Xiangyi GL-10MD High-Capacity High-Speed Refrigerated Centrifuge

Overview

The Xiangyi GL-10MD is a floor-standing, high-capacity refrigerated centrifuge engineered for demanding preparative separation tasks in biotechnology, pharmaceutical development, and academic research laboratories. It operates on the principle of sedimentation under controlled gravitational force (RCF), enabling efficient isolation of subcellular components—including organelles, viruses, nucleic acids, and large protein complexes—from large-volume biological samples. With a maximum rotor speed of 10,000 rpm and an achievable relative centrifugal force of 18,300 × g, the GL-10MD delivers robust performance for macromolecular fractionation protocols requiring both thermal stability and mechanical reproducibility. Its integrated refrigeration system maintains sample temperature between –20 °C and +40 °C during operation, minimizing enzymatic degradation and preserving structural integrity—critical for downstream applications such as cryo-EM sample preparation, plasmid purification, and cell lysate clarification.

Key Features

• Horizontal swing-bucket rotor configuration supporting up to six 1000 mL centrifuge bottles (total capacity: 6 L per run), optimized for scalable process development and batch-wise clinical sample processing.
• High-strength 7075-T6 aerospace-grade forged aluminum rotor and centrifuge buckets, surface-treated with hard-anodization for enhanced corrosion resistance and long-term dimensional stability under repeated thermal cycling.
• Digital touch interface with real-time display of speed (rpm), RCF, time, temperature, and acceleration/deceleration profiles; automatic RCF calculation based on selected rotor radius and speed.
• Programmable multi-step protocols with storage for ≥20 user-defined methods, including ramp/brake rate control to prevent pellet resuspension or shear-sensitive sample damage.
• Comprehensive safety architecture: electronic imbalance detection, overspeed protection, motor overtemperature cutoff, automatic lid interlock, and emergency brake activation.
• Energy-efficient eco-refrigeration system using non-ozone-depleting refrigerant (R134a or equivalent), achieving ≤±1 °C temperature accuracy across full operational range and maintaining setpoint stability even at maximum load.
• Acoustically damped cabinet design yielding noise emission <65 dB(A) at 1 m distance—compliant with ISO 7779 and IEC 60705 standards for laboratory equipment noise limits.

Sample Compatibility & Compliance

The GL-10MD accommodates standard ISO-compliant 1000 mL polypropylene or stainless-steel centrifuge bottles, with optional adapters for 500 mL, 250 mL, and 50 mL formats. All rotors are certified to ISO 15189 and ASTM F2119 for rotational integrity under continuous duty cycles. The instrument meets IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking for EMC and LVD compliance. For regulated environments, it supports audit-ready documentation packages—including material traceability records (chemical composition, tensile strength, ultrasonic flaw detection), calibration certificates, and factory test reports aligned with GLP/GMP expectations.

Software & Data Management

While the GL-10MD operates via embedded firmware without external PC dependency, its control system logs timestamped operational metadata—including run ID, rotor serial number, start/stop time, final RCF, temperature profile, and fault codes—for local export via USB interface. Data files conform to CSV format for integration into LIMS or ELN platforms. Optional RS-232 or Ethernet connectivity enables remote monitoring and centralized fleet management in multi-instrument facilities. Firmware updates follow secure signed-binary protocols compliant with FDA 21 CFR Part 11 principles for electronic record integrity.

Applications

• Large-scale purification of monoclonal antibodies and viral vectors in upstream bioprocessing.
• Isolation of exosomes and extracellular vesicles from plasma, serum, or conditioned media.
• Clinical hematology workflows including platelet-rich plasma (PRP) and buffy coat separation.
• Environmental microbiology: concentration of waterborne pathogens (e.g., Cryptosporidium, Giardia) from 1–2 L filtration eluates.
• Plant and microbial cell harvesting prior to lysis and metabolite extraction.
• Preparative ultracentrifugation support—serving as a high-throughput pre-clearing step before density gradient or sucrose cushion ultracentrifugation.

FAQ

What is the maximum permissible sample volume per run?
The GL-10MD supports up to 6 × 1000 mL containers, totaling 6 liters per centrifugation cycle when using the standard horizontal rotor.
Does the centrifuge comply with international safety and electromagnetic compatibility standards?
Yes—it conforms to IEC 61010-1, IEC 61326-1, and carries CE marking for Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) requirements.
Can rotor calibration data be traced to national metrology institutes?
Each rotor is supplied with a unique serial-numbered calibration certificate referencing traceable torque and balance verification against NIM (National Institute of Metrology, China) standards.
Is remote diagnostics or firmware update capability available?
Firmware updates are performed locally via USB; remote diagnostic support requires optional network module installation and authenticated access through authorized service channels.
What documentation is provided for GxP-regulated environments?
Xiangyi supplies full DQ/IQ/OQ documentation templates, material certification dossiers, and maintenance logbooks compatible with FDA 21 CFR Part 11 and EU Annex 11 validation frameworks.
