DRETOP WYC-110X30 Constant-Temperature Water Bath Shaker

Overview

The DRETOP WYC-110X30 Constant-Temperature Water Bath Shaker is an engineered platform for precise, reproducible incubation and agitation of biological and biochemical samples under controlled thermal and mechanical conditions. It operates on the principle of water-mediated temperature uniformity combined with linear reciprocating motion—optimized for applications requiring gentle yet consistent mixing in aqueous environments. Unlike air-jacketed shakers, the water bath design ensures superior thermal homogeneity (±0.3°C uniformity) across the entire chamber, minimizing thermal gradients that can compromise cell viability, enzyme kinetics, or microbial growth consistency. The unit is widely deployed in academic life science laboratories, pharmaceutical QC/QA facilities, clinical diagnostics labs, and environmental testing centers where regulatory compliance, traceability, and experimental repeatability are critical.

Key Features

• Microprocessor-based PID temperature and speed control system with backlit LCD display—enabling real-time monitoring of setpoint vs. actual temperature (resolution: 0.1°C), rotational speed (±1 rpm accuracy), and elapsed time.
• Brushless DC motor drive delivering maintenance-free operation, constant torque across full speed range (0–220 rpm), and silent, vibration-damped performance without carbon brush wear or electromagnetic interference.
• Dual-safety architecture: independent overtemperature cutoff (with audible/visual alarm), motor overheat protection, and automatic power disconnection upon thermal runaway or sensor failure.
• Soft-start ramping algorithm prevents sample splashing during initiation—critical for low-volume cultures, fragile suspension cells, or viscous media.
• Parameter lock function secures operational settings against accidental modification; power-loss recovery retains user-defined protocols and resumes operation post-interruption.
• Stainless-steel water bath chamber (490 × 310 × 250 mm) with corrosion-resistant interior and spill-proof sealing; compatible with standard laboratory glassware including Erlenmeyer flasks (up to 250 mL × 11), test tubes, and microtiter plates when used with optional universal spring clamps.

Sample Compatibility & Compliance

The WYC-110X30 supports a broad spectrum of liquid-phase biological samples—including bacterial and mammalian cell cultures, enzymatic reaction mixtures, antigen-antibody binding assays, DNA hybridization buffers, and environmental water extracts. Its RT + 5°C to 100°C operating envelope accommodates both mesophilic cultivation (e.g., E. coli at 37°C) and high-temperature applications such as protein denaturation studies or agarose gel pre-melting. The unit complies with IEC 61010-1:2010 safety standards for laboratory equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified for GMP manufacturing environments out-of-the-box, its data logging capabilities (via optional USB module) support GLP-compliant documentation when integrated into validated workflows adhering to FDA 21 CFR Part 11 principles for electronic records.

Software & Data Management

The base configuration includes embedded firmware with non-volatile memory for storing up to 10 user-defined protocols. Optional USB data logger enables continuous timestamped recording of temperature, speed, and runtime—exportable as CSV for audit-ready analysis. Advanced configurations support external integration via RS-232 or analog output (0–5 V) for connection to LIMS or SCADA systems. Touchscreen upgrade kits (sold separately) extend functionality to paperless recordkeeping, wireless remote status monitoring (Wi-Fi-enabled), and real-time thermal profile printing via compact thermal printers—all aligned with ALCOA+ data integrity expectations.

Applications

• Microbial growth curve analysis and antibiotic susceptibility testing (AST)
• Cell suspension culture maintenance for hybridoma or CHO lines
• Enzyme kinetics assays requiring simultaneous thermal stabilization and mixing
• Extraction efficiency optimization in environmental sample preparation (e.g., PAHs from soil leachates)
• Antigen retrieval in immunohistochemistry protocols
• Pre-analytical sample homogenization prior to HPLC or mass spectrometry injection
• Quality control of diagnostic reagents under accelerated stability conditions

FAQ

What is the maximum load capacity for the platform?
The shaker supports up to 8 kg distributed evenly across the 435 × 260 mm platform. For optimal thermal uniformity and mechanical stability, loads exceeding 5 kg should be centered and secured using spring clamps.
Can this unit operate continuously for extended periods (e.g., 72+ hours)?
Yes—the brushless motor and reinforced bearing assembly are rated for unattended operation up to 168 hours, provided ambient temperature remains below 30°C and water level is maintained above minimum fill line.
Is calibration documentation available for ISO/IEC 17025 traceability?
Factory calibration certificates (NIST-traceable temperature and speed verification) are provided with each unit; field recalibration services are available through DRETOP-authorized service partners in APAC and EU regions.
Does the water bath require deionized or distilled water?
Use of deionized water is strongly recommended to prevent mineral scale buildup on heating elements and temperature sensors—extending service intervals and maintaining ±0.1°C control accuracy over time.
How is condensation managed during low-temperature operation near RT+5°C?
The unit does not include active condensation suppression; users operating near ambient dew point should employ insulated lid covers or desiccant trays within the chamber to minimize moisture accumulation on samples and optics.
