Hot-Cold Mixer Laboratory Faucet | Model JH-WL012

Key Features

• Single outlet, two-knob control — Separate hot and cold knobs let you adjust temperature and flow at one outlet, so a single tap covers both warm and cold water tasks.
• Solid brass body — A rigid, corrosion-resistant core that withstands daily handling and long-term service in a wet bench environment.
• Matte epoxy powder-coated exterior — A high-grade coating that helps the outer body resist routine acid/alkali splash, UV fading, and heat in general lab conditions.
• 90° turn ceramic headwork — Tested to 500,000 cycles and rated to 10 bar maximum static pressure for smooth, leak-proof control.
• 360° swivel gooseneck spout — Rotates fully to direct flow across the whole basin, making it easy to rinse glassware and fill containers.
• Detachable brass serrated nozzle — Connects to hoses or tubing and takes an attachable splash-control filter; lifts out for easy cleaning.
• Ergonomic high-grade PP knob — Shaped for a comfortable grip and steady one-handed control, including when wet or gloved.
• Bench/deck-mounted — Fits most standard lab sinks and benches.

Technical Specifications

Inlet connection sizes, spout height and reach, and mounting hole dimensions can be confirmed for your project. Share your sink and bench layout, and we’ll advise on the exact fit before you order.

Cold-Only vs Hot-Cold Mixer — Which Should You Choose?

The right faucet comes down to whether your sink point needs warm water as well as cold:

• Hot-cold mixer (JH-WL012): Blends hot and cold water at a single outlet using two knobs. Best where a sink needs temperature-adjustable water — for washing, rinsing, and cleaning tasks that go faster with warm water. Requires both a hot and a cold supply line at the bench.
• Cold-only single outlet (JH-WL001): One dedicated cold-water point in a compact body. Best for standard rinse sinks and workstations that only need cold water, with a simpler build and fewer connections.

Choose the JH-WL012 when a station needs both hot and cold water at one basin. If cold water alone covers the work, the JH-WL001 is the simpler, more economical fit. Tell us what each sink needs, and we’ll match the right tap to your layout.

Applications

The JH-WL012 suits labs that need both hot and cold water at a single sink point:

• General washing — Hand washing, glassware rinsing, and routine cleanup with the temperature set to suit the task.
• Sink-side rinsing — The swivel spout and adjustable flow make everyday rinsing quick and thorough.
• Warm-water cleaning — Clearing residue and stubborn deposits that warm water handles more easily than cold.
• Teaching, research, and testing labs — A dependable, temperature-adjustable washing point for general lab wash-up areas.

Its primary role is temperature-adjustable washing, rinsing, and cleaning at the bench sink, keeping the surrounding worktop tidy during daily use.

Installation & Compatibility

The JH-WL012 is designed for bench/deck mounting at a standard lab sink. Because it’s a mixer, it needs both hot and cold supplies. For a clean, secure fit:

• Confirm that the mounting hole in your bench or sink matches the faucet base, and that there is enough clearance for both knobs and the spout to operate freely.
• Check both inlet connections — the tap needs a hot and a cold supply line, so confirm the connection sizes match your bench plumbing without adapters.
• Confirm your water pressure sits within the headwork’s range (max static pressure 10 bar) for stable, leak-free operation.
• Position the spout so its swivel range covers the basin and flow drains cleanly into the sink.
• Allow clearance above and around the gooseneck for glassware and containers.

Share your sink type, supply connections, and bench layout, and we’ll confirm the right mounting and connection details for your setup.

FAQ

When should I choose a hot-cold mixer instead of a cold-only faucet?

Choose the JH-WL012 when a sink needs both hot and cold water — for washing, rinsing, or clearing residue that warm water handles better. If only cold water is needed, a cold-only faucet like the JH-WL001 is simpler and more economical. The mixer does need both a hot and a cold supply line at the bench.

How do the two knobs work?

Each knob controls one supply — one hot, one cold. Open both and adjust each side to set the temperature you want, then fine-tune together for the flow rate. Both feed the single gooseneck outlet.

Is the JH-WL012 bench- or deck-mounted?

It’s bench/deck-mounted and fits most standard lab sinks and benches. Confirm your mounting hole size and inlet connections with our team and we’ll check compatibility before you order.

What does the epoxy coating protect against?

The matte epoxy coating protects the faucet’s exterior body, helping it resist routine acid and alkali splash, UV fading, and heat in general lab conditions. It’s an external protective finish — for specific or aggressive chemical exposure, send us the details, and we’ll confirm suitability.

What is the max pressure rating?

The 90° turn ceramic headwork is tested to 500,000 cycles and rated to a maximum static pressure of 10 bar for this model. Keeping supply pressure within that range gives smooth, leak-free control and a long working life. If you’re unsure of your line pressure, tell us, and we’ll advise.

Does the nozzle connect to tubing?

Yes. The detachable brass serrated nozzle connects to hoses or tubing, and takes an attachable splash-control filter to reduce splatter. It lifts out for cleaning — remove it, rinse it, and refit it — which keeps the water path clear.

What should I confirm before ordering?

Confirm three things: your sink mounting hole size, your hot and cold inlet connection sizes, and your water pressure. Checking these in advance helps ensure a secure, leak-free fit. Share your setup, and we’ll confirm compatibility.

How do I request a quote?

Send us your required quantities, mounting type, and hot/cold inlet connection details. For a larger fit-out, share your bench and sink layout so we can confirm scope and lead time.
