Overview
The DRETOP AFZ6-1000 Tumbling Shaker is an engineered laboratory instrument designed for standardized solid-phase extraction and leaching procedures in environmental testing, regulatory compliance, and academic research. It operates on the principle of controlled tumbling motion—360° continuous or alternating-direction rotation—to replicate manual shaking while ensuring mechanical reproducibility, uniform sample agitation, and minimal operator variability. Unlike orbital or reciprocating shakers, the AFZ6-1000 delivers true end-over-end inversion, enabling complete suspension and contact between solid matrices (e.g., soil, sediment, sludge) and extraction solvents. This mechanism is essential for achieving equilibrium-based leaching efficiency required by standardized methods such as EPA Method 1311, TCLP, and Chinese Environmental Protection Standards HJ/T 299–2007 (Sulfuric-Nitric Acid Leaching Procedure) and HJ/T 300–2007 (Acetic Acid Buffer Leaching Procedure). Its robust aluminum-alloy frame, sealed drive system, and low-noise DC motor ensure long-term operational stability under repeated load cycling.
Key Features
- Programmable tumbling protocol: configurable forward-reverse alternation (e.g., 2 min forward → 5 sec pause → 2 min reverse → 5 sec pause) or continuous unidirectional rotation
- High-resolution digital timer with 1-second resolution and adjustable range from 0 to 9999 minutes (166.6 hours), supporting multi-step extraction workflows
- Temperature-controlled chamber (RT+5°C to 60°C) with PID-regulated heating and ±0.5°C uniformity across the platform
- Dual-mode operation: ambient mode for non-thermal extractions; thermostatic mode for temperature-dependent leaching protocols
- Load-balanced dual-axis drive system optimized for simultaneous agitation of six 1000 mL Erlenmeyer flasks or wide-mouth HDPE containers
- IP43-rated enclosure with reinforced safety interlock—automatically halts rotation when lid is opened during operation
- Compliance-ready design: meets mechanical and timing specifications outlined in HJ/T 299–2007 and HJ/T 300–2007 for regulatory submission of leachate data
Sample Compatibility & Compliance
The AFZ6-1000 accommodates standard 1000 mL extraction vessels—including borosilicate glass, polypropylene, and fluoropolymer-lined containers—with secure clamping fixtures that prevent slippage or spillage at up to 300 cycles per minute. Its tumbling geometry ensures full immersion and dynamic mixing of heterogeneous samples, including soils with high clay content, industrial sludges, fly ash, and municipal solid waste. The instrument is validated for use in GLP-compliant laboratories performing hazardous waste characterization, landfill leachability assessment, and contaminated site risk evaluation. All timing and temperature parameters are traceable via internal logging (non-volatile memory), supporting audit readiness per ISO/IEC 17025 requirements. No modifications to vessel geometry or sealing mechanisms are required to meet method-defined agitation intensity thresholds.
Software & Data Management
While the AFZ6-1000 operates via standalone front-panel control, its timer and temperature settings support manual documentation for SOP adherence. For integrated laboratory information management systems (LIMS), optional RS-232 or USB-to-serial interface modules enable external logging of start time, duration, setpoint temperature, and cycle completion status. All parameter changes are timestamped and stored locally for 10,000 event cycles—sufficient for routine QA/QC review and FDA 21 CFR Part 11-aligned electronic record retention when paired with validated third-party software. Calibration certificates for temperature sensor and timer accuracy are provided with each unit and conform to JJG 806–2007 (National Verification Regulation for Laboratory Shakers).
Applications
- Regulatory leaching tests for hazardous waste classification per GB 5085.3 and EPA SW-846 Method 1311
- Soil and sediment toxicity screening using acetic acid buffer extraction (HJ/T 300–2007)
- Heavy metal mobility studies in mining-impacted land remediation projects
- Pharmaceutical excipient solubility profiling under controlled agitation conditions
- Biodegradation kinetics experiments requiring sustained, low-shear tumbling of biofilm-coated substrates
- Standardized preparation of reference materials for ICP-MS and AAS analysis
FAQ
What standards does the AFZ6-1000 comply with for environmental leaching tests?
It is specifically configured to meet the mechanical and temporal requirements of HJ/T 299–2007 and HJ/T 300–2007, and is widely deployed in CNAS-accredited labs for TCLP-equivalent testing.
Can the shaker operate without temperature control?
Yes—the unit defaults to ambient-mode operation when temperature setpoint is disabled, maintaining full tumbling functionality at room temperature.
Is validation documentation available for GMP/GLP environments?
Yes: IQ/OQ documentation templates, calibration records, and traceable metrology reports are supplied upon request for audit support.
What maintenance is required for long-term reliability?
Annual verification of motor torque output, thermal sensor drift, and timer accuracy is recommended; no lubrication or belt replacement is required due to brushless DC motor architecture.
Are custom flask holders available for non-standard container sizes?
Yes—DRETOP offers OEM-compatible adapter plates for 500 mL, 2000 mL, and conical-bottom vessels, subject to mechanical load verification.
