Shiping ZD-810 Wrist-Action Shaker

Overview

The Shiping ZD-810 Wrist-Action Shaker is an engineered laboratory shaker designed to replicate the gentle yet effective motion of manual wrist agitation—ideal for applications requiring low-shear, uniform mixing of heterogeneous or shear-sensitive samples. Unlike orbital or reciprocating shakers, this device employs a controlled angular oscillation mechanism driven by a precision-balanced cam-and-linkage system coupled with sealed spherical bearings. The resulting motion approximates the natural arc of human wrist movement, minimizing bubble formation, foaming, and cell disruption while ensuring consistent suspension of particulates, precipitates, or immiscible phases. Its compact footprint and robust 304 stainless steel construction enable reliable deployment not only on benchtops but also within temperature- and humidity-controlled enclosures—including CO₂ incubators, environmental test chambers, and low-temperature refrigerated cabinets—provided ambient conditions remain within 4–40 °C and 20–80% RH (non-condensing).

Key Features

• Wrist-action oscillation with selectable tilt angles (3°, 6°, 9°, 12°) for optimized mixing intensity across sample viscosity and container geometry.
• Variable speed control from 50 to 600 rpm with ±1 rpm rotational accuracy, calibrated via PID-regulated microprocessor feedback loop.
• Maintenance-free sealed spherical bearing drive train—no lubrication required, eliminating contamination risk and reducing long-term operational downtime.
• High-strength 304 stainless steel chassis and articulated arm assembly, rated for continuous-duty loading up to 6.8 kg per side.
• Integrated electrical safety systems including leakage current protection and overcurrent cutoff, compliant with IEC 61010-1 for laboratory equipment safety.
• Compact form factor (320 × 272 × 452 mm) with extended arm configuration (320 × 810 × 452 mm), facilitating integration into constrained or climate-controlled spaces.

Sample Compatibility & Compliance

The ZD-810 accommodates a broad range of laboratory vessels without adapters, including standard reagent bottles (up to 1000 mL), Erlenmeyer flasks (500 mL), separatory funnels, volumetric flasks, narrow- and wide-mouth bottles, and graduated cylinders. Its adjustable arm clamping system supports containers with diameters up to 50 mm. The unit operates exclusively at ambient temperature (no integrated heating or cooling), making it suitable for protocols where thermal stability is externally managed. While not certified to ISO/IEC 17025 or FDA 21 CFR Part 11 out-of-the-box, its stable mechanical design, repeatable timing (via optional external timer integration), and parameter memory function support GLP-aligned documentation practices when paired with validated lab information management systems (LIMS).

Software & Data Management

The ZD-810 features a dedicated LCD interface with real-time display of setpoint and actual rpm, tilt angle selection, and elapsed time. It incorporates eight programmable user-defined segments for multi-step agitation protocols—enabling sequential changes in speed and duration without manual intervention. All parameters—including speed, angle, and runtime—are retained in non-volatile memory following power interruption (power-fail recovery). Though the device lacks Ethernet or USB connectivity, its analog-compatible output signals and stable analog control architecture allow seamless integration with building management systems (BMS) or PLC-based environmental monitoring platforms via 4–20 mA or 0–10 V auxiliary interfaces (available upon request with OEM configuration).

Applications

• Cell culture maintenance: Gentle resuspension of adherent or suspension cells prior to passaging or harvesting.
• Immunological assays: Uniform mixing of ELISA plates, antibody conjugates, and antigen-antibody complexes without denaturation.
• Environmental microbiology: Homogenization of water or soil extracts during MPN or membrane filtration preparation.
• Pharmaceutical QC: Reconstitution and dispersion of lyophilized standards, reference materials, and excipient blends.
• Forensic toxicology: Extraction and phase separation in liquid–liquid partitioning workflows using separatory funnels.
• Academic research: Reproducible agitation in kinetic solubility studies, crystallization screening, and polymer dissolution experiments.

FAQ

Can the ZD-810 be operated inside a CO₂ incubator?

Yes—the unit is rated for continuous operation in non-condensing environments between 4 °C and 40 °C with relative humidity up to 80%, meeting typical incubator specifications.
Is the tilt angle mechanically locked or continuously variable?

Tilt is discretely adjustable at four fixed positions (3°, 6°, 9°, 12°) via precision-machined indexing pins; no intermediate angles are supported.
Does the shaker include a built-in timer?

No internal timer is present on the ZD-810 model; timing must be managed externally or via user-programmed segments with elapsed-time tracking.
What is the maximum flask size supported without custom fixtures?

Standard configuration accommodates up to twelve 500 mL Erlenmeyer flasks or eight 1000 mL reagent bottles simultaneously.
How is speed calibration verified?

Speed accuracy (±1 rpm) is factory-validated using traceable optical tachometry; users may perform periodic verification with a handheld digital stroboscope or laser tachometer.
