IBIs PR-42 has four fluorescent orange angled shelves that ensure your pipettes remain safely in place, while adding a touch of color to your lab. The notched shelves also offer easy access to many different pipette lengths. Depending on the size of the pipette, the four compartments offer approximately double the storage volume over competitive racks. A bottom miscellaneous storage compartment increases the racks stability, and the skid proof feet keep the rack from sliding on your bench top. Each Compartment measures 6-1/2" width x 3" height. Measures 7" width by 16-1/4" height by 11-3/4" depth.
