Overview
The Langbo TCLB-6A Full-Temperature Inverting Shaker is an engineered platform for controlled, low-shear sample inversion under precisely regulated thermal conditions. Unlike orbital or reciprocating shakers, this instrument employs a true 180° rotational inversion mechanism—optimized for applications demanding uniform suspension, gentle phase mixing, or extended solid–liquid contact without foaming, emulsion destabilization, or particle attrition. Its dual-plate architecture enables parallel processing of two independent batches, each accommodating up to six 2 L vessels—making it suitable for extraction, leaching, dissolution testing, and environmental sample preparation where reproducible mechanical agitation and temperature stability are critical. The system operates on the principle of programmable angular displacement at defined rotational velocity and dwell time, ensuring consistent mechanical energy input across runs. Temperature control is achieved via PID-regulated heating elements integrated into the insulated chamber wall, maintaining setpoint accuracy within ±0.5°C across the full ambient+5°C to 60°C range.
Key Features
- Dual independent shaking plates—each configurable for synchronized or asynchronous operation
- Precision PID temperature control with real-time digital display and overtemperature cutoff
- Adjustable inversion speed: 0–45 rpm no-load; calibrated to 30 ±2 rpm under standard 2 L load (glass/PE/PTFE)
- Extended timer range (0–999 hours) supporting unattended overnight and multi-day protocols
- Robust stainless steel enclosure with electrostatic powder coating—resistant to solvents, acids, and cleaning agents
- Lightweight, corrosion-resistant aluminum alloy clamping fixtures with adjustable retention geometry
- Integrated electronic overload protection—automatically halts motion if torque exceeds safe threshold
- Front-access door with safety interlock switch and reinforced silicone gasket for thermal integrity
Sample Compatibility & Compliance
The TCLB-6A accommodates standard 2 L laboratory containers—including borosilicate glass bottles, high-density polyethylene (HDPE) carboys, PTFE-lined vessels, and ZHE (zirconium-hafnium-etched) inert containers—without adapter modification. Vessel orientation is secured via spring-loaded, height-adjustable clamps designed to minimize lateral movement during inversion. The instrument meets structural and electrical safety requirements per IEC 61010-1:2010 for laboratory equipment. While not certified to ISO/IEC 17025, its operational repeatability (±1.2% RSD in speed, ±0.4°C in temperature over 24 h) supports data integrity in GLP environments. It is routinely deployed in methods aligned with ASTM D3960 (extraction efficiency), USP (dissolution apparatus qualification), and EPA Method 1311 (TCLP leaching procedures).
Software & Data Management
The TCLB-6A operates via embedded microcontroller-based firmware with local parameter storage (10 user-defined protocols). All settings—including target temperature, inversion speed, duration, and plate activation status—are retained after power cycling. Optional RS-485 interface (Modbus RTU protocol) enables integration into centralized lab automation systems for remote monitoring and audit-trail logging. When connected to compliant LIMS or ELN platforms, timestamped run records—including start/stop times, temperature profiles, and fault events—can be archived with electronic signatures per FDA 21 CFR Part 11 requirements. No proprietary software installation is required for basic operation; configuration is performed via intuitive membrane keypad and LED display.
Applications
- Soil and sediment leaching studies (e.g., TCLP, SPLP) requiring standardized tumbling under controlled temperature
- Pharmaceutical dissolution testing of extended-release formulations using inverted bottle methods
- Environmental water analysis—extraction of PAHs, PCBs, and heavy metals from solid matrices
- Biopolymer solubilization and hydrogel swelling kinetics under thermal ramping protocols
- Cell lysate homogenization for downstream nucleic acid purification—minimizing shear-induced degradation
- Radiochemical separation workflows involving long-duration solvent extraction in shielded enclosures
FAQ
What is the maximum load capacity per plate?
Each plate supports six 2 L containers at rated speed (30 ±2 rpm); total mass per plate must not exceed 12 kg.
Can the shaker operate at temperatures below ambient?
No—it provides heating only, with minimum operating temperature at ambient +5°C.
Is validation documentation available for IQ/OQ/PQ protocols?
Yes—factory-generated test certificates (temperature uniformity mapping, speed calibration report, timer accuracy verification) are provided upon request.
Does the instrument support external temperature probes for chamber profiling?
Not natively; however, the RS-485 interface allows third-party probe integration via custom Modbus register mapping.
What maintenance is required for long-term reliability?
Annual inspection of belt tension, bearing lubrication, and thermal sensor calibration is recommended; no routine consumables are specified.
