Essential Laboratory PP Sink – Small / Medium / Large – Chemical Resistant
Product Overview
The laboratory PP sink—also referred to as the lab sink, polypropylene sink, cup sink, fume hood sink, or wall-mounted sink—is an essential component for every laboratory workspace. Designed for installation in fume hoods, laboratory benches, and wall-mounted applications, these sinks provide a durable, chemical-resistant solution for washing glassware, disposing of reagents, and maintaining a clean work environment.
EduSupports offers a complete range of laboratory PP sinks manufactured from high-density polypropylene (PP) , a material renowned for its exceptional resistance to strong acids, alkalis, and organic solvents—even aqua regia. Unlike traditional metal sinks that rust and corrode, our PP sinks maintain their performance and appearance even after long-term exposure to harsh chemicals.
Available in small, medium, and large sizes, with options for standard, anti-odor, anti-overflow, and wall-mounted configurations, EduSupports has the right sink for your laboratory application.

Why Choose Laboratory PP Sinks?
The laboratory PP sink offers several advantages over traditional metal sinks.
First, its superior chemical resistance makes it ideal for demanding lab environments. PP material withstands exposure to strong acids (including aqua regia), alkalis, and organic solvents that would quickly destroy metal sinks.
Second, the one-piece seamless molding prevents leaks and eliminates rough gaps or dead corners where bacteria and residue could accumulate. This design also simplifies cleaning and maintenance.
Third, the optimized drainage design features a scientifically structured bottom drain hole that solves common problems like slow drainage and standing water. The included filter effectively intercepts experiment residues, glass scraps, and tiny impurities, preventing drain pipe blockage.
Fourth, the thickened, polished sink edge with anti-spill treatment effectively stops chemical liquids and wastewater from splashing or overflowing during vessel cleaning and reagent flushing.
Fifth, the humanized compact design is compatible with almost all fume hood models, requiring no tools for quick installation.

Product Advantages
Optimized Drainage Design
The bottom drain hole adopts a scientific structural design that effectively solves common problems such as slow drainage and standing water. Equipped with a matched filter, it intercepts experiment residues, glass scraps, and tiny impurities, preventing debris from blocking the drainage pipeline.
Thickened Anti-Spill Edge
The sink edge is professionally polished and thickened with anti-spill treatment. This optimized edge design effectively stops chemical liquids and wastewater from splashing or overflowing during vessel cleaning and reagent flushing.
One-Piece Smooth Molding
The entire sink adopts integrated smooth molding technology with no rough gaps or dead corners on the surface. The high-quality PP material features excellent anti-staining performance. Even after long-term contact with various acid and alkali chemical reagents, it will not produce stubborn stains, corrosion marks, or residual dirt.
Easy Cleaning
Daily cleaning only requires simple water flushing. All humanized practical designs greatly improve the efficiency of daily laboratory cleaning and experimental operation while effectively avoiding pipeline blockage, surface corrosion, and liquid leakage damage.
