Jiayuan TCLP-06 Fully Automated Tumbling Shaker for Solid Waste Leaching Extraction

Overview

The Jiayuan TCLP-06 Fully Automated Tumbling Shaker is an engineered solution designed specifically for regulatory-compliant leaching extraction of solid waste matrices in environmental laboratories. It operates on the principle of controlled tumbling agitation—rotating sample containers end-over-end at precisely defined angular velocity and dwell intervals—to simulate physical stress conditions required by standardized leaching protocols. This method ensures uniform contact between solid-phase samples and extraction fluids while minimizing particle segregation and wall adhesion artifacts. The system meets the mechanical and operational specifications outlined in two key U.S. EPA–aligned Chinese environmental standards: HJ/T 299–2007 (Sulfuric-Nitric Acid Leaching Method) and HJ/T 300–2007 (Acetic Acid Buffer Leaching Method), both widely adopted for toxicity characteristic leaching procedure (TCLP) and synthetic precipitation leaching procedure (SPLP) applications. Its robust architecture supports reproducible, traceable, and auditable leaching experiments under GLP-compliant workflows.

Key Features

• Programmable bidirectional tumbling mode: 2-minute forward rotation followed by 5-second pause, then 2-minute reverse rotation with identical pause—repeatable for up to 99 hours and 59 minutes; optional continuous unidirectional operation available.
• Digital microprocessor controller with LCD interface enabling independent adjustment of speed (0–60 rpm, ±1 rpm resolution), temperature (ambient to 65°C, ±0.1°C stability), and duration (0–99 h 59 min).
• Full 360° enclosed tumbling chamber constructed entirely from electropolished 304 stainless steel, ensuring corrosion resistance against acidic, basic, and organic leachants.
• Integrated safety systems include lid-activated power cutoff, ground-fault circuit interrupter (GFCI), and motor overcurrent protection—certified for continuous unattended operation.
• Single-tier stainless steel platform accommodates six 2-L extraction vessels (e.g., borosilicate glass, HDPE, or PTFE-lined bottles) with secure clamping fixtures to prevent displacement during motion.

Sample Compatibility & Compliance

The TCLP-06 accepts standard 2-L leaching containers compliant with ASTM D5233, EPA Method 1311, and ISO 14870:2015. Compatible vessel types include screw-cap glass bottles with inert liners, high-density polyethylene (HDPE) containers rated for chemical resistance, and fluoropolymer-coated vessels suitable for halogenated solvent extractions. All operational parameters—including rotational profile, thermal setpoint, and timing sequence—are fully configurable to satisfy method-specific requirements in HJ/T 299–2007 and HJ/T 300–2007. The unit’s thermal uniformity across the platform (±0.3°C max deviation at 65°C) and mechanical repeatability (CV < 1.2% across 10 consecutive runs) support data integrity for regulatory submissions to CNEMC, provincial EPBs, and third-party certification bodies.

Software & Data Management

While the TCLP-06 operates via embedded firmware without external PC connectivity, its control module logs all executed run parameters—including start time, target rpm, actual rpm average, set temperature, achieved temperature stability window, and total elapsed duration—into non-volatile memory. These records are viewable on the LCD panel post-run and can be manually transcribed for inclusion in laboratory notebooks or LIMS entries. For laboratories requiring electronic audit trails, the device supports integration with external data loggers via RS-232 output (optional accessory). All settings adhere to ALCOA+ principles when documented alongside chain-of-custody forms and analytical reports, facilitating FDA 21 CFR Part 11–aligned validation packages where electronic records are mandated.

Applications

• Toxicity Characteristic Leaching Procedure (TCLP) screening of municipal, industrial, and hazardous waste streams prior to landfill disposal or recycling.
• Extraction efficiency evaluation for heavy metals (Pb, Cd, Cr, Hg), semi-volatile organics (PAHs, PCBs), and oxyanions (As, Se, Mo) from soil, sediment, and sludge matrices.
• Method development and inter-laboratory comparison studies requiring strict adherence to HJ/T 299–2007 and HJ/T 300–2007 procedural fidelity.
• Quality assurance testing of stabilization/solidification (S/S) treated wastes to verify long-term leachate suppression performance.
• Research-scale leaching kinetics investigations under controlled thermal and mechanical boundary conditions.

FAQ

Does the TCLP-06 comply with U.S. EPA Method 1311?

Yes—the tumbling motion profile, temperature control range, and container compatibility align with the mechanical and environmental constraints specified in EPA Method 1311, though final regulatory acceptance depends on local accreditation scope.

Can I use it for SPLP (Synthetic Precipitation Leaching Procedure)?

Yes—its programmable timer and precise temperature regulation support SPLP’s 18-hour tumbling requirement at ambient conditions or elevated temperatures as needed for accelerated testing.

Is calibration documentation provided with shipment?

Each unit ships with a factory calibration certificate verifying rotational speed accuracy (±1 rpm), temperature sensor linearity (±0.1°C), and timer drift (< ±0.5 sec/hour) traceable to NIM-certified standards.

What maintenance is required for long-term reliability?

Routine cleaning of the stainless steel chamber and periodic inspection of drive belt tension and bearing lubrication (every 12 months under daily use) are recommended; no consumables are required.

Are custom platform configurations available for non-standard bottle sizes?

Yes—Jiayuan offers OEM engineering support for modified clamping fixtures, extended platforms, or dual-zone temperature control upon request, subject to minimum order quantities and lead time confirmation.
