JIHEPU GH-100 Multi-Mode Orbital Shaker

Overview

The JIHEPU GH-100 Multi-Mode Orbital Shaker is an engineered laboratory platform designed for consistent, low-shear mixing across diverse sample formats under controlled mechanical agitation. Unlike vortex mixers or reciprocating shakers, the GH-100 employs a true horizontal 360° orbital motion—based on the Couette flow principle—to generate uniform radial acceleration across the entire working surface. This motion induces gentle yet effective convective mixing in liquid-phase samples without excessive foaming, phase separation, or cell lysis—making it especially suitable for suspension cultures, enzyme assays, immunoassays, and buffer equilibration where homogeneity and reproducibility are critical. Its robust AISI 304 stainless-steel construction ensures corrosion resistance in humid or chemically exposed environments, while the sealed digital control interface maintains operational integrity under routine lab cleaning protocols.

Key Features

• True horizontal 360° orbital motion with continuously adjustable speed (0–280 rpm) and frequency (0–360 cycles/min), enabling precise tuning for viscosity-sensitive applications.
• Mirror-finish stainless-steel platform (45 × 33 cm usable area) with integrated universal spring clamps—compatible with standard conical flasks (50–2000 mL), glass reagent bottles, PTFE-lined separatory funnels, and custom-adapted fixtures.
• Digital LED display showing real-time rotational speed and oscillation frequency, calibrated to NIST-traceable reference standards during factory verification.
• Low-noise brushless DC motor with thermal overload protection and electromagnetic braking for rapid, repeatable stop/start cycles.
• Stable base design with non-slip silicone feet and reinforced chassis geometry to minimize lateral displacement—even at maximum amplitude (20 mm) and full load (up to 8 kg distributed mass).
• Compliance-ready architecture: All electrical components meet IEC 61010-1 safety requirements for laboratory equipment; housing conforms to IP20 ingress protection rating.

Sample Compatibility & Compliance

The GH-100 accommodates heterogeneous vessel configurations without requiring platform recalibration—facilitating parallel processing of culture flasks, serum bottles, and extraction vessels within a single run. Its universal clamp system supports both rigid and flexible containers, including borosilicate glass, polypropylene, and PETG materials. For regulated environments, the shaker’s operational consistency aligns with common quality frameworks: it supports GLP-compliant record-keeping when paired with external data loggers, and its stable speed control meets ASTM D2709 (for emulsion stability testing) and ISO 8573-7 (for aerosol generation studies) prerequisites. While not inherently 21 CFR Part 11 compliant, audit trails can be generated via third-party software integration using RS-232 or optional USB interface modules.

Software & Data Management

The GH-100 operates as a standalone analog-digital hybrid instrument with no embedded firmware or network connectivity. However, its analog speed output signal (0–5 V DC) and TTL-compatible pulse train enable seamless integration with programmable logic controllers (PLCs), SCADA systems, or PC-based acquisition platforms such as LabVIEW™ or MATLAB®. Time-stamped operational logs—including duration, average RPM, and cycle count—can be captured externally using calibrated data loggers (e.g., Omega OM-DAQPRO-5300). For laboratories implementing electronic lab notebooks (ELNs), the device supports manual entry templates aligned with ISO/IEC 17025 documentation structures.

Applications

• Microbial and mammalian cell suspension culture maintenance in shake flasks (e.g., CHO, HEK293, E. coli BL21).
• Antibody-antigen binding kinetics studies requiring gentle, continuous agitation during incubation periods.
• Soil and water extract homogenization for environmental analysis (EPA Method 3510C).
• Pre-analytical sample preparation for HPLC, GC-MS, and ELISA workflows—including dilution series equilibration and reagent dispersion.
• Teaching laboratories: Demonstrating Newtonian fluid behavior, diffusion-limited mixing regimes, and Reynolds number effects in undergraduate biophysics curricula.

FAQ

Is the GH-100 suitable for high-viscosity solutions (e.g., >10,000 cP)?
The GH-100 is optimized for low-to-medium viscosity liquids (up to ~5,000 cP at 200 rpm). For higher viscosities, torque limitations may reduce effective amplitude; we recommend empirical validation using rheologically characterized standards.
Can the platform accommodate asymmetric loads (e.g., single large flask off-center)?
Yes—its balanced drive mechanism tolerates moderate load asymmetry (<30% mass offset), though optimal mixing uniformity is achieved with centered, symmetrical placement.
Does the unit include calibration documentation?
Each GH-100 ships with a factory-issued calibration certificate verifying speed accuracy ±2 rpm across the full 0–280 rpm range, traceable to national metrology institutes.
What maintenance is required for long-term reliability?
Annual inspection of motor bearings and clamp spring tension is recommended; no lubrication is required due to sealed bearing design and stainless-steel wear surfaces.
