Hematology Centrifuge

The Hematocrit Centrifuge(DM1424) is a specialized high-speed benchtop centrifuge designed for hematocrit determination, packed cell volume (PCV) measurement, and micro-volume blood sample processing in clinical diagnostic and research laboratories . Operating at speeds from 200 to 14,000 rpm (up to 18,620 × g) with a maintenance-free brushless DC motor, this centrifuge features a dedicated AC24P hematocrit rotor for 24 × standard capillary tubes (12,000 rpm max) used for determination of erythrocyte volume fractions in blood and for separation of micro blood and solutions . An optional A24-2P microtube rotor (24 × 1.5/2.0 mL tubes, 14,000 rpm max) enables the same instrument to serve as a general-purpose microcentrifuge for DNA/RNA extraction, protein separation, and PCR sample preparation .

For the hematologist and clinical laboratory scientist, the DM1424 enables precise measurement of hematocrit (HCT) and packed cell volume (PCV)—critical diagnostic parameters for screening and monitoring anemia, polycythemia, dehydration, and other hematological disorders . The micro-volume capability makes this centrifuge ideal for neonatal bilirubin testing (photometric determination of bilirubin content in neonate blood samples for jaundice management), pediatric hematology, and critical care patients where blood conservation is essential . Additional clinical applications include doping tests, veterinary hematology, infant vitamin testing, and general clinical diagnostic testing .

The centrifuge features microprocessor-controlled operation with precise speed increments (10 rpm), LCD display with speed/RCF switchover, programmable run times (30 seconds to 99 minutes or continuous), and timer logic that commences once set speed is reached for accurate separation times . The PULSE key enables instantaneous quick spins, while parameters can be modified after set speed is reached without stopping the centrifuge . The lid automatically releases when operation has stopped, and a sound alert signals run completion .

Safety features include door interlock (prevents operation with open lid), over-speed detection, over-temperature detection, and automatic internal diagnosis, with CE, cTUVus, and FCC safety certifications . The centrifuge has passed MCA test according to IEC/EN61010-2-20 including explosion-proof and bio-safe tests, and complies with EN61010-2-101:2002 requirements for In Vitro Diagnostic (IVD) medical equipment .

With a compact footprint (approximately 15 × 11 × 11 inches), lightweight design (22 lbs), 2-year manufacturer warranty, and quiet, stable operation, the DM1424 provides reliable, specialized performance for hematocrit determination, PCV measurement, neonatal bilirubin testing, and micro-volume blood processing—supporting patient diagnosis across clinical hematology, neonatology, pediatrics, oncology, and transfusion medicine .
