WIGGENS TM-1 Series Vortex Mixer

Overview

The WIGGENS TM-1 Series Vortex Mixer is a precision-engineered laboratory vortex shaker designed for reproducible, high-efficiency mixing of small-volume samples in tubes, vials, and microcentrifuge containers. Utilizing a brushless DC motor coupled with microprocessor-controlled speed regulation, the TM-1 delivers stable rotational motion across its full 0–2500 rpm range without torque drop or thermal drift. Its compact footprint (115 × 230 × 60 mm) and low center-of-gravity design ensure mechanical stability during operation—even at maximum speed—minimizing vibration transmission to adjacent instrumentation. Unlike orbital shakers or reciprocating mixers, the TM-1 employs true vortex motion: a rapid, circular displacement of the platform generating controlled centrifugal acceleration that induces turbulent fluid motion within sample vessels. This principle ensures homogeneous suspension of particulates, efficient re-suspension of pellets, and consistent lysis of cellular material—critical for downstream applications in molecular biology, clinical diagnostics, and pharmaceutical QC.

Key Features

• Brushless DC motor for maintenance-free operation, zero spark emission, and extended service life under continuous duty cycles
• Two activation modes: momentary touch-start (ideal for intermittent mixing) and continuous run (for timed or unattended protocols)
• Analog speed control via calibrated rotary knob with linear scale display—enabling intuitive, repeatable setting without software dependency
• Fixed 4.5 mm orbital amplitude optimized for standard 0.2–50 mL tube formats; ensures vigorous yet non-destructive mixing of sensitive biological matrices
• Aluminum-plastic composite housing offering mechanical rigidity, ESD-safe surface properties, and resistance to common lab solvents and disinfectants
• Modular platform interface supporting rapid interchange of accessories—including universal vortex platform, 96-well microplate holder, tube rack inserts, and custom foam adapters for irregularly shaped vessels
• Low power draw (17.3 W) and ambient-temperature operation eliminate need for external cooling or ventilation infrastructure

Sample Compatibility & Compliance

The TM-1 accommodates a broad spectrum of primary sample containers: 0.2 mL PCR tubes, 1.5/2.0 mL microcentrifuge tubes, conical-bottom centrifuge tubes up to 50 mL, and standard 96-well plates when fitted with the optional microplate platform. Its mechanical design conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment, and carries CE marking under the EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. RoHS 2011/65/EU compliance guarantees restricted substance management across all PCBs, housings, and motor components. While not certified for ISO 13485 or FDA 21 CFR Part 11 environments, the TM-1’s deterministic analog control architecture supports GLP-compliant documentation when integrated into validated workflows—particularly where audit trails rely on operator-recorded settings rather than electronic logs.

Software & Data Management

The TM-1 operates as a standalone analog instrument with no embedded firmware, network interface, or data logging capability. This architecture eliminates cybersecurity vulnerabilities, firmware update dependencies, and calibration drift associated with digital controllers. Speed settings are manually recorded by users in lab notebooks or LIMS entries—a practice aligned with traditional GLP documentation requirements for simple mixing steps. For laboratories requiring traceability enhancements, WIGGENS offers optional time-limited timer modules (sold separately) compatible with the TM-1’s auxiliary input port, enabling hands-free termination after preset intervals. No proprietary software, drivers, or cloud services are required or supported.

Applications

• Routine resuspension of lyophilized reagents, bacterial cell pellets, and protein precipitates prior to electrophoresis or chromatography
• Homogenization of immunoassay reagents, ELISA coating buffers, and antigen-antibody complexes
• Pre-analytical preparation of whole blood, serum, plasma, and urine specimens for clinical chemistry analyzers
• Mixing of viscous solutions (e.g., glycerol stocks, agarose gels, polymerase master mixes) without bubble formation
• Supporting ISO 17025-accredited testing procedures where mechanical consistency—not digital validation—is the primary metrological requirement
• Integration into automated workcells via dry-contact trigger inputs (available on TM-2 variant), though the TM-1 remains optimized for manual benchtop use

FAQ

Is the TM-1 suitable for mixing hazardous or volatile samples?
Yes—the brushless DC motor produces no electrical arcs, and the PP-free aluminum-plastic housing resists corrosion from organic solvents. However, use only in well-ventilated areas or fume hoods when handling volatile compounds.
Can the TM-1 accommodate 50 mL conical tubes?
Yes, when used with the optional high-capacity tube rack adapter (Order No. 360130); standard platform supports up to 15 mL tubes natively.
Does the TM-1 require periodic calibration?
No—its analog speed control and mechanical governor deliver inherently stable rpm output across voltage fluctuations; verification against a handheld tachometer every 6 months is recommended for ISO-compliant labs.
What is the expected service life under daily usage?
With proper cleaning and avoidance of liquid ingress, the brushless motor and sealed electronics support ≥50,000 hours of operational lifetime per IEC 60068-2-64 reliability testing.
Are replacement platforms available for purchase separately?
Yes—WIGGENS supplies OEM-certified platforms including microplate holders (360140), foam insert kits (360150), and universal vortex discs (360160), all mechanically interchangeable with the TM-1 base unit.
