LAUDA Varioshake VS 15 T Three-Dimensional Orbital Shaker

Overview

The LAUDA Varioshake VS 15 T is a precision-engineered three-dimensional orbital shaker designed for demanding life science and bioengineering applications requiring uniform, gentle, and reproducible agitation. Unlike conventional linear or circular shakers, the VS 15 T employs an optimized figure-eight motion trajectory—generated via a dynamically balanced eccentric drive mechanism—that ensures homogeneous mixing across the entire sample surface without vortexing or splashing. This 3D orbital motion enhances mass transfer, improves cell suspension homogeneity, and supports consistent aeration in microbiological cultures, enzymatic assays, and immunoassay plate incubation. Its robust architecture, low-noise operation, and load-independent speed stability make it suitable for unattended, continuous operation in regulated laboratory environments—including ISO 17025-accredited testing labs and GLP-compliant research facilities.

Key Features

• Three-dimensional orbital motion with precise 3° amplitude and digitally controlled frequency range of 2–50 rpm (0.5 rpm resolution), ensuring repeatable agitation profiles across variable loads up to 15 kg.
• Electronically regulated AC motor with integrated thermal overload protection and dynamic mass-balancing system—eliminating vibration transmission and extending mechanical service life.
• Compact footprint (480 × 487 × 160 mm) and lightweight construction (19 kg) facilitate integration into biosafety cabinets, cold rooms, and multi-instrument workstations.
• Corrosion-resistant anodized aluminum tray (450 × 450 mm) with four non-slip polymer locating pins; compatible with standard microtiter plates, flasks, tubes, and custom vessels.
• Intuitive LC display interface enabling real-time monitoring and parameter setting—including timer (1 min to 99:59 h), speed, and operational status—with optional RS-232 serial interface for external control or data logging.
• Electrogalvanized steel housing with durable powder coating provides chemical resistance and structural rigidity under routine laboratory use conditions (ambient temperature range: 10–50 °C).

Sample Compatibility & Compliance

The VS 15 T accommodates a broad spectrum of vessel formats—including 96-well plates, Erlenmeyer flasks (up to 2 L), centrifuge tubes, and custom bioreactor modules—without requiring mechanical adapters. Its low-shear orbital motion preserves sensitive cell lines, primary cultures, and protein-based reagents during extended incubation protocols. The device conforms to IEC 61010-1 safety standards for laboratory equipment and meets electromagnetic compatibility (EMC) requirements per EN 61326-1. While not intrinsically certified for hazardous locations, its design supports deployment in Class II biological safety cabinets when configured with appropriate airflow clearance. Documentation packages include CE marking declarations and RoHS compliance statements.

Software & Data Management

The shaker operates autonomously via its onboard controller; however, the optional RS-232 interface enables integration into centralized lab automation systems. When connected to validated PC-based software (e.g., LAUDA LabControl Suite or third-party SCADA platforms), users can log timestamped operational parameters—including actual speed, elapsed time, and error codes—for audit trails compliant with FDA 21 CFR Part 11 requirements. Audit-ready configuration files support version-controlled method storage and user-access permissions. No proprietary cloud dependency is required—data export is supported in CSV and XML formats for LIMS ingestion.

Applications

• Maintenance of aerobic microbial cultures in shake flasks under controlled aeration conditions.
• Uniform coating and washing steps in ELISA, Western blotting, and cell-based assay workflows.
• Suspension of stem cells and organoids during expansion and differentiation protocols.
• Buffer equilibration, antigen-antibody binding kinetics studies, and small-volume reagent mixing in drug discovery pipelines.
• Environmental microbiology sampling preparation, including soil slurry homogenization and waterborne pathogen enrichment.
• Quality control testing of diagnostic kits where consistent mechanical agitation directly impacts signal reproducibility.

FAQ

Is the VS 15 T suitable for use inside a CO₂ incubator?

No—the unit is rated for ambient operation only (10–50 °C) and is not sealed or humidity-rated for internal incubator placement. External mounting with remote tray access is recommended for controlled-atmosphere applications.
Can the oscillation amplitude be adjusted?

No—the 3° amplitude is mechanically fixed to ensure optimal orbital geometry and long-term drive train integrity. This design prioritizes repeatability over user-variable amplitude settings.
Does the shaker support GMP documentation packages?

Yes—LAUDA provides IQ/OQ documentation templates, calibration certificates traceable to national standards (DKD/DAkkS), and maintenance logs compliant with EU Annex 11 and USP analytical instrument qualification guidelines.
What is the warranty period and service coverage?

The VS 15 T carries a standard 24-month parts-and-labor warranty from date of commissioning, extendable to 36 months with annual preventive maintenance contracts performed by LAUDA-certified field engineers.
Are replacement trays or custom fixtures available?

Yes—LAUDA offers a modular accessory ecosystem including anti-slip universal trays (A000049), silicone-adhesive pads (A000041), and specialized flask clamping carriers (A000043/A000045), all designed to maintain mechanical alignment and minimize resonance-induced drift.
