Overview
The Labquake 415220 360° Rotational Shaker is an engineered solution for gentle, uniform end-over-end mixing of liquid-phase biological samples in centrifuge tubes. Unlike orbital or reciprocating shakers, this device employs a true 360° continuous rotational principle—based on controlled coaxial shaft rotation—to induce consistent tumbling motion without shear-intensive agitation. This mechanism ensures homogenization while preserving cell integrity, minimizing foaming, and preventing sediment compaction—critical for applications involving bacterial cultures, immunoassays, hybridization reactions, and low-sedimentation-rate suspensions. Designed for benchtop use in molecular biology labs, QC environments, and academic research facilities, the unit operates with a robust brushless DC motor and precision gear train to deliver stable, repeatable motion across its full 22–70 cycle/min range. Its compact footprint (47 × 15 × 12 cm) and lightweight construction (3 kg) support flexible placement in biosafety cabinets, cold rooms, or multi-instrument workstations.
Key Features
- True 360° continuous rotational motion—no dead zones or directional reversal, ensuring uniform sample exposure to gravitational vector changes
- Fixed-clamp tube holder design accommodating 14 centrifuge tubes (10–19 mm diameter), optimized for secure retention during extended operation
- Motor-driven speed control with calibrated dial interface; base motor speed fixed at 8 rpm, adjustable output frequency via mechanical gear reduction (22–70 cycles/min)
- Hot-swap capability: centrifuge tubes may be inserted or removed during active operation without interrupting rotation—enabling sequential sample loading and real-time protocol adjustments
- Low-power consumption (≤15 W typical) and thermally stable housing suitable for unattended operation up to 72 hours
- CE-compliant electrical architecture with reinforced insulation and overcurrent protection; compatible with standard 220 V, 50/60 Hz laboratory power infrastructure
Sample Compatibility & Compliance
The Labquake 415220 supports standard polypropylene and glass centrifuge tubes ranging from 10 to 19 mm outer diameter—including common formats such as 15 mL conical, 10 mL round-bottom, and microcentrifuge-compatible adaptors (with optional accessory kits). It is validated for use with aqueous buffers, serum-containing media, viscous glycerol stocks, and low-conductivity solvents (conductivity <5 mS/cm). The device complies with IEC 61010-1:2010 for safety requirements of electrical equipment for measurement, control, and laboratory use. While not certified for sterile processing, its smooth, non-porous ABS housing and minimal crevice design facilitate routine disinfection using 70% ethanol or 0.5% sodium hypochlorite solutions—supporting GLP-aligned cleaning validation protocols.
Software & Data Management
This model operates as a stand-alone analog instrument without embedded firmware, touchscreen interface, or digital connectivity. All operational parameters are manually set and mechanically maintained—eliminating software dependencies, calibration drift, or cybersecurity vulnerabilities associated with IoT-enabled lab hardware. Time-based experiments rely on external timers or laboratory scheduling systems. For audit-trail compliance in regulated environments (e.g., ISO 17025 or FDA 21 CFR Part 11), users may integrate the shaker into documented SOPs specifying start/stop timestamps, load configuration, and environmental conditions (ambient temperature/humidity logs). No proprietary drivers, SDKs, or cloud services are required or supported.
Applications
- Hybridization of nucleic acid probes on membrane blots under low-shear conditions
- Equilibration of antibody-antigen binding reactions in ELISA plate pre-incubation workflows
- Maintenance of aerobic bacterial cultures in static-phase resuspension protocols
- Uniform dispersion of magnetic beads in automated extraction cartridges prior to separation
- Rehydration and gentle reconstitution of lyophilized protein standards
- Long-duration diffusion-controlled dissolution testing of insoluble compounds in pharmacokinetic screening
FAQ
Is the Labquake 415220 suitable for use inside a CO₂ incubator?
No—this unit is rated for ambient operation only (10–40°C, ≤80% RH non-condensing) and lacks ingress protection or incubator-grade electrical certification.
Can it accommodate 50 mL conical tubes?
Not natively; the fixed clamp geometry is dimensioned for 10–19 mm OD tubes. Custom fixture adapters are not offered by the manufacturer.
Does the shaker provide programmable timing or automatic shut-off?
No—the device has no internal timer or auto-stop function; external timing devices must be used for duration control.
What maintenance is required for long-term reliability?
Annual inspection of clamp retention torque and gear train lubricity is recommended; no scheduled replacement parts exist beyond standard electrical safety checks per institutional facility guidelines.
