DRETOP SHY-F4 Multi-Mode Variable-Speed Shaker

Overview

The DRETOP SHY-F4 Multi-Mode Variable-Speed Shaker is a robust, ambient-temperature laboratory shaker engineered for reproducible mechanical agitation of liquid and semi-solid samples in life science, biotechnology, environmental, and industrial R&D settings. Unlike temperature-controlled shakers (e.g., water bath or incubator shakers), the SHY-F4 operates exclusively at ambient conditions—making it ideal for applications where thermal stability is not required, but precise, low-maintenance mechanical mixing is critical. Its core mechanism employs reciprocating linear motion with a fixed 26 mm amplitude, driven by a brushless DC motor optimized for torque consistency across the full 0–300 rpm speed range. The device complies with IEC 61010-1 safety standards for laboratory electrical equipment and is constructed to meet GLP-aligned operational traceability requirements when paired with optional data logging accessories.

Key Features

• Brushless DC motor architecture ensures maintenance-free operation, consistent torque delivery, and long service life—eliminating carbon brush wear and commutation noise.
• Digital LED display provides real-time readout of set and actual speed (0–300 rpm), with ±1 rpm speed regulation accuracy under stable load conditions.
• Graduated analog speed control knob enables intuitive, stepless adjustment without software dependency—reducing training overhead and interface failure points.
• Slow-start ramp-up function minimizes initial sample disturbance, preventing splashing or foaming in low-viscosity cultures, reagents, or immunoassay plates.
• Overload protection circuitry automatically interrupts power if motor current exceeds rated threshold—preventing thermal damage during prolonged high-torque operation.
• Lockable control panel prevents accidental parameter changes during multi-user lab environments; settings persist through brief power interruptions.
• Compact footprint (440 × 270 × 250 mm) and lightweight design (<15 kg net) facilitate benchtop deployment in space-constrained cleanrooms or shared core facilities.

Sample Compatibility & Compliance

The SHY-F4 accommodates standard laboratory vessels—including Erlenmeyer flasks (up to 250 mL × 6), test tubes, centrifuge tubes, and microtiter plates—via its universal spring clamp fixture (stainless steel, included). It supports aqueous, organic, and mildly corrosive solutions within pH 4–10 and ambient temperature ranges (10–35°C). While not certified for hazardous location use (e.g., Class I Div 1), the unit meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). It is compatible with ISO/IEC 17025-accredited labs when used with documented SOPs and periodic performance verification (e.g., speed calibration using NIST-traceable tachometer).

Software & Data Management

The base SHY-F4 model operates without embedded firmware or network connectivity—ensuring deterministic response and eliminating cybersecurity exposure vectors common in IoT-enabled instruments. However, optional USB data logging modules (sold separately) enable time-stamped recording of speed, runtime, and on/off cycles in CSV format—supporting 21 CFR Part 11 compliance when deployed with validated electronic record systems. No cloud upload, remote access, or proprietary software installation is required or supported. All configuration remains local and non-volatile.

Applications

• Cell suspension homogenization prior to flow cytometry or viability assays
• Antibody-antigen binding kinetics in ELISA plate washing steps
• Solubility screening of small-molecule compounds in DMSO/water matrices
• Soil leaching studies for heavy metal extraction protocols (EPA Method 1311)
• Pre-analytical mixing of clinical specimens (serum, plasma, urine) before HPLC or mass spectrometry analysis
• Media preparation and reagent blending in QC microbiology workflows (ISO 11133-compliant)
• Extraction efficiency optimization in solid-phase extraction (SPE) cartridge conditioning

FAQ

Does the SHY-F4 include temperature control?
No. The SHY-F4 is an ambient-only shaker with no heating, cooling, or temperature sensing capability.
Can the oscillation mode be switched between reciprocating and orbital?
No. The SHY-F4 is configured exclusively for reciprocating (linear back-and-forth) motion per its mechanical design.
What is the maximum recommended load weight?
20 kg total mass, evenly distributed across the tray surface; exceeding this may degrade speed stability and accelerate mechanical wear.
Is the device suitable for GMP-regulated environments?
Yes—when operated with documented calibration, preventive maintenance logs, and integrated into a validated process workflow per Annex 11 and USP .
Are spare parts and service support available outside China?
DRETOP maintains authorized distributor networks in North America, EU, and APAC regions; technical documentation and motor replacement kits are supplied globally under warranty terms.
