This rack is specially designed to hold all sizes of Whirl-Pak® bags. Made in the U.S.A. of 10 and 12-gauge steel fused together to create strong joints and straight lines. Rack is finished with an electrostatically applied powder coating. The result is a strong, durable finish which will stand up to many laboratory materials and allows the rack to be autoclaved. This double-grid rack provides a second horizontal bar below the top bar, keeping the bags from slipping sideways in the rack. Overall Dim.: 10" x 10" x 3.5". Compartment size: 3" x 2-3/8".
