Zhicheng ZWY-110X30 Reciprocating Water Bath Incubator Shaker

Overview

The Zhicheng ZWY-110X30 Reciprocating Water Bath Incubator Shaker is an engineered platform for precise temperature-controlled agitation of liquid-phase biological samples under uniform thermal conditions. Designed for applications requiring both stable thermal environments and consistent linear oscillation, this instrument employs a reciprocating motion mechanism—distinct from orbital or rotary shakers—to generate controlled back-and-forth displacement ideal for cell suspension, microbial culture, enzymatic assays, and hybridization protocols. Its integrated water bath chamber ensures superior thermal homogeneity across the entire sample zone, minimizing radial and vertical temperature gradients common in air-jacketed incubators. The unit operates on a robust mechanical drive system with suspended buffer mounts to eliminate structural vibration transmission, achieving near-silent operation (<50 dB(A)) and eliminating microtremor-induced artifacts in sensitive assays such as protein crystallization or low-biomass microbial growth monitoring.

Key Features

• Reciprocating oscillation mechanism with selectable stroke amplitude (16 mm standard; 24 mm optional) and adjustable frequency range (20–180 rpm, ±1 rpm accuracy)
• Dual-stage overtemperature protection: independent sensors monitor both water bath temperature and heater surface condition, automatically cutting power upon deviation exceeding preset thresholds
• Microprocessor-based PID temperature controller delivering ±0.1°C resolution and ±0.2°C uniformity at 37°C under operational load (100 rpm)
• Integrated dry-run prevention circuitry with level-sensitive cutoff to safeguard heating elements during low-water conditions
• Intelligent alarm system with audible/visual alerts triggered by temperature deviation >3°C from setpoint, timer completion, or power interruption events
• Non-volatile memory retains user-defined parameters—including speed, temperature, and timer settings—across power cycles
• Lockable LCD interface with real-time display of setpoints, actual values, and remaining timer duration (0–500 h)
• Stainless steel electropolished tray (434 × 256 mm), corrosion-resistant water bath tank (508 × 300 × 198 mm), and detachable universal clamping system compatible with Erlenmeyer flasks (100–500 mL), test tubes, and custom vessels
• Optional external chiller port enables sub-ambient operation down to 4°C when paired with certified recirculating refrigeration units

Sample Compatibility & Compliance

The ZWY-110X30 supports standardized laboratory vessel configurations including ISO-compliant 100 mL, 250 mL, and 500 mL Erlenmeyer flasks (up to 15, 11, or 6 units respectively), as well as multi-well plates and custom bioreactor inserts via adaptable tray accessories. Its stainless steel construction meets ISO 8573-1 purity requirements for non-contaminating surfaces in life science workflows. While not certified to IEC 61000-6-3 (EMC) or UL 61010-1 out-of-the-box, the device complies with GB/T 14710–2009 environmental testing standards for medical and laboratory equipment manufactured in China. For regulated environments, users may implement procedural controls—including calibration logs, maintenance records, and operator training documentation—to support GLP/GMP alignment during internal audits.

Software & Data Management

This model operates without proprietary software or USB connectivity; all configuration and monitoring occur via its embedded LCD interface. Parameter changes are logged internally with timestamped entries accessible through service mode (requiring authorized access code). Though lacking native FDA 21 CFR Part 11 compliance features such as electronic signatures or audit trails, the unit supports integration into validated laboratory information management systems (LIMS) via external data loggers connected to its analog output terminals (0–5 V DC proportional to temperature). Users performing IQ/OQ/PQ validation can document performance against ASTM E1229–22 (Standard Guide for Validation of Laboratory Equipment) using supplied calibration certificates and factory test reports.

Applications

The ZWY-110X30 serves critical roles in academic research laboratories, pharmaceutical QC/QA departments, and biotechnology process development facilities. Typical use cases include aerobic bacterial culture (e.g., Escherichia coli, Bacillus subtilis), yeast fermentation kinetics, DNA hybridization in Southern/Northern blotting, antigen-antibody binding optimization, and enzyme activity profiling under controlled thermal agitation. Its high thermal stability makes it suitable for long-duration incubations required in environmental microbiology (e.g., BOD testing per APHA Standard Methods 5210B) and molecular diagnostics assay development where reproducible heat transfer directly impacts reaction yield and specificity.

FAQ

What is the maximum operating temperature of the water bath?
The unit maintains temperatures from ambient +5°C up to 99.9°C with ±0.1°C resolution and ±0.2°C uniformity at 37°C.
Can the shaker operate continuously for extended periods?
Yes—designed for unattended 24/7 operation with automatic restart after power recovery and built-in thermal safety interlocks.
Is external refrigeration required for sub-ambient operation?
Yes; the base unit does not include active cooling. Sub-ambient capability requires connection to a compatible external recirculating chiller.
How is calibration verified for regulatory compliance?
Users must perform periodic verification using NIST-traceable RTD probes and document results per internal SOPs; factory calibration data is provided with each unit.
Are replacement trays and clamps available as spare parts?
Yes—Zhicheng offers modular tray assemblies, spring-loaded clamps, and flask-specific adapters under part numbers ZWY-T434, ZWY-C250, and ZWY-A500 respectively.
