The ThermoSavant DNA Speed Vacuum Model DNA 120, is a dedicated centrifugal vacuum concentration system for drying low volume ethanol or isopropanol-water precipitates of DNA and RNA. This design incorporates a glass cover, ammonia post-trap and Ammonia Neutralizing Solution for fully automated, unattended, odor-free drying. The post-trap is connected on the back, left side of the unit. It is easily maintained and replaced. The Savant DNA SpeedVac combines centrifugal force with vacuum for bump-free sample drying. Vacuum is supplied by an integral, oil-free vacuum pump with an automatic bleeder valve.
The Savant DNA120 SpeedVac has a chamber heater that counteracts evaporative sample cooling and accelerates solvent evaporation rates to shorten drying times. The operator can select LOW (ambient), MEDIUM (43 °C), or HIGH (65°C) drying rates with the 3-position switch on the front panel.
The Savant DNA SpeedVac is equipped with polypropylene vacuum fittings to avoid leaks and resist corrosion. A chemical trap kit (DTK120R) and disposable cartridge (DC120R) should be used for trapping volatile radioactivity when the system is dedicated for drying down radio labeled materials.
This DNA120 SpeedVac comes with a RD36 rotor. Please inquire if you need another rotor.
