LAUDA Varioshake VS 30 O Orbital Shaker

Overview

The LAUDA Varioshake VS 30 O is a high-performance orbital shaker engineered for demanding life science and bioengineering applications requiring uniform, reproducible agitation of large-volume or multi-vessel samples. Designed and manufactured in Germany, it operates on the principle of orbital motion—where the platform traces a circular path with a fixed 32 mm diameter—ensuring gentle yet effective mixing across the entire surface area. This motion minimizes shear stress on sensitive biological samples such as cell cultures, microbial suspensions, and immunoassay plates while maintaining consistent kinetic energy transfer. Its robust mechanical architecture—including a balanced AC motor with overload protection, four-point support rods with axial rings, and precision-machined drive mechanics—guarantees speed stability independent of load variation, making it suitable for unattended, continuous operation over extended periods.

Key Features

• Orbital shaking motion with precisely controlled 32 mm amplitude, optimized for homogeneous suspension without vortexing or splashing
• Digital LC display interface enabling direct setting and real-time monitoring of both setpoint and actual rotational frequency (20–250 rpm) in 1.0 rpm increments
• Programmable timer with resolution down to 1 minute and maximum span of 99.9 hours; continuous mode available via dedicated toggle
• Heavy-duty platform constructed from electrogalvanized steel with powder-coated finish, measuring 676 × 540 mm—accommodating standard multi-well plates, flasks up to 5 L, and custom trays
• Integrated mass-balancing system and low-noise vibration-dampening design ensure operational stability and minimal acoustic emission (<55 dB(A) at 1 m)
• Thermally stable housing (electrogalvanized + powder-coated steel) rated for ambient operation between 10 °C and 50 °C
• Optional RS-232 interface supports remote parameter control and data logging when integrated into laboratory automation workflows
• Non-slip black rubber mat (accessory A000041) provides secure sample retention; compatible with cut-to-size customization

Sample Compatibility & Compliance

The VS 30 O accommodates diverse vessel formats including Erlenmeyer flasks (up to 5 L), culture bottles, deep-well microplates, and custom bioreactor vessels—provided total mass does not exceed 30 kg. Its open-platform configuration allows flexible integration with incubator chambers or environmental enclosures. The device complies with IEC 61000-6-3 (EMC emission standards) and IEC 61000-6-2 (immunity), and meets CE marking requirements under the EU Machinery Directive 2006/42/EC. While not intrinsically rated for use inside CO₂ incubators, it is routinely deployed in ISO Class 5–7 cleanroom-adjacent labs and GLP-compliant QC environments where traceable, repeatable agitation is essential for assay reproducibility per ISO/IEC 17025 guidelines.

Software & Data Management

As a standalone benchtop instrument, the VS 30 O does not include embedded software but offers hardware-level interoperability via its optional RS-232 port. When connected to external controllers or LIMS-compatible middleware, users can log timestamped frequency and runtime data, enabling audit trails aligned with FDA 21 CFR Part 11 requirements for electronic records. Firmware updates are performed via manufacturer-provided utilities; no cloud connectivity or proprietary cloud services are implemented. All operational parameters—including elapsed time, current rpm, and error codes—are retained on the LC display during power interruption and restored upon restart.

Applications

• Cell culture maintenance and subculturing in suspension-adapted lines (e.g., CHO, Sf9, hybridoma)
• Microbial growth kinetics studies under aerobic conditions using baffled flasks
• Antibody-antigen binding assays requiring uniform plate agitation prior to ELISA readout
• Buffer equilibration and reagent homogenization for chromatography system preparation
• Enzyme activity profiling where temperature-independent mixing consistency is critical
• Bioprocess development workflows involving parallel small-scale bioreactor screening

FAQ

Is the VS 30 O suitable for use inside a CO₂ incubator?

No—the unit is designed for ambient lab environments only and is not rated for humidified, elevated-CO₂, or temperature-controlled chamber integration.
What is the tolerance for speed deviation across the full 20–250 rpm range?

Speed accuracy is ±1 rpm at all settings, verified under nominal load (≤30 kg) and stable ambient conditions (23 ± 2 °C).
Can multiple platforms be stacked or synchronized?

The VS 30 O is a single-platform system; LAUDA does not offer mechanical or electronic synchronization for multi-unit arrays.
Does the shaker include calibration documentation?

Factory calibration certificates are provided upon request and include verification of frequency output, timer accuracy, and amplitude compliance per internal QA protocol QM-LAB-047.
Are replacement parts like motors or display modules available through LAUDA service channels?

Yes—original spare parts, including the AC motor assembly (P/N VS30-MOT-01), LC module (P/N VS30-DISP-02), and support rod kits (P/N VS30-SUP-03), are supported for ≥10 years post-manufacture.
