Rubber stoppers play a crucial role in the collection and preservation of blood samples. They are used to seal the vials and tubes that contain the blood, ensuring that the samples remain uncontaminated and stable until they can be analyzed. The integrity of the blood sample is maintained through the use of high-quality rubber stoppers that are specifically designed for this purpose.

Importance of Rubber Stoppers in Blood Sample Integrity

The integrity of a blood sample is compromised if it is exposed to air, or contaminants, or if it is not stored under the correct conditions. Rubber stoppers are essential in preventing these issues, as they create a tight seal that keeps the sample secure. This is particularly important when considering the various tests that blood samples undergo, such as blood typing, disease screening, and genetic testing.

Selection Criteria for Rubber Stoppers in Blood Collection

When selecting rubber stoppers for blood collection, several factors must be considered to ensure that they are suitable for their intended purpose. These factors include:

1. Material: The rubber used in the stoppers should be of medical grade to ensure that it does not contaminate the blood sample. It should also be non-toxic and hypoallergenic.
2. Compatibility: Rubber stoppers must be compatible with the various chemicals and reagents that may come into contact with them during the blood collection and testing process.
3. Seal Quality: The stoppers must provide a secure seal to prevent leakage and contamination of the blood sample.
4. Ease of Use: The rubber stoppers should be easy to apply and remove, without causing damage to the vial or tube.
