Overview
The Titan TOS-200 Orbital Shaker is an engineered platform for consistent, low-shear mixing of biological and chemical samples in tubes, flasks, and microplates. Utilizing a precise eccentric drive mechanism, it generates uniform circular motion—commonly referred to as orbital shaking—with a fixed 20 mm orbit diameter. This motion promotes efficient oxygen transfer and suspension homogeneity without inducing excessive shear stress, making it particularly suitable for cell culture maintenance, bacterial growth, enzyme assays, and reagent preparation in academic, pharmaceutical, and quality control laboratories.
Key Features
- Stable orbital motion with ±1 rpm speed accuracy across the full 50–250 rpm range, ensuring reproducible agitation conditions between experiments.
- Programmable digital timer supporting intervals from 1 minute up to 99 hours and 59 minutes, enabling unattended overnight or multi-day incubation protocols.
- Single-platform design with non-slip rubber mat surface and universal clamping compatibility for Erlenmeyer flasks (up to 2 L), test tubes, and standard microtiter plates (96-well).
- Brushless DC motor ensures long service life, minimal heat generation, and silent operation—critical for shared lab environments and temperature-sensitive applications.
- Robust steel frame with powder-coated finish provides structural integrity and resistance to common laboratory solvents and cleaning agents.
- Front-panel LED display with intuitive push-button interface allows real-time monitoring and adjustment of speed and time without software dependency.
Sample Compatibility & Compliance
The TOS-200 accommodates a wide range of vessel types and volumes, including conical flasks (50 mL to 2 L), centrifuge tubes (15–50 mL), and flat-bottom or U-bottom microplates. Its 20 mm orbit supports optimal aeration for aerobic microbial cultures while minimizing foam formation in protein-rich media. The unit complies with IEC 61010-1:2010 safety standards for laboratory electrical equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. While not certified for use in regulated GMP environments out-of-the-box, its stable performance and traceable operational parameters support integration into GLP-compliant workflows when paired with documented calibration procedures and user-defined SOPs.
Software & Data Management
The TOS-200 operates as a standalone instrument without proprietary software or PC connectivity. All settings are retained in non-volatile memory during power interruption, preserving protocol continuity. For labs requiring audit trails or electronic recordkeeping, external data loggers compatible with analog 0–5 V or 4–20 mA output signals (available via optional analog interface module) can be deployed to capture real-time speed and runtime data. When integrated into larger laboratory information management systems (LIMS), the device supports manual entry of shaker parameters into batch records aligned with FDA 21 CFR Part 11 principles—provided users implement appropriate procedural controls for data integrity and operator authentication.
Applications
- Maintenance of suspension mammalian and insect cell lines under non-adherent conditions.
- Bacterial and yeast cultivation for plasmid amplification, protein expression, and metabolic studies.
- Antibody-antigen binding assays requiring gentle, continuous mixing to enhance reaction kinetics.
- Solubility testing and dissolution profiling of solid dosage forms in early-stage formulation development.
- Preparation of homogeneous calibration standards and QC reference materials across clinical chemistry and environmental testing labs.
- Supporting ASTM D7890-21 (Standard Practice for Laboratory Shaking of Soil and Sediment Samples) for environmental sample extraction protocols.
FAQ
Is the TOS-200 compatible with incubator chambers?
Yes—the unit’s compact footprint (320 × 320 × 160 mm) and low thermal output allow safe operation inside standard CO₂ or ambient-temperature incubators, provided adequate ventilation and clearance around the motor housing are maintained.
Can I calibrate the speed and timer independently?
Speed calibration is performed using an external tachometer against the displayed rpm value; timer verification requires a certified stopwatch or digital timer. Calibration certificates are not supplied by default but may be generated internally per ISO/IEC 17025 guidelines.
Does the shaker support stacking or multi-tier configurations?
No—the TOS-200 is designed as a single-platform unit. Stacking is not recommended due to vibration coupling and potential instability; however, multiple units may be installed side-by-side on reinforced benchtops with ≥50 mm spacing for thermal and acoustic isolation.
What maintenance is required for long-term reliability?
Routine inspection of the eccentric drive coupling and platform mounting bolts every 6 months is advised. No lubrication is required; the brushless motor eliminates carbon brush wear and associated particulate generation.
