Overview
The Jingrongyuan JRY-XZ10 Constant-Temperature Tumbling Oscillator is an engineered laboratory instrument designed specifically for standardized solid waste toxicity leaching extraction procedures, including those specified in EPA Method 1311 (TCLP), EPA Method 1312 (SPLP), ISO 11372:1995, and China’s HJ/T 299–2007 and HJ/T 300–2007 standards. It operates on the tumbling (end-over-end rotation) principle—where sample bottles are rotated at a fixed angle (typically 30° from horizontal) at controlled speed and temperature—to simulate leaching conditions under regulatory compliance protocols. Unlike orbital shakers or reciprocating agitators, this design ensures uniform, low-shear contact between solid matrix and leaching solution, minimizing particle attrition while maximizing analyte mass transfer kinetics. The unit integrates precise thermal regulation with programmable timing to support batch reproducibility across multi-day extraction experiments.
Key Features
- Robust enclosure constructed from cold-rolled steel with epoxy-polyester anti-corrosion coating, rated for continuous operation in humid or chemically exposed lab environments.
- Single front-access door with magnetic latch and sealed gasket ensures thermal integrity and simplifies bottle loading/unloading without disrupting adjacent samples.
- Integrated transparent acrylic observation window enables real-time visual monitoring of bottle rotation, liquid level, and suspension homogeneity without opening the chamber.
- Microprocessor-based PID temperature controller with digital display provides stable setpoint maintenance across the full operating range (ambient to 65 °C), with accuracy certified at ±2 °C per IEC 61000-4-30.
- Programmable timer supports durations from 1 minute up to 9999 minutes (≈7 days), with auto-shutdown and audible alert upon cycle completion.
- Tumbling motion driven by a brushless DC motor coupled to a precision gear train, delivering consistent 30 rpm rotation (adjustable within ±5% via firmware calibration) with minimal vibration transmission.
Sample Compatibility & Compliance
The JRY-XZ10 accommodates standard 1-L or 2-L EPA-approved HDPE or borosilicate glass leaching bottles (e.g., ASTM D5231-compliant containers) across its 10-position carousel. Each holder features silicone-lined clamps and angular alignment guides to maintain the required 30° tilt during rotation. The system meets mechanical and thermal requirements for TCLP, SPLP, and China’s HJ series methods. While not individually certified to ISO/IEC 17025, the device is manufactured under ISO 9001:2015 quality management systems, with documented traceability for critical components (temperature sensor, motor driver, control board). It supports GLP-aligned workflows when paired with external audit logs and user-defined SOPs.
Software & Data Management
The JRY-XZ10 operates via embedded firmware with local keypad interface; no PC connectivity or proprietary software is included. All operational parameters—including set temperature, elapsed time, remaining time, and current chamber temperature—are displayed in real time on a 4-digit LED screen. For laboratories requiring electronic records, optional RS-232 or USB-to-serial adapters enable integration with LIMS or custom Python/Excel-based logging scripts. When used in regulated environments (e.g., environmental testing labs under CNAS or EPA ELAP accreditation), users must implement manual logbook entries or third-party validation protocols to satisfy 21 CFR Part 11 requirements for electronic signatures and audit trails.
Applications
- Toxicity Characteristic Leaching Procedure (TCLP) screening for RCRA-regulated hazardous waste classification.
- Synthetic Precipitation Leaching Procedure (SPLP) for assessing metal mobility under acid rain scenarios.
- Leachate generation for subsequent analysis by ICP-MS, AAS, IC, or GC-MS for heavy metals, anions, and organic contaminants.
- Method development and validation studies for alternative leaching protocols (e.g., pH-dependent extractions).
- Soil, sediment, sludge, and construction/demolition debris characterization in municipal and industrial waste management facilities.
FAQ
What bottle sizes and materials are compatible with the JRY-XZ10?
Standard 1-L and 2-L HDPE, PET, or borosilicate glass bottles conforming to ASTM D5231 specifications can be loaded directly; custom holders are available upon request for non-standard geometries.
Does the unit support ramp-and-soak temperature profiles?
No—the JRY-XZ10 maintains a single user-defined setpoint throughout the run; multi-stage thermal programming requires external environmental chambers or hybrid setups.
Is calibration documentation provided with shipment?
A factory calibration certificate for the NTC temperature sensor (traceable to NIM, China) is included; annual recalibration against a reference thermometer (e.g., Fluke 1523) is recommended per ISO/IEC 17025 Clause 6.5.
Can the rotation speed be adjusted?
Rotation is fixed at 30 rpm ±1.5 rpm as required by EPA 1311 and HJ/T 299; speed modification voids method compliance and is not supported in firmware.
What maintenance is required for long-term reliability?
Monthly inspection of door seal integrity, quarterly cleaning of condensate drain port (if operated above ambient dew point), and biannual lubrication of carousel bearing points using food-grade silicone grease.
