both the box and stored vials.
  
  
• Each features a 2D Datamatrix code on the bottom of the box as well as a laser engraved Code 128 barcode on the side.
  
  
• Offered in both 81 and 100-well formats.
  
  
• PolarSafe 2D boxes are available in "short" (for 2mL tubes) and "tall" designs (for 5mL tubes).
