Overview
The AnTing DL-5000B-C is a benchtop low-speed refrigerated centrifuge engineered for routine separation tasks in clinical laboratories, quality control environments, and academic research settings where temperature-sensitive biological samples—such as whole blood, serum, plasma, cell suspensions, and crude tissue homogenates—require gentle yet reliable sedimentation. Operating on the principle of differential sedimentation under controlled gravitational force (RCF), the instrument delivers consistent performance at speeds up to 5000 rpm and a maximum relative centrifugal force of approximately 4000 ×g. Its integrated refrigeration system maintains sample integrity across a wide operational temperature range (−20 °C to +30 °C), while the precision-machined horizontal rotor assembly ensures mechanical stability and rotational balance—even during extended runs. Designed with structural rigidity and acoustic dampening in mind, the unit complies with ISO 13485-aligned manufacturing practices and meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 for laboratory equipment.
Key Features
- Refrigerated operation with independent compressor-based cooling system, enabling precise thermal management during prolonged centrifugation cycles
- Microprocessor-controlled speed regulation with digital display and real-time RPM/RCF conversion
- Electronic safety door lock with automatic rotor recognition and imbalance detection
- Horizontal swing-out rotor configuration compatible with multiple tube formats—including 100 mL × 4, 250 mL × 4, 15 mL × 16, and specialized 6 mL × 96 radioimmunoassay (RIA) plates
- Stainless steel chamber and rotor housing for corrosion resistance and ease of decontamination
- Low-noise design (<70 dB[A]) achieved through optimized motor mounting and vibration-damping chassis
- Programmable timer (0–99 minutes) with auto-brake and hold-at-end functionality
Sample Compatibility & Compliance
The DL-5000B-C accommodates standard polypropylene, polycarbonate, and glass centrifuge tubes ranging from 5 mL to 250 mL, supporting both fixed-angle and horizontal rotor configurations via interchangeable rotor carriers. It is routinely employed in applications governed by CLSI GP44-A4 (centrifuge validation), USP <711>, and ISO 15189:2022 requirements for pre-analytical sample processing. While not certified for GLP or GMP environments out-of-the-box, its audit-ready operational logs (via optional data export interface), traceable temperature control, and mechanical interlock system support integration into regulated workflows compliant with FDA 21 CFR Part 11 when paired with validated software extensions.
Software & Data Management
The centrifuge operates via an embedded microcontroller with no external PC dependency; however, it supports RS-232 serial output for connection to laboratory information systems (LIS) or centralized monitoring platforms. Optional firmware upgrades enable timestamped run logging—including start/stop time, set parameters (speed, temperature, duration), and fault codes—for internal QA documentation. All parameter changes are recorded with user ID fields (when integrated with networked authentication), satisfying basic ALCOA+ principles for data integrity in non-GxP contexts. No proprietary cloud service or subscription model is required for core functionality.
Applications
- Preparation of serum and plasma from whole blood specimens in clinical diagnostics
- Sedimentation of mammalian and microbial cells prior to lysis or cryopreservation
- Clarification of culture supernatants and crude protein extracts
- Isolation of extracellular vesicles and lipoprotein fractions using density-gradient-compatible rotors
- Radioimmunoassay (RIA) plate processing with high-throughput 6 mL × 96 rotor configuration
- Quality assurance testing of colloidal suspensions and emulsions in pharmaceutical formulation labs
FAQ
What is the minimum operating temperature of the DL-5000B-C?
The unit achieves a stable chamber temperature of −20 °C under ambient conditions ≤25 °C and standard load conditions.
Does this centrifuge support rotor calibration verification?
Yes—rotor identification is performed automatically upon insertion; users may perform manual RCF verification using NIST-traceable tachometers and thermistors per ISO 21501-4 guidelines.
Can the DL-5000B-C be used for regulatory-compliant sample preparation?
It meets foundational requirements for sample integrity and reproducibility; full GxP compliance requires documented IQ/OQ/PQ protocols and integration with validated electronic record systems.
Is the refrigeration system maintenance-free?
The sealed compressor system requires no routine oil changes but benefits from annual condenser coil cleaning and refrigerant pressure checks per manufacturer service recommendations.
Are spare rotors and adapters available internationally?
Original-equipment horizontal rotors, RIA plates, and tube adapters are distributed globally through authorized AnTing technical partners and comply with CE marking and RoHS Directive 2011/65/EU.
