Overview
The AnTing Feige TDL-40B is a microprocessor-controlled benchtop centrifuge engineered for routine separation of biological suspensions at low rotational speeds and high sample volumes. It operates on the principle of sedimentation under centrifugal force—applying controlled radial acceleration to separate particles based on density, size, and shape within heterogeneous liquid mixtures. Designed for stability and reproducibility in non-ultracentrifugal applications, the TDL-40B delivers consistent RCF (Relative Centrifugal Force) up to 2770 ×g at 4000 rpm, making it suitable for primary isolation steps in clinical, pharmaceutical, food safety, and environmental laboratories. Its robust cast-aluminum housing, balanced rotor assembly, and precision-machined horizontal swing-out rotor ensure mechanical integrity across extended duty cycles. Unlike floor-standing units, its compact footprint allows integration into standard laboratory workbenches without compromising structural rigidity or thermal management.
Key Features
- Microprocessor-based digital control system with LED display for real-time monitoring of speed, time, and remaining runtime
- Horizontal swing-out rotor configuration supporting multiple tube formats: 100 mL × 4, 50 mL × 8, or 20 mL × 16 per run
- Electronic door interlock mechanism ensuring automatic motor shutdown when lid is opened mid-run
- Low-noise brushless motor drive minimizing acoustic emission during operation (≤65 dB(A) at 1 m)
- Thermally optimized chamber design limiting internal temperature rise to <3 °C above ambient over 30-minute continuous operation
- Adjustable timer range from 0 to 99 minutes with auto-stop functionality and audible end-of-run signal
- Stainless-steel rotor chamber and corrosion-resistant aluminum housing for long-term chemical compatibility and cleanability
Sample Compatibility & Compliance
The TDL-40B accommodates standard polypropylene, polycarbonate, and glass centrifuge tubes conforming to ISO 8573-1 (clean compressed air classification) and ASTM D4169 performance testing protocols for container integrity. It supports common biospecimen processing workflows including plasma/serum separation from whole blood (per CLSI H3-A6 guidelines), cell pellet harvesting from suspension cultures, and clarification of fermentation broths or food extracts. While not certified for GLP/GMP production environments, its electronic log capability (via optional RS232 interface) enables basic audit trail generation compliant with FDA 21 CFR Part 11 Annex 11 principles when integrated into validated laboratory information management systems (LIMS). All electrical components meet IEC 61010-1 safety standards for laboratory equipment.
Software & Data Management
The TDL-40B features embedded firmware with no external software dependency. All operational parameters—including set speed, elapsed time, remaining time, and error codes—are displayed and stored locally in non-volatile memory for up to 100 recent runs. Optional serial communication (RS232) permits connection to external PCs for manual data export or integration into centralized instrument monitoring platforms. Though lacking native cloud synchronization or multi-user role management, its deterministic behavior and deterministic start/stop timing support traceable method execution in regulated settings where procedural consistency outweighs advanced analytics.
Applications
- Clinical diagnostics: Separation of serum, plasma, and buffy coat layers from anticoagulated whole blood specimens
- Pharmaceutical QC: Clarification of protein solutions, vaccine suspensions, and excipient blends prior to filtration or lyophilization
- Food microbiology: Pellet recovery of bacteria, yeasts, and spores from enrichment broths and rinse waters
- Environmental testing: Concentration of particulate matter, algae, or protozoa from water samples per EPA Method 1623
- Academic research: Preliminary fractionation of subcellular organelles, extracellular vesicles, and polymerized biopolymers under mild g-force conditions
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the TDL-40B?
The TDL-40B achieves a maximum RCF of 2770 ×g at its top speed of 4000 rpm with the 100 mL horizontal rotor.
Can this centrifuge be used for blood bank applications requiring precise temperature control?
No—the TDL-40B is a non-refrigerated unit and does not provide active temperature regulation; it is intended for ambient-temperature separations only.
Is rotor balancing required before each run?
Yes—symmetrical loading of opposing buckets is mandatory to maintain mechanical balance and prevent vibration-induced wear or failure.
Does the TDL-40B comply with international electromagnetic compatibility (EMC) standards?
Yes—it meets IEC 61326-1 for electromagnetic immunity and emissions in laboratory environments.
What maintenance intervals are recommended for optimal longevity?
Visual inspection of rotor integrity and door latch function should occur before each use; full preventive maintenance—including bearing lubrication and firmware verification—is advised every 12 months or after 500 operating hours, whichever comes first.
