When choosing a laboratory countertop, multiple factors need to be considered, including chemical corrosion resistance, physical strength, conductivity/insulation, ease of cleaning, wear resistance, thermal stability, economy, environmental friendliness, and surface flatness. Different laboratory countertop materials have varying resistance to acids, alkalis, solvents, etc. Therefore, it is crucial to choose the appropriate countertop material based on the specific needs and standards of the laboratory. Here are some common laboratory countertop materials and their characteristics:

Phenolic resin countertop: suitable for chemical and physical laboratories, with characteristics such as high temperature resistance, wear resistance, scratch resistance, and certain fire resistance.

Epoxy resin countertop: suitable for chemical laboratories, with strong acid and alkali corrosion resistance, wear resistance, impact resistance, pollution resistance, and high temperature resistance up to 600 ℃.

Solid core physical and chemical board countertop: suitable for physical and biological laboratories, easy to clean, good load-bearing capacity, acid and alkali resistance, high temperature resistance of 180 ℃, radiation resistance, antibacterial and wear-resistant.

Stainless steel countertop: suitable for chemical and biological laboratories, corrosion-resistant, easy to clean, and suitable for many chemical and biological experiments.

Ceramic countertop: suitable for chemical laboratories, with high temperature resistance, chemical corrosion resistance and other characteristics, but fragile and not resistant to vibration, acid resistance, high temperature resistance of 1200 ℃, can be polished and repaired, high hardness, high density, impact resistance and flame retardancy.

Marble countertop: suitable for physics and biology laboratories, easy to clean, can be polished and repaired, with the same color glue, seamless and irregular shape, especially without fine pores, bacteria cannot invade.

PP countertop: Suitable for physics and biology laboratories, PP material has good acid and alkali resistance and can withstand corrosion from various acid and alkali solutions. This characteristic makes the PP experimental bench perform well in experiments in the fields of chemistry, biology, medicine, etc., and can maintain a stable working state for a long time, effectively extending the service life of the experimental bench.

When choosing a test bench, it should be determined based on the specific needs and budget of the laboratory. For example, for chemical laboratories that require high corrosion resistance and high temperature resistance, epoxy resin and ceramic countertops are better choices; For laboratories that require high strength and no bacterial residue, stainless steel countertops may be more suitable. At the same time, considering the cost and convenience of maintenance, psychological boards and marble countertops also have their application scenarios.
