A Guide to Puritan's Specimen Collection Systems for Diagnostics


We are no longer just a source for cotton tips and tongue blades. Puritan has evolved into a fully-integrated medical device manufacturer of patented flocked swabs, and a developer of complete specimen collection systems for diagnostics, environmental sampling, and research. All manufacturing—including formulation and fill operations— is still done 100% in the United States, in Guilford, Maine.

We've created this guide to our sampling kit swabs to help you find exactly what you need. Don't see it in this post? One of our knowledgeable product specialists can help you, or we'd be happy to talk about customization options!
