Why is it important that labels in specimen jars be made of special paper that does not disintegrate in alcohol?

• A. The labels record critical information and must survive isopropyl alcohol storage.
• B. Labels are used as decorative notes in the jars.
• C. The paper should dissolve in alcohol to indicate degradation.
• D. Labels can be replaced easily if lost.

Answer: (A)

Labels on specimen jars must stay legible and attached throughout storage in alcohol because they carry essential information about the specimen—what it is, where and when it was collected, who collected it, and other details that identify and provenance-tag the sample. Alcohol-preservative environments can weaken ordinary paper, causing ink to smear, the label to deteriorate, or it to detach from the jar. Using special paper that doesn’t disintegrate in alcohol keeps the data intact and readable over time, which is crucial for accurate identification, future reference, and reliable scientific work. Decorative notes are not the purpose of labels, dissolving the label would defeat their function, and the ability to replace labels easily does not justify allowing data loss.
