MKN HY-6 Dual-Layer Orbital/Reciprocating Shaker

Overview

The MKN HY-6 Dual-Layer Orbital/Reciprocating Shaker is an engineered platform for controlled mechanical agitation in life science, microbiology, biochemical, and industrial R&D laboratories. It operates on dual-mode oscillation mechanics—orbital (circular motion) and reciprocating (linear back-and-forth motion)—each independently configurable via dedicated drive systems. This architecture enables precise replication of diverse suspension, aeration, and mixing conditions required for microbial culture expansion, enzyme kinetics studies, cell suspension maintenance, and reagent homogenization. Unlike single-axis shakers, the HY-6 eliminates lateral displacement during operation through rigid base construction and balanced dual-layer tray mounting, ensuring stable placement on standard lab benches without anchoring. Its permanent magnet DC motor delivers consistent torque across the full speed range and maintains thermal stability under continuous load—critical for long-duration incubation-compatible shaking protocols.

Key Features

• Dual independent oscillation systems: Orbital and reciprocating modes can be activated separately or concurrently, supporting method flexibility across applications such as aerobic bacterial growth (orbital) and particle resuspension (reciprocating).
• Electronic speed control with digital display: Provides stepless adjustment from 0 to 250 rpm with ±2 rpm repeatability, enabling method transfer between instruments and labs.
• High-load dual-tier platform: Upper and lower trays each support up to 20 kg, accommodating up to 40 × 500 mL Erlenmeyer flasks or 50 × 250 mL flasks simultaneously while maintaining amplitude integrity (≥20 mm peak-to-peak displacement).
• Noise-optimized drive assembly: Permanent magnet DC motor coupled with low-vibration mounting and precision-balanced eccentric mechanisms reduces operational noise to <55 dB(A) at 1 m distance—suitable for shared laboratory spaces.
• Programmable timer with auto-shutdown: 0–120 minute countdown function ensures protocol adherence and prevents over-agitation; system powers down automatically upon completion.
• Benchtop-stable chassis: Reinforced steel frame with non-slip rubber feet prevents migration during high-speed operation—a common failure mode observed in legacy shaker designs.

Sample Compatibility & Compliance

The HY-6 accommodates standard laboratory vessels including glass and plastic Erlenmeyer flasks (100–1000 mL), test tubes (up to 50 mL), petri dishes, and multi-well plates (via optional adapters). Its open-platform design supports airflow around samples, making it suitable for ambient-temperature shaking applications. While not an incubated shaker, its mechanical stability and low electromagnetic interference allow integration into temperature-controlled rooms or laminar flow hoods. The instrument is designed for use in GLP- and ISO/IEC 17025-regulated environments: all operational parameters (speed, time, mode) are manually set and recorded externally, supporting audit-ready documentation practices. It complies with IEC 61010-1 safety standards for electrical equipment used in laboratory settings and meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU).

Software & Data Management

The HY-6 is a standalone hardware platform with no embedded microprocessor or network interface. All parameter inputs—including speed, oscillation mode, and timer duration—are configured via front-panel rotary dials and push-button controls. This analog-digital hybrid architecture prioritizes reliability, reproducibility, and service longevity over connectivity features. Users maintain full traceability by recording operational settings in lab notebooks or LIMS-integrated electronic records prior to initiation. For laboratories requiring electronic data capture, optional external USB or RS-232 data loggers (sold separately) may be interfaced using standard TTL-level signals provided at the rear I/O port. No proprietary software is required, eliminating licensing dependencies and compatibility risks associated with firmware-updated instruments.

Applications

• Microbial culture propagation: Aerobic growth of Escherichia coli, Bacillus subtilis, and yeast strains in liquid media using orbital agitation at 150–220 rpm.
• Cell suspension maintenance: Gentle agitation of mammalian or insect cell cultures in serum-free or low-serum media to prevent sedimentation without shear-induced damage.
• Enzyme assay preparation: Homogenization of substrate-enzyme mixtures prior to kinetic measurement, particularly where gas exchange or particle dispersion is required.
• Environmental sample processing: Extraction and mixing of soil suspensions, waterborne pathogen concentrates, and wastewater sludge samples prior to filtration or analysis.
• Reagent and buffer equilibration: Uniform temperature distribution and dissolution enhancement for viscous or particulate-containing solutions prior to downstream use.
• Quality control testing: Reproducible agitation cycles for stability testing of pharmaceutical suspensions per USP <711> and EP 2.9.40 guidelines.

FAQ

Is the HY-6 compatible with incubators or environmental chambers?
No—the HY-6 is a benchtop shaker without integrated temperature control. However, its low heat dissipation (<8 W standby, <35 W max load) and absence of internal fans make it suitable for placement inside externally temperature-regulated enclosures, provided adequate ventilation is maintained.
Can both layers operate at different speeds or modes simultaneously?
No—both trays share the same speed setting and oscillation mode selection. Independent control per layer is not supported in this model.
What safety certifications does the HY-6 hold?
It conforms to IEC 61010-1:2010 for laboratory electrical equipment and meets EMC Directive 2014/30/EU requirements. A full Declaration of Conformity is available upon request.
Does the unit include flask clamps or universal platforms?
Standard configuration includes two flat, non-perforated stainless-steel trays. Optional accessories—such as universal spring-loaded clamps, tube racks, and microplate holders—are available separately.
What is the expected service life under continuous operation?
With routine maintenance (biannual lubrication of drive shafts and visual inspection of belt tension), the permanent magnet DC motor and mechanical linkage are rated for >20,000 hours of operation at rated load.
