Overview
The MyPu MYP16 Heavy-Duty Integrated Magnetic Stirrer with Precision Weighing System is an engineered solution for laboratories and pilot-scale production environments requiring concurrent high-volume mixing and real-time mass monitoring. Unlike conventional magnetic stirrers or standalone balances, the MYP16 integrates a robust dual-coil electromagnetic drive system with a calibrated load-cell-based weighing platform—both housed within a single monolithic stainless-steel frame. Its operation relies on contactless torque transmission via rotating permanent magnets beneath the work surface, enabling consistent agitation of viscous or heterogeneous media without mechanical wear. The weighing subsystem employs temperature-compensated strain-gauge transducers and digital signal filtering to maintain stability under dynamic load conditions, making it suitable for gravimetric addition protocols, batch-wise reagent dosing, and continuous mass tracking during dissolution or reaction monitoring.
Key Features
- Integrated architecture combining industrial-grade magnetic stirring and precision weighing in one compact unit—eliminates alignment errors and spatial constraints associated with separate devices.
- Dual-zone control panel: left section dedicated to weighing functions (tare memory, net/gross mode, upper/lower limit alarms), right section for stirring parameters (speed, timer, direction).
- High-torque stirring motor delivering stable rotation across the full speed range (60–1400 rpm), optimized for low-shear dispersion in volumes up to 100 L of aqueous media.
- Weighing system certified to OIML R76 Class III specifications, offering 0.01 kg resolution and ±0.2 kg repeatability under static and quasi-dynamic loading conditions.
- Programmable alarm logic: configurable upper-limit (addition ceiling) and lower-limit (depletion threshold) alerts with audible and visual indicators—supports GLP-compliant process documentation.
- Stainless-steel housing with IP54-rated enclosure for resistance to chemical splashes and ambient dust; compliant with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards.
Sample Compatibility & Compliance
The MYP16 accommodates standard laboratory vessels—including polypropylene, borosilicate glass, and stainless-steel containers—up to 300 mm in diameter and 450 mm in height. It supports non-magnetic and paramagnetic vessel materials provided magnetic coupling efficiency remains ≥85% (verified per ASTM D445 methodology). For regulatory traceability, the weighing module provides audit-ready calibration logs, tare history, and alarm event timestamps. The system meets requirements for routine use in GMP-aligned environments where weight-based process steps are defined in SOPs (e.g., USP , ISO/IEC 17025:2017 Clause 6.4). Optional NIST-traceable calibration certificate available upon request.
Software & Data Management
While the MYP16 operates as a stand-alone instrument, its RS-232 serial interface enables bidirectional communication with external PCs or LIMS platforms using ASCII-based command protocol. Data export includes timestamped weight readings (kg), speed setpoints (rpm), elapsed time (min), and alarm status flags. All internal events—including tare actions, limit triggers, and power-on self-test results—are stored in non-volatile memory with retention exceeding 10,000 entries. The system supports FDA 21 CFR Part 11-compliant configurations when paired with validated third-party software for electronic signatures, role-based access control, and audit trail generation.
Applications
- Pharmaceutical formulation development: gravimetric preparation of bulk excipient blends prior to wet granulation or direct compression.
- Chemical synthesis scale-up: controlled reagent addition into large-volume reactors while monitoring cumulative mass gain to ensure stoichiometric accuracy.
- Quality control labs: dissolution testing of extended-release tablets where vessel mass changes correlate directly with solute release kinetics.
- Academic research: kinetic studies involving polymerization or precipitation reactions requiring simultaneous agitation and mass balance tracking.
- Food & beverage R&D: viscosity-modifier dispersion trials where hydration rate is inferred from real-time weight stabilization profiles.
FAQ
What is the maximum vessel height supported by the MYP16?
The unit accommodates vessels up to 450 mm in height, provided the base diameter does not exceed 300 mm and the vessel material permits sufficient magnetic coupling.
Does the MYP16 support continuous data logging without external software?
No—it retains event logs internally but requires RS-232 connection and host software for continuous streaming or CSV export.
Is the weighing system factory-calibrated, and can it be recalibrated onsite?
Yes, each unit ships with factory calibration verified against 20 kg and 100 kg test masses; users may perform intermediate verification using certified weights, though full recalibration requires authorized service personnel.
Can the MYP16 operate in fume hoods or controlled humidity environments?
It is rated IP54 and suitable for standard lab environments; however, prolonged exposure to >80% RH or corrosive vapors is not recommended without supplemental environmental shielding.
Is there a version with higher capacity than the standard MYP16?
Yes—the MYP16-300 variant offers 500 kg weighing capacity and 300 L stirring volume, designed for custom OEM integration and pilot-plant applications.
