Polypropylene (PP) test tubes with conical bottoms are laboratory tubes made from polypropylene plastic material, known for its chemical resistance and durability. These test tubes have a conical shape at the bottom, providing a pointed tip. The conical bottom design is particularly useful for applications such as centrifugation or when substances need to be easily poured out without the need for a separate spout.

Here are some key features and characteristics of PP test tubes with conical bottoms:

Material: Polypropylene is a plastic material known for its chemical resistance, making it suitable for a wide range of laboratory applications. PP test tubes are often transparent, allowing for easy visual inspection of the contents.

Conical Bottom: The conical shape at the bottom allows for easy removal of liquids without the need for a separate pouring spout. It is also useful for applications where substances need to be concentrated at the bottom, such as in centrifugation.

Volume Capacity: PP test tubes with conical bottoms come in various sizes to accommodate different volumes of liquids or samples. The volume capacity is typically marked on the side of the tube.

Versatility: These test tubes are versatile and can be used for various laboratory tasks, including sample storage, mixing, and centrifugation.

Chemical Resistance: Polypropylene is resistant to many chemicals, making these test tubes suitable for a wide range of substances. However, it’s essential to check the compatibility with specific chemicals used in experiments.

Autoclavable: Many PP test tubes are designed to be autoclavable, allowing for sterilization through autoclaving to maintain aseptic conditions.

Closure Options: Some PP test tubes may come with caps or closures to secure the contents and prevent contamination.

Disposable or Reusable: Depending on the design, PP test tubes may be disposable or reusable. Disposable tubes are often used for one-time applications to avoid cross-contamination, while reusable tubes can be autoclaved and used multiple times.

These test tubes are commonly used in molecular biology, biochemistry, and general laboratory work. They offer a cost-effective and convenient solution for various applications where the benefits of polypropylene, such as chemical resistance and durability, are desired.
