The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) requires the purchase of two new Triple Multitron Standard Incubation Shakers with Top Cooling to replace non-functional units. Each unit must consist of three stacked incubation shakers within a small footprint, not exceeding 43 inches wide and 35 inches deep, and must fit through standard laboratory doors. Key performance requirements include independent temperature control from 15°C below ambient to 65°C, capacity for 6 x 5L flasks per shaker, and independent speed control. Additional features needed are a single bearing eccentric drive for quiet operation, enclosed shaking mechanism, and four blowers for temperature uniformity. The location for performance is the NIDDK laboratory, and no budget amount or submission timeline is specified.
