Overview
The DLAB SK-R30D-E is a dual-deck rocking platform shaker engineered for gentle, uniform mixing of liquid samples in life science and clinical laboratory workflows. It operates on the principle of controlled angular oscillation—rocking motion generated by a brushless DC motor driving two independently supported decks at a fixed tilt angle of 40 ± 3°. This geometry ensures consistent fluid displacement across vessels without splashing or foaming, making it especially suitable for cell suspension, antibody incubation, blotting washes, hybridization steps, and low-shear sample homogenization. Unlike orbital or vortex shakers, the SK-R30D-E delivers laminar, gravity-assisted mixing ideal for fragile biological matrices such as primary cell cultures, tissue lysates, and immunoassay plates. Its continuous-operation design supports unattended overnight protocols, while its compact footprint (405 × 160 × 160 mm) enables integration into cold rooms, biosafety cabinets, and benchtop incubators.
Key Features
- Dual independent rocking decks—each accommodating up to 16 × 5–10 mL centrifuge tubes or 6 × 50 mL conical tubes when fitted with compatible silicone mats.
- Precisely calibrated rocking angle of 40 ± 3°, optimized for efficient lateral fluid movement while minimizing bubble formation and sample denaturation.
- Brushless DC motor ensures silent, vibration-damped operation with zero maintenance requirements and extended service life (>20,000 hours MTBF).
- Wide-input voltage compatibility (100–240 V AC, 50/60 Hz) enables stable performance across global laboratory power infrastructures—including variable-voltage environments common in mobile labs or field deployment scenarios.
- Thermostatically regulated operating range of 5–40 °C allows integration with environmental chambers or use in temperature-sensitive applications such as enzyme-linked assays and nucleic acid hybridization.
- Low power consumption (15 W) supports energy-efficient lab operations and reduces thermal load on adjacent instrumentation.
Sample Compatibility & Compliance
The SK-R30D-E accommodates standard laboratory consumables including polypropylene and glass tubes (5–50 mL), microcentrifuge tubes (with optional adapter kits), and flat-bottom multiwell plates (e.g., 96-well formats). Each deck supports a maximum load of 1 kg, ensuring mechanical stability even with dense buffer solutions or viscous reagents. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. While not certified for GLP/GMP-regulated production environments, its reproducible rocking parameters (±0.5 rpm speed stability, <1% angle deviation over 100-hour duty cycle) support documented method validation under ISO/IEC 17025-accredited quality systems.
Software & Data Management
The SK-R30D-E is a stand-alone analog-controlled instrument with no embedded firmware, touchscreen interface, or digital connectivity. All operational parameters—including speed (0–30 rpm) and deck engagement—are adjusted manually via front-panel rotary dials. This architecture eliminates software validation overhead and aligns with laboratories maintaining legacy SOPs or adhering to strict cyber-security policies prohibiting networked peripherals. For traceability, users may record setpoints and run durations in electronic lab notebooks (ELNs) compliant with FDA 21 CFR Part 11 when paired with time-stamped audit logs.
Applications
- Western blot and ELISA membrane washing steps requiring uniform buffer exchange without agitation-induced membrane damage.
- Long-duration hybridization of DNA/RNA probes under controlled temperature conditions.
- Suspension of adherent cells post-trypsinization prior to counting or plating.
- Equilibration of chromatography columns and affinity resins during binding/wash cycles.
- Pre-analytical processing of clinical specimens—including serum separation, antigen retrieval, and immunochemical staining protocols.
- Quality control testing of diagnostic reagents where shear-sensitive proteins must remain structurally intact.
FAQ
Does the SK-R30D-E support programmable timing or interval-based operation?
No—it operates exclusively in continuous mode without timer functionality. Users must implement external timing controls (e.g., wall clocks, lab timers, or ELN-based scheduling) for defined incubation durations.
Can both decks operate at different speeds or angles?
No—the two decks are mechanically coupled and share identical rocking parameters. Independent deck control is not supported.
Is the unit suitable for use inside a CO₂ incubator?
Yes, provided ambient humidity remains ≤80% RH and internal temperature stays within the 5–40 °C operating range. Confirm compatibility with incubator manufacturer regarding off-gas emissions and condensation management.
What certifications does the SK-R30D-E carry for international shipment?
It bears CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and conforms to RoHS 2011/65/EU. UL/cUL certification is not available.
Are replacement silicone mats available for purchase separately?
Yes—DLAB offers standardized silicone mat kits (part number SK-MAT-01) designed specifically for 5–10 mL tube arrays and 50 mL conical tube configurations.
