DESCRIPTION

The DNA SpeedVac ^TM, model DNA110, is a dedicated centrifugal vacuum concen­tration system for drying low-volume ethanol or methanol-water precipitates of DNA and RNA. The DNA SpeedVac ^TM combines centrifugal force with vacuum for bump-free sample concentration. Vacuum is supplied by an Integral, oil-free/ maintenance-free vacuum pump with an automatic bleeder valve.

The DNA SpeedVac ^TM has a chamber heater that counteracts evaporative sample cooling and accelerates drying rate. The Operator can select Low (ambient), Medium (43°C), or High (65°C) drying rates with the three-position switch an the front panel.

Rotors are available with sample tube capacities of either 24 x 1.5 ml or 48 x 0.5 ml for drying ethanol precipitates of DNA/RNA, methanol-water mixtures, amplified reaction products in buffer, aliquots of radiochemicals, or other low-volume samples.

The DNA SpeedVac ^TM is equipped with vacuum-type polypropylene vacuum fittings to avoid leaks and resist corrosion. A chemical trap kit (DTK120R) and disposable cartridge (DC 120R) are available for trapping organic solvent vapors and volatile radioactivity; the DTK120A kit and DC 120R cartridge are available for trapping acids.
