Stainless Steel Sink Cover LG12

Overview

The Stainless Steel Sink Cover LG12 is an engineered accessory designed for laboratory, pharmaceutical, and cleanroom environments where hygiene, durability, and surface integrity are critical. Constructed from high-grade 304 stainless steel, the LG12 provides a seamless, non-porous barrier over standard undermount or top-mount laboratory sink basins. Its primary functional purpose is to prevent accidental contamination of sink surfaces during non-use periods, suppress aerosol dispersion during high-risk procedures (e.g., chemical rinsing or biohazard waste handling), and serve as a stable, corrosion-resistant work platform adjacent to wet areas. Unlike generic plastic or coated covers, the LG12 leverages the inherent passivation properties of austenitic stainless steel—ensuring long-term resistance to oxidation, chlorides, and repeated exposure to disinfectants such as sodium hypochlorite, ethanol, and hydrogen peroxide solutions. It is not a measurement or analytical device; rather, it functions as a passive, compliance-supporting infrastructure component aligned with ISO 14644-1 cleanroom practices and WHO TRS 961 Annex 2 requirements for containment and surface control.

Key Features

• Material: Cold-rolled 304 stainless steel (0.8 mm thickness), electropolished finish for enhanced corrosion resistance and reduced microbial adhesion
• Design: Precision-laser-cut perimeter with micro-beveled edges to minimize snagging and facilitate wipe-down protocols
• Fitting: Universal contour profile compatible with standard 450 × 450 mm and 500 × 500 mm rectangular sink openings; includes optional silicone gasket kit (sold separately) for positive sealing against splashes
• Surface Integrity: Fully weld-free construction; all corners formed via CNC bending to preserve grain structure and avoid crevice corrosion points
• Cleaning & Sterilization: Autoclavable up to 134 °C (273 °F) for 3 minutes; validated for repeated cycles without dimensional drift or surface pitting

Sample Compatibility & Compliance

The LG12 is not used for sample analysis or processing but supports compliant workflows by maintaining sink area sterility and reducing cross-contamination risk. It complies with EN 10088-2 for stainless steel composition and meets the mechanical performance benchmarks outlined in ASTM A240/A240M for corrosion resistance in mild chemical environments. When deployed in GMP-regulated facilities, its use aligns with EU GMP Annex 1 (2022) Section 4.32 on “prevention of contamination through physical barriers” and supports audit readiness for FDA 21 CFR Part 211.67 (equipment cleaning and maintenance). Documentation includes material certification (EN 10204 3.1) and RoHS/REACH declarations.

Software & Data Management

This is a passive hardware component with no embedded electronics, firmware, or software interface. No data acquisition, connectivity, or digital management functionality is integrated. Maintenance logs—including installation date, cleaning frequency, and visual inspection records—should be retained manually or within facility CMMS platforms per ISO 9001:2015 Clause 7.5.3. Calibration is not applicable; however, periodic verification of surface flatness (±0.15 mm across 500 mm span) using certified straightedges is recommended per internal SOPs.

Applications

• Temporary coverage of sink basins during aseptic filling line setup or equipment qualification activities
• Secondary containment surface for placing calibrated glassware or pipette tips near wash stations without direct contact with drain grates
• Decontamination staging zone adjacent to biosafety cabinets in BSL-2 laboratories
• Work surface extension in compact QC labs where bench space is constrained but sink proximity is required for rapid reagent disposal
• Support element in environmental monitoring programs where sink areas must remain visually and microbiologically controlled between sampling events

FAQ

Is the LG12 suitable for use with acidic or alkaline cleaning agents?
Yes—it withstands prolonged exposure to pH 2–12 solutions at ambient temperature, including nitric acid passivation baths and caustic soda rinses, provided exposure duration does not exceed manufacturer-recommended limits.
Does the cover include mounting hardware or fasteners?
No—LG12 relies on gravity-based placement and optional gasket compression; no drilling, adhesives, or permanent fixtures are required or supplied.
Can it be customized for non-standard sink dimensions?
Yes—custom fabrication is available upon request with minimum order quantities; lead time and dimensional tolerances follow EN ISO 2768-mK standards.
Is third-party validation support provided for GMP audits?
Documentation packages—including material traceability, dimensional inspection reports, and cleaning validation templates—are available to qualified customers under NDA.
