TAITEC NR-5100 Large-Capacity Reciprocating Shaker and Dual-Layer NR-5100 Shaking Platform

Overview

The TAITEC NR-5100 is a heavy-duty, large-capacity reciprocating shaker engineered for industrial-scale microbial cultivation in pharmaceutical and biotechnology production. Unlike orbital or rotary shakers, the NR-5100 employs a precisely controlled linear reciprocating motion—critical for high-aeration cultures of filamentous organisms such as Penicillium and Streptomyces species used in antibiotic synthesis. Its 70 mm amplitude—selectable via mechanical adjustment—generates superior oxygen transfer rates (k_La) in large-volume vessels, enabling efficient aerobic growth in 500 mL to 5 L Erlenmeyer flasks without foam destabilization or shear-induced hyphal fragmentation. The system operates without integrated temperature control and is intended for installation within climate-stabilized rooms (e.g., ±0.5 °C controlled environments), ensuring compliance with upstream bioprocess requirements under cGMP and ISO 13485 frameworks.

Key Features

• High-amplitude reciprocating drive mechanism optimized for filamentous fungal and actinomycete cultivation
• Three-step amplitude selection (25 / 50 / 70 mm) — factory-configured at 70 mm for antibiotic production applications
• Single-layer NR-5100 accommodates up to 65 × 500 mL Erlenmeyer flasks or 59 × 500 mL round-bottom flasks; dual-layer configuration doubles capacity to 130 × 500 mL flasks or 118 × 500 mL round-bottom flasks
• Robust cast-iron frame and reinforced platform (1200 × 860 mm) supporting ≥36 kg per layer under dynamic load conditions
• Integrated safety architecture including leakage current interrupter, thermal-overload protected induction motor, and redundant fuse protection
• Anchor-mounting capability (100 mm depth) for vibration isolation in shared laboratory or pilot-plant facilities

Sample Compatibility & Compliance

The NR-5100 supports standardized microbiological vessel formats across USP General Chapter <1043> and JP XVIII specifications. Compatible accessories include TAITEC’s MT-12086 platform and CF/SF-series clamps (CF-0500, CF-1000, SF-0500, etc.), validated for secure retention of flasks up to 5 L during sustained operation at 250 rpm. All clamp geometries comply with ASTM D4169 performance criteria for mechanical stability under cyclic loading. The shaker meets IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. While not intrinsically temperature-controlled, its design enables seamless integration into HVAC-regulated cleanrooms compliant with ISO 14644-1 Class 7/8 environments and FDA 21 CFR Part 11–aligned process documentation systems when paired with external environmental loggers.

Software & Data Management

The NR-5100 operates as a hardware-controlled analog system with no embedded microprocessor or digital interface. Speed and amplitude are set manually via front-panel dials and mechanical linkage—ensuring deterministic repeatability and eliminating firmware-related drift or cybersecurity exposure. For traceability in regulated environments, users integrate external programmable logic controllers (PLCs) or data acquisition systems (e.g., National Instruments CompactRIO) to record runtime parameters (speed, duration, power draw) with timestamped audit trails. This architecture aligns with Annex 11 (EU GMP) and ALCOA+ principles by decoupling operational control from data recording—supporting independent validation of both subsystems.

Applications

• Industrial-scale antibiotic fermentation using Aspergillus, Penicillium, and Streptomyces strains requiring high k_La and low-shear agitation
• Recombinant protein expression in E. coli and Pichia pastoris cultures where flask-based scalability precedes bioreactor transfer
• Secondary metabolite screening in natural product discovery pipelines
• Seed train expansion for mammalian cell culture processes where shake-flask consistency informs bioreactor inoculum density
• Method development for USP <1225> verification of aerobic growth kinetics under defined mechanical stress conditions

FAQ

Does the NR-5100 include temperature control?
No. It is a dedicated shaking platform designed for use inside externally regulated incubation chambers or climate-controlled rooms.
Can amplitude be adjusted by the user?
Amplitude switching (25 / 50 / 70 mm) requires qualified technician service due to mechanical linkage recalibration; field modification voids warranty and compromises safety certification.
Is the dual-layer NR-5100 suitable for stacked flask configurations?
Yes—each layer operates independently with identical motion profiles; however, lower-layer clearance restricts use of tall vessels (e.g., >300 mm height flasks) on the bottom tier.
What electrical infrastructure is required?
A dedicated 100 V AC, 2 A circuit with grounded outlet and GFCI protection is mandatory; voltage fluctuations exceeding ±5% require an active line conditioner.
How is mechanical validation performed?
Per ISO 20957-4, users conduct periodic amplitude verification using calibrated laser displacement sensors and rotational speed measurement via non-contact tachometer, with records retained per GLP Annex 13.
