Sample Containers

Definition

Sample containers are specialized vessels used to collect, preserve, and transport scientific samples, particularly in the context of space exploration. These containers are designed to maintain the integrity of the samples while protecting them from contamination, external environmental conditions, and degradation during transit back to Earth or to laboratories for analysis. The technology behind these containers must address various challenges, including the vacuum of space, radiation exposure, and temperature fluctuations.

5 Must Know Facts For Your Next Test

1. Sample containers must be made from materials that can withstand extreme temperatures and radiation found in space without degrading or leaching substances into the samples.
2. They often incorporate seals or barriers that prevent contamination from external sources, ensuring that samples remain pristine from collection to analysis.
3. Different types of sample containers are required for various types of samples, such as solids, liquids, gases, or biological materials, each designed with specific features to suit their purpose.
4. Innovations in sample container technology include adaptive designs that can change based on the sample's needs during transport, enhancing preservation methods.
5. NASA and other space agencies conduct rigorous testing of sample containers on Earth to simulate space conditions and ensure they will perform adequately during missions.
