Roto-Therm series of incubated rotating mixers provide a wide range of mixing capabilities. Suitable for an array of laboratory applications including re-suspension, protein binding, nucleic acid purification, histochemistry, hybridization etc, the mixers include interchangeable tube holders for accommodating all common tube sizes from 0.5ml to 50ml. The motion can be adjusted from vertical (end over end) mixing, to horizontal (rolling or hybridization style) mixing. For applications requiring temperature control, the Roto-Therm series can be digitally programmed to maintain chamber temperatures of ambient +5°C to 60°C and include an “in-lab” calibration function for ensuring accurate temperature control. The Roto-Therm is also available in a “Plus” configuration, providing the following additional features: Variable speed: 5 to 70rpm “Mix” function: Rotating in combination w/ oscillations (increased mixing) “Pause” function: Rotating with intermittent “stops” during rotation “Rock” function: Back and forth, gentle rocking motion (see-saw) The Plus model also offer an additional rocking platform (4.5 x 3 in.), as well as a 96 x 0.2ml tube/strip/plate holder for mixing PCR vessels in the “Mix” (oscillating) mode. Specifications: Temperature: Ambient +5 to 60°C Speed (RS2020): 24rpm Speed (RS2024): 5 to 70rpm Mixing Modes (RS2024): Mix, Pause, Rock Dimensions: 11.8 x 8.5 x 9in (29.5 x 21.6 x 22.9cm) Weight (RS2020): 9 lbs (4kg) Weight (RS2024): 10 lbs (4.5kg)
