Overview
The CZGY GY-FZQ-08S Full-Temperature Inverting Shaker is a precision-engineered laboratory instrument designed specifically for standardized leaching toxicity testing of solid waste in compliance with regulatory protocols. It operates on the principle of controlled, bidirectional rotational inversion—alternating between forward and reverse motion at programmable intervals—to simulate dynamic leaching conditions encountered during landfill percolation or environmental weathering. This mechanical action ensures uniform contact between solid-phase samples and extraction solvents (e.g., sulfuric–nitric acid mixture or acetic acid buffer), facilitating reproducible mass transfer kinetics essential for regulatory decision-making. The device integrates precise temperature control (5–60 °C) with high-resolution speed regulation (5–300 rpm, ±1 rpm accuracy) and extended timing capability (up to 9999 minutes), enabling uninterrupted execution of multi-day leaching protocols under thermostatically stabilized conditions.
Key Features
- Regulatory-compliant inversion mechanism: Programmable bidirectional rotation (default: 2 min forward → 5 sec pause → 2 min reverse → 5 sec pause), with optional continuous unidirectional mode
- Microprocessor-based digital control system with intuitive membrane keypad interface and real-time display of setpoint/actual values for temperature, speed, and elapsed time
- Stainless steel inner chamber and cold-rolled steel exterior with epoxy powder coating for corrosion resistance and long-term durability in humid or acidic environments
- Precision temperature control with ±0.5 °C stability across the full 5–60 °C range, including over-temperature alarm and automatic cut-off protection
- Adjustable stroke amplitude of 20 mm ensures effective agitation of high-viscosity or particulate-laden leachates without splashing or container displacement
- Modular shaker plate configuration supporting 8 standard 2-L zero-headspace extraction vessels (PE or HDPE); customizable to 4, 6, 10, or 12 positions upon request
- Full 360° sealed inversion design minimizes solvent evaporation and cross-contamination risk during extended operation
Sample Compatibility & Compliance
The GY-FZQ-08S is validated for use with standard EPA Method 1311 (Toxicity Characteristic Leaching Procedure) and Chinese Environmental Protection Standards HJ/T 299–2007 and HJ/T 300–2007. It accommodates common leaching containers—including zero-headspace extraction vessels (ZHEVs), polyethylene (PE) bottles, and high-density polyethylene (HDPE) jars—up to 2 L volume. All wetted components are chemically inert to acidic and buffered extraction media. The instrument meets general laboratory safety requirements per IEC 61010-1 and supports GLP-aligned documentation practices through traceable parameter logging (when integrated with external data acquisition systems). While not pre-certified to ISO/IEC 17025, its operational repeatability and calibration traceability enable users to establish in-house validation protocols compliant with CNAS, EPA, or EU WFD frameworks.
Software & Data Management
The GY-FZQ-08S employs embedded firmware without proprietary software dependency. All operational parameters—including temperature setpoint, speed, inversion cycle timing, and total duration—are stored in non-volatile memory and retained after power cycling. Optional RS-232 or USB-to-serial interfaces (available as field-upgrade kits) allow integration with laboratory information management systems (LIMS) or custom Python/Matlab scripts for automated parameter export and audit trail generation. Timestamped event logs (start/stop, alarm triggers, setpoint changes) support 21 CFR Part 11–aligned electronic recordkeeping when paired with validated third-party software platforms. No cloud connectivity or remote access functionality is included, preserving data sovereignty and network security in regulated environments.
Applications
- Hazardous waste characterization per national and international TCLP/SLT protocols
- Leachate generation for subsequent analysis by ICP-MS, AAS, IC, or HPLC
- Soil and sediment toxicity screening in environmental monitoring programs
- Pharmaceutical and agrochemical formulation stability assessment under simulated disposal conditions
- Research on contaminant mobilization kinetics in mining tailings, fly ash, or construction debris
- Method development and interlaboratory comparison studies requiring strict thermal and mechanical consistency
FAQ
Is the GY-FZQ-08S compatible with EPA Method 1311?
Yes—the mechanical inversion profile, temperature stability, and container compatibility align with the apparatus specifications outlined in EPA SW-846 Method 1311.
Can the shaker operate without temperature control?
Yes—ambient-mode operation is supported; the heating/cooling system can be disabled while retaining full speed and timing functionality.
What is the maximum load capacity per bottle position?
Each position supports up to 2 L of liquid-solid mixture; total system load must remain within the motor’s torque rating—consult technical documentation for weight-based derating guidelines.
Does the unit include calibration certificates?
Factory calibration reports for temperature and speed sensors are provided; user-performed periodic verification using NIST-traceable reference standards is recommended per ISO/IEC 17025 Clause 6.5.
Are replacement parts and service support available internationally?
CZGY provides OEM spare parts (shaker plates, drive belts, temperature sensors, control boards) and remote technical assistance; local authorized distributors handle warranty claims and on-site service in select regions.
