AnTing DL-5200 Low-Speed High-Capacity Benchtop Centrifuge

Overview

The AnTing DL-5200 is a robust, low-speed benchtop centrifuge engineered for high-volume sample processing in clinical laboratories, bioprocessing facilities, and industrial quality control environments. It operates on the principle of sedimentation-based separation under controlled gravitational force, utilizing horizontal (swinging-bucket) rotor geometry to achieve uniform pelleting of suspended particles in large-volume liquid samples. With a maximum rotational speed of 4500 rpm and a peak relative centrifugal force (RCF) of 5000 × g, the DL-5200 delivers consistent, reproducible separation performance across viscous or particulate-laden media—including whole blood, cell culture harvests, wastewater suspensions, and polymer emulsions—without inducing excessive shear stress that may compromise sample integrity. Its reinforced polymer chassis minimizes vibration transmission while maintaining structural rigidity during extended operation at rated capacity.

Key Features

• High-capacity horizontal rotor configuration supporting four 1000 mL centrifuge bottles simultaneously—optimized for batch processing of bulk biological or environmental samples.
• Precision-engineered electronic door interlock system ensuring automatic motor cutoff when lid is unlatched, compliant with IEC 61010-1 mechanical safety standards.
• Microprocessor-controlled timer with adjustable range from 0 to 99 minutes, enabling precise dwell-time control for standardized protocols.
• Low-noise, brushless DC drive motor delivering stable rotational output across the full speed range (0–4500 rpm), with minimal thermal drift over multi-hour runs.
• Integrated imbalance detection circuitry that halts operation if mass asymmetry exceeds ±5% tolerance between opposing buckets—preventing mechanical resonance and bearing wear.
• Front-panel LED display with intuitive rotary encoder interface for parameter entry and real-time status monitoring (speed, time remaining, RCF, error codes).

Sample Compatibility & Compliance

The DL-5200 accommodates standard ISO-compliant 1000 mL polypropylene or stainless-steel centrifuge bottles, as well as custom-sized containers up to Ø120 mm diameter × 220 mm height. It supports common laboratory separation workflows involving anticoagulated blood (e.g., plasma preparation per CLSI H20-A2), yeast/bacterial pellet harvesting, sludge dewatering trials, and polymer phase separation studies. The instrument’s electrical design conforms to IEC 61010-1 Edition 3 for measurement, control, and laboratory use. While not certified to GLP/GMP Annex 11 or FDA 21 CFR Part 11 out-of-the-box, its operational logs (via optional RS-232 or USB data export) can be integrated into validated systems meeting audit-trail requirements for regulated environments.

Software & Data Management

The DL-5200 operates as a standalone instrument without proprietary software dependency. All operational parameters are set and monitored locally via the front-panel interface. For traceability in regulated labs, optional serial communication (RS-232) enables integration with laboratory information management systems (LIMS) or SCADA platforms for remote start/stop commands, run logging, and fault reporting. Time-stamped event records—including start time, final speed, elapsed duration, and any triggered safety interrupts—are retained in non-volatile memory for post-run review. No cloud connectivity or firmware update capability is provided; all calibration and maintenance procedures follow manufacturer-recommended intervals documented in the English-language service manual.

Applications

• Clinical diagnostics: Separation of serum/plasma from whole blood specimens prior to immunoassay or clinical chemistry analysis.
• Biomanufacturing: Harvesting mammalian or microbial cells from fermentation broth at pilot scale before downstream filtration or lysis steps.
• Environmental testing: Concentration of suspended solids from municipal wastewater or surface water samples for gravimetric or microbiological analysis.
• Food & beverage QA: Clarification of juice extracts, dairy emulsions, or starch suspensions for viscosity or compositional testing.
• Academic research: Preliminary fractionation of tissue homogenates or plant extract supernatants where high g-force is unnecessary but volume throughput is critical.

FAQ

What rotor types are compatible with the DL-5200?
The DL-5200 is configured exclusively for horizontal (swinging-bucket) rotors. It accepts only the factory-supplied 4-position rotor assembly designed for 1000 mL bottles. Adapters for smaller tubes (e.g., 50 mL conical) are available as optional accessories but do not alter the maximum rated capacity.
Is the centrifuge suitable for continuous operation?
Yes—the motor and cooling system are rated for uninterrupted operation up to 8 hours at 4000 rpm or lower. At maximum speed (4500 rpm), duty cycle should not exceed 4 hours continuously to maintain thermal stability and bearing longevity.
Does the unit include rotor balancing tools?
No balance weights or calibration tools are included. Users must manually balance loads to within ±5 g per bucket pair using standard laboratory scales prior to each run.
Can the timer be bypassed for indefinite spinning?
No. The timer is mandatory and non-defeatable; the motor automatically stops when the preset time elapses. There is no “hold” or “infinite run” mode.
What maintenance schedule is recommended?
Rotor inspection every 500 runs or annually (whichever occurs first); lubrication of door hinge mechanism every 6 months; verification of electronic interlock function prior to each daily use. Full service by authorized technicians is advised every 2 years.
