Overview
The Titan LM-80D Long-Axis Orbital Shaker is an engineered platform for uniform, low-shear mixing of multiple samples in flasks, tubes, and microplates under controlled orbital motion. Designed with a horizontal long-axis drive mechanism, it generates consistent circular motion (orbital diameter: 25 mm) across the entire platform surface—minimizing vortex formation while maximizing suspension homogeneity for sensitive biological suspensions, cell cultures, and reagent preparations. Unlike vertical reciprocating shakers or vortex mixers, the LM-80D’s extended axis architecture ensures mechanical stability at lower rotational speeds (20–80 rpm), reducing sample splashing and thermal drift during prolonged incubation-mimicking protocols. It is not intended for high-speed centrifugation, agitation under pressure, or sterile chamber integration; rather, it serves as a dedicated benchtop solution for routine mixing tasks in molecular biology labs, quality control environments, and academic teaching facilities.
Key Features
- Long-axis orbital drive system delivering uniform motion across full platform area—no dead zones or edge attenuation
- Digital timer with precision resolution (1-minute increments) supporting programmable run durations from 1 minute to 23 hours and 59 minutes
- Adjustable speed control (20–80 rpm) via calibrated rotary encoder; speed stability maintained within ±1 rpm under nominal load (≤5 kg)
- Robust aluminum alloy frame with anti-slip silicone mat surface—compatible with Erlenmeyer flasks (up to 2 L), universal racks, PCR tube holders, and standard 96-well plates
- Low-noise DC motor with thermal protection circuitry—operates at <45 dB(A) at 1 m distance, suitable for shared lab spaces
- Compact footprint (320 × 260 × 140 mm) and lightweight design (6.2 kg) for flexible placement on biosafety cabinets, cold rooms, or laminar flow hoods
Sample Compatibility & Compliance
The LM-80D accommodates common laboratory vessels without requiring custom clamps or adapters: conical flasks (50–2000 mL), test tubes (12–18 mm OD), microcentrifuge tubes (0.5–2.0 mL), and flat-bottomed microplates. Load distribution must remain balanced—maximum recommended payload is 5.0 kg with center-of-gravity deviation ≤15 mm from platform center. The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per CISPR 11 Group 1, Class B. While not certified for use in ISO Class 5 cleanrooms or GMP manufacturing suites, its construction supports GLP-aligned documentation workflows when paired with external loggers for time-stamped operation records.
Software & Data Management
The LM-80D operates as a standalone analog-digital hybrid instrument with no embedded firmware, network interface, or proprietary software. All settings are configured locally via front-panel controls; no drivers, cloud services, or USB connectivity are required. For audit-trail compliance in regulated environments (e.g., USP , FDA 21 CFR Part 11), users may integrate external data loggers (e.g., Omega OM-DAQPRO-5300) to record runtime, speed, and elapsed duration. Calibration verification can be performed using NIST-traceable tachometers; Titan provides a factory calibration certificate upon request (non-certified by default). No password protection, user roles, or electronic signature functionality is included—consistent with its role as a general-purpose utility device.
Applications
- Resuspension of lyophilized reagents and bacterial pellets prior to downstream analysis
- Equilibration of immunoassay plates during ELISA blocking and washing steps
- Uniform mixing of agarose gels pre-casting and post-solidification
- Low-intensity agitation of mammalian cell cultures in T-flasks during transient transfection protocols
- Standardization of solvent-based extractions (e.g., phenol-chloroform) where phase separation must remain undisturbed
- Teaching laboratories: demonstration of orbital kinetics, viscosity-dependent mixing behavior, and timer-based experimental replication
FAQ
Is the LM-80D suitable for use inside a CO₂ incubator?
No. It is rated for ambient operating conditions only (10–40 °C, 20–80% RH non-condensing). Internal humidity and elevated temperature will compromise motor longevity and electronic integrity.
Can I mount it vertically or at an angle?
No. The unit must be placed horizontally on a level, vibration-dampened surface. Tilting or wall-mounting invalidates mechanical alignment and voids warranty.
Does it support continuous operation beyond 24 hours?
The timer resets after 23 h 59 min; however, manual restart is permitted. For unattended multi-day runs, external programmable timers or PLC integration is recommended.
What maintenance is required?
Wipe down with 70% ethanol after each use; inspect silicone mat for wear every 6 months; verify speed accuracy annually using a handheld tachometer.
Is there a CE or UL mark on the device?
It carries a CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD); UL listing is not available. Regulatory documentation is supplied with shipment.
