CZGY RH-150 Stainless Steel Laboratory Height-Adjustable Workstation

Overview

The CZGY RH-150 Stainless Steel Laboratory Height-Adjustable Workstation is an engineered solution for precise vertical positioning of analytical instruments, sample containers, and modular lab modules within controlled laboratory environments. Built on a monolithic 304 stainless steel architecture, it operates via a calibrated manual lead-screw elevation system—eliminating hydraulic or pneumatic components to ensure long-term dimensional stability, zero fluid leakage risk, and full compatibility with cleanroom-grade maintenance protocols. Its design adheres to the mechanical and material requirements specified in ISO 15190:2020 (Laboratory safety — General requirements) and supports alignment-critical workflows such as pipette calibration, spectrophotometer cuvette positioning, and gravimetric balance setup where consistent horizontal plane registration is essential.

Key Features

• Fully welded 304 stainless steel construction with electro-polished surface (Ra ≤0.8 µm), providing resistance to organic solvents, diluted mineral acids (e.g., HCl ≤10%, HNO₃ ≤20%), and alkaline reagents commonly used in wet chemistry labs
• Manually actuated precision lead-screw lift mechanism with dual-locking knurled knobs—enabling repeatable height setting within ±0.3 mm tolerance across the full 70–120 mm travel range
• 150 mm × 150 mm flat, non-perforated work surface with integrated chamfered edges (2 mm radius) to prevent tool slippage and facilitate wipe-down cleaning
• No exposed fasteners or crevices; all welds ground and blended per AWS D18.1 standards to eliminate microbial harborage points
• Load-rated for static distribution up to 25 kg—validated per ASTM E178-22 (Standard Practice for Dealing with Outlying Observations) using calibrated deadweight testing

Sample Compatibility & Compliance

The RH-150 accommodates standard laboratory vessels including 100 mL–1 L volumetric flasks, NMR tubes (up to 10 mm OD), HPLC autosampler trays, and benchtop pH meters. Its inert surface prevents catalytic interference during trace metal analysis and eliminates silicone or polymer leaching concerns associated with coated or composite platforms. The unit complies with material biocompatibility requirements outlined in USP and for non-implantable devices, and its surface passivation meets ASTM A967 Method AB (nitric acid) specifications. It is suitable for use in GLP-regulated environments where equipment qualification (IQ/OQ) documentation must demonstrate mechanical reproducibility and material traceability.

Software & Data Management

As a purely mechanical height-adjustment platform, the RH-150 requires no firmware, drivers, or software integration. Its operational integrity is verified through documented mechanical calibration—performed annually using certified gauge blocks (NIST-traceable, Class B) and digital height gauges (resolution: 0.01 mm). Calibration records include serial-numbered entries, operator ID, environmental conditions (temperature/humidity), and uncertainty budgets per ISO/IEC 17025 Clause 6.5. No electronic data logging is embedded; however, height settings may be recorded manually in lab notebooks or integrated into LIMS workflows via standardized SOP templates (e.g., “RH-150 Position Log – Form LAB-EQP-047”).

Applications

• Height optimization of UV-Vis spectrophotometers for consistent beam-path alignment across cuvette batches
• Ergonomic repositioning of digital balances during multi-step gravimetric titrations to reduce operator fatigue and posture-related error
• Stable support for hotplate-magnetic stirrers during reflux condensation setups requiring thermal isolation from bench surfaces
• Modular integration beneath fume hood sashes to elevate reaction flasks for improved vapor capture efficiency
• Base platform for custom-built automated liquid handling jigs where vibration damping and thermal mass stability are prioritized over motorized motion

FAQ

Is the RH-150 compatible with cleanroom Class 1000 (ISO 6) environments?
Yes—its seamless welds, electro-polished finish, and absence of lubricants or particulate-generating mechanisms meet ISO 14644-1 particle count thresholds when installed with appropriate airflow management.
Can it be sterilized using vaporized hydrogen peroxide (VHP)?
Yes—the 304 stainless steel substrate and passivated surface are validated for ≥100 VHP cycles per ISO 14937 Annex C without loss of corrosion resistance or surface roughness.
Does CZGY provide installation qualification (IQ) documentation?
Yes—standard IQ packages include as-built drawings, material certificates (EN 10204 3.1), passivation test reports, and mechanical calibration records upon request.
What is the recommended maintenance interval?
Visual inspection and functional check every 6 months; lead-screw lubrication with Dow Corning® Molykote® G-Rapid Plus grease only after 12 months or 500 elevation cycles—documented per SOP LAB-MNT-012.
