Amendment I - The purpose of amendment I is to respond to an industry inquiry.
Question: The description states crimp vials with 4 different color crimp seals. We do not use crimp seals much anymore and I’m not even sure we can get them in 4 different colors. Are screw cap vials acceptable?
Response: No, screw cap vials are not acceptable.
All other terms and conditions remain unchanged, as a result of this amendment.
