Overview
The AnTing TDL-60B is a robust, benchtop low-speed centrifuge engineered for routine separation tasks in clinical, academic, and industrial quality control laboratories. It operates on the principle of sedimentation under centrifugal force—accelerating phase separation of heterogeneous mixtures based on particle density, size, and medium viscosity. With a maximum rotational speed of 6000 rpm and a peak relative centrifugal force (RCF) of 5200 × g, the TDL-60B delivers consistent performance for applications requiring gentle yet effective pelleting of cells, precipitates, or suspended particulates without inducing shear-induced damage typical of high-speed or ultracentrifugation. Its compact footprint (350 × 390 × 350 mm) and 20 kg net weight ensure stable operation on standard laboratory countertops while maintaining mechanical rigidity during extended runs.
Key Features
- Stable, low-vibration operation enabled by precision-balanced rotor assembly and reinforced polymer housing
- Electronic door interlock system that automatically halts rotation when the lid is opened—complying with IEC 61010-1 safety requirements for laboratory equipment
- Digital timer with adjustable range from 0 to 99 minutes, supporting both timed and continuous modes
- Swinging-bucket rotor as standard configuration—optimized for uniform sedimentation across all 12 positions with 20 mL tubes (e.g., polypropylene conical tubes or glass centrifuge tubes)
- Brushless DC motor providing high torque at low speeds, enhanced energy efficiency, and extended service life versus traditional brushed motors
- Thermal management system prevents excessive heat buildup during prolonged operation, preserving sample integrity
- Front-panel LED display showing real-time rpm, RCF, remaining time, and error codes (e.g., imbalance detection, lid-open fault)
Sample Compatibility & Compliance
The TDL-60B accommodates standard 10–20 mL centrifuge tubes (diameter ≤17 mm), including common formats such as Falcon™-style conical tubes and borosilicate glass tubes. It supports balanced loading configurations only—users must ensure symmetrical mass distribution across opposing buckets to prevent rotor wobble and premature bearing wear. While not certified for biosafety level (BSL)-3 containment or aerosol-tight operation, the unit meets general-purpose safety standards applicable to non-hazardous sample processing under ISO/IEC 17025-aligned environments. Its design facilitates routine cleaning and decontamination using ethanol or 70% isopropanol—compatible with most GLP and internal QA protocols.
Software & Data Management
The TDL-60B is a standalone instrument without embedded software or network connectivity. All operational parameters are set manually via front-panel controls; no data logging, USB export, or PC interface is provided. This architecture aligns with laboratories prioritizing simplicity, audit-trail minimalism, and reduced validation overhead—particularly in regulated settings where electronic records are not required for basic centrifugation steps (e.g., pre-filtration clarification prior to HPLC injection). For users requiring traceability, manual logbook entries—including date/time, rotor ID, speed, duration, and operator initials—are recommended per internal SOPs.
Applications
- Preparative sedimentation of mammalian blood components (e.g., platelet-rich plasma isolation at 2500–3500 × g)
- Clarification of bacterial culture supernatants prior to protein purification or ELISA assay setup
- Separation of precipitated reagents (e.g., ammonium sulfate cuts, antibody complexes) in immunochemistry workflows
- Routine pelleting of yeast or E. coli cells in molecular biology labs (typically 3000–4500 × g, 5–15 min)
- Processing of environmental water samples for suspended solids analysis (e.g., ASTM D5907 for total suspended solids)
- Industrial QC tasks including pigment dispersion settling tests and emulsion stability assessment
FAQ
What rotor types are compatible with the TDL-60B?
Only the factory-supplied swinging-bucket rotor (12-position, 20 mL capacity) is validated for use. Adapters for smaller tubes (e.g., 15 mL or 5 mL) may be installed, but maximum load limits must be recalculated to maintain balance and avoid exceeding 5200 × g.
Does the TDL-60B support refrigeration?
No. This is a non-refrigerated centrifuge. Samples requiring temperature control must be pre-chilled and processed within ambient lab conditions (15–30 °C recommended).
Is the unit compliant with FDA 21 CFR Part 11?
Not applicable—no electronic records or digital signatures are generated. Compliance with Part 11 is not required for manual, non-auditable instruments used in non-critical unit operations.
Can this centrifuge be used for clinical diagnostics?
Yes—provided local regulatory requirements (e.g., CLIA, CAP, or ISO 15189) permit manual, non-validated centrifugation steps in specimen preparation workflows.
What maintenance is required?
Monthly visual inspection of rotor threads and bucket hinges; biannual cleaning of air vents and motor housing; annual calibration verification of speed and timer accuracy using an external tachometer and stopwatch—per manufacturer-recommended intervals.
