Overview
The DLAB DM0306 is a compact, benchtop low-speed centrifuge engineered for routine separation tasks in clinical, diagnostic, and academic laboratories. It operates on the principle of sedimentation under controlled gravitational force—generating up to 1600 × g at a maximum rotational speed of 3400 rpm—to efficiently separate whole blood into serum or plasma fractions, isolate cellular components, and clarify suspensions. Its design prioritizes operational safety, spatial efficiency, and reproducible performance in high-throughput sample preparation workflows. Unlike high-speed or ultracentrifuges, the DM0306 is optimized for applications where moderate g-force suffices—such as clinical hematology, blood bank processing, and basic cell culture supernatant clarification—without introducing excessive shear stress or thermal load on temperature-sensitive biological specimens.
Key Features
- Compact footprint (359 × 318 × 222 mm) ideal for crowded lab benches or mobile diagnostic units.
- SE6-10P fixed-angle rotor accommodating six standard blood collection tubes (3–10 mL), compatible with common evacuated tube formats including EDTA, heparin, and serum separator tubes (SST).
- LED display with real-time countdown timer (0.5–30 min resolution) and continuous mode selection; intuitive interface requires no software training.
- Programmable deceleration profiles: three distinct brake settings—including soft-brake mode—to minimize pellet disturbance during tube deceleration, critical for fragile cell layers or viscous samples.
- Integrated safety architecture: automatic lid interlock prevents operation with an unlatched cover; mechanical latch remains functional even during power loss; transparent polycarbonate lid meets EN 61010-1 impact resistance standards.
- Brushless AC motor ensures stable speed regulation, low maintenance, and extended service life (>10,000 h MTBF); power consumption capped at 80 W across dual-voltage input (110–120 V / 220–240 V, 50/60 Hz).
- Noise emission limited to ≤63 dB(A) at 1 m distance—compliant with ISO 15714:2017 laboratory acoustic environment guidelines.
Sample Compatibility & Compliance
The DM0306 supports routine handling of human and animal biofluids under CLIA-, CAP-, and ISO 15189-aligned preanalytical protocols. Its rotor geometry and acceleration profile are validated for use with commercially available 3–10 mL vacuum tubes meeting ISO 6710 specifications. The device complies with IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking for the European Economic Area. While not designed for biosafety level 3 (BSL-3) containment, its sealed rotor chamber and drip-resistant housing meet general biosafety best practices for BSL-2 environments. All mechanical and electrical components undergo factory calibration traceable to NIST-certified standards.
Software & Data Management
The DM0306 operates as a standalone instrument with no embedded firmware-based data logging or network connectivity. All operational parameters—including run time, speed, and brake setting—are manually selected via front-panel controls and retained only during active session. For laboratories requiring audit trails or electronic recordkeeping, integration with external LIMS or ELN systems is achieved through manual entry or barcode-scanned protocol referencing. The absence of digital storage aligns with FDA 21 CFR Part 11 “non-electronic record” classification, eliminating validation burden for GLP/GMP-regulated facilities where paper-based SOP execution is standard practice.
Applications
- Clinical laboratories: Serum/plasma separation from whole blood prior to immunoassay, clinical chemistry, or coagulation testing (e.g., PT, aPTT).
- Blood banks: Routine processing of donor units for component separation (RBC, platelet-rich plasma, cryoprecipitate).
- Medical education: Hands-on instruction in centrifugation principles, rotor dynamics, and preanalytical variables affecting hematocrit and fibrinogen yield.
- Research core facilities: Preliminary clarification of cell lysates, bacterial pellets, or tissue homogenates prior to downstream analysis (e.g., Western blot, ELISA, PCR).
- Point-of-care diagnostics: Deployment in field-deployable labs or mobile health units where reliability, low power draw, and minimal servicing are essential.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the DM0306?
The instrument delivers a maximum RCF of 1600 × g at 3400 rpm with the supplied SE6-10P rotor.
Can the DM0306 accommodate 15 mL conical tubes?
No—the SE6-10P rotor is dimensionally optimized for cylindrical blood collection tubes (3–10 mL). Use of non-specified tubes may compromise balance, safety, and separation efficiency.
Is the rotor autoclavable?
The SE6-10P aluminum rotor is not autoclavable; cleaning is performed with 70% ethanol or mild detergent followed by air drying. Autoclaving would degrade anodized surface integrity and void warranty.
Does the DM0306 support programmable protocols or memory recall?
It does not store user-defined methods; all settings must be re-entered per run. This design reduces complexity and supports ISO 17025 clause 7.7.1 requirements for method control in accredited testing labs.
What regulatory documentation is provided with shipment?
Each unit ships with Declaration of Conformity (CE), Factory Calibration Certificate, Operating Manual (EN/ES/FR/DE), and Safety Instructions compliant with IEC 61010-1 Edition 3.
