Overview
The GLTLab SS-10N is a precision-engineered ten-position digital magnetic stirrer designed for high-throughput laboratory environments where consistent, parallel sample processing is essential. Utilizing permanent magnet coupling and microprocessor-controlled DC motor drives, the SS-10N delivers stable rotational torque across all ten independent stirring stations—each equipped with its own adjustable speed control and thermal feedback loop. Unlike analog multi-stirrers, this unit integrates digital PID temperature regulation and real-time RPM monitoring per position, enabling reproducible mixing conditions under controlled thermal environments up to 120 °C. Its compact footprint (230 × 540 × 84 mm) and low power draw (30 W) make it suitable for benchtop deployment in QC labs, pharmaceutical stability studies, chemical synthesis workflows, and academic research settings requiring simultaneous multi-vessel agitation.
Key Features
- Ten independently controllable stirring positions with individual LED digital displays for speed and temperature
- Speed range of 150–2000 rpm with ±2% speed accuracy and <1 rpm resolution
- Heated aluminum plate with uniform thermal distribution; temperature setpoint accuracy ±1 °C within 20–120 °C range
- Programmable timer function (0–999 min) with auto-shutdown capability per station or globally
- Robust stainless-steel housing and ceramic-coated heating plate resistant to chemical splashes and thermal cycling
- Optional serial communication interface (RS-232/RS-485) supporting SCPI command sets for integration into LIMS or automated lab platforms
- Low-noise operation (<45 dB(A)) and electromagnetic shielding compliant with IEC 61326-1 for EMC in shared instrumentation environments
Sample Compatibility & Compliance
The SS-10N accommodates standard laboratory glassware including 10–1000 mL beakers, Erlenmeyer flasks, and cylindrical reaction vessels with compatible magnetic stir bars (3–40 mm length). Its 130 × 500 mm plate geometry supports staggered placement of up to ten 100 mm-diameter vessels without interference. The unit meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to ISO/IEC 17025:2017 guidelines for equipment qualification in accredited testing laboratories. While not classified as GMP-grade hardware, its digital logging capability (when paired with optional software) supports audit-ready documentation aligned with FDA 21 CFR Part 11 principles for electronic records and signatures.
Software & Data Management
When configured with the optional GLTLab Control Suite (v3.2+), the SS-10N enables remote parameter configuration, real-time RPM/temperature trending, and CSV export of time-stamped operational logs—including start/stop timestamps, setpoint deviations, and error codes (e.g., overtemperature, stall detection). The software supports batch naming, user access levels (admin/operator), and automatic report generation compliant with GLP documentation standards. All data files are stored locally or on network drives with SHA-256 checksum validation to ensure integrity. No cloud storage is used by default; data residency remains fully under institutional control.
Applications
- Parallel dissolution testing in pharmaceutical development (USP Apparatus II equivalent setup)
- Multi-channel buffer equilibration and reagent preparation in molecular biology labs
- Catalytic reaction screening under controlled thermal-agitation conditions
- Standardization of viscosity reference solutions across multiple batches
- Environmental sample digestion protocols requiring uniform heating and agitation (EPA Method 3050B)
- Teaching laboratories performing comparative kinetics experiments with replicated conditions
FAQ
Does the SS-10N support individual temperature control per position?
No—temperature is regulated uniformly across the entire heating plate. Each position has independent speed control, but thermal setpoint applies globally.
Can I use non-magnetic vessels such as glass-jacketed reactors?
Yes, provided an internal stir bar is present and the vessel wall thickness does not exceed 12 mm. For double-walled systems, verify magnetic coupling efficiency using a test bar prior to protocol deployment.
Is calibration documentation provided with the instrument?
A factory calibration certificate (traceable to NIM, China) is included, covering speed and temperature verification at three points (500/1000/1800 rpm and 40/80/120 °C). Full IQ/OQ documentation templates are available upon request.
What maintenance is required for long-term reliability?
Annual inspection of thermal sensor contact integrity and periodic cleaning of the plate surface with isopropyl alcohol. No lubrication or mechanical adjustment is needed—the brushless DC motors are sealed and maintenance-free.
Is the RS-485 interface compatible with LabVIEW or Python-based control scripts?
Yes. Standard ASCII SCPI commands are supported (e.g., “SPEED?”, “TEMP 85”, “START 3”), and example drivers for LabVIEW 2020+ and Python 3.8+ (pySerial) are provided in the technical resource portal.
