Laboratory PP sink is one of the most important components in modern laboratory furniture systems. These sinks are designed for chemical resistant sinks, polypropylene— A thermoplastic resistant polymer known for its excellent chemical, corrosion, and physical resistance.
Laboratories often deal with corrosive substances such as strong acids, alkalis, solvents, and chemical agents.
Today, PP laboratory sinks are widely used in:
Chemical laboratories
Pharmaceutical research facilities
Universities and teaching laboratories
Medical diagnostic laboratories
Food testing laboratories
Industrial research and development centers
Because of their strong chemical resistance, lightweight structure, and cost-effectiveness, ZOOANY laboratory PP sinks have become the preferred sink solution for laboratory furniture manufacturers and laboratory planners worldwide.
Polypropylene (PP) is a thermoplastic polymer widely used in chemical equipment, medical devices, and industrial applications.
It is known for its excellent balance of durability, chemical resistance, and lightweight properties.
High chemical resistance
Excellent impact strength
Lightweight structure
Good heat resistance
Moisture resistant
Non-toxic and environmentally friendly
These characteristics make polypropylene an ideal material for laboratory sinks.
Laboratories demand equipment that can withstand harsh conditions while maintaining safety and durability.
Polypropylene can resist most acids, alkalis, salts, and many organic solvents commonly used in laboratories.
Unlike ceramic sinks, PP sinks do not crack easily when glassware accidentally falls into them.
PP sinks are much lighter than stainless steel or ceramic sinks, making them easier to transport and install.
Compared to epoxy resin sinks, PP sinks are significantly more affordable.
With proper maintenance, PP sinks can last 5–15 years or longer.
A laboratory polypropylene sink typically consists of several engineered components.
The basin is the main container where washing and cleaning take place. It is usually deeper than household sinks to accommodate laboratory glassware.
The drain outlet connects the sink to laboratory waste systems. It is usually made of chemical-resistant polypropylene or PVC.
Some sinks include overflow holes to prevent water from spilling onto laboratory floors.
Raised edges help reduce splashing when cleaning equipment.
Laboratory faucets such as gooseneck taps or triple taps are typically installed near the sink.

Laboratory sinks are available in various designs to suit different applications.
The most common type used in laboratory benches.
Best for:
Small laboratories
Standard washing tasks
Allows separation of cleaning tasks.
Example workflow:
One side for washing
One side for rinsing
A small sink designed for draining liquids or rinsing small equipment.
Commonly installed on laboratory workbenches.
Designed for large glassware such as:
Flasks
Cylinders
Beakers
Deep sinks are commonly used in research laboratories.
Laboratory sinks come in various sizes depending on laboratory design.
