Swivel Lab Faucets w/ Water Quality Light (Duraline Control Valve)

The Series LG Swivel Laboratory Faucets with Water Quality Indicator Light are manufactured from premium materials including PVC, Natural Polypropylene, and High-Purity PVDF. Unlike our standard fixed gooseneck faucets, this category includes an integrated swivel union, allowing the gooseneck to be freely rotated 360° without loosening any components. This provides superior flexibility and ease of use in laboratory environments, while maintaining full seal integrity. These faucets are engineered for use with distilled, deionized, reverse osmosis, and ultra-filtered water (Type I, II, III), ensuring optimal water purity and safety.

Key Features

  • Water Quality Indicator Light: Integrated resistivity sensor with selectable quality thresholds (10kΩ·cm to 1MΩ·cm). Dual-color LED display indicates purity status—green light confirms above-threshold purity, red light signals below-threshold.
  • Swivel Union: Provides complete 360° gooseneck rotation while maintaining seal integrity, a key feature unique to this faucet category.
  • Safe Operation: Powered by a wall transformer converting 120 VAC to 9VDC for safe, reliable operation.
  • High Flow Rate: Maximum 2.5 GPM @ 80 PSI for efficient water delivery in demanding lab applications.
  • Versatile Design: Removable serrated barb tip leaves a 1/4" Female NPT outlet for attaching accessories.
  • Duraline Control Valve: Effortless 120° operation from full flow to closed with a crevice-free, zero dead leg geometry to reduce microbial growth.
  • Durable & Compliant: Constructed without elastomers, metals, or lubricants in wetted path. Meets or exceeds FDA, USDA, and USP standards for laboratory use.
  • User-Friendly: Black handle with white marker and "DI" text, per SEFA Code No. 7 for DI Water Applications. Positive stop prevents over-tightening.

Specifications

  • Max Operating Pressure: 150 PSI
  • Cord Length: 9 feet for flexible installation
  • Connection: 3/8" Female NPT inlet with included 3/8" O.D. tube × 3/8" MNPT compression fitting

Sustainability and Maintenance

  • Renewable Design: Duraline control valve cartridge is fully replaceable. Repair kits available.
  • Ultra-Smooth Flow Path: Internal design minimizes turbulence and contamination risk, ensuring consistent high-purity water delivery.
