DLAB SK-O330-Pro LCD Digital Orbital Shaker

Overview

The DLAB SK-O330-Pro LCD Digital Orbital Shaker is an engineered platform for precise, reproducible orbital motion in life science laboratories. Designed around the Couette-type orbital oscillation principle—where a circular drive mechanism imparts uniform tangential motion to the platform—the instrument delivers consistent mixing, suspension, and aeration across diverse biological samples. Unlike reciprocating or vortex shakers, orbital motion minimizes shear stress on delicate cells and microbial cultures while ensuring homogeneous distribution of nutrients, gases, and reagents. The SK-O330-Pro operates exclusively at ambient temperature (5–40 °C), making it suitable for benchtop applications adjacent to incubators or within controlled laboratory environments. Its compact footprint (370 × 420 × 100 mm) and IP21-rated enclosure support integration into ISO Class 5–8 clean benches, biosafety cabinets, and GLP-compliant QC labs where spatial efficiency and electrical safety are prioritized.

Key Features

• Independent dual-LCD display: One screen shows real-time rotational speed (rpm), the other displays remaining timer duration—enabling simultaneous monitoring without mode switching.
• Brushless DC motor architecture: Eliminates carbon brush wear, ensures stable torque delivery across the full 100–500 rpm range, and supports >20,000 hours of maintenance-free operation under standard load conditions.
• Programmable timing function: Adjustable from 1 minute to 19 hours and 59 minutes; supports both continuous run and auto-stop modes with audible end-of-cycle alert.
• Over-speed protection circuitry: Automatically halts operation if rotational speed exceeds user-defined thresholds or deviates beyond ±5 rpm tolerance for >3 seconds—preventing sample spillage and mechanical overload.
• Modular platform compatibility: Accepts interchangeable stainless-steel, rubber-coated, or perforated platforms (sold separately) to accommodate Petri dishes, Erlenmeyer flasks (up to 2 L), multi-well plates, and tube racks—ensuring secure retention at all speeds.
• RS232 serial interface: Enables bidirectional communication with host PCs for remote parameter configuration, real-time speed/time logging, and firmware updates.

Sample Compatibility & Compliance

The SK-O330-Pro accommodates standard labware including 35–150 mm Petri dishes, 50–2000 mL Erlenmeyer flasks, 96-well microplates, and centrifuge tube holders (15–50 mL). Its 7.5 kg maximum payload includes mass of clamps and platform—verified per ASTM D4169-22 handling stability protocols. While the unit itself does not carry CE, UL, or UKCA certification, its design adheres to IEC 61010-1:2010 safety requirements for laboratory electrical equipment. When deployed in regulated environments (e.g., pharmaceutical QC labs), users may document operational parameters—including speed calibration traceability, timer accuracy (±0.5%), and thermal drift (<±0.3 °C/h at 25 °C ambient)—to satisfy internal SOPs aligned with USP Analytical Instrument Qualification guidelines.

Software & Data Management

DLAB provides the Shaker PC Control Software (v3.2+, Windows 10/11 compatible) as a no-cost download. The application supports full remote control of speed setpoint, timer activation/deactivation, and real-time graphical plotting of rpm vs. time. All session data—including start/stop timestamps, average speed deviation, and total runtime—is exported in CSV format for audit-ready recordkeeping. The software implements local data caching and supports manual export triggers, meeting baseline requirements for ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) when used in non-GxP contexts. For Part 11–compliant deployments, third-party LIMS or ELN integrations can be achieved via ASCII command protocol documentation (available upon request from DLAB Technical Support).

Applications

• Microbial culture agitation during aerobic growth phase (E. coli, yeast, Bacillus spp.)
• Antibiotic susceptibility testing using broth microdilution in 96-well plates
• Cell detachment and resuspension prior to flow cytometry or passaging
• Antigen-antibody binding kinetics in immunoassay development
• Solubility screening of small-molecule compounds in aqueous/organic solvent systems
• Pre-analytical homogenization of clinical specimens (e.g., whole blood, sputum) prior to nucleic acid extraction

FAQ

Is the SK-O330-Pro compatible with CO₂ incubators?

No—the unit is not rated for humidified or elevated-CO₂ environments. It is intended for ambient-temperature benchtop use only. For incubated shaking, consider DLAB’s IS-RDS series or third-party incubator-compatible orbital shakers.
Does the RS232 interface support USB-to-serial adapters?

Yes—standard FTDI- or CH340-based USB-to-RS232 adapters are fully functional with Shaker PC Software when appropriate drivers are installed.
Can speed calibration be performed in-house?

Yes—DLAB supplies a calibration certificate traceable to NIM (National Institute of Metrology, China) and recommends annual verification using an optical tachometer compliant with ISO 5348:2019.
What is the warranty coverage?

DLAB provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use.
Are platform clamps included by default?

One universal spring-loaded clamp set (for 125–2000 mL flasks) is supplied standard. Additional fixtures—including microplate holders and Petri dish grids—are available as optional accessories (order codes: SK-CLAMP-PLATE, SK-CLAMP-DISH).
