If the vial is too small to bear the entire label contents as required by regulations then you have a number of options..

- The vials can be overpacked in a container of adequate size to accommodate the label.
- The vials can be identified with hang tags affixed in a manner that is sufficiently durable.
- The vials can be identified with an unambiguous code that matches an entry in a log book that remains with the collection. 

The choice depends on convenience and practicality.

Dear DCHAS Listers:

 

I am looking guidelines on "labeling" synthesized products/compounds in small quantities in vials/flasks (RBF).. This is mainly problem in synthetic groups in the chemistry dept. Generally, synthetic chemists generate hundreds of compounds during their Ph. D. program and they like to keep a small portion of the compound for the future use such as TLC and other analytical reference purpose..

   

What is the appropriate practice for labeling these sample vials and small flasks?

 

Actual chemical names/structures/Note book reference such as AB-12-B?

 

When a flask can be labeled during routine lab work?  As an example, I am working on a column purification, and I have multiple concentrated fractions from the column.

Any information will be highly helpful.

 

Regards,

 

Tilak
