TD5A Desktop Low-Speed Centrifuge

Overview

The TD5A Desktop Low-Speed Centrifuge is an engineered solution for routine sedimentation and pelleting applications in life science laboratories where reproducible, gentle separation of biological macromolecules—such as cells, organelles, nuclei, and large protein complexes—is required. Operating on the principle of differential sedimentation under controlled gravitational force (×g), the TD5A delivers precise rotational control at speeds up to 5500 rpm and relative centrifugal forces up to 4800 ×g. Its design prioritizes operational safety, long-term mechanical stability, and ergonomic usability in high-throughput academic, clinical, and quality control environments. Unlike high-speed or ultracentrifuges, the TD5A is optimized for low-shear, high-capacity processing—making it particularly suitable for blood banking, tissue culture harvest, food microbiology sample preparation, and agricultural extract clarification.

Key Features

• Brushless AC frequency-controlled motor ensures maintenance-free operation, zero carbon dust emission, and acoustic noise below 65 dB(A) during full-load rotation.
• TFT true-color capacitive touchscreen interface displays real-time speed, time remaining, ×g value, temperature (if equipped with optional cooling module), and rotor-specific graphical identification—enabling intuitive protocol execution without cross-reference manuals.
• Structural integrity derived from a fully welded steel chassis and a 304 stainless-steel centrifuge chamber resistant to corrosion from common laboratory reagents and disinfectants.
• Electro-mechanical door lock with automatic engagement/disengagement prevents accidental lid opening during operation and complies with IEC 61010-2-020 safety standards for centrifugal equipment.
• Multi-stage vibration damping system with passive auto-balancing capability minimizes floor transmission and extends bearing service life—even under partial load or minor tube weight asymmetry.
• Programmable acceleration/deceleration profiles (10 preset ramp rates) reduce sample disturbance during spin-up and braking, critical for fragile cell pellets or viscous biological suspensions.
• 20 non-volatile memory slots retain user-defined protocols—including speed, time, brake mode, and rotor selection—with automatic recall of last-used settings at power-on.

Sample Compatibility & Compliance

The TD5A supports universal compatibility across standard laboratory consumables via interchangeable rotors: horizontal swing-out rotors (e.g., 4 × 250 mL, 4 × 100 mL, 2 × 96-well microplate carriers), fixed-angle rotors (12 × 10 mL), and adapter-based configurations for 0.2–50 mL tubes including vacuum blood collection tubes. All rotors are dynamically balanced and certified for continuous operation at rated speeds per ISO 15797:2021. The instrument meets electromagnetic compatibility requirements per EN 61326-1 and electrical safety per EN 61010-1. While the base model is air-cooled, optional refrigerated variants (not included) may support GLP-compliant cold-chain workflows aligned with USP analytical instrument qualification guidelines.

Software & Data Management

The TD5A operates autonomously without external PC dependency; however, its embedded firmware supports audit-ready event logging—including start/stop timestamps, rotor ID, final speed, actual run time, and error codes—stored internally for ≥10,000 cycles. Optional RS-232 or USB-to-serial interfaces enable integration into LIMS or ELN systems for automated data capture. Though not FDA 21 CFR Part 11 compliant out-of-the-box, the device’s deterministic behavior, non-editable runtime logs, and password-protected parameter modification align with foundational ALCOA+ principles for data integrity in regulated QC labs.

Applications

• Blood component separation (RBC, WBC, platelet-rich plasma) in clinical diagnostics and transfusion medicine.
• Harvesting mammalian and insect cells post-adherent or suspension culture.
• Pelleting chloroplasts, mitochondria, and nuclei for subcellular fractionation studies.
• Sedimentation of foodborne pathogens (e.g., Salmonella, E. coli) from enrichment broths in food safety testing.
• Clarification of plant extracts, fermentation broths, and colloidal suspensions in agricultural R&D.
• Preparative centrifugation of ELISA plates prior to optical density reading.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the TD5A using the 4 × 250 mL rotor?
The maximum RCF is 3290 ×g at 4000 rpm with the 4 × 250 mL horizontal rotor.
Is the TD5A compatible with refrigerated operation?
The standard TD5A is air-cooled and non-refrigerated. A separate refrigerated variant (TD5AR) is available upon request with temperature range –20 °C to +40 °C.
Does the instrument support rotor auto-recognition?
Yes—the touchscreen displays a labeled image of the installed rotor and validates its maximum rated speed before initiating rotation.
Can the TD5A be integrated into a laboratory information management system (LIMS)?
Via optional serial communication modules (RS-232 or USB-CDC), raw run logs and status signals can be exported for middleware ingestion.
What safety certifications does the TD5A hold?
It conforms to IEC 61010-1 (Safety Requirements for Electrical Equipment), IEC 61010-2-020 (Particular Requirements for Centrifuges), and EN 61326-1 (EMC for Laboratory Use).
