This product is a spare stopcock for Tarsons Aspirator bottle. This product is durable as Polypropylene bottles provide very good chemical compatibility with a wide variety of lab reagents including most acids, bases, alcohols, aldehydes, esters, and aliphatic hydrocarbons. These aspirator bottles can withstand high autoclave temperatures and can be sterilized. • Quantity provided: 1 stopcock (Aspirator bottle not included) • Material (of aspirator bottle): Polypropylene (PP) • Control and measure the precise amount of liquid required for addition. While they are compatible with a wide range of lab reagents, they can also maintain their flexibility down to temperatures of -40°C. This combined with a cost less than many other materials makes them an overall good choice for many applications. Polypropylene bottles are made only from high quality laboratory grade resin materials that comply with a number of regulatory specifications including USP Class VI, EP monographs, and EU food-contact directives. These aspirator bottles can be used in laboratory procedures to sediment solid or suspended particles in liquid materials. The liquid is filled in the container. After some time, the heavier solid particles deposit at the bottom of the aspirator bottle and the stopcock is opened to release the liquid into a collection flask.
