Fast & Fluid SK550 Orbital Shaker Mixer

Overview

The Fast & Fluid SK550 Orbital Shaker Mixer is an electromechanically driven laboratory shaker engineered for reproducible, gravity-assisted orbital motion to achieve homogeneous mixing of liquid, semi-solid, and suspension-phase samples. It operates on the principle of controlled eccentric rotation—where a motor-driven eccentric mass induces smooth, circular horizontal displacement of the platform—generating consistent shear and convective forces across the sample volume. Unlike magnetic stirrers or overhead mixers, the SK550 delivers uniform agitation without internal components contacting the sample, eliminating cross-contamination risk and enabling compatibility with sealed, multi-vessel, or irregularly shaped containers—including elliptical, conical, and wide-mouth vessels commonly used in paint formulation, polymer dispersion, pharmaceutical suspension development, and industrial coating R&D. Its mechanical architecture integrates dynamic load balancing and passive damping to maintain stable operation at 680 cycles per minute—even under asymmetric loading conditions up to 40 kg total platform mass.

Key Features

• Graphical LCD interface with intuitive menu navigation and real-time parameter display (speed, elapsed time, remaining time)
• Soft-start acceleration profile to prevent splashing and ensure gentle initiation of orbital motion
• Height-adjustable support roller assembly with dual-position locking mechanism for vertical alignment of diverse vessel geometries
• Intelligent clamp-height detection system that verifies secure engagement before initiating motion—preventing unsecured operation
• USB-based firmware update and configuration transfer capability for centralized lab instrument management
• Dedicated mounting surface optimized for elliptical and non-circular containers, with configurable edge retention lips
• Four factory-preset timer intervals (1 min, 5 min, 15 min, 30 min), each independently assignable to user-defined protocols
• Multi-container support: simultaneous processing of up to four standard ISO 8573-1 compliant sample vessels (e.g., DIN 12450 bottles, ASTM D1839 jars) with independent weight distribution tolerance
• Bidirectional vibration mode available as optional configuration—enabling enhanced particle deagglomeration in high-viscosity dispersions

Sample Compatibility & Compliance

The SK550 accommodates a broad range of container types—including glass, stainless steel, HDPE, and PET vessels—with capacities from 50 mL to 5 L. Its adjustable clamping system and low-profile platform (60–450 mm height range) support both benchtop and fume hood integration. The device meets CE marking requirements per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and its construction adheres to IEC 61010-1:2010 safety standards for laboratory electrical equipment. While not intrinsically rated for hazardous area use, it is suitable for Class 1, Division 2 environments when operated with appropriate ventilation. For regulated laboratories, the SK550 supports traceable operation when paired with validated third-party data acquisition software compliant with FDA 21 CFR Part 11 requirements—including electronic signature, audit trail, and user access control functions.

Software & Data Management

The SK550 features embedded microcontroller firmware with USB 2.0 host capability, enabling direct connection to Windows- or Linux-based laboratory PCs. Firmware updates, protocol imports, and calibration log exports are performed via standard .csv or .xml file exchange. Optional software packages provide GMP-aligned workflow templates—including pre-defined SOPs for ASTM D2196 (viscosity of paints), ISO 8502-6 (surface cleanliness testing), and USP (disintegration time). All timing events, start/stop commands, and emergency stop activations are timestamped and stored locally for ≥10,000 cycles—facilitating retrospective analysis during internal audits or regulatory inspections.

Applications

The SK550 serves critical roles in raw material homogenization across multiple industrial sectors. In coatings and ink manufacturing, it ensures uniform pigment dispersion prior to rheological characterization or stability testing. In polymer R&D labs, it facilitates solvent blending and emulsion stabilization for acrylic, epoxy, and polyurethane systems. Quality control units utilize it for batch-to-batch consistency checks of suspensions (e.g., catalyst slurries, ceramic pastes, agrochemical concentrates). Its robust torque delivery and thermal-stable motor design also support extended-duration mixing protocols required for accelerated aging studies per ISO 2812-2 (resistance to humidity) and ASTM D714 (blistering evaluation).

FAQ

What container shapes does the SK550 support beyond standard cylindrical vials?
The platform is specifically engineered for elliptical, rectangular, and tapered containers—verified through DIN 53160-2 mechanical compatibility testing.
Is the 680 cycles/min speed adjustable in fine increments?
Yes—the speed is digitally controllable in 1-cycle/min steps across the full 100–680 cycles/min range via front-panel encoder or USB command.
Can the SK550 operate continuously for more than 8 hours?
Rated for continuous duty at nominal load (≤30 kg); thermal protection circuitry automatically reduces output if internal temperature exceeds 85°C.
Does the device include validation documentation for IQ/OQ protocols?
Factory-supplied documentation includes electrical safety test reports, mechanical performance verification sheets, and blank IQ/OQ checklists aligned with ISO/IEC 17025 requirements.
How is vibration isolation achieved during high-speed operation?
A dual-stage passive damping system—comprising elastomeric isolators and tuned mass absorbers—reduces transmitted vibration to ≤0.15 mm/s RMS at 680 cpm.
