Chemical resistant sink
The materials for laboratory sinks mainly include the following types:
Lab epoxy resin sink
Epoxy resin is a type of polymer with many excellent properties. Epoxy resin sinks typically have the following characteristics:
strong corrosion resistance
It can resist the erosion of a variety of chemical reagents, including strong acids, strong bases, organic solvents, etc. This characteristic is particularly important in chemical laboratories, as it ensures that the basin will not be damaged by chemical substances over a long period of use.
smooth surface
The surface of epoxy resin basins is very smooth and not prone to retaining stains and impurities. This makes cleaning easier and can effectively reduce the risk of cross-contamination. At the same time, the smooth surface also helps to observe any subtle changes that may occur during the experimental process.
high strength
Epoxy resin has relatively high strength and hardness, and can withstand certain pressures and impacts. This makes the basin not prone to cracking or damage during use, extending its service life.
shortcomings
Their cost is relatively high, and the price may be more expensive than sinks made of other materials. In addition, under high-temperature environments, epoxy resin may soften or deform, so it is not very suitable for high-temperature experiments.
stainless steel sink
Sinks made of PP material have good chemical corrosion resistance and can resist the erosion of most acids, alkalis, organic solvents, etc. They are lightweight, making them easy to move and install. At the same time, PP material has a certain toughness and is not prone to cracking, making it relatively safe to use in laboratories.
This is a relatively common material in laboratories. Stainless steel sinks are durable, corrosion-resistant, and easy to clean. They can withstand the erosion of various chemical reagents, are not prone to rust, and can maintain good stability even when in long-term contact with acidic or alkaline solutions. In addition, the surface of stainless steel sinks is smooth, making it difficult for stains to remain, which facilitates cleaning and disinfection by laboratory personnel.
ceramic sink
Ceramic sinks are aesthetically pleasing, with smooth surfaces that are easy to clean. They have high hardness and wear resistance, and can withstand a certain amount of impact and pressure. In some laboratories with higher aesthetic requirements, or in environments where high-temperature operations are needed, ceramic sinks are a good choice. However, ceramic sinks are relatively heavy and can easily break when subjected to severe impact.
