TAITEC BR-40/41/42/43 Series Medium-Size Incubated Orbital Shaker

Overview

The TAITEC BR-40/41/42/43 Series represents a family of medium-capacity, air-jacketed incubated orbital shakers engineered for precise temperature-controlled cultivation of microorganisms, yeast, insect cells, thermophiles, and psychrophiles. These instruments operate on the principle of orbital shaking—generating uniform, low-shear circular motion with a fixed 25 mm orbit diameter—to ensure homogeneous suspension, optimal gas exchange, and consistent nutrient distribution across liquid cultures. Unlike water-jacketed systems, the air-jacketed thermal architecture delivers rapid temperature equilibration, reduced condensation risk, and improved energy efficiency while maintaining tight thermal stability (±0.3–1.0°C under controlled ambient conditions). Each model is purpose-built for distinct operational profiles: the BR-40LF supports low-temperature preservation protocols (e.g., +4°C post-culture hold), while the BR-43FH variant extends upper temperature capability to +100°C for thermophilic strain propagation. All units are manufactured in Japan under stringent quality control and comply with IEC 61010-1 safety requirements for laboratory equipment.

Key Features

• Modular door architecture: BR-40LF features a transparent top-hinged lid optimized for high-clearance access to large-volume vessels (e.g., dual 2 L flasks); BR-41/42/43 models integrate a Sharp-engineered bi-directional side-opening door system eliminating spatial constraints during installation.
• Programmable multi-step thermal and agitation control: BR-41/42/43 support up to 9-step sequential programs—each step independently configurable for temperature (±0.1°C resolution), speed (1 rpm increments), and duration (00h00m–99h59m)—including ramp-rate control for gradual thermal transitions.
• Stackable design: Units may be vertically stacked using optional STB-6070 (BR-41/42/43) or Stack Base A (BR-40LF) kits—enabling dual-platform operation within footprint-constrained labs. BR-40LF must occupy the upper position due to its cooling module layout.
• Retractable control panel (BR-41/42/43 only): Fully recessed digital interface minimizes protrusion, enhances ergonomics, and simplifies cleaning protocols in biosafety-conscious environments.
• Dual-mode oscillation: Selectable reciprocating or orbital motion on BR-40LF and BR-43 series; BR-41/42 models operate exclusively in orbital mode for maximal culture homogeneity.
• Comprehensive safety architecture: Integrated leakage current protection, overcurrent cutoff, redundant thermal fusing, programmable high/low temperature alarms, motor current limiting, refrigeration compressor overheat shutdown (BR-40LF & FL-series), and real-time sensor diagnostics.

Sample Compatibility & Compliance

The BR-Series accommodates diverse vessel geometries via interchangeable platforms—including MR-4030 spring-grid (2-layer height-adjustable), SR-4030 adhesive mat (renewable hydrophobic polymer surface), MT-4030 clamp-based platform, and specialized fixtures for tubes, centrifuge bottles, and Erlenmeyer flasks. Standard capacity includes six 500 mL flasks or one 5 L flask (BR-40LF: max two 2 L flasks). All platforms conform to ISO 8573-1 purity class 4 for particulate control in non-sterile benchtop applications. The system meets mechanical safety requirements per IEC 61010-1 Ed.3 and electromagnetic compatibility per IEC 61326-1. While not certified for GMP manufacturing, its programmable audit trail (via optional RS-232/USB data logging), parameter lockout, and calibration traceability support GLP-aligned documentation for academic, clinical, and preclinical laboratories.

Software & Data Management

Native firmware enables full local control without PC dependency. Time-stamped event logs record start/stop times, temperature deviations (>±2°C), speed fluctuations (>±5 rpm), door openings, and fault codes—retained for ≥30 days in non-volatile memory. Optional JCP-3657 external connection port supports analog voltage output (0–10 V) for integration into centralized building management systems (BMS) or SCADA networks. Data export is available via USB flash drive in CSV format compliant with LIMS ingestion standards. For regulated environments, optional software packages provide 21 CFR Part 11-compliant electronic signatures, user role-based access control, and immutable audit trails—validated for use in USP analytical instrument qualification frameworks.

Applications

• Microbial growth kinetics: Escherichia coli, Bacillus subtilis, and Pseudomonas aeruginosa cultivation under defined oxygen transfer rates (OTR) at 30–37°C.
• Low-temperature biopreservation: Automated transition from +37°C active culture to +4°C storage mode post-incubation (BR-40LF timer function).
• Thermophile propagation: BR-43FH enables sustained growth of Geobacillus stearothermophilus and Thermus aquaticus up to +100°C with continuous agitation.
• Insect and yeast cell expansion: Sf9, High Five™, and Pichia pastoris cultures benefit from low-shear orbital motion and ±0.5°C thermal precision.
• Enzyme assay preparation: Homogeneous mixing of substrate-enzyme solutions prior to spectrophotometric analysis.
• Media sterilization validation: Thermal profiling of agar-based media during pre-incubation cycles.

FAQ

What is the maximum load capacity per platform?
Each platform supports up to 7 kg total mass—including platform weight, clamps, and culture vessels—verified under static and dynamic loading per ISO 17025 mechanical testing guidelines.
Can the BR-40LF be placed on the bottom tier of a stacked configuration?
No. Due to its integrated refrigeration unit and rear exhaust layout, BR-40LF must be installed as the upper unit when stacking with BR-41/42/43 models.
Is frost formation expected during extended +4°C operation?
Yes. Continuous operation below +10°C may cause internal frost accumulation on evaporator coils. Manual defrosting every 72 operational hours is recommended to maintain specified temperature accuracy and range.
Are calibration certificates provided with shipment?
Factory calibration reports (NIST-traceable RTD and tachometer verification) are included. On-site IQ/OQ/PQ documentation support is available through TAITEC-authorized service partners.
Which platform is recommended for 50 mL conical centrifuge tubes?
The MR-4030 spring-grid platform accommodates 48 × 50 mL tubes at 45° tilt; for higher rigidity during >200 rpm operation, the MT-4030 clamp platform with AT-3518 tube rack (18 × 50 mL) is advised.
