Overview
The AnTing TDL-5-A Automatic Lid-Release Benchtop Centrifuge is a microprocessor-controlled, low-speed horizontal centrifuge engineered for routine separation tasks in clinical diagnostics, biotechnology laboratories, and quality control environments. It operates on the principle of sedimentation under centrifugal force—accelerating particle settling based on density, size, and shape differences within heterogeneous liquid samples. Designed for ambient-temperature operation (non-refrigerated), the TDL-5-A delivers consistent performance for applications requiring gentle yet effective phase separation, including blood serum/plasma preparation, cell pellet recovery, and suspension clarification. Its automatic lid-release mechanism eliminates manual unlocking steps post-run, reducing operator intervention and supporting workflow efficiency in high-throughput settings. The unit features a robust reinforced polymer chassis, vibration-damping base design, and precision-machined horizontal rotor assembly to ensure mechanical stability and long-term rotational accuracy.
Key Features
- Microprocessor-based speed and time control with digital display for repeatable parameter recall
- Automatic lid release system activated upon complete deceleration—compliant with ISO 13485-aligned safety protocols for medical device labs
- Horizontal (swinging-bucket) rotor configuration enabling uniform tube orientation during acceleration and deceleration
- Electronic lid interlock prevents operation when the lid is unlatched or improperly sealed—meeting IEC 61010-1 safety requirements
- Low-noise operation (<70 dB[A]) achieved via balanced rotor dynamics and acoustic enclosure design
- Energy-efficient brushless DC motor with variable-frequency drive for smooth acceleration/deceleration profiles
- Non-refrigerated architecture—optimized for ambient lab conditions; no compressor, refrigerant, or condensate management required
Sample Compatibility & Compliance
The TDL-5-A accommodates standard polypropylene or glass test tubes up to 5 mL volume across 32 positions in its fixed-angle-compatible horizontal rotor. Tube compatibility includes common formats such as 13 × 100 mm, 16 × 100 mm, and 16 × 125 mm dimensions. It supports centrifugation of whole blood, urine sediments, bacterial cultures, and polymer emulsions where thermal sensitivity is not a limiting factor. While not certified for GLP/GMP-regulated environments out-of-the-box, the instrument’s electronic logging capability (via optional RS232 interface) permits integration into validated workflows adhering to FDA 21 CFR Part 11 when paired with compliant LIMS software. All electrical and mechanical safety certifications conform to CE marking directives and GB/T 19001–2016 (equivalent to ISO 9001:2015).
Software & Data Management
The TDL-5-A features embedded firmware with non-volatile memory capable of storing up to 10 user-defined protocols—including speed, time, and ramp profiles. Though it does not include proprietary PC software, its RS232 serial port enables connection to external data acquisition systems for audit-trail generation, remote start/stop commands, and real-time RPM/RCF monitoring. When integrated into laboratory information systems (LIS), the device supports traceability requirements for ISO/IEC 17025-accredited testing laboratories. Firmware updates are performed via manufacturer-provided utility tools; version history and calibration logs can be exported for internal QA documentation.
Applications
- Routine serum and plasma separation from whole blood specimens in clinical chemistry and hematology labs
- Pelleting of mammalian and microbial cells prior to lysis or cryopreservation
- Clarification of crude enzyme extracts, antibody supernatants, and colloidal suspensions
- Preparative separation of particulates in environmental water samples (e.g., algae, silt)
- Quality assurance testing of pharmaceutical suspensions and topical formulations
- Educational use in undergraduate biology and biochemistry teaching laboratories
FAQ
Is the TDL-5-A suitable for centrifuging temperature-sensitive biological samples?
No—it is a non-refrigerated centrifuge intended for ambient-temperature operation only. For heat-labile samples requiring thermal control, a refrigerated benchtop model with active cooling (e.g., −20 °C to +40 °C range) is recommended.
Can the rotor accommodate tubes larger than 5 mL?
The standard horizontal rotor is mechanically optimized for 5 mL tubes. Using oversized tubes may compromise balance, increase vibration, and void warranty coverage.
Does the automatic lid-release function require maintenance or periodic calibration?
The electromechanical actuator is sealed and maintenance-free under normal operating conditions. However, annual verification of lid interlock timing and torque response is advised per laboratory preventive maintenance schedules.
Is the TDL-5-A compliant with international electromagnetic compatibility (EMC) standards?
Yes—the unit meets EN 61326-1:2013 for laboratory equipment and EN 55011:2016 Class B emission limits, ensuring safe co-location with sensitive analytical instrumentation.
What documentation is provided for regulatory submissions?
Standard delivery includes Declaration of Conformity (CE), electrical safety test report, user manual, and rotor balancing certificate. Customized IQ/OQ documentation packages are available upon request for regulated environments.
