Overview
The DLAB SK-R1807-S LED Digital Rocker Shaker is a compact, microprocessor-controlled laboratory shaker engineered for consistent, low-shear rocking motion in life science and clinical applications. It operates on the principle of unidirectional sinusoidal rocking—achieving controlled angular displacement (±3.5°, total 7° peak-to-peak) about a fixed horizontal axis—to facilitate gentle mixing, hybridization, staining, washing, and incubation of samples in tubes, Petri dishes, blotting trays, and microplates. Unlike orbital or vortex shakers, rocker shakers minimize bubble formation and shear stress, making them ideal for delicate biological assays such as Southern/Northern/Western blotting, ELISA plate washing, cell culture maintenance, and antibody incubation. Its brushless DC motor ensures stable speed output across the full 10–80 rpm range without mechanical wear or electromagnetic interference, supporting long-term unattended operation under GLP-compliant lab conditions.
Key Features
- Brushless DC motor drive delivering quiet operation (20,000 hours MTBF)
- LED digital display for real-time monitoring of both speed (rpm) and remaining timer duration with ±1% speed accuracy
- Dual operating modes: programmable timed operation (1 minute to 19 hours 59 minutes) and continuous run mode
- Fixed single-platform design with non-slip silicone-coated surface; accommodates standard blotting trays (up to 290 × 290 mm), multi-well plates, and conical tubes up to 50 mL
- Universal voltage input (100–240 V AC, 50/60 Hz) enables global deployment without external transformers
- Compact footprint (294 × 348 × 123 mm) optimized for benchtop use in biosafety cabinets, cold rooms, and shared core facilities
- IP20-rated enclosure suitable for dry, non-corrosive laboratory environments (IEC 60529 compliant)
Sample Compatibility & Compliance
The SK-R1807-S supports a broad range of sample containers including glass and plastic Petri dishes, gel electrophoresis trays, immunoblotting cassettes, 6–96-well microplates, and centrifuge tubes (up to 50 mL). Its 7° rocking angle provides sufficient fluid agitation while preventing splashing or foaming—critical for nucleic acid hybridization and protein binding kinetics. The unit meets CE marking requirements for electrical safety (EN 61010-1:2010) and electromagnetic compatibility (EN 61326-1:2013). Though not temperature-controlled, its stable thermal design allows safe operation within ambient lab conditions (5–40 °C, ≤80% RH), aligning with ISO/IEC 17025 general environmental specifications for testing laboratories.
Software & Data Management
As a standalone analog-digital hybrid instrument, the SK-R1807-S does not incorporate embedded software or data logging capabilities. All operational parameters are set and monitored via front-panel LED interface only. However, its deterministic timing circuitry and calibrated motor control ensure repeatable protocol execution—essential for SOP-driven workflows in QA/QC labs. For auditability, users may document settings manually or integrate the device into validated processes requiring traceable parameter recording per FDA 21 CFR Part 11 Annex 11 principles (e.g., through external electronic lab notebooks or LIMS entries).
Applications
- Nucleic acid and protein blotting (pre-hybridization, hybridization, and post-hybridization washes)
- Immunostaining and antigen-antibody incubation in histology and IHC workflows
- Gel staining and destaining (Coomassie, silver, SYBR Safe)
- Cell suspension maintenance during short-term incubation or transport
- Reagent mixing in diagnostic assay development and validation
- Environmental microbiology sample homogenization prior to filtration or plating
FAQ
Is the SK-R1807-S suitable for use inside a CO₂ incubator?
No—it lacks environmental sealing and temperature regulation; operation is limited to ambient laboratory conditions.
Can multiple platforms be added to this model?
No—the SK-R1807-S features a single fixed platform; multi-tier configurations require alternative models such as the SK-O1807 series.
Does it support external triggering or RS-232/USB connectivity?
No—this is a manually operated device with no digital communication interfaces.
What is the maximum recommended load for optimal performance?
2 kg distributed evenly across the platform; exceeding this may affect speed stability and rocking uniformity.
How often does the motor require maintenance?
The brushless DC motor is maintenance-free under normal operating conditions; no lubrication or brush replacement is required throughout its service life.
