WIGGENS WS-150D Reciprocal and Orbital Shaker

Overview

The WIGGENS WS-150D Reciprocal and Orbital Shaker is a dual-mode laboratory shaker engineered for precision, reliability, and operational flexibility in life science and bioengineering applications. Designed and manufactured to German engineering standards, it integrates both orbital (circular) and reciprocal (linear back-and-forth) motion modes within a single robust platform—enabling users to select the optimal agitation profile for cell culture, microbial growth, solubility studies, extraction protocols, or immunoassay incubation. Its brushless DC motor ensures low mechanical noise (<55 dB(A) at 1 m), minimal vibration transmission, and long-term torque stability across the full speed range. The unit operates on a PID-controlled closed-loop feedback system that maintains setpoint accuracy within ±1 rpm under variable load conditions—critical for reproducible biological assays and GLP-compliant workflows.

Key Features

• Dual-motion capability: Independently selectable orbital (clockwise/counterclockwise rotation with programmable pause intervals) and reciprocal oscillation modes—each configurable with user-defined timing sequences.
• Three amplitude options (20 mm, 30 mm standard, 40 mm) allow fine-tuning of shear stress and mixing intensity for sensitive cultures (e.g., suspension CHO cells) or high-viscosity media (e.g., agarose gels or fermentation broths).
• Full digital LED interface with intuitive keypad navigation enables real-time monitoring and adjustment of speed (10–300 rpm), total runtime (1–999 min), and individual phase durations (forward/reverse/pause cycles).
• Stainless steel chassis and anodized aluminum platform provide corrosion resistance, structural rigidity, and thermal stability—essential for extended unattended operation in controlled environments.
• Modular accessory compatibility: Accepts multiple plate configurations—including spring-clamp-ready plates, pre-mounted clamp assemblies, and elastomer-damped platforms—to secure Erlenmeyer flasks (50–5000 mL), round-bottom flasks, separatory funnels, and multi-well trays without slippage.
• Thermally rated for continuous operation between 5 °C and 40 °C ambient temperature, supporting integration into cold rooms or temperature-controlled laboratories without performance degradation.

Sample Compatibility & Compliance

The WS-150D accommodates standard laboratory vessels up to 5 L capacity per platform, with uniform motion distribution verified across the entire 450 × 450 mm surface area. Its 15 kg maximum load rating supports stacked flask configurations or multi-position microplate carriers when used with optional adapters. From a regulatory standpoint, the device meets IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards. While not intrinsically certified for use in classified hazardous locations, its non-sparking motor design and grounded metal enclosure align with general laboratory safety best practices outlined in ISO/IEC 17025:2017 Annex A.3 for equipment used in accredited testing laboratories.

Software & Data Management

The WS-150D operates as a standalone instrument with no embedded data logging or PC connectivity. However, its deterministic timing architecture—featuring independent forward/reverse/pause timers with 1-minute resolution—supports audit-ready protocol execution in regulated environments. When deployed in GxP settings (e.g., pharmaceutical QC labs), users may document operating parameters manually or integrate the shaker into broader lab automation systems via external programmable logic controllers (PLCs) using dry-contact relay outputs (available upon request with optional I/O module). All parameter settings are retained after power cycling, satisfying basic traceability requirements under FDA 21 CFR Part 11 for electronic records where local validation is performed.

Applications

• Mammalian and insect cell suspension culture in vented-cap flasks and bioreactor bags.
• Bacterial and yeast fermentation optimization under controlled aeration and mixing intensity.
• Antibody-antigen binding kinetics studies requiring precise agitation during incubation phases.
• Solubility and dissolution testing of APIs in buffered media per USP <711> guidelines.
• Western blot membrane washing steps where consistent reciprocal motion prevents uneven reagent distribution.
• Environmental microbiology sample homogenization prior to plating or nucleic acid extraction.

FAQ

Can the WS-150D be used inside a CO₂ incubator?

No—the unit is not rated for humidified, high-CO₂ atmospheres or elevated temperatures beyond 40 °C. It is intended for ambient or refrigerated laboratory environments only.
Is the 30 mm amplitude fixed, or can it be changed during operation?

Amplitude is mechanically selected via interchangeable platform inserts—changes require manual replacement and recalibration verification; it cannot be adjusted dynamically during a run.
Does the shaker support password-protected parameter locking?

No—this model lacks user-level access control. For secure protocol enforcement, external supervisory systems or physical key switches (optional add-on) are recommended.
What maintenance is required for long-term reliability?

Annual inspection of motor coupling integrity and platform leveling is advised. No routine lubrication is needed due to the sealed brushless DC motor design.
Are calibration certificates available for this instrument?

Factory calibration reports (speed and timer accuracy) can be provided upon request at time of order; third-party ISO/IEC 17025-accredited calibration services are supported through authorized WIGGENS service partners.
