Key Benefits
- Good chemical resistance for demanding labs — The cast epoxy body resists many common laboratory reagents, so it holds up to corrosive rinse and disposal tasks without degrading.
- Handles high-temperature wash-up — Epoxy resin tolerates hot water and elevated-temperature tasks that put extra stress on the basin, making it a strong fit for hot work.
- Solid, monolithic construction — Cast as one piece with no seams, the rigid body resists cracking, flexing, and wear through frequent daily use.
- Integral edge for clean undermount fit — The molded edge (lip) supports the basin at the worktop joint and helps create a tidy, flush under-worktop finish.
- Scratch-resistant matt lip — The matt finish resists scratches and blends with most worktop surfaces for a consistent bench appearance.
- Complete PP accessory set — Ships with PP overflow, stopper, and filter/basket strainer as standard, so the unit is ready for installation upon arrival.
What “With Edge” Means
The “edge” refers to the integral molded lip cast into the top of the basin. It is a structural feature, not just a visual one:
- Support at the joint — The edge rests against or beneath the worktop opening, helping carry and locate the basin during undermount installation.
- Cleaner sealing surface — It provides a defined face for sealing the sink-to-worktop joint, which supports a tidy, leak-resistant finish.
- Consistent bench look — The scratch-resistant matt edge sits flush with the worktop for a clean, cohesive appearance.
Why Choose Epoxy Resin
Epoxy resin is one of four common lab sink materials, alongside polypropylene (PP), ceramic, and stainless steel. Each suits different conditions. Use the guidance below to match the material to your workflow.
| Consideration | Epoxy Resin | PP | Ceramic | Stainless Steel (304) |
|---|---|---|---|---|
| Best for | Combined chemical + heat exposure; heavy-duty wash-up | Corrosive chemical handling; light weight | High-heat work; strong-acid environments (except HF) | Durable, hygienic general wash-up |
| Chemical resistance | Good resistance to many reagents | Broad resistance to many reagents | Broad resistance, including many strong acids | Good for general use; limits with chlorides and some acids |
| Heat tolerance | Handles elevated-temperature wash-up | Suited to lower-temperature tasks | Handles high-temperature work | Tolerates routine hot wash-up |
| Construction | Solid cast, monolithic body | Lightweight molded body | Hard glazed body | Welded metal body |
| Weight | Heavy; needs sturdy support | Lightweight | Heavy; needs sturdy support | Moderate |
Choose the JH-ES003 epoxy resin sink when:
- Your work combines corrosive chemicals with elevated temperatures.
- You need a hard, monolithic basin that resists cracking and wear.
- A rigid, seamless cast body matters more than low weight.
Consider an alternative when:
- Weight or budget is the main driver — PP may be more practical.
- You handle hydrofluoric acid or need the highest heat tolerance — ceramic may suit better.
- You need a metal basin for general hygienic wash-up — stainless steel is a strong fit.

Applications
The JH-ES003 is best suited to labs where chemical resistance and heat tolerance both matter:
- Research laboratories — A durable, chemical-resistant basin for facilities handling varied reagents day after day.
- High-temperature wash-up points — practical drain points where hot processes or elevated temperatures are routine.
- Strong-chemical environments — A reliable rinse-and-drain point for demanding chemistry work.
- Teaching and institutional labs — A hard-wearing basin for high-traffic benches that see frequent cleaning and rinsing.
For continuous exposure to highly aggressive reagents, confirm compatibility with our team so we can advise on the right material.
Installation Notes
The JH-ES003 is designed for under-worktop (undermount) installation, mounting beneath the bench surface for a clean, flush finish. Because cast epoxy resin is heavy, the setup depends on proper support.
For a reliable, leak-free result:
- Confirm load support — Make sure the worktop and cabinet structure can support the sink’s weight when fully loaded; a support frame or bracket beneath the worktop is typically required.
- Match the cutout — Cut the worktop opening to the confirmed basin and edge dimensions for a clean undermount fit.
- Seal the joint — Properly seal the joint between the sink edge and worktop to prevent water ingress and protect the worktop core.
- Align the drain — Confirm the drain outlet lines up with your plumbing run before final fixing.
- Level and support before use — Confirm the basin sits level and is fully supported along its edge before commissioning.
Share your bench design, worktop material, and drainage layout, and we’ll help confirm the right support and cutout setup for your lab.

FAQ
Why choose an epoxy resin sink for a lab?
Epoxy resin combines good chemical resistance with high-temperature tolerance in one solid cast body. It’s a strong fit where a lab needs a hard, seamless basin that handles both corrosive reagents and hot-work tasks without degrading.
What chemicals can the JH-ES003 handle?
The cast epoxy body offers good resistance to many common laboratory reagents. Because performance depends on the specific chemical, concentration, temperature, and contact time, confirm suitability for your application. Send us your main reagents, and we’ll advise on compatibility.
Is it suitable for high-temperature work?
Yes. Epoxy resin tolerates hot water and elevated-temperature wash-up better than lighter polymer sinks. Because real-world limits depend on your conditions, share your peak operating temperatures, and we’ll confirm suitability.
What does “with edge” mean?
The edge is the integral molded lip cast into the top of the basin. It helps support and locate the sink at the worktop joint during undermount installation, provides a defined sealing surface, and gives a clean, flush bench finish.
What accessories are included?
Each sink ships with a complete set of PP accessories: overflow, stopper, and filter/PP basket strainer. These come as standard, so the unit is ready to install on arrival.
What colors are available?
The JH-ES003 is available in black, white, and gray, so you can match it to your bench and lab design.
How is the sink installed?
The JH-ES003 is designed for under-worktop (undermount) installation. Because cast epoxy is heavy, the worktop and cabinet must support its weight — usually with a support frame or bracket. Match the cutout to the basin and edge dimensions, seal the joint, and align the drain before final fixing.
