When built-in temperature control is not needed, Excella open-air shakers are the solution. Ruggedly-built for use on the bench, in an incubator, or in a warm- or cold-room, these shakers are available in three sizes. The Excella microprocessor controlled, heavy-duty counterbalanced drives provide years of continuous, quiet operation. Excella shakers are available with a large selection of accessories to accommodate a wide range of flasks, test tubes and general labware. Like most New Brunswick shakers, Excella platforms, clamps and accessories are interchangable. Microprocessor-controlled E5 accommodates flasks up to 6 L on an 18" × 18" accessory platform.
