Tube Rack Rollers

Efficient and practical solution for tube roller workflows


Expand Capacity of Your Workflow

Each Tube Rack Roller accommodates 10 tubes, doubling or tripling the capacity of your tube roller equipment

  • Saves Process Time - large batch processing reduces the number of roller cycles required for lab procedures
  • Saves Money - handles more without the need to invest in multiple machines to process the same amount of tubes
  • Saves Valuable Space -  additional capacity especially helpful with limited incubator capacity

Precise and Efficient Tube Rolling

Tube holder axis is parallel to roller axis for pure horizontal rotation for controlled sample manipulation

  • Provides a Gentler Mix – Tube Roller Rack slows the effective RPM of the tube roller due to the larger rotation
  • Preserves Sample Integrity – Controlled, lower speed mitigates cell damage reducing sample errors such as Hemolysis

Versatile and Durable Solution

  • Organize samples pre and post mixing
  • Use as a storage tube rack for upright storage or submerse in an ice bath
  • Polypropylene construction is wear-resistant and offers reliable sterilization through autoclaving
