24-Place Microcentrifuge: The Laboratory Standard, Reimagined
The Sunny Peak microcentrifuge 5425 and 5425 R represent the next evolution of a true laboratory standard. These 24-place microcentrifuges combine whisper-quiet operation, outstanding versatility, and advanced cooling performance to handle the broadest range of molecular and cell biology applications — from Eppendorf tubes to PCR tubes in sizes from 0.2 mL to 5 mL.
The vented 5425 and refrigerated 5425 R are built on the trusted legacy of the 5424/5424 R series, retaining everything you loved while introducing new rotors and enhanced software functions that make everyday work smoother and more efficient.
Whisper-Quiet Performance for Routine Molecular Biology
The 5425 family has been engineered from the ground up to minimize noise without compromising on power. Short runs up to 12 minutes operate at an average of just 45 dB(A) — quiet enough that it stays unobtrusive in even the most noise-sensitive lab environments. With a maximum RCF of 21,300 × g, the 5425 delivers the separation force needed for the centrifugation steps of most routine DNA/RNA purification kits and other common molecular biology protocols.
During extended runs, the cooling fan works at full capacity to dissipate heat efficiently, maintaining optimal sample conditions throughout the entire process.
Advanced Cooling — Ready When You Are (5425 R)
The refrigerated 5425 R features an improved cooling system that maintains precise temperature control even at maximum rotor speed. It reaches 4°C quickly and reliably — keeping your temperature-sensitive samples safe and your separation results consistent.
With a pre-cooling time of just 8 minutes (from ~21°C to 4°C), the 5425 R is ready for operation the moment you are, eliminating long wait times before critical runs.
