Xiangyi WTL-4K Mini Benchtop Centrifuge

Overview

The Xiangyi WTL-4K Mini Benchtop Centrifuge is an engineered solution for rapid, low-force sedimentation tasks in molecular biology, clinical diagnostics, and routine laboratory workflows. Designed around a fixed-angle rotor architecture, it operates on the principle of centrifugal force generation via rotational acceleration—applying radial acceleration to sample containers to separate components based on density differentials. With a maximum speed of 4,000 rpm and a peak RCF of 900 × g, the WTL-4K delivers sufficient force for pelleting nucleic acids, precipitating proteins, clarifying lysates, and recovering reagents from tube walls or caps—particularly effective for PCR setup, spin-down of filtration columns, and pre-sequencing cleanup steps. Its compact footprint (160 × 200 × 123 mm) and palm-sized form factor enable deployment on crowded benchtops, biosafety cabinets, or mobile lab carts without compromising structural stability or thermal management.

Key Features

• Brushless DC motor with zero maintenance requirements—ensures consistent torque delivery, extended service life (>10,000 h MTBF), and minimal heat generation during repeated operation.
• Lid-actuated safety interlock system: motor halts immediately upon lid opening, meeting IEC 61010-1 mechanical safety provisions for operator protection.
• Acoustic optimization via patented vibration-damping housing and precision-balanced rotor assembly—operates below 45 dB(A) at full speed, suitable for quiet environments including teaching labs and cleanrooms.
• Dual-rotor compatibility: includes a 6-position fixed-angle rotor for 1.5 mL tubes and an interchangeable adapter plate supporting 0.2 mL PCR strips (8-well format), 0.2 mL, 0.5 mL, and 1.5 mL microcentrifuge tubes.
• Full transparent polycarbonate lid enables real-time visual monitoring of sample integrity and rotor status without interrupting operation.
• Digital electronic timer with adjustable range (0–99 minutes or continuous mode) and automatic rotor brake—prevents sample resuspension during deceleration.
• Universal power input (AC 100–242 V, 50/60 Hz) eliminates need for voltage converters in international laboratories; built-in surge and overcurrent protection circuits ensure operational resilience.

Sample Compatibility & Compliance

The WTL-4K accommodates standard conical-bottom microcentrifuge tubes (1.5 mL, 0.5 mL, 0.2 mL) and rigid 8-strip PCR plates with standardized footprint dimensions. All rotors and adapters are manufactured from high-strength aluminum alloy (EN AW-6061-T6), anodized for corrosion resistance and validated for repeated autoclaving (121 °C, 20 min). The device complies with IEC 61010-1:2010 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and carries CE marking under the EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). While not certified to ISO 13485 or FDA 21 CFR Part 11, its design supports GLP-aligned documentation practices when paired with external audit-trail-capable LIMS systems.

Software & Data Management

The WTL-4K operates as a standalone instrument without embedded firmware-based data logging or network connectivity. All operational parameters—including run time, speed setting, and start/stop timestamps—are set manually via front-panel controls. For laboratories requiring traceability, integration into electronic lab notebooks (ELNs) or quality management systems (QMS) is achieved through manual entry or barcode-scanned protocol referencing. Optional third-party USB-based data loggers (e.g., HOBO UX120-006M) may be deployed externally to record ambient temperature and runtime events for retrospective validation.

Applications

• Routine spin-down of PCR master mixes prior to thermal cycling to eliminate air bubbles and ensure uniform distribution.
• Recovery of enzymatic reaction components adhered to tube caps or sidewalls after brief incubation steps.
• Clarification of crude cell lysates or antibody supernatants prior to electrophoresis or ELISA preparation.
• Centrifugal elution from silica-membrane spin columns used in plasmid DNA or RNA isolation kits.
• Low-speed consolidation of small-volume samples (e.g., blood spot eluates, forensic swab extracts) where excessive RCF could cause shearing or aerosol formation.
• Teaching applications in undergraduate biochemistry and microbiology labs—demonstrating sedimentation kinetics, rotor dynamics, and centrifugal force calculation principles.

FAQ

What is the maximum relative centrifugal force (RCF) achievable with the WTL-4K?

The WTL-4K achieves a maximum RCF of 900 × g at 4,000 rpm with the standard 1.5 mL rotor.
Can the WTL-4K accommodate 0.2 mL PCR strips?

Yes—the instrument includes an optional adapter plate compatible with standard 8-well PCR strips (0.2 mL per well).
Is the rotor autoclavable?

Both the aluminum rotor and all tube adapters are autoclavable at 121 °C for 20 minutes; however, the main unit housing must never be autoclaved.
Does the WTL-4K support programmable protocols or memory recall?

No—it features only manual parameter selection and lacks onboard protocol storage or USB export capability.
What safety certifications does the WTL-4K hold?

It meets IEC 61010-1:2010 for laboratory electrical safety and carries CE marking under applicable EU directives.
