Vacuum promotes solvent evaporation in the SpeedVac chamber. High performance vacuum pumps ensure the low pressures which are required for faster solvent removal. Heat is applied to the samples to accelerate the evaporation process. SpeedVac Vacuum Concentrators use built-in chamber heaters.
How does Speed Vac work?
Vacuum promotes solvent evaporation in the SpeedVac chamber. Samples are maintained in liquid state at sub-ambient temperature throughout the concentration process, preventing loss of activity or damage to heat sensitive substances.
How long does it take to speed vac?
We have tried SpeedVac without using heating and it took ~2 hours to get to the volume we needed.
How does a vacuum evaporator work?
The vacuum evaporation treatment process consists of reducing the interior pressure of the evaporation chamber below atmospheric pressure. This reduces the boiling point of the liquid to be evaporated, thereby reducing or eliminating the need for heat in both the boiling and condensation processes.
What is speed Vac concentrator?
Thermo Scientific Savant SpeedVac vacuum concentrators, refrigerated vapor traps and pumps use state-of-the-art centrifugation, vacuum and heat technologies for removing solvents and concentrating samples while maintaining sample integrity.
What does a vacuum concentrator do?
Evaporators using centrifugation, vacuum, and heat for removing solvents and concentrating samples while maintaining sample integrity; especially useful for strong acids and bases in combinatorial chemistry.
Can evaporation happen in a vacuum?
Vacuum evaporation is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal.
Does water boil under vacuum?
Water Boiling in a Vacuum. The water molecules have kinetic energy to begin with, but not enough to boil in the presence of air pressure. When we remove the air pressure, the most energetic water molecules become water vapor gas.
What is Speed Vac used for?
Description: Thermo Scientific Savant DNA SpeedVac concentrators are designed specifically for DNA and RNA applications. These compact, fully-integrated systems support the rapid and efficient concentration and drying of DNA/RNA samples, nucleic acids, PCR preps and synthetic oligos.
What is Speed Vac concentrator?
Does temperature drop in a vacuum?
If your vacuum chamber is thermally isolated, then the temperature of the water decreases because it is expanding adiabatically into the gas state. The loss of random translational kinetic energy to uniform translational kinetic energy equates to a decrease in the temperature of the system.
