TAITEC Personal-11•SDN Combination Water Bath Shaker

Overview

The TAITEC Personal-11•SDN Combination Water Bath Shaker is an engineered solution for precise temperature-controlled agitation in life science laboratories. It integrates a reciprocating shaking mechanism with a thermostatically regulated water bath chamber—enabling simultaneous control of thermal environment and mechanical mixing. Based on proven Couette-flow-inspired oscillation dynamics and PID-controlled immersion heating/cooling, the system maintains stable thermal homogeneity across the liquid medium while delivering reproducible orbital or linear motion. Designed for applications requiring both physiological temperature fidelity and consistent kinetic energy transfer—such as microbial growth kinetics, enzymatic assays, nucleic acid hybridization, and sample homogenization—the Personal-11•SDN meets core operational requirements for GLP-compliant bioprocess development and academic research workflows.

Key Features

• Modular dual-function architecture: Independent yet synchronized control of water bath temperature and reciprocating oscillation parameters
• Continuously adjustable amplitude (10–40 mm) and speed (20–160 rpm), enabling optimization for viscous media, low-volume samples, or shear-sensitive cells
• PID-based temperature regulation with high-resolution NTC sensors; achieves ±0.1 °C to ±0.3 °C uniformity across the bath volume (tested per ASTM E2798)
• Corrosion-resistant stainless-steel water bath tank with integrated overflow protection and easy-drain valve
• Digital microprocessor controller with LED display, real-time parameter monitoring, and non-volatile memory for up to 10 user-defined protocols
• Low-noise DC motor drive with brushless design ensures long-term reliability and minimal vibration transmission to adjacent instrumentation
• Compliant with IEC 61010-1 safety standards for laboratory equipment; CE-marked for use in EU-regulated environments

Sample Compatibility & Compliance

The Personal-11•SDN accommodates standard laboratory vessels including Erlenmeyer flasks (50–2000 mL), test tubes (12–50 mm diameter), deep-well microplates, and custom reaction chambers. Its open-bath configuration supports direct immersion of containers without lid interference, while optional clamping fixtures ensure secure positioning during high-amplitude operation. The system operates within ISO 17025-aligned environmental conditions and is routinely validated for use in QC/QA labs adhering to USP <1058> Analytical Instrument Qualification guidelines. Temperature stability data are traceable to NIST-certified reference thermometers, supporting audit readiness under FDA 21 CFR Part 11 when paired with compliant data logging software.

Software & Data Management

While the base unit features standalone operation via front-panel controls, optional RS-232/USB interface enables connection to PC-based acquisition systems. TAITEC’s optional LogView Pro software provides time-stamped logging of temperature, speed, amplitude, and runtime—generating CSV-exportable records with embedded metadata (operator ID, protocol name, timestamp). Audit trails include user login history and parameter change logs, satisfying ALCOA+ principles for data integrity. When deployed in regulated environments, the system can be configured to meet electronic record retention requirements per Annex 11 (EU GMP) and 21 CFR Part 11 through role-based access control and digital signature integration.

Applications

• Escherichia coli and yeast culture expansion under controlled aeration and thermal profiles
• Kinetic studies of enzyme activity (e.g., β-galactosidase, horseradish peroxidase) requiring uniform substrate mixing at defined temperatures
• Western blot membrane hybridization and pre-hybridization wash steps
• Pre-analytical processing of asbestos or fibrous particulate suspensions per EPA Method 600/R-93/116
• Cell lysis and protein extraction from bacterial pellets using detergent-based buffers
• Standardization of dissolution testing for pharmaceutical formulations (aligned with USP <711>)

FAQ

What is the maximum load capacity per platform?
The standard shaking platform supports up to 3 kg distributed load; water bath tray capacity is limited by fluid volume (max 8 L) and vessel height clearance (≤180 mm).
Can the system operate unattended overnight?
Yes—programmable timer supports durations up to 99 hours, 59 minutes; auto-shutdown and overtemperature cut-off provide fail-safe operation.
Is calibration documentation available?
TAITEC supplies factory calibration certificates for temperature and speed sensors; on-site IQ/OQ/PQ validation support is available through authorized service partners.
Does the unit support external temperature probes?
An optional PT100 probe port allows insertion of a secondary sensor directly into the sample vessel for process-critical temperature verification.
How is maintenance performed?
Routine tasks include periodic descaling of the water bath (using 5% acetic acid), inspection of O-rings, and verification of motor coupling alignment—procedures detailed in the bilingual (EN/JP) service manual included with shipment.
