GLTlab SS-6N-500 Six-Position Thin-Profile Magnetic Stirrer with 500 mL Capacity per Position

Overview

The GLTlab SS-6N-500 is a six-position, thin-profile magnetic stirrer engineered for high-throughput benchtop mixing in quality control laboratories, pharmaceutical R&D environments, and academic research settings where spatial efficiency and operational consistency are critical. Unlike conventional multi-station stirrers with bulky housings or limited speed resolution, the SS-6N-500 employs brushless DC motor technology coupled with high-strength neodymium magnetic drive systems to deliver stable rotational torque across its full 100–2000 rpm range. Its stainless steel chassis—just 60 mm tall—minimizes vertical footprint while maintaining structural rigidity and chemical resistance, enabling seamless integration beneath fume hoods, inside laminar flow cabinets, or on crowded analytical workbenches. As a non-heated device, it operates strictly at ambient conditions, making it suitable for temperature-sensitive protocols involving enzymatic reactions, polymer dissolution, buffer equilibration, or reagent homogenization where thermal drift must be avoided.

Key Features

• Ultra-low profile design (60 mm height) optimized for space-constrained laboratory environments
• Six independent stirring positions with individual speed control and identical performance characteristics
• Brushless DC motor architecture ensures low electromagnetic interference, extended service life, and consistent torque delivery up to 2000 rpm
• Digital LED display with intuitive keypad interface for precise speed setting and real-time monitoring
• Optional programmable timer function supports unattended operation with automatic shutdown
• RS232 or USB communication interface available for integration into LIMS or automated liquid handling platforms via standard SCPI or Modbus RTU protocols
• Stainless steel housing provides corrosion resistance, ease of decontamination, and compliance with cleanroom-compatible maintenance practices
• Compatible with standard PTFE-coated stir bars (lengths 20–40 mm recommended) and glass or plastic vessels up to 500 mL per position

Sample Compatibility & Compliance

The SS-6N-500 accommodates a wide range of sample containers—including borosilicate glass beakers, polypropylene centrifuge tubes, and custom reaction vials—provided magnetic coupling remains effective (i.e., vessel wall thickness ≤ 8 mm and non-ferromagnetic material). It is validated for use with aqueous solutions, organic solvents (e.g., ethanol, acetone, DMSO), and moderately viscous media (up to ~500 mPa·s at 25°C) when paired with appropriately sized stir bars. While not certified to specific regulatory standards such as FDA 21 CFR Part 11 or ISO 13485, the device is constructed and tested in accordance with IEC 61010-1 for electrical safety in laboratory equipment. Its digital control system supports audit-ready operation when used within GLP/GMP frameworks requiring traceable parameter logging (via external data acquisition).

Software & Data Management

No proprietary software is bundled with the base unit; however, the optional serial/USB interface enables bidirectional communication using industry-standard terminal emulators or custom Python/LabVIEW scripts. Users may log speed setpoints, runtime duration, and error codes (e.g., overload detection, sensor fault) into CSV or SQL databases. When deployed in regulated environments, timestamped operation records can be synchronized with electronic lab notebooks (ELNs) supporting ASTM E2500 or ISO/IEC 17025 documentation requirements. Firmware updates—delivered via secure HTTPS download—are signed and version-controlled to ensure integrity during field deployment.

Applications

• High-throughput buffer preparation and dilution series generation across six parallel samples
• Homogenization of cell culture media prior to sterile filtration or dispensing
• Accelerated dissolution testing of solid dosage forms in USP Apparatus II-equivalent configurations
• Pre-analytical sample conditioning for HPLC, ICP-MS, or ELISA workflows
• Controlled mixing during titration pre-equilibration or calibration standard preparation
• Supporting ISO 5725-2 repeatability studies requiring identical agitation parameters across replicates

FAQ

Does the SS-6N-500 include heating functionality?

No. This model is a dedicated magnetic stirrer without integrated heating elements or temperature sensors. For combined stirring and heating, refer to GLTlab’s SH-series hotplate stirrers.
Can it operate continuously for 24 hours?

Yes—when operated within its specified ambient temperature range (15–35°C) and loaded with appropriate stir bars, the brushless motor supports uninterrupted duty cycles exceeding 72 hours under typical laboratory loads.
Is calibration required before use?

Speed calibration is not mandatory for routine applications; however, users performing ISO/IEC 17025-accredited testing may perform periodic verification using an optical tachometer traceable to NIST standards.
What power supply does it use?

Standard 100–240 VAC, 50/60 Hz input. An external DC power adapter (12 V, ≥3 A) is supported for mobile or off-grid deployment but must be sourced separately.
Are replacement stir bars included?

No. PTFE-coated stir bars (recommended: 30 mm × 8 mm) are sold separately to accommodate varying viscosity and vessel geometry requirements.
