AnTing GL-12B High-Speed Refrigerated Benchtop Centrifuge

Overview

The AnTing GL-12B is a high-speed refrigerated benchtop centrifuge engineered for precision separation of biological, chemical, and pharmaceutical samples under controlled thermal conditions. It operates on the principle of sedimentation centrifugation—utilizing rotational force to separate particles based on density, size, and shape within a liquid medium. With a maximum rotational speed of 12,000 rpm and a peak relative centrifugal force (RCF) of 9,338 × g, the GL-12B delivers robust performance for demanding applications such as cell pelleting, subcellular fractionation, nucleic acid isolation, and protein purification. Its integrated refrigeration system maintains sample integrity across a wide operational temperature range (−20 °C to +30 °C), minimizing thermal degradation during extended runs. The unit complies with IEC 61010-1 safety standards for laboratory electrical equipment and incorporates an electronic door interlock mechanism to prevent accidental operation while the chamber is open.

Key Features

• Reinforced polymer housing ensures structural rigidity and vibration damping, contributing to operational stability at high speeds.
• Microprocessor-controlled temperature regulation with independent cooling circuitry enables rapid thermal equilibration and precise setpoint maintenance (±2 °C accuracy).
• Digital timer with 1-minute resolution supports repeatable run durations from 0 to 99 minutes, supporting standardized protocols in QA/QC environments.
• Electronic door lock system prevents lid opening during rotation and automatically halts acceleration if interlock integrity is compromised.
• Brushless DC motor delivers consistent torque delivery, low acoustic emission (<65 dB at 1 m), and extended service life without carbon brush replacement.
• Front-panel LED display provides real-time monitoring of speed (rpm), RCF, temperature, time remaining, and error codes.

Sample Compatibility & Compliance

The GL-12B accommodates standard fixed-angle rotors compatible with 15 mL, 50 mL, and 100 mL conical tubes—enabling efficient processing of clinical, microbiological, and research-grade samples. Its design permits use with common centrifuge-compatible plastics (polypropylene, polycarbonate) and glass vessels rated for ≥12,000 rpm. While not certified to ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the instrument’s deterministic control logic, non-volatile parameter storage, and audit-ready operational logs support integration into GLP- and GMP-aligned workflows when paired with documented SOPs. It meets electromagnetic compatibility (EMC) requirements per EN 61326-1 and carries CE marking for conformity with EU health, safety, and environmental protection directives.

Software & Data Management

The GL-12B operates via embedded firmware without external PC dependency; however, all run parameters—including speed, temperature, duration, and rotor identification—are stored in non-volatile memory for up to 100 recent cycles. Optional RS-232 serial interface (available upon request) allows connection to laboratory information management systems (LIMS) or custom data acquisition software for traceable record generation. Parameter recall functionality enables rapid re-execution of validated methods, reducing operator-induced variability. No proprietary software license or cloud subscription is required for basic operation or data export.

Applications

• Cell culture harvest and clarification in bioprocessing laboratories.
• Plasma and serum separation from whole blood in clinical diagnostics settings.
• Pelleting of bacterial and yeast cultures prior to lysis or genomic DNA extraction.
• Removal of insoluble aggregates from recombinant protein preparations.
• Preparative isolation of mitochondria, lysosomes, and other organelles using differential centrifugation protocols.
• Routine quality control testing of suspensions, emulsions, and colloidal dispersions in materials science labs.

FAQ

What rotor configurations are supported by the GL-12B?
The GL-12B is configured for fixed-angle rotors only; standard offerings include 4 × 100 mL, 8 × 50 mL, and 12 × 15 mL capacity variants—all balanced for operation at full rated speed.
Is the refrigeration system compressor-based or thermoelectric?
It employs a sealed R134a refrigerant compressor system optimized for continuous duty cycling between −20 °C and ambient conditions.
Can the GL-12B be operated without active cooling?
Yes—the temperature control can be disabled to run in ambient-mode centrifugation, though RCF performance remains unchanged.
What maintenance intervals are recommended?
Rotor inspection every 500 hours of cumulative operation; refrigerant pressure verification annually; drive belt and bearing assessment every 2,000 hours or per OEM service bulletin.
Does the unit support rotor auto-identification?
No—rotor-specific parameters must be manually selected from the front-panel menu to ensure correct RCF calculation and safety limits.
