When choosing a vacuum centrifugal concentrator, you need to consider the following core indicators:
Temperature control accuracy: DNA/RNA is sensitive to temperature, so you need to choose a model with precise temperature control (room temperature -75℃±1℃) to avoid high temperature damaging nucleic acid activity. Some high-end models support programmed gradient temperature control and are suitable for different solvents.
Vacuum system performance: The vacuum degree must reach ≤1 mbar, and it is equipped with an intelligent pressure relief function to prevent sample bubbling or boiling. It is recommended to choose a vacuum pump with molecular sieve drying and filtration to avoid water vapor backflow and contamination of samples.
Centrifugal force and adaptability: The centrifugal force range is recommended to be 2000-3000×g, compatible with 1.5mL/2mL centrifuge tubes, 96-well plates and deep-well plates. High-throughput models should support the processing of ≥48 tubes of samples at one time.
Anti-cross-contamination design: Models equipped with a HEPA filtration system are preferred to ensure that the exhaust gas is efficiently filtered to avoid aerosol contamination.
Operational convenience and safety: Choose equipment that is easy to operate, safe and reliable, and has low maintenance costs. A good supplier should provide comprehensive after-sales service to ensure timely help and support during use.
