Overview
The Caframo BDC3030220U1 Universal Overhead Stirrer is an industrial-grade, electronically controlled laboratory stirrer engineered for precision mixing across a broad spectrum of viscosities and batch sizes—from low-viscosity buffers and aqueous media to high-viscosity gels, emulsions, and suspensions. Utilizing a brushless DC motor and an integrated two-speed electronic gearbox, the system delivers consistent torque delivery and speed stability under variable load conditions—critical for reproducible process development, quality control, and scale-up studies. Designed for continuous-duty operation in regulated laboratory environments, the BDC3030220U1 features a fully enclosed cast aluminum housing that ensures thermal stability, electromagnetic compatibility (EMC), and resistance to chemical splashes and particulate ingress. Its dual-voltage configuration (220–240 V, 50/60 Hz) supports seamless deployment in EU, UK, and APAC laboratories without voltage conversion hardware.
Key Features
- Brushless DC motor with integrated thermal protection and zero maintenance requirements—eliminates carbon brush wear and associated downtime.
- Two-speed electronic gearbox enabling optimized performance: high-torque mode (20–600 rpm, up to 341 N·cm) for viscous materials; high-speed mode (600–3000 rpm, up to 68 N·cm) for low-viscosity homogenization.
- Digital LED display showing real-time rotational speed (±1 rpm or ±1% of reading) and torque (±12 N·cm or ±5% of reading), supporting traceable process monitoring.
- Through-shaft design with 10 mm maximum chuck capacity and integrated chuck guard—meets IEC 61000-3-2 harmonic emission standards and reduces mechanical hazard per ISO 13857.
- Robust cast aluminum chassis (5 kg net weight) provides vibration damping and structural rigidity during extended operation at elevated torque loads.
- CSA-certified for use in both U.S. and Canadian laboratories—compliant with CAN/CSA-C22.2 No. 61010-1 and UL 61010-1 safety standards for electrical equipment for measurement, control, and laboratory use.
Sample Compatibility & Compliance
The BDC3030220U1 accommodates standard laboratory vessels ranging from 50 mL beakers to 60 L jacketed reactors. Its torque and speed profiles are validated for Newtonian and pseudoplastic fluids up to 50,000 mPa·s—covering applications in pharmaceutical formulation (e.g., hydrogel synthesis per USP ), bioprocess media preparation (per ASTM D1200), and polymer dispersion (per ISO 2557-2). The unit operates within ambient conditions of 5–40 °C and ≤80% RH non-condensing, making it suitable for cold-room and controlled-environment labs. All electrical interfaces meet CE marking requirements for EMC (EN 61326-1) and low-voltage directive (2014/35/EU). Optional accessories—including PTFE-coated impellers, clamping stands, and reactor brackets—are designed to maintain GMP-aligned installation integrity per FDA 21 CFR Part 11 Annex 11 data governance expectations.
Software & Data Management
While the BDC3030220U1 operates as a standalone instrument, its digital speed/torque readouts support manual logging into ELN systems compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). For automated data capture, optional analog output (0–10 V or 4–20 mA) can be interfaced with SCADA or LIMS platforms via third-party signal conditioning modules. All firmware updates are delivered via secure USB firmware loader—maintaining audit trail integrity and version control in accordance with ISO/IEC 17025:2017 clause 7.7.2. No embedded wireless connectivity is included, minimizing cybersecurity exposure in regulated QC/QA workflows.
Applications
- Preparation of cell culture media and buffer solutions requiring shear-sensitive component preservation.
- Homogenization of pharmaceutical ointments and topical suspensions under GMP-compliant mixing protocols.
- Dispersion of nanoparticles and pigment slurries in R&D-scale coating formulations.
- Viscosity-dependent reaction initiation in synthetic chemistry (e.g., polycondensation kinetics monitoring).
- Continuous blending validation for process analytical technology (PAT) initiatives aligned with ICH Q8(R2) and Q9 frameworks.
FAQ
Is the BDC3030220U1 compatible with GLP/GMP documentation requirements?
Yes—the device’s digital torque/speed readouts, CSA certification, and stable mechanical architecture support documented procedure execution and equipment qualification (IQ/OQ) per FDA guidance and EU Annex 15.
Can the stirrer be integrated into a temperature-controlled reactor system?
Yes—its through-shaft design and 5–40 °C operational envelope allow direct coupling with jacketed vessels and PID-controlled heating/cooling circulators.
What impeller types are recommended for high-viscosity applications?
Anchor, helical ribbon, and double-helix impellers with shaft diameters ≤10 mm are validated for use; Caframo recommends PTFE- or Hastelloy-coated variants for corrosive media.
Does the unit include overload protection?
Yes—motor current limiting, thermal cutoff, and automatic stall detection prevent damage during viscosity spikes or mechanical binding.
Is remote start/stop functionality available?
Not natively—but dry-contact terminals (optional accessory kit) enable integration with external PLC or footswitch controls for hands-free operation.
