Overview
The LUXIANGYI TD-4K Mini Benchtop Centrifuge is a compact, fixed-angle centrifuge engineered for rapid, low-volume sample processing in resource-constrained or high-throughput laboratory environments. Operating on the principle of sedimentation under radial acceleration, the TD-4K generates up to 900 × g of relative centrifugal force at its maximum rotational speed of 4,000 rpm—sufficient for efficient pelleting of mammalian cells, bacterial cultures, and nucleic acid precipitates from microcentrifuge tubes. Its palm-sized footprint (189 × 161 × 122 mm) and sub-1 kg net weight enable seamless integration onto crowded benchtops, biosafety cabinets, or mobile lab carts without compromising mechanical stability. The unit employs a brushless DC motor with integrated thermal protection and electromagnetic braking—eliminating carbon brush wear, reducing maintenance intervals, and ensuring long-term torque consistency across repeated start-stop cycles.
Key Features
- Ultra-quiet operation (<48 dB[A]) achieved via precision-balanced rotor assembly, vibration-damping housing, and optimized airflow design—suitable for open-lab or shared core facility use.
- Fixed-angle rotor accommodating six standard microtubes (1.5 mL, 0.5 mL, or 0.2 mL) simultaneously; no rotor interchange required for routine microsample workflows.
- Digital LED display with intuitive rotary encoder control for precise rpm/RCF setting and real-time run monitoring—including elapsed time and remaining time.
- Automatic lid interlock system prevents operation unless the rotor chamber is fully closed and latched, complying with IEC 61010-1 safety standards for laboratory equipment.
- Thermal management system maintains ambient rotor temperature during extended runs, minimizing heat-induced denaturation of thermolabile biomolecules.
- CE-marked power supply (AC 220 V, 50 Hz) with overvoltage and short-circuit protection; compatible with standard laboratory wall outlets in China and other 220–240 V regions.
Sample Compatibility & Compliance
The TD-4K supports common polypropylene and polyethylene microcentrifuge tubes (1.5 mL, 0.5 mL, 0.2 mL), including conical-bottom and snap-cap variants used in DNA/RNA extraction, protein purification, and ELISA plate preparation. It is routinely deployed in GLP-compliant QC labs for pre-analytical sample conditioning prior to HPLC, mass spectrometry, or enzymatic assays. While not certified for clinical diagnostics under ISO 13485, its mechanical performance aligns with ASTM F2119-22 guidelines for benchtop centrifuge verification. The device meets RoHS Directive 2011/65/EU for hazardous substance restriction and conforms to EMC Directive 2014/30/EU for electromagnetic compatibility.
Software & Data Management
The TD-4K operates as a standalone instrument without proprietary software dependency. All operational parameters are set and monitored locally via the front-panel interface. No data logging, USB export, or network connectivity is provided—consistent with its design intent as a dedicated, single-purpose microcentrifuge. For laboratories requiring audit trails, users may integrate external timers or digital lab notebooks (e.g., LabArchives, Benchling) to record run conditions per SOP. The absence of electronic data storage ensures full compliance with FDA 21 CFR Part 11 requirements where electronic records are not mandated for this class of equipment.
Applications
- Routine spin-down of PCR tubes prior to thermal cycling or sequencing library preparation.
- Microscale pelleting of E. coli, yeast, or mammalian suspension cultures (e.g., HEK293, CHO-K1) for downstream lysis or supernatant harvesting.
- Clarification of viscous lysates or column eluates in affinity purification workflows.
- Quick sedimentation of magnetic beads in automated nucleic acid isolation platforms.
- Centrifugation of capillary blood samples in point-of-care research settings where space and power availability are limited.
- Preparative steps in microfluidic assay development, including reagent loading and air bubble removal from microchannels.
FAQ
What is the maximum relative centrifugal force (RCF) achievable with the TD-4K?
The TD-4K delivers a maximum RCF of 900 × g at 4,000 rpm when using the standard 1.5 mL tube configuration.
Can the TD-4K accommodate 0.2 mL PCR strips?
Yes—the fixed-angle rotor accepts individual 0.2 mL tubes and is compatible with standard 8-tube PCR strips when loaded in pairs across the rotor positions.
Is the rotor autoclavable?
No—the rotor is constructed from high-strength aluminum alloy and is not designed for steam sterilization; wipe-down with 70% ethanol or isopropanol is recommended between uses.
Does the TD-4K support programmable run profiles or timer functions?
It features a manual timer adjustable from 1 second to 99 minutes and 59 seconds, but does not support multi-step or stored protocols.
What safety certifications does the TD-4K hold?
The unit carries CE marking and complies with IEC 61010-1:2010 for electrical safety in laboratory instruments, including mechanical stability, insulation resistance, and enclosure integrity testing.
