MENTS GS-10 Orbital Shaker

Overview

The MENTS GS-10 Orbital Shaker is an engineered platform for consistent, low-shear horizontal mixing in life science laboratories. It operates on the principle of orbital motion—generating a smooth, circular displacement with a fixed 10 mm diameter orbit—ideal for suspension cultures, cell proliferation assays, enzyme reactions, and reagent homogenization where gentle yet uniform agitation is critical. Designed for reliability in routine microbiology, molecular biology, and bioprocess development workflows, the GS-10 integrates a brushless DC motor drive system that ensures speed stability across its full 50–300 rpm range, minimal electromagnetic interference, and maintenance-free operation over extended service intervals. Its compact footprint (280 × 270 × 110 mm) and universal AC input (100–230 V) support deployment in multi-user core facilities, BSL-2 cabinets, and incubator-integrated environments.

Key Features

• Brushless DC motor: Delivers precise speed control, high torque at low rpm, silent operation, and >20,000-hour service life without carbon brush replacement or lubrication.
• Microprocessor-based control system: Enables real-time LCD display of both set and actual speed (rpm) and remaining timer duration (mm:ss or hh:mm format).
• One-knob intuitive interface: Eliminates menu navigation; rotary encoder allows direct parameter adjustment with tactile feedback and immediate confirmation.
• Soft-start acceleration profile: Gradually ramps up to target speed within 8–12 seconds to prevent splashing, foam formation, or disruption of delicate cell monolayers.
• Programmable timer: Adjustable from 1 minute to 100 hours (99 h 59 min), with audible end-of-run alert and automatic shutdown to ensure protocol compliance and energy efficiency.
• Modular tray system: Interchangeable PP-1 (petri dish), PP-2 (medium-capacity flask), and PP-3 (high-density flask) platforms enable rapid adaptation to diverse vessel formats without tools.

Sample Compatibility & Compliance

The GS-10 accommodates standard laboratory vessels used in aerobic culture, immunoassay plate washing, and buffer equilibration. Its 2.5 kg max load capacity supports simultaneous processing of up to 12 × 100 mL Erlenmeyer flasks (with PP-3 tray) or 8 standard petri dishes (PP-1). All trays are autoclavable (121 °C, 20 min) and chemically resistant to common solvents, acids, and bases. The unit complies with IEC 61000-6-3 (EMC emission standards) and IEC 61010-1 (safety requirements for electrical equipment for measurement, control, and laboratory use). While not certified for GMP production environments, its repeatable performance, traceable timer functionality, and non-volatile parameter memory support GLP-aligned documentation practices in academic and preclinical labs.

Software & Data Management

The GS-10 operates as a standalone instrument with no embedded software or network connectivity. All operational parameters—including speed, time, and run status—are retained in non-volatile memory during power interruption and restored upon restart. For laboratories requiring electronic recordkeeping, the device’s stable mechanical behavior and deterministic timer output allow integration with external data loggers via analog voltage output (optional accessory module available upon request). No proprietary drivers or cloud services are required. The interface design aligns with FDA 21 CFR Part 11 principles for manual entry integrity: all settings are confirmed by physical knob rotation and visually verified on the LCD before initiation.

Applications

• Microbial growth studies: Uniform aeration of E. coli, yeast, and fungal suspensions in liquid media.
• Cell culture maintenance: Gentle rocking of adherent cells during medium exchange or transfection protocols.
• ELISA and Western blotting: Consistent agitation during blocking, antibody incubation, and wash steps.
• Biochemical assay preparation: Homogenization of protein lysates, antigen-antibody complexes, and chromatography sample loading buffers.
• Environmental microbiology: Mixing of water samples with enrichment broths prior to membrane filtration or MPN analysis.
• Education labs: Demonstrating kinetic effects of agitation rate on reaction yield and microbial doubling time.

FAQ

Is the GS-10 compatible with CO₂ incubators?
Yes—the unit is rated for continuous operation at ambient temperatures between 4 °C and 45 °C, and its sealed motor housing and low heat dissipation (<45 W) make it suitable for placement inside standard humidified CO₂ incubators when mounted on stable, vibration-dampened shelves.
Can the shaker be operated without a tray?
No—trays are mechanically interlocked with the drive shaft and serve as the primary load-bearing interface; operation without a tray may damage the coupling mechanism and void warranty.
Does the GS-10 support external triggering or RS-232 communication?
Not natively. It is a manually controlled instrument. However, third-party TTL-triggered relay modules can be integrated via the optional auxiliary I/O port (contact factory for pinout specifications).
What is the tolerance for speed accuracy across the 50–300 rpm range?
Speed deviation is ≤ ±1.5% of set value under full 2.5 kg load at 25 °C ambient, verified per ISO 17025-accredited calibration procedures using laser tachometry.
Are replacement trays and fuses available as spare parts?
Yes—PP-1, PP-2, and PP-3 trays, along with 2 A slow-blow ceramic fuses (5 × 20 mm), are stocked and shipped globally with 48-hour dispatch from Beijing warehouse.
