Overview
The VWR LX-120T2Z is a compact, high-performance benchtop centrifuge engineered for precision microcentrifugation in space-constrained laboratory environments. Designed around a brushless DC motor with floating suspension damping architecture, it delivers stable rotational dynamics and minimal vibration transmission—critical for maintaining sample integrity during high-speed pelleting of cellular and bacterial suspensions. Operating on the principle of radial acceleration-induced sedimentation, the LX-120T2Z generates up to 7,325 × g at its maximum speed of 12,000 rpm, enabling rapid separation of nucleic acids, proteins, organelles, and microbial cells from low-volume samples (1.5–2.0 mL). Its footprint—just 152 mm wide and 122 mm tall—allows seamless integration into biosafety cabinets, PCR workstations, and mobile diagnostic units without compromising ergonomic access or thermal management.
Key Features
- Compact palm-sized form factor (152 × 142 × 122 mm) optimized for benchtop, laminar flow hood, and field-deployable use
- Brushless DC motor with floating suspension damping system ensures mechanical stability and extended service life under repeated thermal cycling
- OLED display with real-time RPM/RCF readout, elapsed time, and countdown timer supports intuitive operation without external software
- Acoustic optimization achieving ≤50 dB(A) noise emission—validated per ISO 3744—enabling quiet operation in shared lab spaces and clinical settings
- Integrated safety interlocks: lid-open auto-stop, liquid leakage detection circuitry, and electronic overspeed protection compliant with IEC 61010-1:2010 safety standards
- Fixed-angle rotor configuration (8-position) designed for 1.5/2.0 mL microtubes; rotor imbalance tolerance ≤0.5 g per tube pair
Sample Compatibility & Compliance
The LX-120T2Z accommodates standard conical-bottom microcentrifuge tubes (1.5 mL and 2.0 mL), including PCR strip-compatible formats for parallel processing of up to eight reactions. It is routinely employed in applications requiring ISO/IEC 17025-aligned workflows—including nucleic acid extraction, bacterial pellet recovery post-culture, and protein precipitation prior to HPLC analysis. While not certified for clinical diagnostics under FDA 510(k) or CE-IVD, the device meets general-purpose laboratory equipment requirements per EN 61326-1 (EMC) and EN 61010-1 (safety). Its construction materials comply with RoHS Directive 2011/65/EU, and all electrical components are rated for continuous duty at ambient temperatures of 10–35 °C and relative humidity ≤80% non-condensing.
Software & Data Management
The LX-120T2Z operates as a standalone instrument with no embedded firmware-based data logging or network connectivity. All operational parameters—including run time, speed, and RCF—are displayed in real time on the integrated OLED screen but are not stored internally or exportable. This design aligns with GLP-compliant environments where manual recordkeeping (e.g., lab notebook entries or LIMS-integrated run logs) is mandated for audit traceability. For laboratories requiring electronic records under 21 CFR Part 11, external validation of operator-entered parameters and handwritten run documentation remains the responsibility of the end user.
Applications
- Routine pelleting of E. coli, S. aureus, and other Gram-positive/negative bacteria from liquid culture media
- Spin-down of PCR master mixes and post-amplification products to prevent tube wall condensation and ensure uniform reaction volume distribution
- Clarification of cell lysates prior to SDS-PAGE or Western blotting
- Concentration of viral particles or exosomes from conditioned media in virology and extracellular vesicle research
- Field-deployable centrifugation in public health emergency response units, where portability and battery-independent AC operation are essential
FAQ
Is the LX-120T2Z suitable for blood plasma separation?
No—it is not validated for whole-blood processing or serum/plasma separation, which typically require swing-bucket rotors, higher RCF (>10,000 × g), and strict hemolysis control protocols.
Can the rotor be autoclaved?
The fixed-angle rotor is constructed from anodized aluminum alloy and is compatible with autoclaving at 121 °C for 20 minutes; however, repeated sterilization may affect surface finish and torque calibration over time.
Does this centrifuge support timer-based automatic shutdown?
Yes—user-defined run durations from 10 seconds to 99 minutes can be programmed, with audible and visual alerts upon completion.
What is the minimum sample volume the device can handle reliably?
While rated for 1.5/2.0 mL tubes, consistent pelleting performance is maintained down to 100 µL when using low-retention microtubes and balanced loading.
Is rotor imbalance compensation available?
No—the LX-120T2Z relies on manual tube balancing; it does not feature active imbalance correction or load-sensing algorithms.
