Series LG Laboratory Faucets with Water Quality Indicator Light (Duraline Control Valve)

Manufactured from premium materials including PVC, Natural Polypropylene, and High-Purity PVDF, our Series LG Lab Faucets are engineered for use with Distilled, Deionized, Reverse Osmosis, and Ultra-Filtered Water (Type I, II, III). These faucets are designed to meet the rigorous demands of laboratory environments, ensuring optimal water purity and safety.

Key Features:

• Water Quality Indicator Light: Features an integrated resistivity sensor with selectable quality thresholds (options from 10kΩ·cm to 1MΩ·cm). Dual-color LED display provides clear status indication—green light confirms purity above the selected threshold, red light indicates measurements below threshold.
• Safe Operation: Powered through a wall transformer converting 120 VAC to 9VDC, enhancing operational safety and extending product lifespan.
• High Flow Rate: Delivers a maximum flow of 2.5 GPM at 80 PSI when fully opened, tailored for efficient water delivery in demanding applications.
• Versatile Design: Comes with a removable serrated barb tip, leaving a 1/4" Female NPT Outlet for easy attachment of various accessories.
• Innovative "Duraline" Control Valve: Offers effortless operation from full flow to closed with a 120-degree turn, designed with a zero dead leg to prevent microbial growth.
• Durable and Compliant: Manufactured without the use of elastomers, metals, or lubricants and exceeds FDA, USDA, and USP standards. The unique construction is ideal for high-traffic and intensive use settings.
• User-Friendly: Features a black handle with white marker and "DI" text, adhering to SEFA code recommended practices for DI Water Applications. The positive stop at the off position enhances user experience by preventing over-tightening.

Specifications:

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

Sustainability and Maintenance:

• Renewable Design: The Duraline control valve can be fully renewed by replacing the internal cartridge, ensuring a long service life and reducing environmental impact. Repair Kits can be purchased using the following link: REPAIR KITS
• Ultra Smooth Internal Flow Path: Minimizes turbulence and potential for contamination, ensuring the highest quality water delivery.

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.
