Find samples stored in 15 ml tubes quickly without opening boxes. Even tubes at the back of the freezer are easy to reach with these sliding drawer racks. Each opening is lined with a plastic stabilizer that holds the tubes in place and protects the tubes from scratching or other damage during insertion or removal. The top tray that contains the stabilizers for each drawer can also be removed for storage of larger bottles, boxes, or other items. Each stainless steel rack has two drawers.
