WIGGENS KA11 Series Laboratory Height-Adjustable Platform

Overview

The WIGGENS KA11 Series Laboratory Height-Adjustable Platform is an engineered mechanical support system designed for precise, repeatable vertical positioning of laboratory equipment—including analytical balances, spectrophotometers, pipetting stations, and modular synthesis rigs—within controlled environments. Unlike motorized or pneumatic lifts, the KA11 series employs a manually operated, gear-driven lead-screw mechanism with integrated locking collars, ensuring static stability under load without power dependency. Its core function is to provide ergonomic height adjustment across a fixed 270 mm travel range while maintaining ±0.1 mm positional repeatability and zero drift during extended operation. The platform’s rigid stainless-steel frame (AISI 304) and precision-machined guide rails eliminate lateral play and torsional flex, making it suitable for applications requiring long-term dimensional integrity—such as GLP-compliant weighing workflows or vibration-sensitive optical alignment.

Key Features

• Stainless-steel structural frame (AISI 304) for corrosion resistance and cleanroom compatibility
• Manually actuated, self-locking lead-screw drive with dual-position locking collar for secure height retention
• 270 mm total vertical travel range with tactile, calibrated scale markings (1 mm increments)
• Four standard platform sizes: 15×15 cm, 20×20 cm, 25×25 cm, and 30×30 cm—each optimized for load distribution up to 20 kg (static)
• Variant-specific base configurations: S/T (solid top), A/L (adjustable leveling feet), and N-series (non-magnetic version for MRI-adjacent labs)
• No electrical components—compliant with intrinsically safe zones and Class I Div 2 environments
• ISO 9001-certified manufacturing process; CE-marked per Machinery Directive 2006/42/EC

Sample Compatibility & Compliance

The KA11 platform supports passive mounting of instruments with flat, rigid bases—no adhesives or clamps required. Its non-slip surface finish (Ra ≤ 0.8 µm) prevents lateral migration of devices during height adjustment. All variants meet DIN EN 1090-1 for structural steel execution class EXC2 and are validated for use in ISO 14644-1 Class 5–8 cleanrooms. For regulated laboratories, the platform’s mechanical simplicity ensures full traceability: each unit carries a unique serial number engraved on the base plate, and dimensional test reports (including parallelism deviation < 0.05 mm/m and flatness tolerance ±0.03 mm) are supplied with shipment. It complies with IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emission) standards—not as an electronic device, but as a grounded metallic structure contributing to overall lab EMI mitigation.

Software & Data Management

The KA11 Series is a purely mechanical system with no embedded electronics, firmware, or connectivity interfaces. Consequently, it requires no software installation, calibration certificates with digital signatures, or audit trails. This design eliminates cybersecurity risks and regulatory overhead associated with 21 CFR Part 11 compliance—making it ideal for legacy instrument integration and FDA-inspected facilities where “software-free” infrastructure is preferred. Documentation includes a printed Installation & Safety Manual (EN 61000-6-4 compliant), dimensional verification report, and material certification (EN 10204 3.1). Digital copies (PDF) are provided upon request with timestamped revision control.

Applications

• Ergonomic repositioning of analytical balances to align with operator height and reduce musculoskeletal strain (aligned with ISO 11228-1 guidelines)
• Vertical staging of HPLC detectors or UV-Vis cuvette holders to match optical path heights across multi-instrument setups
• Support for glovebox-integrated reactors where electrical actuators are prohibited
• Height calibration reference for laser interferometry workbenches requiring stable Z-axis offsets
• Modular lab furniture integration—compatible with WIGGENS’ WA2000 series bench frames and third-party ISO-standard mounting rails (M6 thread pattern)
• Teaching labs: used to demonstrate mechanical advantage, screw kinematics, and static load distribution principles

FAQ

Is the KA11 platform compatible with vibration isolation tables?
Yes—the base plate features four M6 threaded inserts spaced at 100 mm intervals, enabling direct bolt-down to standard optical tables and active/passive isolators.
Can it be sterilized for aseptic applications?
The AISI 304 stainless-steel construction withstands repeated ethanol wiping, VHP (vaporized hydrogen peroxide), and autoclaving at 121°C for 20 minutes—though prolonged exposure above 150°C may affect lubricant integrity in the lead screw assembly.
What is the maximum recommended load for dynamic operation?
20 kg static; for repetitive height adjustments with loaded instrumentation, WIGGENS recommends ≤12 kg to preserve long-term wear life of the bronze bushings and maintain repeatability beyond 10,000 cycles.
Are custom platform dimensions available?
Standard configurations only; however, WIGGENS offers OEM engineering consultation for volume orders (>25 units) requiring modified footprint or mounting patterns—subject to minimum order quantity and 12-week lead time.
Does the platform include leveling feet?
Only A/L variants (e.g., KA11-91B, KA11-92) feature adjustable stainless-steel leveling feet with 10 mm thread travel; S/T models require external shimming for fine horizontal alignment.
