MKN HY-2A Digital Speed-Controlled Multi-Purpose Shaker

Overview

The MKN HY-2A Digital Speed-Controlled Multi-Purpose Shaker is an engineered solution for consistent, low-noise reciprocating motion in life science and industrial laboratory environments. Based on Couette-type mechanical oscillation principles, it delivers precise linear back-and-forth motion—ideal for mixing, extraction, suspension re-suspension, and gentle cell culture agitation where orbital or vortex action may cause shear-induced damage. Unlike rotary shakers, the HY-2A’s fixed-stroke (20 mm) reciprocating mechanism ensures uniform energy transfer across heterogeneous sample arrays without centrifugal displacement, making it especially suitable for applications requiring phase separation integrity—such as liquid-liquid extraction in environmental analysis or antibody incubation in immunoassay workflows. Its permanent-magnet DC motor provides high torque at low speeds and exceptional speed stability across the full 0–360 rpm range, minimizing thermal drift and mechanical resonance during extended operation.

Key Features

• Digital LED speed display with continuous, stepless adjustment from 0 to 360 rpm—enabling repeatable protocol execution and inter-laboratory method transferability.
• Dual-layer stainless steel universal spring clamp platform (50 × 30 cm), engineered for secure yet compliant retention of diverse vessels—including conical flasks (up to 2 L), separatory funnels, test tubes, and culture bottles—without slippage or deformation under load.
• Integrated mechanical timer (0–120 minutes) with auto-shutdown function, supporting unattended operation while maintaining compliance with GLP documentation requirements for time-critical assays.
• Low-vibration chassis design with reinforced base and rubber-damped feet, reducing ambient noise to <50 dB(A) at 200 rpm—critical for shared lab spaces and cleanroom-adjacent installations.
• Robust power regulation circuitry accommodating ±10% input voltage fluctuation, ensuring stable performance in variable utility conditions typical of regional research infrastructure.

Sample Compatibility & Compliance

The HY-2A accommodates standard ANSI/ISO-compliant glassware and polypropylene containers up to 20 kg total mass, including but not limited to: 15–50 mL centrifuge tubes, 125–2000 mL Erlenmeyer flasks, 500–1000 mL separatory funnels, and multi-well plate carriers (with optional adapter). Its reciprocating motion profile meets ASTM D2240-22 Annex A3 recommendations for low-shear mixing validation and aligns with USP environmental sampling preparation guidelines. While not certified for IEC 61000-6-3 EMC emission compliance out-of-box, its design conforms to general-purpose laboratory equipment safety standards per IEC 61010-1:2010 (Edition 3), including protection against electric shock, mechanical hazards, and abnormal temperature rise during sustained operation.

Software & Data Management

The HY-2A operates as a standalone analog-digital hybrid instrument with no embedded firmware or network interface. All operational parameters—including set speed, elapsed time, and remaining timer duration—are displayed locally via 3-digit red LED indicators. For laboratories implementing electronic lab notebooks (ELN) or LIMS integration, manual entry of run metadata (e.g., timestamp, speed, duration, vessel type) is supported through standardized CSV templates aligned with ISA-88 batch record conventions. Audit trails for calibration and maintenance are maintained externally per ISO/IEC 17025:2017 Clause 7.7; factory calibration certificates (traceable to NIM China) are supplied with each unit. Optional RS-232 output module (MKN-IO-232, sold separately) enables serial logging of real-time speed feedback for third-party SCADA systems.

Applications

• Environmental testing labs: Extraction of heavy metals from soil/sediment matrices using acid digestion protocols (EPA Method 3050B).
• Pharmaceutical QC: Reconstitution and homogenization of lyophilized reference standards prior to HPLC assay.
• Microbiology: Aerobic resuspension of biofilm fragments from static culture surfaces for CFU enumeration.
• Biotechnology R&D: Gentle agitation of hybridoma cultures during monoclonal antibody production phases where shear stress must remain below 0.5 Pa.
• Educational institutions: Undergraduate kinetics experiments involving iodine clock reactions or enzyme inhibition studies requiring reproducible mixing intervals.

FAQ

Is the HY-2A suitable for use with volatile organic solvents?
Yes—the stainless steel platform and sealed motor housing resist corrosion from common solvents including chloroform, ethyl acetate, and hexane. However, prolonged exposure to strong oxidizers (e.g., concentrated nitric acid) is not recommended.
Can the stroke length be adjusted?
No—the 20 mm stroke is mechanically fixed to ensure consistent amplitude repeatability and long-term bearing life. Variable-stroke configurations require custom engineering (contact MKN Technical Support for OEM inquiries).
Does the unit support external triggering or remote start/stop?
Not natively. The standard HY-2A lacks digital I/O ports. Integration with programmable logic controllers (PLCs) requires the optional MKN-IO-232 interface module and custom relay wiring.
What is the calibration interval recommendation?
Annual speed verification against a traceable tachometer is advised per ISO/IEC 17025:2017. Calibration records must include ambient temperature, line voltage, and load configuration used during verification.
Is CE or UL certification available?
The HY-2A complies with basic safety principles of IEC 61010-1 but is not CE-marked or UL-listed. Export customers requiring regional regulatory approval should consult MKN’s international compliance team for documentation packages supporting local conformity assessments.
