Stainless Steel Adjustable Height Platform – Truelab Model SS-150×150

Overview

The Truelab SS-150×150 Stainless Steel Adjustable Height Platform is an engineered mechanical support solution designed for precise vertical positioning in analytical laboratories, quality control environments, and regulated R&D workflows. Unlike generic height-adjustable stands, this platform employs a dual-gear rack-and-pinion lifting mechanism—fully enclosed within the column housing—to ensure backlash-free, repeatable height increments with mechanical locking at any position between 80 mm and 320 mm. Its structural integrity derives from monolithic 304 stainless steel construction: base plate, top platform, central column, and gear housing are all fabricated from solid, non-welded or fully TIG-welded, passivated stainless steel components. This architecture eliminates galvanic corrosion risks, resists cleaning agents (including 70% ethanol, 1% sodium hypochlorite, and alkaline detergents), and maintains dimensional stability under sustained static loads up to 50 kg—making it suitable for mounting spectrophotometers, digital microscopes, weighing modules, or sample staging systems requiring long-term positional fidelity.

Key Features

• Full 304 stainless steel construction: Electropolished surfaces meet ASTM A967 for corrosion resistance and facilitate ISO 14644-1 Class 5 cleanroom-compatible cleaning protocols.
• Dual-gear rack-and-pinion drive: Provides smooth, vibration-damped height adjustment without slippage; integrated friction-locking knob secures position without drift under load.
• Load-rated platform geometry: 150 × 150 mm top surface with machined 0.05 mm flatness tolerance ensures optical and mechanical alignment stability for mounted instrumentation.
• Low-profile base design: 180 × 180 mm footprint with recessed leveling feet allows integration into confined benchtop spaces while maintaining tip-over resistance per IEC 61000-4-2 compliance guidelines.
• No-tool assembly & serviceability: Modular column assembly enables field replacement of gear sets or bushings using standard hex keys—no proprietary tools required.

Sample Compatibility & Compliance

This platform does not perform analytical measurements and therefore has no sample interaction or consumables. It serves exclusively as a passive mechanical interface between instrumentation and benchtop infrastructure. Its material composition and finish comply with FDA-recommended surface criteria for non-product-contact laboratory hardware (FDA Guidance for Industry: Process Validation, 2011). The electropolished stainless steel surface supports routine disinfection per USP Analytical Instrument Qualification protocols and meets EN 13485 requirements for devices used in GMP-regulated environments where equipment qualification documentation (IQ/OQ) is required. No electrical or pneumatic interfaces are present; no CE marking or UL certification applies, as it is classified as Class I non-electrical laboratory furniture per IEC 61010-1 Annex BB.

Software & Data Management

The Truelab SS-150×150 is a purely mechanical device with no embedded electronics, firmware, sensors, or connectivity interfaces. Consequently, it generates no telemetry, requires no software drivers, and introduces zero cybersecurity or data integrity considerations. Its use does not trigger FDA 21 CFR Part 11 requirements for electronic records or signatures. All operational parameters—including height settings, load configurations, and maintenance logs—are documented manually in laboratory notebooks or LIMS entries per GLP Annex 11 and ISO/IEC 17025:2017 clause 7.11. Calibration is not applicable; however, periodic verification of height repeatability (±0.2 mm over 10 cycles) and locking torque (≥1.8 N·m) is recommended during scheduled equipment checks.

Applications

• Vertical positioning of UV-Vis spectrophotometer cuvette holders to align optical paths across multi-instrument setups.
• Stable elevation platform for digital metallurgical microscopes performing ASTM E3-22 grain size analysis.
• Height-matched staging for automated pipetting workstations interfacing with balance modules and barcode readers.
• GMP-compliant sample staging in QC labs where stainless steel surfaces are mandated for residue-free cleaning validation (e.g., residual solvent testing per ICH Q5C).
• Mounting base for portable XRF analyzers in field-deployable metal alloy verification kits requiring ruggedized, non-magnetic support.

FAQ

Is this platform compatible with vibration-sensitive instruments such as atomic force microscopes (AFM)?
No. While mechanically rigid, it lacks active or passive vibration isolation; users requiring sub-micron stability should integrate it with external optical tables or pneumatic isolators.
Can the height be motorized or integrated with LabVIEW?
Not natively. The unit contains no actuators or feedback sensors. Motorization requires third-party linear actuator retrofitting—not supported by Truelab warranty or qualification documentation.
Does Truelab provide IQ/OQ documentation for this platform?
Yes. Upon request, Truelab supplies a template-based Equipment Qualification Package—including User Requirement Specification (URS), Functional Specification (FS), and test protocols for mechanical verification—aligned with ISO/IEC 17025 and EU GMP Annex 15.
What is the maximum allowable off-center load?
For loads exceeding 25 kg, mass must be centered within a 75 mm diameter circle centered on the platform; eccentric loading beyond this radius may compromise column torsional stability and lock integrity.
Is replacement gear assembly available as a spare part?
Yes. Truelab stocks SS-150×150 Gear Kit (P/N: TK-GK-SS150), including hardened 304 stainless pinion, rack insert, and anti-backlash bushings—shipped with torque calibration certificate.
