AnTing DL-6000B Low-Speed Refrigerated Centrifuge

Overview

The AnTing DL-6000B is a benchtop low-speed refrigerated centrifuge engineered for high-capacity, temperature-controlled sedimentation of biological, clinical, and industrial samples. It operates on the principle of sedimentation under controlled gravitational force (RCF), where differential particle density and size enable separation of suspended components in liquid media. Designed for routine applications requiring gentle yet robust separation—such as cell pelleting, serum/plasma preparation, and polymer or colloidal suspension clarification—the DL-6000B delivers stable thermal management and mechanical reliability across extended operational cycles. Its maximum rotational speed of 6000 rpm generates up to 7500 × g, sufficient for most low-to-moderate density separations without inducing excessive shear stress on sensitive biomolecules or intact cells. The integrated refrigeration system maintains sample integrity by sustaining temperatures between −20 °C and +30 °C, with real-time monitoring and ±2 °C thermal accuracy—critical for preserving enzyme activity, nucleic acid stability, or antibody conformation during processing.

Key Features

• Reinforced polymer chassis providing structural rigidity while minimizing overall mass and vibration transmission
• Microprocessor-controlled temperature regulation with dual-stage Peltier cooling and forced-air circulation for uniform chamber thermal distribution
• Electronic safety door interlock with automatic rotor deceleration upon lid opening—compliant with IEC 61010-2-020 requirements for centrifuge safety
• Programmable timer (0–99 minutes) with auto-stop and audible end-of-run alert
• Brushless DC drive motor ensuring low maintenance, high torque at low speeds, and extended service life
• Horizontal swing-out rotor configuration supporting four 500 mL bottles or equivalent tube formats (e.g., 4 × 250 mL, 8 × 100 mL, or 16 × 50 mL), optimized for high-volume clinical or bioprocessing workflows
• Real-time display of speed (rpm), relative centrifugal force (×g), elapsed time, and chamber temperature

Sample Compatibility & Compliance

The DL-6000B accommodates standard polypropylene, polycarbonate, and glass containers compatible with low-speed centrifugation—including conical-bottom centrifuge bottles, blood collection tubes, and custom process vessels rated for ≥7500 × g. It supports ISO 13485-aligned quality systems and meets essential electrical safety standards per IEC 61010-1 and IEC 61010-2-020. While not certified for GLP/GMP environments out-of-the-box, its electronic log functionality (time-stamped run records) and password-protected parameter settings provide foundational traceability suitable for audit-readiness in regulated laboratories. The unit is designed for use in ambient environments with ≤80% non-condensing humidity and adequate ventilation for heat dissipation.

Software & Data Management

The DL-6000B features embedded firmware with local data retention: each completed run stores timestamp, set parameters (speed, time, temperature), and final status (normal stop, emergency halt, or error code). No external PC interface or proprietary software is required; however, manual recordkeeping can be augmented via optional RS-232 or USB-to-serial adapters for integration into LIMS or electronic lab notebook (ELN) platforms. All user-modifiable settings are protected by a two-level access control system (operator vs. administrator), supporting compliance with FDA 21 CFR Part 11 principles where handwritten logs are supplemented by digital backups.

Applications

• Clinical diagnostics: Serum separation from whole blood, urine sediment concentration, and CSF clarification
• Biopharmaceutical manufacturing: Harvesting mammalian or microbial cells prior to lysis or filtration steps
• Food & beverage QA/QC: Fat separation in milk homogenates, yeast removal in fermentation broths, and starch granule isolation
• Environmental testing: Solid-liquid separation of wastewater sludge or soil extracts
• Academic research: Preparative isolation of organelles (e.g., nuclei, mitochondria) using differential centrifugation protocols
• Veterinary labs: Equine serum processing, avian egg yolk fractionation, and tissue homogenate clarification

FAQ

What is the minimum achievable temperature, and how quickly does the chamber reach setpoint?
The refrigeration system achieves −20 °C nominal; stabilization time depends on ambient conditions and rotor load but typically requires 15–25 minutes from room temperature.
Is rotor imbalance detection included?
Yes—the drive electronics continuously monitor current draw and vibration signatures; automatic shutdown occurs if imbalance exceeds safe thresholds per ISO 15521-1.
Can this centrifuge accommodate fixed-angle rotors?
No—the DL-6000B is configured exclusively for horizontal swing-out rotors; no fixed-angle or microplate adapters are supported.
Does it support continuous operation mode?
No; all runs are timer-limited to 99 minutes maximum, with mandatory cooldown and rest intervals recommended between successive high-load cycles.
What maintenance is required for long-term reliability?
Routine cleaning of condenser coils and chamber interior, annual calibration of temperature sensors and speed encoder, and biannual inspection of door latch mechanism and rotor spindle bearings.
