DRETOP TRB Series Orbital Shaker

Overview

The DRETOP TRB Series Orbital Shaker is an engineered platform for scalable, reproducible liquid mixing in research and production environments. Designed according to orbital (circular) motion principles—where the tray rotates around a fixed horizontal axis with controlled eccentricity—the system generates uniform, low-shear agitation ideal for aerobic microbial culture, suspension cell propagation, enzyme kinetics assays, and reagent homogenization. Unlike reciprocating or vortex shakers, orbital motion minimizes splashing and foaming while maximizing oxygen transfer efficiency—critical for high-density bacterial fermentation, yeast propagation, and mammalian suspension cultures. The TRB Series supports both laboratory-scale screening and pilot-scale process development, conforming to fundamental mechanical design standards for stability, thermal management, and electromagnetic compatibility (EMC) per IEC 61326-1.

Key Features

• High-contrast backlit LCD display with intuitive touch-key interface: real-time monitoring of setpoint frequency, actual RPM, elapsed time, and operational status;
• Precision-machined 3D eccentric cam shaft drive system: ensures smooth acceleration from rest to target speed (0–300 rpm), eliminating torque shock and reducing mechanical stress on flasks and closures;
• Non-volatile parameter memory with encryption: retains user-defined settings—including frequency, runtime, and tray assignment—even after power interruption or system reset;
• Dual-tray configuration option (“II” models): enables independent operation of two trays at identical or differential speeds (synchronized or asynchronous mode), supporting parallel experiments under varied conditions;
• Structural rigidity and vibration isolation: heavy-gauge steel frame with reinforced base and anti-slip rubber feet minimize transmission of oscillatory energy to adjacent instrumentation;
• Compliance-ready design: no internal batteries or wireless modules; all firmware updates performed via secure USB interface—facilitating audit trails required under GLP and GMP-aligned workflows.

Sample Compatibility & Compliance

The TRB Series accommodates standard Erlenmeyer flasks (150–1000 mL), baffled flasks, test tubes, and multi-well plates using interchangeable universal clamps or custom silicone mat inserts. All tray surfaces are electropolished stainless steel (AISI 304), resistant to autoclaving, alcohol disinfection, and common laboratory solvents. The device meets CE marking requirements for electrical safety (EN 61010-1) and electromagnetic immunity (EN 61326-1). While not certified for use in classified hazardous locations (e.g., ATEX Zone 1), it is suitable for ISO Class 7/8 cleanroom-adjacent laboratories when operated with appropriate gowning and airflow protocols. Documentation includes factory calibration certificates traceable to NIM (National Institute of Metrology, China) standards.

Software & Data Management

The TRB Series operates as a standalone instrument without proprietary software dependency. All operational parameters are configured locally via the front-panel interface. For integration into automated lab environments, optional RS-232 or USB-to-serial adapters support ASCII command protocol (e.g., “FREQ=220”, “START”, “STOP”) compatible with LabVIEW™, Python-based control scripts, or LIMS middleware. Audit log functionality records timestamped events—including power-on, parameter changes, and stop commands—in non-erasable internal memory. This supports 21 CFR Part 11 compliance when paired with validated electronic signature systems and networked data archival solutions.

Applications

• Biopharmaceutical R&D: Seed train expansion, media optimization studies, and clone selection across E. coli, S. cerevisiae, CHO, and HEK293 suspension cultures;
• Quality control microbiology: Growth promotion testing of culture media per USP <61> and ISO 11133;
• Environmental analysis: BOD incubation, nutrient solution mixing for phytoplankton assays, and soil slurry homogenization;
• Food science: Starter culture propagation, fermentation kinetics modeling, and allergen extraction validation;
• Academic teaching labs: Hands-on instruction in microbial growth dynamics, Michaelis–Menten enzyme assays, and mass-transfer coefficient determination.

FAQ

Is the TRB Series suitable for sterile applications?
Yes—when used with sterile flasks, filtered air inlets, and laminar flow hood placement. The unit itself is not autoclavable but supports SIP-compatible accessories.
Can amplitude be adjusted beyond 26 mm?
A 35 mm amplitude variant is available upon request and requires factory recalibration; contact technical support for lead time and validation documentation.
What maintenance is required?
Annual inspection of eccentric cam lubrication and belt tension (if applicable); no routine calibration is needed unless subjected to mechanical impact or environmental extremes.
Does “II” in model number indicate dual independent control?
Yes—“II” models feature two electrically isolated drive circuits, enabling simultaneous but non-identical operation of both trays without cross-interference.
Are spare trays and clamps available as accessories?
Yes—standard trays (stainless steel, perforated or solid), universal flask clamps (for 125–1000 mL), and silicone mat kits are stocked and ship within 3 business days from Shanghai warehouse.
