DLAB SK-D3309-Pro 3D Orbital Shaker

Overview

The DLAB SK-D3309-Pro 3D Orbital Shaker is an engineered solution for gentle yet effective sample agitation in life science and clinical laboratories. Unlike conventional orbital or linear shakers, this unit employs a true three-dimensional motion profile—combining orbital rotation with controlled axial tilt (7°)—to generate uniform, low-shear mixing across the entire sample surface. This kinematic design ensures consistent reagent penetration during staining, washing, hybridization, and immunoblotting procedures without compromising delicate biological structures such as gels, membranes, or adherent cell monolayers. Its robust aluminum-alloy chassis and precision-machined drive mechanism support stable operation under variable load conditions up to 5 kg, making it suitable for high-throughput workflows involving multi-well plates, Petri dishes, flasks, and blotting cassettes.

Key Features

• Genuine 3D motion architecture with synchronized orbital rotation and fixed 7° tilt angle—optimized for uniform agitation of flat-format samples including SDS-PAGE gels, nitrocellulose/PVDF membranes, and microtiter plates.
• LCD interface displaying real-time speed (10–70 rpm) and remaining timer duration simultaneously—enabling precise protocol adherence without manual intervention.
• Dual-mode operation: programmable timed cycles (1–1199 minutes) or uninterrupted continuous run—supporting both standardized assays and extended incubation protocols.
• Non-slip silicone-coated platform with integrated retention grooves—minimizing lateral displacement of vessels during operation, even at higher speeds or with partially filled containers.
• Universal switching power supply (100–240 VAC, 50/60 Hz) compliant with international laboratory infrastructure standards—eliminating need for voltage converters in global deployments.
• IP21-rated enclosure providing protection against vertically falling solid objects and limited ingress of moisture—suitable for standard ISO Class 7/8 clean bench environments and general-purpose lab spaces.

Sample Compatibility & Compliance

The SK-D3309-Pro accommodates a broad range of vessel formats, including 10 × 10 cm gel trays, 15–50 mL conical tubes, 6–96-well microplates, hybridization bottles (up to 500 mL), and standard Western blot cassettes. Its low-vibration motor assembly and balanced drive train meet mechanical stability requirements outlined in ISO 13485 Annex A for equipment used in diagnostic assay development. While not certified for GMP manufacturing environments per se, its traceable timer function, non-volatile parameter memory, and absence of user-accessible calibration adjustments align with GLP documentation practices for method validation studies. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets RoHS Directive 2011/65/EU material restrictions.

Software & Data Management

This model operates as a standalone instrument with no embedded firmware-based data logging or network connectivity. All operational parameters—including speed setpoint, elapsed time, and mode selection—are retained in volatile memory only during active use and reset upon power cycle. For audit-trail compliance in regulated settings (e.g., clinical research labs operating under FDA 21 CFR Part 11 guidelines), external documentation via electronic lab notebooks (ELNs) or paper-based logbooks is recommended. No proprietary software drivers or USB interfaces are required; setup and monitoring rely exclusively on front-panel controls and visual feedback.

Applications

• Electrophoretic gel processing: Coomassie/silver staining and destaining with minimized background and enhanced band resolution.
• Molecular hybridization: Uniform probe distribution during Southern/Northern blotting and FISH procedures.
• Immunodetection workflows: Consistent antibody binding and wash efficiency in ELISA, dot blot, and Western blot protocols.
• Cell culture maintenance: Gentle agitation of suspension cultures or post-trypsinization resuspension steps where shear sensitivity is critical.
• Antigen-antibody complex formation: Accelerated immuno-precipitation kinetics without denaturation or aggregation artifacts.

FAQ

Is the SK-D3309-Pro compatible with vacuum-sealed hybridization bags?
Yes—the low-acceleration 3D motion profile prevents bag rupture while ensuring full reagent contact across the membrane surface.
Can the shaker operate unattended overnight?
Yes, provided ambient temperature remains within 5–40 °C and relative humidity does not exceed 80%. The 1199-minute maximum timer supports most overnight protocols.
Does the unit include interchangeable platforms?
No—this model features a fixed, integrated platform with universal anti-slip surface geometry optimized for common labware dimensions.
What maintenance is required for long-term reliability?
Periodic inspection of the rubber isolation feet and cleaning of the platform surface with isopropyl alcohol; no lubrication or internal servicing is specified by the manufacturer.
Is speed calibration traceable to national standards?
No—the device lacks built-in calibration capability or certificate-of-conformance documentation; users requiring metrological traceability should employ external tachometric verification.
