CZGY GY-SYFZQ-06 Water-Bath Full-Temperature Inversion Shaker

Overview

The CZGY GY-SYFZQ-06 Water-Bath Full-Temperature Inversion Shaker is an engineered solution for standardized leaching toxicity testing of solid waste in compliance with regulatory protocols including EPA Method 1311 (TCLP), ISO 11372, and China’s HJ/T 299–2007 and HJ 557–2010. It operates on the principle of controlled 360° end-over-end inversion—mimicking natural percolation dynamics—within a precisely regulated water-bath environment. Unlike orbital or reciprocating shakers, this inversion mechanism ensures uniform, low-shear agitation critical for replicating field-relevant leachate generation without particle attrition or preferential channeling. The integrated water-bath system provides superior thermal homogeneity (±0.5 °C) across all sample positions compared to air-based heating, minimizing inter-vial temperature variance—a key requirement for GLP-compliant environmental testing laboratories.

Key Features

• Full-temperature water-bath control from 5 °C to 100 °C, enabled by dual-mode Peltier-assisted heating and cooling with internal recirculation for rapid equilibration and stable setpoint maintenance
• Precision inversion drive with adjustable frequency (5–100 rpm, ±1 rpm resolution) and fixed 20 mm amplitude—optimized for ASTM D5233 and EPA SW-846 compliant leaching kinetics
• Modular tray configuration supporting six 2 L polyethylene extraction bottles; fixtures are mechanically adjustable and compatible with custom container geometries (e.g., HDPE, glass, or stainless-steel vessels)
• 5-inch true-color capacitive touchscreen interface with intuitive icon-driven navigation, supporting both constant-mode operation and multi-segment programmable protocols (up to 50 steps, each configurable for time, temperature, and speed)
• Embedded PT100 temperature sensor with real-time feedback loop and independent over-temperature cutoff circuitry—certified for continuous unattended operation under ISO/IEC 17025-accredited workflows
• Robust stainless-steel water tank with corrosion-resistant coating, sealed circulation pump, and integrated drain valve for maintenance-free fluid management

Sample Compatibility & Compliance

The GY-SYFZQ-06 accommodates standard 2 L EPA-approved extraction vessels and supports method-specific adaptations for TCLP, SPLP, and synthetic precipitation leaching procedure (SPLP) protocols. Its mechanical inversion geometry meets the geometric tolerance requirements specified in US EPA SW-846 Chapter 7, ensuring reproducible tumbling motion regardless of fill level (25–100% capacity). The unit complies with IEC 61000-6-3 (EMC) and IEC 61010-1 (safety), and its firmware architecture supports audit-trail generation for 21 CFR Part 11–aligned data integrity when paired with validated LIMS integration. All wetted components are chemically inert to common leaching agents—including acetic acid buffer (pH 4.93), nitric acid solutions, and deionized water—ensuring no cross-contamination between test series.

Software & Data Management

The embedded controller logs timestamped temperature, speed, and elapsed time for each run with automatic CSV export via USB port. Programmable segments include ramp-hold profiles, enabling simulation of diurnal thermal cycles or staged pH adjustment protocols. Optional Ethernet or RS485 interfaces support remote monitoring and centralized fleet management through third-party SCADA or laboratory information systems. Calibration records—including sensor offset verification and speed validation using traceable tachometry—are stored locally with user-accessible read-only archives. Firmware updates are performed via signed binary packages to maintain cryptographic integrity and prevent unauthorized modification.

Applications

• Hazardous waste characterization per China’s National Standard GB 5085.3–2007 and EU Waste Framework Directive Annex III
• Leachate risk assessment for landfill liner compatibility studies and soil remediation validation
• Extraction efficiency optimization for heavy metals (Pb, Cd, Cr, As), cyanide, fluoride, and organic pollutants (PAHs, PCBs) from industrial sludges and mining tailings
• Method development and inter-laboratory comparison studies under CNAS-CL01 (ISO/IEC 17025) accreditation scope
• Regulatory submission support for RCRA, REACH, and RoHS compliance dossiers requiring auditable leaching data

FAQ

What regulatory leaching methods does the GY-SYFZQ-06 support?

It is configured to meet the mechanical and thermal specifications of EPA Method 1311 (TCLP), HJ 557–2010 (China), ISO 11372, and ASTM D5233, with validated inversion kinematics and thermal uniformity across the bath volume.
Can the shaker operate below ambient temperature?

Yes—the integrated thermoelectric cooling module enables stable operation down to 5 °C, even in environments up to 35 °C ambient, without external chiller dependency.
Is the system suitable for long-duration unattended runs?

Fully. With over-temperature protection, power-fail resume functionality, and non-volatile parameter storage, it supports continuous operation up to 9999 hours per program segment.
How is calibration verified and documented?

Factory calibration includes NIST-traceable PT100 verification and optical tachometer validation; users may perform periodic checks using certified reference standards and generate PDF-formatted calibration reports via USB export.
Are custom bottle fixtures available for non-standard containers?

Yes—CZGY offers engineering consultation and mechanical fixture prototyping for alternative vessel types (e.g., 500 mL glass jars, 5 L HDPE drums, or custom-machined clamps), subject to minimum order quantities and lead time confirmation.
