D6A (item number: D6A) is a universal desktop low-speed centrifuge that balances large capacity and high efficiency. The original intention of its design is to meet the diverse needs of hospitals, blood stations, and research laboratories in the analysis and testing of serum, plasma, urine, and radioimmunoassay.
As a medium to large capacity model, the D6A can reach a maximum speed of 6000r/min and a maximum capacity of 4 × 300ml, which can handle batch sample processing and is suitable for routine inspection work.It adopts a spring cone sleeve to connect the patented and aviation forged aluminum rotor, greatly improving the efficiency and safety of loading and unloading.
At the same time, combined with automatic balancing, three-level vibration reduction, and multi-layer protection, it can operate stably even at high speeds and large capacities.
D6A can be configured with multiple horizontal rotors, angle rotors, and enzyme-linked immunosorbent assay plate rotors, covering 2ml to 300ml tube types, truly achieving "one machine for multiple uses".
