The DM0306 Low Speed Centrifuge and the Routine Blood-Tube Workflow

DM0306 Low Speed centrifuge

In clinical laboratories, the first processing decision is often tube format, not instrument capability. The DM0306 fixes its rotor around 6 × 3–10 mL blood collection tubes, covering the common draw sizes used for serum and plasma preparation.

Speed is fixed at 3400 rpm, equivalent to 1600 × g, with a single SE6-10P fixed-angle rotor. Because there is no speed selection, the workflow depends on a consistent protocol rather than operator calibration.

Timing runs from 30 seconds to 30 minutes on an electronic timer, with continuous operation available. An LED display shows remaining run time, which supports batch scheduling in small laboratories where multiple racks are processed in sequence.

Safety features include an automatic lid lock that prevents opening during operation, a mechanical lid lock to contain debris, and a transparent lid for observation. The specification states explosion-proof testing was passed and that the manual door lock can be released after stopping.

The unit is listed at 359 × 318 × 222 mm and 5.3 kg, powered by an AC fixed-frequency brushless motor drawing 80W across 115V and 200–240V configurations. Certifications cited are CE, UKCA, FCC, ICES, CB, and cTUVus.

Stated users include hospital laboratories, community hospitals, physical-examination centers, blood banks, medical schools, and research institutes. The catalog number field is blank in the specification, and speed accuracy and program memory are not stated, so buyers should confirm those details before purchase.

For a laboratory standardizing on blood tubes, the rotor capacity is the binding constraint. Any change in tube size or volume requires verifying the SE6-10P fit rather than assuming the instrument adapts.

Why it matters:
Fixed-speed, single-rotor centrifuges simplify training and repeatability but reduce flexibility. Procurement should confirm tube compatibility, voltage variant, and the blank catalog number before ordering.
