5 mL/ 15mL/ 17mm Tube Rack

Manufacturer: Heathrow Scientific

Rotate with ease to accommodate your needs

With bench top space at a premium, it’s important for research and clinical labs working across a range of applications to efficiently use the space available. Unlike other tube racks, these multi-purpose racks are specifically designed with the flexibility to hold multiple tube sizes firmly in place to assist technicians constantly alternating between sample vessels.

The rack incorporates two moving hinged shelves that can be rotated to an up or down position to accommodate the size of the tube being used. When working with samples, the shelves can be rotated to an angle position to facilitate more comfortable pipetting and allow better visibility. The tube rack wells have a unique teardrop design that enables easier insertion and better retention of tubes over traditional designs.

Two tube rack versions are available:

  • For Research Labs: The 5mL/15mL/17 mm tube rack comes with TWO tube segments
  • For Clinical Labs: The 10-17 mm Tube Rack comes with FOUR interchangeable tube segments.

Additional Features:

  • Ergonomic handles for ease of transporting the rack
  • Molded grid on both sides of the shelves for quick sample identification and retrieval
  • Autoclavable
