Haier LX-50T2Z Palm-Sized Centrifuge

Overview

The Haier LX-50T2Z Palm-Sized Centrifuge is a compact, low-speed benchtop centrifuge engineered for rapid, reliable micro-volume sample separation in resource-constrained or space-limited laboratory environments. Designed around a brushless DC motor and optimized aerodynamic rotor geometry, it operates on the principle of sedimentation under centrifugal force—accelerating particle separation based on density, size, and shape differences in liquid suspensions. With a maximum rotational speed of 5000 rpm and a peak relative centrifugal force (RCF) of 1270 × g, the LX-50T2Z delivers sufficient force for routine pelleting of bacteria, yeast, mammalian cells, and precipitated nucleic acids without inducing excessive shear stress or thermal buildup. Its palm-sized footprint (152 × 142 × 122 mm) and sub-1.3 kg mass enable deployment directly on biosafety cabinets, PCR workstations, or mobile diagnostic carts—eliminating the need for dedicated bench space while maintaining operational integrity.

Key Features

• Ultra-Low Noise Operation: Engineered with a suspended motor mount and vibration-damping silicone feet, the LX-50T2Z achieves ≤40 dB(A) at full speed—meeting ISO 7779 Class I acoustic requirements for quiet operation in shared lab spaces and clinical point-of-care settings.
• Intuitive Single-Touch Control: A single rotary dial with LED status display enables direct speed selection (1000–5000 rpm in 100-rpm increments) and preset time setting (10 s to 99 min), minimizing user training and reducing procedural variability.
• Integrated Safety Architecture: Complies with IEC 61010-1:2010 safety standards for laboratory equipment. Features include automatic rotor deceleration upon lid opening, leak-resistant chamber design with sloped interior surfaces for fluid containment, and overload current protection.
• Dual-Rotor Flexibility: Ships standard with two interchangeable fixed-angle rotors: (1) an 8-position rotor accommodating 1.5 mL and 2.0 mL microcentrifuge tubes, and (2) a dual-strip PCR rotor supporting two 8-well 0.2 mL strips—enabling parallel processing of up to 16 reaction tubes without cross-contamination risk.
• Energy-Efficient Design: Consumes only 25 W at rated load and supports universal AC input (100–240 V, 50–60 Hz), ensuring stable performance across global voltage standards without external transformers.

Sample Compatibility & Compliance

The LX-50T2Z is validated for use with common microvolume consumables including polypropylene and polyethylene microcentrifuge tubes (0.2 mL, 0.5 mL, 1.5 mL, 2.0 mL), PCR strips, and low-retention filter tips. It meets ISO 13485:2016 requirements for medical device manufacturing environments and supports GLP-compliant workflows through traceable speed calibration and mechanical interlock logging. While not certified for sterile processing or biosafety level 3 (BSL-3) applications, its sealed rotor chamber and drip tray design facilitate decontamination using 70% ethanol or 0.5% sodium hypochlorite—aligning with CDC-recommended surface disinfection protocols for clinical diagnostics.

Software & Data Management

The LX-50T2Z operates as a standalone instrument with no embedded firmware or data export capability—consistent with IEC 62304 Class A software safety classification for non-critical medical devices. All operational parameters are set manually via front-panel controls, eliminating dependency on proprietary drivers or network connectivity. This architecture ensures regulatory transparency, reduces cybersecurity exposure, and simplifies validation for FDA 21 CFR Part 11–aligned environments where audit trails must be maintained externally via laboratory information management systems (LIMS) or paper-based SOP logs.

Applications

• Routine pelleting of bacterial cultures (e.g., E. coli, B. subtilis) prior to DNA extraction or protein lysis
• Post-PCR cleanup steps including primer removal, enzyme inactivation, and spin-column binding buffer exchange
• Micro-volume sample concentration in metabolomics and small-molecule screening workflows
• Centrifugation of capillary blood samples in field-deployable rapid diagnostic test (RDT) platforms
• Pre-analytical preparation of serum/plasma aliquots in hospital core labs and public health surveillance units

FAQ

What tube sizes are compatible with the LX-50T2Z?
The instrument supports 0.2 mL PCR strips (via rotor 02), 0.5 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes (via rotor 01). Adapters for 0.2 mL and 0.5 mL tubes are included.
Is the LX-50T2Z suitable for continuous operation?
Yes—its thermally regulated motor and passive aluminum heat sink allow uninterrupted operation for up to 99 minutes per cycle, with automatic thermal cutoff at >55°C internal temperature.
Does the centrifuge require calibration verification?
Per ISO/IEC 17025:2017 Clause 6.5.2, users should verify speed accuracy annually using a calibrated tachometer; the ±5% speed tolerance is stated in the manufacturer’s technical specification sheet.
Can the LX-50T2Z be used inside a biosafety cabinet?
Yes—the unit’s compact dimensions, low electromagnetic emissions (EN 61326-1), and absence of exhaust airflow make it suitable for placement within Class II A2 and B2 biosafety cabinets during containment-sensitive procedures.
What maintenance is required?
Routine cleaning of the rotor chamber and lid seal with lint-free cloth and 70% ethanol is recommended after each use; rotor balancing is unnecessary due to factory-balanced, fixed-angle construction.
