A lab plastic gas bulb is a device commonly used in laboratory experiments to control the flow of gases. It is typically made of plastic material that is resistant to chemical corrosion and degradation. The gas bulb consists of a spherical container with a valve that can be opened or closed to regulate the flow of gas.

By squeezing or releasing the bulb, the volume of gas inside can be increased or decreased, allowing for precise control of the gas flow. Lab plastic gas bulbs are commonly used in a variety of laboratory experiments and are known for their ease of use, durability, and versatility.

They are a cost-effective solution for controlling the flow of gases in laboratory settings and are widely used in a range of scientific research and educational applications.
