Overview
The AnTing TDL-40B is a benchtop low-speed centrifuge engineered for high-capacity batch separation of suspensions and emulsions in routine laboratory, quality control, and pilot-scale production environments. Operating on the principle of sedimentation under controlled gravitational force (RCF), the TDL-40B delivers reproducible separation performance across diverse sample types—including cell pellets, precipitated proteins, whole blood fractions, and industrial colloidal dispersions—without inducing excessive shear stress associated with high-speed operation. Its design prioritizes operational stability, mechanical robustness, and compliance-ready safety architecture, making it suitable for GLP-aligned workflows where traceability and operator protection are mandated.
Key Features
- Stable low-speed operation up to 5000 rpm with maximum relative centrifugal force of 4328 ×g—optimized for gentle yet effective pelleting of fragile biological aggregates and dense particulates.
- Swinging-bucket rotor configuration supporting multiple tube formats: four 100 mL conical tubes, eight 50 mL tubes, or sixteen 15 mL tubes—all validated at up to 4000 rpm for balanced load distribution and thermal uniformity.
- Reinforced polymer chassis integrated with vibration-damping base and precision-balanced drive shaft, ensuring <±1.5 mm/s vibration amplitude at full load and rated speed (per ISO 1940-1 G2.5 balance class).
- Microprocessor-controlled digital timer (0–99 minutes) with automatic brake deceleration and audible end-of-run alert—enabling unattended operation within defined safety parameters.
- Electronically interlocked lid mechanism that prevents rotor rotation unless fully latched and halts operation immediately upon lid opening—meeting IEC 61010-1:2010 safety requirements for laboratory equipment.
- Energy-efficient 400 W induction motor with thermal overload protection and sealed bearing assembly rated for ≥20,000 hours MTBF under continuous intermittent use.
Sample Compatibility & Compliance
The TDL-40B accommodates standard polypropylene, polycarbonate, and glass centrifuge tubes conforming to ISO 8573-1 Class 4 purity specifications. It supports common clinical and industrial protocols including ASTM D6978-05 (sediment analysis), USP (dissolution testing sample preparation), and ISO 13530:2017 (centrifuge performance verification). While not certified for biosafety level (BSL) containment, its sealed rotor chamber and drip-resistant housing meet IP21 ingress protection standards. Documentation includes factory calibration certificate (speed and timer accuracy ±1% full scale), electrical safety test report, and CE-marked conformity declaration per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).
Software & Data Management
The TDL-40B operates as a standalone instrument with no embedded software or network interface. All operational parameters—including set speed, time, and actual RCF—are displayed via dual LED readouts (rpm and minutes remaining). For regulated environments requiring audit trails, users may integrate external logging via analog voltage output (0–5 V proportional to rpm) or optional RS-232 serial module (available separately), enabling timestamped data capture into LIMS or ELN systems compliant with FDA 21 CFR Part 11 when paired with validated third-party acquisition software.
Applications
- Routine serum/plasma separation from whole blood in clinical labs and point-of-care settings.
- Clarification of fermentation broths and microbial culture harvests in bioprocessing development.
- Preparative isolation of extracellular vesicles, microvesicles, and apoptotic bodies using differential low-speed pre-clearing steps (e.g., prior to ultracentrifugation).
- Industrial quality control of paint, ink, and ceramic slurry stability through standardized settling rate assessment.
- Environmental sample processing—including soil suspension fractionation and wastewater solids recovery—under ISO 5667-14 protocols.
- Educational demonstrations of sedimentation kinetics and Stoke’s law validation in undergraduate physics and biochemistry laboratories.
FAQ
What is the maximum recommended operating speed for 100 mL tubes?
The TDL-40B is validated for 100 mL tube use at up to 4000 rpm; exceeding this speed may compromise tube integrity and rotor balance.
Does the centrifuge include rotor certification documentation?
Yes—each unit ships with a rotor-specific balancing certificate and angular velocity verification report traceable to NIM (National Institute of Metrology, China).
Can the TDL-40B be used for radioactive samples?
No—it lacks radiation shielding or decontamination-rated surfaces; use only with non-hazardous or chemically inert samples per manufacturer’s safety classification.
Is the electronic door lock compatible with access control systems?
No—the interlock is self-contained and non-integrated; it functions solely as a mechanical safety cutoff without external signal output.
What maintenance intervals are specified for the drive system?
Annual inspection of belt tension (if applicable), bearing lubrication status, and door latch actuation force is recommended; no scheduled motor servicing is required within first 5 years under typical lab usage (≤4 hrs/day).
