Brookfield DL-6MS High-Capacity Refrigerated Floor-Standing Centrifuge

Overview

The Brookfield DL-6MS is a high-capacity, refrigerated floor-standing centrifuge engineered for large-volume biological sample processing in regulated and high-throughput laboratory environments. It operates on the principle of sedimentation under controlled gravitational force (RCF), enabling efficient separation of blood components, cell suspensions, microbial cultures, and biopharmaceutical intermediates. Designed specifically for applications requiring batch processing of up to 7.2 L per run (6 × 1,200 mL), the DL-6MS integrates precision temperature control (−20 °C to +40 °C), high-torque AC frequency-controlled motor drive, and robust mechanical architecture—making it suitable for central blood banks, GMP-compliant bioprocessing facilities, and large-scale academic core laboratories.

Key Features

• High-capacity horizontal rotor configuration supporting dual-use protocols: 6 × 500 mL at full speed (6,000 rpm / 6,680 × g) or 6 × 1,200 mL at optimized low-speed separation (4,200 rpm / 5,100 × g).
• Microprocessor-based control system with large backlit LCD touchscreen interface; supports intuitive navigation, multi-step protocol programming, and automatic parameter retention across power cycles.
• Imported high-efficiency compressor unit utilizing environmentally compliant R404a refrigerant; achieves stable thermal equilibrium within ±1 °C across the full operating range, critical for plasma fractionation and cold-sensitive biomolecule isolation.
• Real-time RPM ↔ RCF conversion display and setpoint adjustment—eliminates manual calculation errors during method transfer or SOP execution.
• Comprehensive safety architecture including electromagnetic lid interlock, dynamic imbalance sensing, overspeed cutoff, overtemperature shutdown, and self-diagnostic alarm logging compliant with IEC 61010-2-020 safety standards for laboratory centrifuges.
• Ten independently configurable acceleration and deceleration ramp profiles—enabling optimization of shear-sensitive separations (e.g., platelet-rich plasma or exosome pellets) without vortexing or resuspension.

Sample Compatibility & Compliance

The DL-6MS accommodates standard polycarbonate and stainless-steel buckets compatible with ISO-certified conical tubes (50 mL, 100 mL, 250 mL, 500 mL, and custom 1,200 mL formats). Its rotor geometry and balance tolerance meet ISO 15189 requirements for clinical laboratory equipment validation. The instrument’s temperature stability profile supports workflows aligned with CLSI GP44-A4 (centrifuge performance verification) and EU Annex 1 (sterile product manufacturing), particularly in blood banking where component separation must occur at ≤4 °C or ≤22 °C depending on leukoreduction or cryoprecipitate protocols. All firmware and operational logs are timestamped and non-erasable—facilitating GLP/GMP audit readiness and FDA 21 CFR Part 11 compliance when integrated with validated LIMS environments.

Software & Data Management

No proprietary software installation is required—the DL-6MS operates as a standalone instrument with embedded firmware that stores up to 100 complete run records (including date/time stamp, rotor ID, speed, time, temperature, and final RCF). Each protocol includes editable metadata fields (e.g., operator ID, sample type, batch number) for traceability. Export functionality via USB port enables CSV-formatted data transfer for integration into ELN systems or statistical process control (SPC) platforms. Firmware updates are performed offline using signed binary files, ensuring integrity and version control in regulated settings.

Applications

• Blood bank operations: Separation of whole blood into packed red cells, platelet concentrates, fresh frozen plasma, and cryoprecipitate under strict temperature control.
• Biopharmaceutical downstream processing: Clarification of mammalian cell culture harvests prior to filtration or chromatography steps.
• Vaccine manufacturing: Harvest and concentration of viral vectors or bacterial lysates at scalable volumes.
• Academic research: High-yield isolation of extracellular vesicles, organelles, or macromolecular complexes from tissue homogenates or fermentation broths.
• Environmental microbiology: Concentration of waterborne pathogens (e.g., Legionella, protozoan cysts) from large-volume samples prior to PCR or culture analysis.

FAQ

What is the maximum certified load capacity for continuous operation?
The DL-6MS is validated for continuous operation at 6 × 1,200 mL (7.2 L total) at 4,200 rpm and 5,100 × g. For higher RCF applications, the 6 × 500 mL configuration is rated for 6,000 rpm (6,680 × g) with a 15-minute maximum dwell time per run.
Does the instrument support remote monitoring or network connectivity?
No built-in Ethernet or Wi-Fi interface is provided; however, USB-based data export and external PLC-triggered start/stop signals (via dry-contact I/O port) enable integration into automated lab workflows.
Are rotors and adapters supplied with CE or ISO 13485 certification documentation?
Yes—each rotor assembly is supplied with individual calibration certificates traceable to NIST standards, and material declarations (RoHS, REACH) are available upon request.
Can the temperature be maintained during rotor acceleration?
Yes. Pre-cooling mode engages the compressor before rotor spin-up, and active cooling remains engaged throughout the entire run—including acceleration, hold, and deceleration phases—to prevent thermal drift.
Is service support available outside mainland China?
BIORIDGE maintains authorized service partners in Southeast Asia, the Middle East, and Latin America; technical documentation and spare parts logistics comply with ISO 9001 service management standards.
