What does the Vacufuge do?
The Eppendorf Vacufuge plus assures quick, efficient and gentle vacuum concentration of DNA/RNA, nucleotides, proteins and other liquid or wet samples. It fits comfortably right on a lab bench. The Vacufuge plus is available with three configurations to meet the customers’ lab-specific needs.
How does a vacuum centrifuge work?
In a vacuum concentrator, samples are held in a rotor that spins at 1700 RPM creating a centrifugal force. The centrifugal force prevents liquids from bumping out of the tube when vacuum is applied. Heat is applied indirectly through the walls of the vacuum chamber.
What is vacuum concentrator?
Used in proteomics, genomics, cell biology, microbiology, and drug development, a vacuum centrifuge concentrator uses a vacuum, centrifugal force, and sometimes heat or gas blow down to evaporate liquid and concentrate DNA, RNA, nucleotides, and other proteins for further use or study. …
What is a centrifugal evaporator used for?
A centrifugal evaporator is a device used in chemical and biochemical laboratories for the efficient and gentle evaporation of solvents from many samples at the same time, and samples contained in microtitre plates. If only one sample required evaporation then a rotary evaporator is most often used.
What is a refrigerated centrifuge used for?
Refrigerated centrifuges are used for samples that need a consistent range of temperature. With such centrifuges therefore; it is essential that they run at maximum speeds while still maintaining a consistent temperature. For the most part, the temperature range of refrigerated centrifuges is between -20 and -40c.
What is a speed vacuum?
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.
Why nitrogen is used for evaporation?
Pure, dry nitrogen is commonly used to evaporate solvents, as it is a relatively non-reactive gas; in contrast air contains oxygen and water vapor, which could react with the compounds of interest.
Do evaporators need electricity?
The energy consumption for single-effect evaporators is very high and is most of the cost for an evaporation system. Putting together evaporators saves heat and thus requires less energy.
What is centrifuge used for in the laboratory?
Centrifuges are used in various laboratories to separate fluids, gases, or liquids based on density. In research and clinical laboratories, centrifuges are often used for cell, organelle, virus, protein, and nucleic acid purification.
What are the functions of laboratory centrifuge?
A laboratory centrifuge is a rotor driven instrument designed to separate liquid samples at high rates of speeds. The rotation of the centrifuge induces centripetal acceleration and separates substances based on density.

What is the suction capacity of the concentrator plus vacuum pump?
In order to ensure the functionality of the Concentrator plus, an external vacuum pump must have a suction capacity of at least 1.9 m³/h at 50 Hz or 2.1 m³/h at 60 Hz. Each pump used should be able to contain a maximum ultimate pressure of at least <20 hPa (<20 mbar). The vacuum pump should also be resistant to chemicals.
