PULUODY PLD-GS2 Digital Orbital Shaker

Overview

The PULUODY PLD-GS2 Digital Orbital Shaker is an engineered laboratory instrument designed for precise, reproducible horizontal circular motion (orbital oscillation) to facilitate homogeneous mixing, suspension, and aeration of liquid samples. Operating on the principle of eccentric cam-driven orbital motion—where the platform rotates in a fixed-diameter circle without vertical displacement—the shaker ensures uniform energy transfer across all sample vessels placed on its surface. This mechanism minimizes shear stress on sensitive biological cultures while maintaining consistent agitation intensity across variable vessel types and fill volumes. The device is optimized for ambient-temperature applications in standard laboratory environments (10–40 °C, <80% RH), supporting both short-term mixing protocols and extended incubation-compatible shaking when integrated with environmental chambers.

Key Features

• Digital LED interface with independent real-time display of rotational speed (rpm) and remaining timer duration—enabling immediate verification and repeatable parameter recall.
• Adjustable speed range from 30 to 300 rpm with ±1 rpm resolution and closed-loop feedback control for stable operation under varying load conditions.
• Precision-engineered eccentric drive system with reinforced timing belt transmission, delivering low-vibration performance (<0.5 mm orbit diameter) and acoustic output ≤50 dB(A) at 1 m distance.
• 300 × 300 mm stainless steel platform with corrosion-resistant surface finish and integrated spring-loaded clamping slots compatible with universal bottle holders (e.g., Erlenmeyer flasks, test tubes, centrifuge tubes, and custom-fit adapters).
• Programmable mechanical timer (1–999 minutes) with auto-shutdown function; non-volatile memory retains last-used settings after power interruption.
• Robust powder-coated steel chassis with anti-slip rubber feet and overload protection circuitry compliant with IEC 61000-4-2/4-3 EMC standards.

Sample Compatibility & Compliance

The PLD-GS2 accommodates diverse vessel geometries—including conical flasks (50–2000 mL), culture tubes (12–50 mm diameter), microplates (96-well format with optional plate holder), and custom containers—via interchangeable clamp assemblies (standard spring clips, universal bottle racks, or user-defined fixtures). All materials contacting the platform meet ISO 8573-1 purity class 5 requirements for non-contaminating surfaces. The unit complies with ISO 9001:2015 quality management systems and conforms to GB/T 12803–2021, the Chinese national standard for orbital shakers specifying mechanical stability, speed accuracy, and safety thresholds. It supports GLP-compliant workflows through traceable operational parameters and is routinely validated per ASTM E2500–22 (Guide for Specification, Design, and Verification of Pharmaceutical and Biopharmaceutical Manufacturing Systems).

Software & Data Management

While the PLD-GS2 operates as a standalone analog-digital hybrid instrument without embedded PC connectivity, its operational parameters are fully documentable within laboratory notebooks and electronic lab notebooks (ELNs) via manual entry or barcode-scanned protocol templates. For audit readiness, users may integrate the shaker into broader QC/QA systems using external data loggers (e.g., HOBO UX120 or Omega OM-DAQPRO-5300) that record speed, runtime, and ambient temperature. The device satisfies FDA 21 CFR Part 11 requirements for electronic records when used in conjunction with validated ELN platforms featuring electronic signatures, audit trails, and role-based access controls.

Applications

• Chemical analysis: Homogenization of reagent solutions, dissolution testing, extraction kinetics, and standard solution preparation per USP & EP monographs.
• Microbiological cultivation: Aerobic bacterial growth in liquid media (e.g., E. coli, Bacillus subtilis), yeast propagation, and fungal spore dispersion.
• Environmental testing: Extraction of heavy metals from soil/sediment matrices (EPA Method 3050B), leachate analysis, and wastewater nutrient mixing.
• Life sciences: Cell suspension maintenance, antibody conjugation reactions, ELISA plate coating steps, and DNA/RNA hybridization support.
• Quality control laboratories: Stability studies, particulate matter dispersion in injectables, and viscosity assessment of low-shear-thinning fluids.

FAQ

What is the maximum load capacity of the PLD-GS2 platform?
The platform supports up to 5 kg distributed evenly across the surface. Overloading may compromise speed stability and accelerate bearing wear.
Can the PLD-GS2 be operated inside a CO₂ incubator or cold room?
Yes—provided ambient operating conditions remain within 10–40 °C and relative humidity does not exceed 80%. Optional IP54-rated enclosure kits are available for enhanced environmental protection.
Is calibration documentation provided with the instrument?
Each unit ships with a factory-verified calibration certificate referencing NIST-traceable tachometer standards and includes instructions for user-performed speed verification using an optical tachometer.
Are replacement clamps and platform inserts available?
Yes—PULUODY offers OEM-certified accessories including universal flask racks (for 125–1000 mL), microplate carriers, tube holders (13–16 mm), and custom-machined fixtures upon engineering drawing submission.
Does the PLD-GS2 meet international electrical safety standards?
It carries CE marking per EN 61010-1:2010+A1:2019 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and complies with RoHS 2011/65/EU restrictions on hazardous substances.
