WIGGENS WS-100D Reciprocal/Orbital Shaker

Overview

The WIGGENS WS-100D Reciprocal/Orbital Shaker is a precision-engineered laboratory shaker designed for versatile agitation tasks in microbiology, molecular biology, cell culture, and biochemical assay development. It operates on dual-mode mechanical actuation—supporting both orbital (circular) motion with programmable forward/reverse/pause sequences and linear reciprocal (back-and-forth) oscillation—enabling optimal mixing for heterogeneous suspensions, sediment resuspension, hybridization reactions, and gentle cell detachment. Its brushless DC motor delivers consistent torque across the full 10–300 rpm range while minimizing electromagnetic interference, thermal drift, and mechanical wear—critical for long-duration incubation protocols requiring high reproducibility. The unit is engineered for continuous operation under ambient lab conditions (5–40 °C, 50–80% RH) and complies with IEC 61010-1 safety standards for laboratory electrical equipment.

Key Features

• Dual-mode oscillation: Selectable orbital (±180° rotation with user-defined forward/reverse/pause intervals) or reciprocal motion via intuitive digital interface
• PID-controlled speed regulation ensures ±1 rpm accuracy and stable rotational output—even under variable load conditions up to 7.5 kg
• LED-display digital control panel showing real-time rpm and remaining timer duration; all parameters adjustable via membrane keypad
• Anodized aluminum platform (350 × 350 mm) with corrosion-resistant surface and standardized mounting holes for universal clamp compatibility
• Stainless steel housing provides structural rigidity, EMI shielding, and resistance to common lab solvents and disinfectants
• Low-noise (<55 dB[A] at 1 m) and low-vibration operation enabled by precision-balanced drive mechanism and elastomeric isolation feet
• Programmable multi-step timing: Independent settings for forward duration, reverse duration, and pause interval—all configurable from 1 to 999 minutes

Sample Compatibility & Compliance

The WS-100D accommodates standard laboratory vessels including Erlenmeyer flasks (up to 2 L), round-bottom flasks, separatory funnels, Petri dishes, and multi-well plates when used with compatible clamps (e.g., spring-loaded universal clamps, rubber-coated platforms, or pre-mounted fixtures). Its open-platform architecture supports rapid reconfiguration for varying vessel geometries without tools. The device meets EN 61326-1 (EMC for laboratory equipment) and carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not an incubated shaker, its operational temperature envelope (5–40 °C) permits integration into cold rooms or temperature-controlled cabinets where external environmental control is applied.

Software & Data Management

The WS-100D operates as a standalone instrument with no embedded firmware-based data logging or PC connectivity. All operational parameters are set and monitored locally via the front-panel LED display and tactile controls. For GLP/GMP-aligned workflows requiring audit trails, users may integrate the shaker into validated environmental monitoring systems using external timers or PLC-triggered start/stop signals (via optional dry-contact input/output ports—available on select configurations). No proprietary software is required, eliminating licensing dependencies and ensuring long-term maintainability.

Applications

• Microbial growth studies requiring uniform aeration in liquid media (e.g., E. coli, yeast, or fungal cultures)
• Antibody-antigen binding assays and ELISA plate washing steps requiring precise reciprocating motion
• DNA/RNA extraction protocols involving phase separation and organic solvent mixing
• Cell dissociation and passaging using enzyme-based reagents under controlled agitation
• Standardization of sample homogenization prior to HPLC, GC, or spectrophotometric analysis
• Quality control testing of suspension stability in pharmaceutical formulations (per USP & Ph. Eur. general chapters on dissolution and dispersion)

FAQ

Is the WS-100D suitable for use inside a CO₂ incubator?

No—the unit is not rated for humidified, elevated-CO₂ environments. Its electronics and motor are designed for ambient lab air only. For incubator-integrated shaking, consider purpose-built incubator shakers with IP-rated enclosures.
Can the oscillation amplitude be changed during operation?

Yes—amplitude selection (20/30/40 mm) is made via front-panel menu before starting; changes require stopping the current cycle and reinitializing.
Does it support FDA 21 CFR Part 11 compliance?

Not natively—the device lacks electronic signature capability, audit trail generation, or user access control. It may be deployed in Part 11 environments only when paired with external validation documentation and procedural controls.
What clamp options are available for microcentrifuge tubes?

WIGGENS offers accessory kits including universal spring clamps (Order No. 200200C), pre-assembled platforms with fixed clamps (200300C), and rubber-mat platforms for low-profile vessels (200400C). Custom fixture design services are available upon request.
Is calibration certification included with purchase?

Factory calibration verification is provided with each unit. NIST-traceable calibration certificates are available as an optional add-on service through authorized WIGGENS service centers.
