DLAB SK-O180-Pro LCD Digital Orbital Shaker

Overview

The DLAB SK-O180-Pro LCD Digital Orbital Shaker is an engineered solution for precise, reproducible orbital agitation in life science laboratories. Designed around a robust brushless DC motor and precision-machined eccentric drive mechanism, it delivers consistent 4 mm orbital motion across its single-platform configuration—ideal for applications requiring gentle yet effective mixing of biological samples, cell cultures, immunoassays, and reagent preparation. Unlike reciprocating or vortex shakers, the SK-O180-Pro employs true circular orbital motion, minimizing shear stress on sensitive cells and ensuring uniform suspension without splashing or foaming. Its compact footprint (300 × 340 × 100 mm) and IP20-rated enclosure support integration into biosafety cabinets, cold rooms, and standard benchtop environments operating between 5–40 °C and up to 80% relative humidity.

Key Features

• Dual independent LCD displays—one for real-time speed (rpm), one for elapsed or remaining timer duration—enabling simultaneous monitoring without menu navigation.
• Brushless DC motor architecture ensures maintenance-free operation, low electromagnetic interference, and stable speed control across the full 100–800 rpm range with ±1 rpm repeatability under load.
• Integrated safety logic prevents unintended acceleration: automatic speed cutoff activates if platform imbalance exceeds tolerance or if lid access is detected during operation.
• Programmable timing from 1 minute to 19 hours 59 minutes supports both short-term incubation steps and overnight protocols without manual intervention.
• RS232 serial interface enables bidirectional communication with host PCs; compatible with DLAB’s free Shaker PC software for remote parameter setting, real-time speed/timer visualization, and exportable CSV log files.
• Modular accessory system—including universal clamps, flask holders (50–1000 mL), petri dish racks, and microplate adapters—ensures compatibility with ISO-standard labware without mechanical adaptation.

Sample Compatibility & Compliance

The SK-O180-Pro accommodates a wide range of vessel formats commonly used in molecular biology, microbiology, and quality control labs—including Erlenmeyer flasks (50–1000 mL), culture dishes (up to 150 mm diameter), multiwell plates (6–96-well), and centrifuge tubes (15–50 mL). Its 2.5 kg maximum load capacity (inclusive of fixtures) allows concurrent processing of multiple sample sets while maintaining mechanical stability at high speeds. The device complies with IEC 61010-1:2010 for laboratory electrical equipment safety and meets EMC requirements per EN 61326-1:2013. While not certified for GMP cleanroom use (IP20 rating limits dust ingress protection), its non-porous ABS+PC housing resists common disinfectants (70% ethanol, 0.5% sodium hypochlorite) and supports routine decontamination in GLP-aligned workflows.

Software & Data Management

DLAB’s proprietary Shaker PC software (v2.1+, Windows 10/11 compatible) provides a validated interface for instrument control and data traceability. Users can configure ramp-up profiles, define multi-step programs (e.g., 300 rpm × 2 h → 500 rpm × 1 h), and visualize live speed/time curves with timestamped logging. All parameter changes are recorded with operator ID and system timestamp—supporting audit-ready documentation for internal SOPs and external inspections aligned with FDA 21 CFR Part 11 principles (electronic signature capability available via optional domain-authenticated login). Export functions generate time-stamped .csv files suitable for LIMS integration or statistical process analysis in JMP or Minitab.

Applications

• Microbial growth enhancement in liquid media (e.g., E. coli, yeast, bacilli) under controlled temperature conditions.
• Antibody-antigen binding kinetics in ELISA plate washing and incubation stages.
• Suspension of mammalian or insect cell lines prior to passaging or transfection.
• Homogenization of tissue lysates and protein extraction buffers to minimize aggregation.
• Pre-analytical sample preparation for HPLC, mass spectrometry, and NGS library construction where particulate resuspension is critical.
• Environmental microbiology workflows including waterborne pathogen enrichment and soil extract agitation.

FAQ

Is the SK-O180-Pro suitable for use inside a CO₂ incubator?

No—the unit is rated for ambient operation only (5–40 °C, ≤80% RH) and lacks the corrosion-resistant seals or gas-tight housing required for humidified CO₂ environments.
Can the RS232 interface be used with modern laptops lacking serial ports?

Yes—USB-to-RS232 adapters compliant with FTDI chipset drivers are fully supported; DLAB provides connection pinout documentation and terminal configuration guidelines.
Does the shaker retain settings after power interruption?

No—it resets to default speed (300 rpm) and timer-off state upon restart; user-defined programs must be reloaded via front panel or PC software.
What is the warranty coverage for the brushless motor?

DLAB provides a 24-month limited warranty covering motor failure due to material or workmanship defects, excluding damage from improper loading, chemical exposure, or unauthorized modification.
Are third-party accessories (e.g., custom plate holders) mechanically compatible?

Only DLAB-certified fixtures are guaranteed for dynamic balance and platform integrity; non-OEM adapters may compromise speed accuracy or trigger safety cutoffs above 600 rpm.
