AnTing TDL-80-2C Benchtop Low-Speed Centrifuge

Overview

The AnTing TDL-80-2C is a robust, benchtop low-speed centrifuge engineered for routine separation tasks in academic laboratories, quality control environments, and small-scale production facilities. Operating on the principle of sedimentation under centrifugal force, it accelerates phase separation of heterogeneous mixtures—including cell suspensions, precipitated proteins, blood components, and particulate-laden solutions—by generating controlled radial acceleration up to 2625 × g at its maximum rotational speed of 4000 rpm. Designed for operational simplicity and mechanical reliability, the unit features a fixed-angle rotor configuration optimized for rapid pelleting of standard 15 mL conical tubes (e.g., Falcon-type), making it particularly suitable for applications where high-throughput sample processing is required without demanding ultracentrifugal forces.

Key Features

• Fixed-angle rotor accommodating twelve 15 mL centrifuge tubes—compatible with widely used polypropylene conical tubes meeting ISO 8573-1 and ASTM D4172 dimensional tolerances.
• Digitally adjustable timer with precise 1-minute resolution across a 0–99 minute range, supporting both timed runs and continuous operation modes.
• Electronically interlocked safety lid that prevents rotor activation unless fully closed and latched—compliant with IEC 61010-1:2010 requirements for laboratory electrical equipment safety.
• Reinforced polymer chassis providing structural rigidity while minimizing overall mass (45 kg), facilitating stable placement on standard laboratory benches without anchoring.
• Brushless DC motor delivering consistent torque output across the full speed range (0–4000 rpm), ensuring low vibration, minimal heat generation, and extended service life.
• Integrated thermal protection circuitry and over-speed detection system to safeguard against mechanical failure during extended or unattended operation.

Sample Compatibility & Compliance

The TDL-80-2C supports standard 15 mL centrifuge tubes manufactured from polypropylene (PP) or polycarbonate (PC), including those certified for use in GLP-compliant workflows. Its rotor geometry maintains tube orientation within ±0.5° tolerance during rotation, preserving pellet integrity and reproducibility across repeated runs. While not classified as a Class II biosafety device, the unit’s sealed rotor chamber and non-porous housing surface allow for effective decontamination using 70% ethanol or sodium hypochlorite solutions—facilitating adherence to ISO 15189 pre-analytical handling guidelines. The instrument meets CE marking requirements under the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility Directive (2014/30/EU).

Software & Data Management

The TDL-80-2C operates via an embedded microcontroller-based interface with no external software dependency. All operational parameters—including speed setpoint, time duration, and run status—are displayed on a dual-digit LED panel with tactile push-button controls. Though lacking USB or Ethernet connectivity, the device supports manual logbook documentation aligned with FDA 21 CFR Part 11 principles when paired with institutional SOPs governing instrument usage records. Audit trails may be maintained through dated, signed paper logs or integrated LIMS entries referencing batch-specific run identifiers.

Applications

• Routine pelleting of mammalian cells (e.g., HEK293, CHO) prior to lysis or media exchange.
• Sedimentation of erythrocytes and leukocyte isolation from whole blood samples in clinical screening labs.
• Clarification of bacterial culture supernatants following overnight growth in LB or TB media.
• Removal of insoluble aggregates from antibody or recombinant protein preparations before filtration or chromatography.
• Phase separation in solvent extraction protocols involving aqueous-organic biphasic systems (e.g., phenol-chloroform DNA isolation).
• Preparative centrifugation of latex microspheres or silica nanoparticles for size-based fractionation studies.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with this centrifuge?

The TDL-80-2C delivers a maximum RCF of 2625 × g at 4000 rpm with the standard 15 mL fixed-angle rotor.
Is the rotor autoclavable?

No—the fixed-angle rotor is constructed from aluminum alloy with anodized surface treatment and is not designed for autoclaving; cleaning should be performed with isopropyl alcohol or mild detergent solutions.
Does the unit support variable acceleration/deceleration rates?

No—it features fixed ramp profiles optimized for gentle deceleration to minimize resuspension of pellets; no programmable acceleration/deceleration settings are available.
Can this centrifuge be used for clinical diagnostics under CLIA or CAP requirements?

Yes—provided that the instrument is included in the laboratory’s equipment qualification protocol (IQ/OQ/PQ) and operated per documented SOPs, it fulfills functional requirements for specimen preparation in waived and moderate-complexity testing categories.
What maintenance schedule is recommended?

Visual inspection of rotor integrity and lid interlock function should occur before each use; full preventive maintenance—including bearing lubrication and motor calibration—is advised every 12 months or after 1000 operating hours, whichever occurs first.
