• Multi-Therm™ shaker is a temperature controlled vortexer, useful for a variety of molecular biology applications including denaturation of DNA, RNA and proteins, lipid extractions, reverse transcription, yeast and bacteria cultivation, DNA/plasmid isolation, restriction digests and gentle thawing of biological materials. • Speed range: 200 to 1500 rpm, or turn it off to use just the temperature control. Horizontally circular motion with a 2 mm orbit. • Speed, time and temperature are shown on the LCD, simultaneously showing actual and set values. • Heating ramp rate: 5°C/min. Cooling ramp rate: 2.5°C/min (779-830-04 only). • Temperature accuracy: ±1.0°C. • Precision contoured wells maintain uniform thermal transfer. • Integral over-temperature control ensures long life, safety and sample integrity. • Exchangeable blocks hold tube sizes from 0.2 to 50 ml. Blocks must be ordered separately. • Dimensions: 8.25” x 11.5” x 8.25”. Weight: 8 kg. • Power: 120 volt. * The larger mass of this block results in a reduced speed and temperature range (ambient minus 10 to 100°C).
