| Lifespan in Chem Labs | Moderate (Needs frequent replacement) | High (Long-term durability) |
| Maintenance Cost | High (Surface polishing/Treatment) | Low (Simple cleaning) |
| Safety Risks | Possible rust-leakage | Zero-leak integrated molding |
| ROI Period | Short-term utility | Long-term infrastructure asset |
Yes, our sinks are manufactured from 100% high-grade polypropylene, which is specifically engineered to resist highly corrosive substances, including Aqua Regia, acids, and alkalis.
Sinks should be thoroughly cleaned before first use to remove impurities. After experiments, promptly clean the surface to remove chemical residues to prevent potential contamination or long-term degradation.
No. For safety reasons, experimental liquids and solids should be handled in dedicated containers. It is strictly prohibited to pour flammable or explosive substances into the sink to prevent fire hazards.
The overflow pipe and water tank are integrally molded into the sink body, ensuring that if the main drain is blocked, water is diverted safely rather than spilling over onto the lab bench.
Each sink typically includes a professional drainer, a bottle trap, and a downcomer to ensure a complete and leak-proof installation process.
Absolutely. Due to their durability, chemical resistance, and ease of maintenance, they are ideal for the high-turnover and varied chemical use found in university and school science labs.
