The 64-place freezer storage rack is designed to replace 5¹/₄×5¹/₄" cardboard freezer storage boxes.

• Rack holds up to 64 tubes in an 8×8 matrix
• Produced from copolymer polypropylene
• Withstands limited autoclaving (up to 15 minutes) as well as deep freezer storage (down to –90 °C)
• Both sides are labeled with a large easy-to-read 1 to 8 by A-H matrix

Designed to be reversible; one side has holes suitable for the larger tubes the other has holes suitable for smaller size microtubes. The hole spacing is greater than with the standard 80-place rack making it possible to store tubes in all 64 holes simultaneously.

Great substitute for cardboard or metal freezer racks:
Side A: Holds 64×1.5/2.0 ml tubes
Side B: Holds 64×0.5 ml tubes
