MyiP 84-1A Six-Position Magnetic Stirrer

Overview

The MyiP 84-1A Six-Position Magnetic Stirrer is an engineered laboratory platform designed for parallel sample preparation under controlled agitation conditions. It operates on the principle of magnetic coupling—where a rotating permanent magnet or electromagnetic array beneath the work surface induces synchronous rotation of PTFE- or ceramic-coated magnetic stir bars immersed in vessels. This non-contact drive mechanism eliminates mechanical wear, seals contamination pathways, and enables operation inside enclosed environments such as laminar flow hoods or glove boxes. The device is calibrated using aqueous solutions (H₂O, 25 °C) as the reference medium, ensuring traceable performance benchmarks across its operational speed range. Its compact footprint and six independently controllable stations support high-throughput workflows common in analytical chemistry, pharmaceutical formulation development, buffer preparation, and quality control laboratories.

Key Features

• Six independent stirring channels: Each station features discrete speed control via dedicated rotary encoder or digital keypad interface, enabling simultaneous yet differentiated agitation protocols across multiple samples—critical for method optimization, dissolution testing, or comparative stability studies.
• Brushless DC motor drive: Delivers consistent torque output across the full 100–1500 rpm range with minimal thermal drift and no carbon brush degradation, ensuring long-term repeatability and reduced maintenance intervals.
• 304 stainless steel work surface: Chemically inert, corrosion-resistant, and compliant with ISO 15190:2020 laboratory safety standards; facilitates rapid decontamination between runs and withstands repeated exposure to solvents, acids, and bases.
• Compact benchtop form factor: With overall dimensions of 420 × 280 × 75 mm, the unit integrates seamlessly into space-constrained analytical labs while maintaining adequate clearance for standard 50–1000 mL glassware.
• Stable power regulation: Internal voltage regulation accommodates ±10% fluctuation in nominal 220 V AC supply—essential for reliable operation in regional infrastructure environments where grid stability is variable.

Sample Compatibility & Compliance

The MyiP 84-1A supports standard cylindrical and conical labware up to 1.5 L per position, including borosilicate glass beakers, Erlenmeyer flasks, and polypropylene bottles. Compatibility extends to low-viscosity aqueous and organic media (e.g., ethanol, acetone, PBS, TRIS-HCl buffers), provided magnetic stir bar geometry and size are matched to vessel diameter and fluid depth. While not rated for explosive atmospheres or Class I/II biological containment, the unit conforms to general-purpose electrical safety requirements per GB 4793.1–2019 (equivalent to IEC 61010-1) and electromagnetic compatibility (EMC) per GB/T 18268.1–2010. It is suitable for use in GLP-compliant environments when integrated into documented SOPs governing equipment qualification (IQ/OQ/PQ).

Software & Data Management

This analog/digital hybrid stirrer does not incorporate embedded firmware, network connectivity, or data logging capabilities. All operational parameters—including setpoint speed per station—are configured manually and retained only during active power-on cycles. For laboratories requiring audit trails or electronic records, external validation-compatible data loggers (e.g., compliant with FDA 21 CFR Part 11 via third-party integration) may be deployed to capture real-time RPM signals via optional tachometer outputs (available upon request with OEM accessory kit). No proprietary software is bundled; configuration remains fully manual and deterministic—reducing cybersecurity surface area and simplifying regulatory validation efforts.

Applications

• Preparation of homogeneous reagent solutions and calibration standards in analytical QC labs
• Parallel dissolution testing of solid dosage forms per USP <711>
• pH adjustment and titrant mixing in electrochemical cell setups
• Cell culture media equilibration prior to sterile filtration
• Extraction protocol development for environmental or food safety testing (e.g., AOAC 2017.16)
• Supporting ASTM D7984–15 (Standard Practice for Determining Mixing Efficiency in Liquid Systems) through multi-point viscosity correlation studies

FAQ

Is the MyiP 84-1A compatible with magnetic stir bars of varying lengths and coatings?

Yes—standard 20–40 mm PTFE- or PTFE/glass-coated stir bars are recommended for optimal coupling efficiency within the 1.5 L volume limit. Ceramic-coated bars may be used for elevated temperature applications up to 120 °C.
Can this unit operate continuously for extended periods (e.g., overnight)?

Yes—the brushless DC motor and thermally optimized chassis support unattended 24/7 operation under nominal load conditions, provided ambient temperature remains ≤35 °C and ventilation is unrestricted.
Does the device include overheat or stall protection?

Yes—a dual-stage thermal cutoff system disables individual station drivers if localized coil temperature exceeds 95 °C, preventing motor damage and ensuring compliance with IEC 60335-1 safety thresholds.
What is the expected service life under routine laboratory use?

With proper cleaning and avoidance of abrasive scrubbing on the stainless surface, the unit typically achieves ≥50,000 hours of operational duty cycle before scheduled recalibration or component replacement.
Is CE or UL certification available for export markets?

The base model meets EMC and LVD requirements per EN 61326-1 and EN 61010-1; CE marking documentation can be supplied upon order confirmation for EU-bound shipments. UL listing requires model-specific evaluation and is available under custom OEM agreement.
