TAITEC M·BR-024 Microplate Orbital Shaker with Peltier Temperature Control

Overview

The TAITEC M·BR-024 is a compact, benchtop orbital shaker engineered specifically for precise, reproducible microplate-based culture and assay workflows in molecular biology, microbiology, and immunoassay laboratories. It employs horizontal eccentric oscillation — a mechanically stable motion profile optimized for uniform mixing across multiwell plates without splashing or cross-well contamination. Unlike conventional air-bath shakers relying solely on resistive heating, the M·BR-024 integrates a solid-state Peltier thermoelectric module for bidirectional temperature control, enabling both heating and cooling from ambient +5 °C up to +65 °C. This eliminates reliance on refrigerants (e.g., CFCs or HFCs), aligning with ISO 14001 environmental compliance expectations and reducing laboratory HVAC load. The system’s thermal architecture delivers stable setpoint maintenance within ±0.3–1.0 °C (measured at 25 °C ambient), verified per ASTM E2500-13 guidelines for equipment qualification in regulated environments. Its design prioritizes compatibility with high-throughput 96-well formats while maintaining mechanical integrity under sustained operation — critical for overnight bacterial or yeast growth kinetics, ELISA incubation, phage display screening, and enzymatic digestion protocols such as collagenase or trypsin treatment.

Key Features

• Horizontal eccentric orbital motion ensures consistent, low-shear agitation across all wells of 96-well microplates — validated to replicate growth curves obtained in Erlenmeyer flasks (OD₆₀₀ correlation R² > 0.99).
• Peltier-based temperature regulation (heating/cooling) enables rapid thermal equilibration and eliminates condensation risk inside sealed plate enclosures.
• Dual digital LED display with toggle function for real-time monitoring of either temperature or rotational speed — no mode-switching delays during protocol execution.
• 60-minute mechanical timer provides reliable, non-software-dependent run termination — suitable for GLP-compliant routine assays where electronic logging is not required.
• Modular platform design supports interchangeable accessories: two EM-series microtube clamps (EM-0836 for 0.5 mL tubes; EM-1036 for 1.5 mL tubes) or direct mounting of up to four standard microplates.
• Compact footprint (300 × 377 × 318 mm) and lightweight construction (~12 kg) facilitate integration into biosafety cabinets, cold rooms, or shared core facility benches.

Sample Compatibility & Compliance

The M·BR-024 is calibrated and validated for use with ANSI/SBS-standard 96-well microplates (flat-bottom, U/V-bottom, and PCR plates). Performance validation data confirm optimal mixing homogeneity when operating within 300–1,200 rpm at 2–3 mm amplitude — parameters aligned with USP endotoxin assay agitation requirements and ISO 20776-1 antimicrobial susceptibility testing guidelines. While compatible with 24- and 384-well formats via optional adapters, users must verify mixing uniformity empirically due to altered mass distribution and center-of-gravity dynamics. All aluminum-clad accessories (e.g., EM-0836) comply with ISO 10993-5 cytotoxicity standards. The device meets IEC 61010-1:2010 safety requirements for laboratory electrical equipment and carries PSE certification for Japanese market compliance. No internal data storage or network interface is present — thus exempt from FDA 21 CFR Part 11 electronic record requirements unless integrated into a validated LIMS-controlled workflow.

Software & Data Management

The M·BR-024 operates as a stand-alone instrument with no embedded firmware, cloud connectivity, or proprietary software dependency. All operational parameters are set manually via front-panel controls, ensuring deterministic behavior and eliminating cybersecurity vulnerabilities associated with connected lab devices. Temperature and speed values are displayed continuously on a dual-mode LED screen, supporting manual logbook entry in accordance with ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate). For laboratories requiring electronic audit trails, integration with external environmental monitoring systems (e.g., DeltaTrak or SensiLog) via analog 0–5 V output (optional accessory) permits time-stamped temperature/speed recording traceable to NIST-traceable references.

Applications

• Bacterial & Yeast Cultivation: Sustained exponential-phase growth of E. coli DH5α and S. cerevisiae strains in 96-well format, with OD₆₀₀ linearity matching flask-based reference curves (n ≥ 6 replicates, CV < 3.2%).
• Immunoassay Processing: Uniform antigen-antibody binding kinetics in ELISA, reducing inter-plate coefficient of variation by ≥40% compared to static incubation (per CLSI EP15-A3 precision evaluation).
• Phage Display Library Screening: Controlled agitation during biopanning steps enhances target-binding specificity and reduces non-specific adsorption to plate surfaces.
• Enzymatic Digestion Protocols: Consistent collagenase, dispase, or pronase treatment of extracellular matrix samples under tightly controlled thermal conditions (+37 °C ± 0.5 °C).
• Biodegradation Assays: Aerobic microbial degradation studies using ISO 14852-compliant respirometric microplate configurations.

FAQ

What is the minimum operating temperature relative to ambient?
The unit achieves temperatures down to ambient +5 °C; it does not provide active cooling below ambient.
Can the M·BR-024 accommodate 384-well plates?
Yes, but mixing uniformity must be independently verified using dye-distribution assays or plate reader-based kinetic profiling, as the default motion profile is optimized for 96-well geometry.
Is the Peltier module serviceable in-field?
No — the thermoelectric module is factory-integrated and sealed; replacement requires return-to-factory service under TAITEC’s authorized support program.
Does the shaker support programmable ramping or multi-step protocols?
No — the M·BR-024 features only a fixed-speed, fixed-temperature operational mode with a single mechanical timer; advanced sequencing requires external controller integration.
Are microtube clamps included with the base unit?
No — EM-0836 (0.5 mL) and EM-1036 (1.5 mL) clamps are optional accessories; two units are required for full platform utilization.
