Overview
The AnTing Feige TDL-5-A is a benchtop low-speed centrifuge engineered for high-capacity, routine separation of biological suspensions under controlled rotational conditions. Operating on the principle of sedimentation-based separation—where differential particle migration occurs under applied centrifugal force—the TDL-5-A delivers consistent RCF (Relative Centrifugal Force) up to 5000 ×g at a maximum rotational speed of 5000 rpm. Its robust mechanical architecture, coupled with a brushless DC motor and microprocessor-based speed/RCF/timer control system, ensures stable operation across extended run cycles. Designed specifically for applications requiring large-volume processing without thermal stress or excessive noise generation, the unit maintains minimal temperature rise within the centrifuge chamber during operation—a critical factor when handling thermolabile samples such as plasma, whole blood, cell cultures, or crude enzyme extracts.
Key Features
- Benchtop footprint optimized for space-constrained laboratory environments (460 × 510 × 680 mm), with a total mass of 40 kg ensuring operational stability.
- Digital LED display with intuitive keypad interface enables precise setting and real-time monitoring of speed (rpm), RCF (×g), and countdown timer (0–99 min).
- Electronically interlocked safety door prevents rotor rotation unless fully latched; automatic rotor deceleration and brake engagement upon lid opening comply with IEC 61010-2-020 safety standards.
- Horizontal swinging-bucket rotor design accommodates multiple tube formats simultaneously—enabling parallel processing of heterogeneous sample sets without cross-contamination risk.
- Low-noise operation (<65 dB(A) at 5000 rpm) achieved via precision-balanced rotor assembly and vibration-dampening base mount—critical for shared lab spaces and long-duration protocols.
- Thermally insulated centrifuge chamber minimizes ambient heat transfer, limiting internal temperature rise to <3°C over 30-minute continuous operation at max speed.
Sample Compatibility & Compliance
The TDL-5-A supports a broad range of standard laboratory consumables, including polypropylene conical tubes (10–250 mL), glass centrifuge tubes (up to 50 mL), and specialized assay plates (e.g., 96-well RIA trays and 192-well enzymatic reaction plates). Its horizontal rotor configuration allows uniform pelleting of particulates across all tube positions, making it suitable for blood fractionation (plasma/serum isolation), yeast/bacterial cell harvesting, precipitate recovery from protein purification workflows, and environmental sample clarification (e.g., wastewater sludge or soil extracts). The device meets essential electrical safety requirements per IEC 61010-1 and is routinely deployed in facilities adhering to ISO/IEC 17025, CLIA, and GLP frameworks. While not certified for sterile processing or BSL-2 containment use, its cleanable stainless-steel chamber and removable rotor carriers facilitate routine decontamination per institutional SOPs.
Software & Data Management
The TDL-5-A operates via embedded firmware with no external software dependency. All operational parameters—including speed, RCF, time, and rotor identification—are stored in non-volatile memory and recalled across power cycles. The system logs last-run settings and displays cumulative runtime hours for preventive maintenance scheduling. Though lacking network connectivity or FDA 21 CFR Part 11-compliant audit trails, its deterministic control logic and physical key-lock function support traceable manual operation in regulated environments where electronic records are maintained externally (e.g., via LIMS-integrated logbooks or paper-based batch records).
Applications
- Clinical diagnostics: Plasma separation from whole blood (EDTA/heparinized specimens) prior to ELISA, immunoassay, or coagulation testing.
- Biopharmaceutical QC: Clarification of fermentation broths and harvest of microbial biomass for downstream analysis.
- Food & beverage testing: Sediment analysis in juice concentrates, dairy emulsions, and brewing wort.
- Environmental monitoring: Solid-liquid separation of suspended solids from aqueous effluents or soil leachates.
- Academic research: Routine pelleting of mammalian cells, plant protoplasts, or subcellular organelles prior to lysis or density gradient preparation.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the TDL-5-A?
The TDL-5-A achieves a maximum RCF of 5000 ×g at 5000 rpm with the 250 mL horizontal rotor.
Can the TDL-5-A accommodate microplate carriers for high-throughput assays?
Yes—optional 96-well RIA rotors and 192-well enzymatic plate carriers are available as accessories, operating at 5000 rpm (5000 ×g) and 3500 rpm (1500 ×g), respectively.
Is the centrifuge compatible with refrigerated operation?
No—the TDL-5-A is a non-refrigerated model; users requiring temperature control must employ pre-chilled samples and ambient-conditioned lab environments.
Does the unit include rotor imbalance detection?
The system incorporates mechanical imbalance sensing that halts acceleration if significant load asymmetry is detected during spin-up, preventing damage to bearings or drive components.
What maintenance intervals are recommended for routine use?
Rotor inspection and chamber cleaning should occur after every 200 runs or monthly—whichever comes first—while bearing lubrication and calibration verification are advised annually by qualified service personnel.
