Overview
The Scientific Industries Mini-300 Orbital-Genie Shaker is a compact, high-stability orbital shaker engineered for consistent, low-vibration mixing in life science laboratories. It operates on the principle of orbital motion—where the platform rotates in a circular path with a fixed 19 mm orbit diameter—generating gentle yet effective agitation ideal for cell culture flasks, test tubes, microplates, and small-volume reaction vessels. Designed for ambient-temperature applications, the Mini-300 delivers precise speed control without integrated heating or cooling, making it suitable for routine incubation-independent protocols such as reagent homogenization, bacterial suspension preparation, ELISA plate washing support, and sample equilibration prior to downstream analysis. Its robust aluminum housing and optimized mass distribution (10.25 kg) minimize lateral displacement during operation—even at maximum 300 rpm—eliminating the need for anchoring or external stabilization hardware.
Key Features
- Precisely adjustable speed control across a wide range of 35–300 rpm, calibrated via an analog dial with visual feedback for repeatable setting recall.
- Stable 19 mm orbital motion ensures uniform mixing energy distribution across the platform surface, minimizing vortexing artifacts and shear-sensitive cell damage.
- Integrated anti-slip base and balanced center-of-gravity design prevent device migration on standard lab benches—no mounting brackets or adhesive pads required under normal use conditions.
- Modular accessory compatibility: accepts interchangeable platforms including stainless-steel sample racks (SI-M1501), universal clamp rods (SI-M1501), beaker stands (SI-M1601), and 460 × 460 mm non-slip blue rubber mats (SI-M1701).
- CE-certified electrical architecture compliant with IEC 61010-1 safety standards for laboratory equipment; designed for continuous-duty operation in ISO 15190-compliant environments.
Sample Compatibility & Compliance
The Mini-300 supports diverse vessel formats up to 2 L capacity when used with appropriate fixtures—including Erlenmeyer flasks (up to 1 L), culture bottles, multi-well plates (6–96-well), centrifuge tubes (15–50 mL), and glass vials. Its single-platform configuration allows rapid reconfiguration between workflows without recalibration. The shaker meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not certified for GMP manufacturing environments, its mechanical repeatability and documented performance parameters align with GLP documentation practices for method validation in academic and preclinical research settings.
Software & Data Management
The Mini-300 is a standalone analog instrument with no embedded microprocessor or digital interface. Speed settings are manually selected and maintained without software dependency—ensuring operational reliability, immunity to firmware failure, and full compatibility with regulated environments where electronic audit trails are either unnecessary or managed externally. Users may log operating parameters (rpm, duration, vessel type) in paper-based or LIMS-integrated electronic notebooks per institutional SOPs. For laboratories requiring traceable operation records, integration with time-stamped environmental monitoring systems or external programmable timers is supported via standard AC power control.
Applications
- Pre-incubation mixing of microbial cultures in shake flasks for OD600 standardization.
- Uniform dispersion of antibodies, antigens, or nanoparticles in buffer matrices prior to immunoassay setup.
- Supporting solvent extraction protocols in natural product isolation workflows.
- Maintaining suspension integrity during long-term storage of yeast or algal cultures at room temperature.
- Facilitating passive mixing in enzymatic digestion steps where thermal activation is performed separately.
FAQ
Is the Mini-300 compatible with incubators or cold rooms?
Yes—the unit operates reliably within ambient temperature ranges of 10–35 °C and relative humidity ≤80% non-condensing. Its lack of internal thermal regulation makes it suitable for placement inside standard CO2 incubators (with adequate airflow clearance) or refrigerated cabinets, provided electrical outlets meet local safety codes.
Does it support timer functionality?
No—the Mini-300 does not include a built-in timer. External mechanical or digital timers (e.g., DIN-rail mounted or plug-in models) may be used upstream of the power supply to enforce defined run durations.
What maintenance is required?
Annual inspection of drive belt tension and platform bearing smoothness is recommended. No lubrication is required; wipe-down with 70% ethanol suffices for routine decontamination. Calibration verification against a handheld tachometer is advised every six months for critical applications.
Can multiple vessels with different volumes be mixed simultaneously?
Yes—provided total load remains within the platform’s dynamic balance limits (max. 5 kg distributed evenly). Use of clamps, racks, or rubber mats is strongly recommended to secure heterogeneous vessel sets and maintain orbital fidelity.
Is regulatory documentation available for audit purposes?
CE Declaration of Conformity, electrical schematics, and mechanical drawings are available upon request from Scientific Industries’ technical support team for quality system audits under ISO 9001 or FDA 21 CFR Part 11-aligned documentation frameworks.
