Overview
The Titan RM-80D Orbital Shaker is a compact, benchtop orbital shaker engineered for consistent, low-shear mixing in life science laboratories. It operates on the principle of circular orbital motion—where the platform rotates around a fixed central axis with a 20 mm orbital diameter—generating gentle yet effective agitation ideal for cell culture flasks, Petri dishes, multiwell plates, and sample tubes. Unlike reciprocating or vortex shakers, orbital motion minimizes foaming and shear stress on sensitive biological samples, supporting aerobic microbial growth, suspension cell propagation, reagent homogenization, and immunoassay incubation protocols. Its robust aluminum-alloy chassis, brushless DC motor, and silicone-damped feet ensure mechanical stability and low-noise operation across extended runtime cycles.
Key Features
- Adjustable speed control (20–80 rpm) with ±1 rpm repeatability, calibrated via internal tachometric feedback for long-term consistency.
- Precise digital timer (1 minute to 23 hours 59 minutes) with auto-shutdown and memory retention after power interruption.
- Orbital motion platform with 20 mm diameter displacement—optimized for compatibility with standard Erlenmeyer flasks (up to 2 L), tissue culture dishes, and 96-well microplates.
- Brushless DC motor delivering maintenance-free operation, thermal overload protection, and operational lifetime exceeding 20,000 hours.
- Non-slip rubber mat surface with integrated edge lip to prevent vessel displacement during high-speed operation.
- Front-panel LED display with intuitive button interface; no external software or PC connection required for basic operation.
Sample Compatibility & Compliance
The RM-80D accommodates a broad range of common labware without adapters: round-bottom and flat-bottom flasks (50 mL–2 L), Petri dishes (up to 150 mm), deep-well plates, centrifuge tubes (15–50 mL), and PCR strip tubes. Load capacity is rated at 3 kg evenly distributed across the platform. 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 classified cleanrooms (ISO Class 5 or higher), its sealed motor housing and absence of lubricant leakage make it suitable for ISO Class 7/8 environments under routine GLP-aligned workflows.
Software & Data Management
The RM-80D operates as a standalone instrument with no embedded data logging or network connectivity. All operational parameters—including set speed, elapsed time, and remaining timer duration—are displayed in real time on the dual-digit LED screen. For laboratories requiring audit-ready records, integration with external environmental monitoring systems (e.g., Vaisala viewLinc or DeltaTRAK) can be achieved via optional analog voltage output (0–5 V) using third-party signal converters. Though not natively 21 CFR Part 11 compliant, the device supports manual logbook documentation aligned with GLP and ISO/IEC 17025 quality management frameworks when used within validated SOPs.
Applications
- Maintenance of aerobic bacterial and yeast cultures in shake flasks for bioprocess development.
- Homogenization of immunoassay reagents, ELISA coating buffers, and antibody dilutions prior to plate loading.
- Cell suspension mixing during passaging and cryopreservation workflows.
- Extraction and solubilization of proteins or nucleic acids from solid tissues under mild agitation.
- Environmental microbiology: serial dilution preparation and enrichment culture agitation.
- Quality control testing in pharmaceutical manufacturing for dissolution uniformity checks (per USP <711> guidance).
FAQ
Is the RM-80D suitable for incubator integration?
Yes—the unit operates continuously at ambient temperatures up to 40°C and has a maximum surface temperature rise of <3°C above ambient under full-load conditions, making it compatible with most CO₂ incubators equipped with external mounting brackets or shelf-mounted configurations.
Can I use this shaker for viscous solutions like agarose or methylcellulose?
It is recommended for low-to-medium viscosity applications (<500 mPa·s). For highly viscous gels or dense suspensions, reduce speed to 30–45 rpm and verify mixing uniformity empirically using dye-tracer studies.
Does the RM-80D support external triggering or remote start/stop?
No—this model lacks digital I/O ports or RS-232/USB interfaces. Remote control requires integration via programmable logic controllers (PLCs) using its optional analog output signal.
What maintenance does the RM-80D require?
Annual inspection of platform leveling and motor mount integrity is advised. No lubrication or belt replacement is needed due to the brushless motor architecture. Wipe exterior surfaces with 70% ethanol; avoid solvent exposure to control panel seals.
