Zhicheng ZWY-110X50 Reciprocating Water Bath Incubator Shaker

Overview

The Zhicheng ZWY-110X50 Reciprocating Water Bath Incubator Shaker is an engineered solution for precise temperature-controlled oscillation in life science laboratories. Designed for applications requiring simultaneous thermal regulation and mechanical agitation—such as microbial culture, enzymatic assays, hybridization protocols, and cell suspension maintenance—the instrument employs a reciprocating (linear back-and-forth) motion mechanism immersed in a thermostatically regulated water bath. This configuration ensures uniform heat transfer to samples via conduction through the water medium, minimizing thermal gradients and supporting high reproducibility across biological replicates. The unit integrates a robust electromechanical drive system with suspended buffer isolation to eliminate structural vibration transmission, achieving stable operation even under full load conditions. Its operational envelope spans ambient +5°C to 99.9°C, with temperature stability maintained within ±0.1°C resolution and ±0.2°C uniformity at standard incubation conditions (37°C, 100 rpm), meeting typical requirements for GLP-compliant microbiological and biochemical workflows.

Key Features

• Reciprocating oscillation platform with selectable stroke amplitudes (16 mm default; optional 24 mm) and frequency range of 20–180 rpm (±1 rpm accuracy)
• Dual overtemperature protection: independent cutoffs for low-water-level heater overheat and sample-zone thermal excursion
• Intelligent microprocessor controller with real-time LCD display of setpoint and actual temperature, oscillation speed, and remaining timer duration
• Auto-restart function after power interruption—resumes prior operating parameters without manual reconfiguration
• Programmable timer up to 500 hours with audible/visual alarm upon completion or thermal deviation exceeding ±3°C from setpoint
• Stainless steel electropolished tray and corrosion-resistant water bath chamber (568 × 360 × 250 mm internal volume) with integrated drain valve for maintenance efficiency
• Modular tray design supports interchangeable clamping configurations for flasks ranging from 100 mL to 1000 mL (max capacity: 24 × 100 mL, 15 × 250 mL, 11 × 500 mL, or 6 × 1000 mL)
• 2300 W heating capacity enables rapid thermal equilibration and sustained operation at elevated temperatures up to 99.9°C

Sample Compatibility & Compliance

The ZWY-110X50 accommodates standard laboratory glassware including Erlenmeyer flasks, test tubes, and culture bottles across multiple volume classes. Its water bath geometry and tray dimensions (494 × 316 mm) allow flexible arrangement of heterogeneous vessel types on a single platform. All wetted components—including the bath liner, tray, springs, and clamps—are fabricated from medical-grade stainless steel compliant with ISO 10993-1 for biocompatibility. While not certified to UL/CSA standards out-of-box, the device meets general electrical safety expectations for Class I laboratory equipment per IEC 61010-1. It supports audit-ready documentation practices when used in conjunction with validated SOPs and external calibration records aligned with ISO/IEC 17025 requirements. Optional integration with external recirculating chillers extends operational capability into sub-ambient temperature regimes (e.g., 4–25°C), enabling low-temperature fermentation or cold-active enzyme studies.

Software & Data Management

This model operates via embedded firmware without proprietary PC software dependency. All operational parameters—including temperature setpoint, oscillation speed, stroke selection, and timer duration—are configured directly via front-panel membrane keys and verified in real time on the monochrome LCD. The controller logs no raw data internally but provides traceable event indicators: temperature deviation alarms, timer expiration signals, and heater fault status. For regulatory environments requiring electronic record integrity (e.g., FDA 21 CFR Part 11), users may integrate the unit into broader lab infrastructure using external data loggers or PLC-based monitoring systems that capture analog outputs (if equipped) or relay-status triggers. Password-protected parameter locking prevents unauthorized modification during routine runs—a feature supporting GMP-aligned procedural controls.

Applications

• Bacterial and yeast cultivation under controlled thermal and agitation conditions
• Enzyme kinetics assays requiring constant mixing and narrow temperature tolerance
• Nucleic acid hybridization (e.g., Southern/Northern blotting) and antigen-antibody binding studies
• Suspension cell line maintenance and transfection optimization
• Fermentation process development for pharmaceutical intermediates and probiotic formulations
• Environmental microbiology testing—including water quality analysis and biodegradation rate studies
• Food safety validation protocols involving pathogen enrichment and selective media incubation

FAQ

Is the ZWY-110X50 compatible with external refrigerated circulators?
Yes—via optional auxiliary ports, the unit can interface with commercially available recirculating chillers to achieve stable sub-ambient operation down to approximately 4°C, subject to chiller performance and ambient lab conditions.

What is the maximum recommended fill level for the water bath?
The bath must be filled to at least 20 mm above the heater elements (minimum 8 L) and no higher than 20 mm below the top rim (maximum ~12 L) to ensure optimal thermal convection and prevent overflow during oscillation.

Can the stroke amplitude be changed during operation?
No—amplitude selection (16 mm or 24 mm) is a mechanical configuration performed during setup and requires tool-assisted adjustment of the eccentric cam; it is not dynamically adjustable while running.

Does the unit support RS-232 or USB connectivity for remote control?
No—this is a standalone instrument with no digital communication interfaces. All operations are executed locally via the front panel.

How often should the water bath be cleaned and disinfected?
We recommend weekly deionized water replacement and monthly cleaning with 70% ethanol or mild alkaline detergent, followed by thorough rinsing and drying to inhibit biofilm formation and mineral deposition.
