Hematocrit Centrifuge(DM1424)

WhatsApp Order

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 .

Description

Hematocrit Centrifuge(DM1424)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Hematocrit Determination for Anemia and Blood Disorder Screening

Primary Use: Provides a specialized high-speed hematocrit centrifuge with a dedicated AC24P capillary rotor, used for determination of volume fractions of erythrocytes in blood and for separation of micro blood and solutions .
How it helps: For the hematologist and clinical laboratory scientist, the DM1424 enables precise measurement of packed cell volume (PCV) (also known as hematocrit, HCT)—a critical diagnostic parameter for screening and monitoring anemia, polycythemia, dehydration, and other hematological disorders . For the patient, accurate hematocrit values guide diagnosis of conditions such as iron deficiency anemia, sickle cell disease, and bone marrow disorders, enabling timely treatment initiation.

2. Neonatal Bilirubin Testing for Jaundice Management

Primary Use: Used to derive plasma from neonate blood samples for the photometric determination of bilirubin content, supporting diagnosis and monitoring of neonatal jaundice .
How it helps: For the neonatologist and pediatric clinical chemist, the DM1424’s ability to process micro-volume capillary blood samples (typically from a heel stick) enables rapid plasma separation for bilirubin measurement—critical for assessing jaundice severity and guiding phototherapy decisions in newborns. For the neonate, timely and accurate bilirubin testing prevents kernicterus (bilirubin-induced neurological damage) and supports early intervention for hyperbilirubinemia.

3. Micro-Volume Blood Separation for Pediatric and Critical Care

Primary Use: Operates at speeds up to 14,000 rpm in 10 rpm increments (maximum RCF 18,620 × g) with the ability to process micro-volume blood samples in capillary tubes, ideal for patients where blood conservation is essential .
How it helps: For the pediatric phlebotomist and critical care nurse, the DM1424’s specialized rotor design accommodates up to 24 capillary tubes simultaneously, processing micro-volume blood samples ideal for pediatric, neonatal, geriatric, and critical care patients where multiple blood draws could lead to iatrogenic anemia. For the patient, smaller blood volume requirements (typically 50-75 μL per capillary tube) reduce discomfort and minimize risk of anemia from repeated diagnostic blood draws.

4. Flexible Dual-Rotor Design for Multi-Purpose Laboratory Use

Primary Use: Equipped with AC24P rotor (24 × capillary tubes, 12,000 rpm max) for hematocrit applications, and can be fitted with optional A24-2P rotor (24 × 1.5/2.0 mL tubes, 14,000 rpm max) for routine microcentrifuge applications .
How it helps: For the laboratory manager and clinical hematologist, the DM1424’s dual-rotor capability eliminates the need for a separate microcentrifuge for DNA/RNA extraction and protein separation—allowing a single instrument to serve both specialized hematocrit testing and general molecular biology applications. For the patient, consolidating equipment reduces laboratory processing delays and supports faster turnaround for multiple test types.

SECONDARY & SUPPORTIVE USES

1. DNA and RNA Extraction and Purification: Using the optional A24-2P microtube rotor, supports spin column-based nucleic acid extraction for molecular diagnostics and PCR preparation .

2. Packed Cell Volume (PCV) Measurement: Provides direct determination of PCV for assessment of red blood cell mass and evaluation of blood loss, dehydration, and polycythemia .

3. Doping Tests and Sports Medicine: Used for hematocrit determination in anti-doping testing to screen for blood doping and erythropoietin abuse .

4. Veterinary Hematology: Processes micro-volume blood samples from companion animals (dogs, cats, horses) and laboratory animals for routine hematological analysis .

5. Infant Vitamin and Nutritional Status Testing: Used for separation of micro blood samples for vitamin analysis and nutritional assessment in pediatric populations .

6. Cerebrospinal Fluid (CSF) Cell Concentration: Concentrates cells from CSF samples for cytological examination in neurological diagnostics.

7. Urinalysis Sediment Preparation: Used for concentration of cellular elements from urine samples for microscopic examination.

Rotor Loading: Load tubes symmetrically; never run rotor with unbalanced loads .
Cleaning: Clean spills immediately; disinfect rotor chamber if biological materials are involved; do not pour water directly into rotor chamber.
Placement: Place on firm, flat, level surface; ensure the feet stand firmly on the table; avoid vibration around the instrument.
Training: Only trained laboratory personnel should operate the centrifuge.

2. FIRST AID MEASURES

Capillary Tube Breakage: If capillary tube breaks during operation, stop centrifuge immediately, allow rotor to stop fully, carefully remove glass fragments using forceps, disinfect rotor and chamber.
Sample Splash: If biological sample splashes, disinfect area immediately with appropriate disinfectant (e.g., 70% ethanol, bleach solution).
Imbalance Shutdown: If imbalance shutdown occurs, rebalance rotor equally, restart centrifuge.
