TDL-50A Digital Display Electric Centrifuge

Overview

The TDL-50A Digital Display Electric Centrifuge is a general-purpose, benchtop centrifuge engineered for reliable sedimentation-based separation in routine laboratory workflows. It operates on the principle of radial acceleration—generating centrifugal force through high-speed rotation of sample containers—to accelerate phase separation of heterogeneous mixtures based on density differentials. Designed for consistent performance in clinical, biochemical, and chemical laboratories, the unit delivers precise control over rotational parameters without requiring refrigeration or vacuum systems. Its mechanical architecture prioritizes operational stability: the motor-driven rotor assembly incorporates dynamic balancing mechanisms to minimize vibration during acceleration and deceleration cycles, ensuring long-term bearing integrity and reducing mechanical fatigue across repeated daily use.

Key Features

• Stepless variable-speed control with real-time digital RPM readout enables fine-tuned optimization of separation kinetics for diverse sample viscosities and particle sizes.
• Integrated timer (0–60 minutes) with automatic shut-off function supports unattended operation while maintaining protocol compliance and sample integrity.
• Aluminum alloy rotor base with stainless steel protective sleeves provides corrosion resistance and mechanical protection for standard 50 mL conical centrifuge tubes, minimizing tube deformation or rupture under sustained RCF loads.
• Low-noise design (≤60 dB[A] at 1 m distance) ensures compatibility with shared lab environments where acoustic emissions must remain within occupational safety thresholds per ISO 11201.
• Thermally optimized motor housing and airflow path reduce operational temperature rise, contributing to extended component lifespan and stable rotational accuracy over extended run times.
• Compact footprint and lightweight construction facilitate flexible placement on standard lab benches or mobile carts without structural reinforcement requirements.

Sample Compatibility & Compliance

The TDL-50A accommodates up to six 50 mL polypropylene or glass centrifuge tubes arranged symmetrically in its fixed-angle rotor configuration. It is validated for use with aqueous buffers, serum, plasma, cell lysates, precipitated proteins, and immunological reagents commonly handled in CLIA-certified clinical labs and ISO/IEC 17025-accredited testing facilities. While not certified for biosafety level 3 (BSL-3) containment or aerosol-tight operation, it meets basic electrical safety requirements per GB 4793.1–2007 (equivalent to IEC 61010-1) and electromagnetic compatibility standards per GB/T 18268.1–2010. Users performing regulated analyses (e.g., USP , CLSI EP17-A2) are advised to perform periodic speed calibration using traceable tachometry and document rotor maintenance per internal SOPs.

Software & Data Management

As a standalone analog-digital hybrid instrument, the TDL-50A does not feature embedded software, network connectivity, or electronic data logging capabilities. All operational parameters—including set speed, elapsed time, and final RCF—are manually configured via front-panel controls and displayed on an integrated LED screen. For laboratories operating under FDA 21 CFR Part 11 or GLP/GMP frameworks, manual entry of run parameters into laboratory notebooks or LIMS remains the recommended practice. Optional external tachometers or digital timers may be employed to support audit-ready recordkeeping when required by quality assurance protocols.

Applications

• Routine serum/plasma separation from whole blood specimens in hospital core labs and point-of-care testing units.
• Clarification of crude enzymatic digests or antibody-containing supernatants prior to ELISA, Western blotting, or chromatographic analysis.
• Sedimentation of particulate matter in environmental water samples during preliminary filtration-free screening.
• Isolation of precipitated nucleic acid complexes following alcohol-based extraction protocols.
• Removal of insoluble aggregates from protein formulation buffers during early-stage biopharmaceutical development.
• Preparative concentration of colloidal suspensions in materials science education labs.

FAQ

Does the TDL-50A support refrigerated operation?
No. This model is air-cooled and designed for ambient-temperature centrifugation only.
Can I use this centrifuge for radioactive or hazardous samples?
Not without additional engineering controls. The unit lacks sealed rotor chambers or secondary containment features required for such applications.
Is rotor imbalance detection built into the system?
It includes passive mechanical balancing but no active imbalance-sensing circuitry or automatic shutdown logic.
What maintenance intervals are recommended?
Inspect rotor sleeves and drive shaft coupling every 200 operating hours; lubricate motor bearings annually per manufacturer guidelines.
Is speed calibration traceable to national standards?
Calibration requires external NIST-traceable tachometry; no factory-issued certificate is included with standard delivery.
