Sample bottle cap liners are a common laboratory item used to seal containers holding various liquid or solid reagents. Below is a detailed introduction to sample bottle cap liners.

Material:

Sample bottle cap liners are typically made from materials such as polypropylene (PP) or polytetrafluoroethylene (PTFE). These materials exhibit excellent corrosion resistance and high-temperature resistance, making them suitable for the storage of various chemical reagents.

Types:

Common types of sample bottle cap liners include regular, airtight, and safety liners. Regular liners are suitable for general laboratory operations, airtight liners are used for experiments requiring prevention of gas leaks, and safety liners help avoid injuries from accidental spills of reagents.

Size:

The size of sample bottle cap liners usually corresponds to the diameter of the bottle opening to ensure that the cap can cover the mouth of the bottle and fit tightly, achieving a proper seal. Additionally, there may be slight variations in the sizes of liners produced by different manufacturers, so it is essential to select liners that match the specifications of the bottle.

Usage:

When using sample bottle cap liners, start by cleaning the bottle opening and the cap, ensuring that their surfaces are free from dust or foreign particles. Gently press the cap onto the bottle opening, gradually pressing along the periphery with your fingers until the cap covers the mouth of the bottle and fits snugly. If conducting high-temperature or high-pressure experiments, choose sample bottle cap liners that are heat-resistant and pressure-resistant, and select the appropriate material and model based on the experimental requirements.

In summary, sample bottle cap liners are a common laboratory item with excellent corrosion resistance and high-temperature performance, effectively preventing reagent leaks and contamination, ensuring the accuracy and safety of experiments. When using them, it is important to choose the right material and model, and follow correct procedures for optimal results.
