Key Features and Advantages
When investing in a SpeedVac concentrator like the dna120, understanding its core
features can help you maximize its utility.
Vacuum and Centrifugal Force Combination
A standout characteristic of Thermo Savant’s SpeedVac systems is the use of vacuum
pressure coupled with centrifugal force. This dual-action approach accelerates solvent
evaporation by lowering the boiling point of liquids under vacuum while spinning the
samples to prevent bumping and splashing. This method ensures even and complete
drying of samples, which is especially important for downstream applications like PCR or
mass spectrometry.
Temperature Control for Sample Integrity
One of the biggest concerns during sample concentration is overheating, which can
degrade sensitive biomolecules. The dna120 features precise temperature control,
allowing users to set optimal conditions tailored to their samples. This controlled heating
protects nucleic acids and proteins from denaturation, preserving their functionality for
subsequent experiments.
Adaptability to Various Sample Types
Whether you’re working with nucleic acids, peptides, or small molecules, the dna120
SpeedVac offers compatibility with various tubes, plates, and vials. This adaptability

For molecular biologists, concentrating nucleic acids without degradation is paramount.
The dna120 allows researchers to safely remove solvents from DNA or RNA samples,
concentrating them to the desired volume for use in PCR, cloning, or sequencing. Its
gentle evaporation minimizes the risk of nucleic acid shearing or loss.
Protein Sample Preparation
Proteins often require concentration before analysis by techniques such as SDS-PAGE or
mass spectrometry. The dna120’s controlled evaporation prevents protein denaturation
and aggregation, making it an excellent choice for proteomics workflows.
Small Molecule and Metabolite Analysis
In analytical chemistry, concentrating small molecules or metabolites from biological
fluids or extracts is a routine task. SpeedVac concentrators efficiently reduce sample
volumes without introducing contaminants, facilitating accurate mass spectrometry or
chromatography analysis.

Proper maintenance ensures the dna120 SpeedVac concentrator delivers consistent
performance over years. Here are some key points:
**Vacuum pump care:** Regularly inspect and replace pump oil or clean filters as
recommended.
**Rotor inspection:** Check for any signs of wear or imbalance before each run.
**Handling solvents:** Use the concentrator in a well-ventilated area, especially
when evaporating volatile or toxic solvents.
**Sample containment:** Always secure lids or caps on tubes to prevent aerosol
generation.
Following these guidelines will prolong the lifespan of your equipment and maintain a safe
working environment.
