Narrow Mouth Plastic Lab Bottles are a type of laboratory containers that are designed to store testing materials, samples and reagents. These bottles have a narrow neck opening and a wide body for maximum storage capacity. Unlike other containers, their narrow mouth makes them easier to use when measuring out small amounts of liquids or powders. They are also made from a special plastic that is resistant to chemical and physical damage, so they can be used for a wide variety of applications. These bottles are an essential part of any laboratory and are available in a variety of sizes, colors, and shapes to meet most laboratory needs.
