Nasco Sampling is excited to offer 3 new sizes of Thio-Bags®.

Don’t cut corners with your sample collection supplies. With Whirl-Pak®’s innovative puncture-proof tabs designed with wide flat wire, +1 post-manufacturing sterilization, and our dedication to quality, you can trust our bags from collection through processing.


When out in the field or back in the lab, our self-standing bags keep your hands free without the bulk and expense of having to use a bottle, and we pre-insert a Sodium Thiosulfate tablet into each bag to ensure you always have a safe, secure, and ready-to-use bag for consistency.


Safer, easier to transport, and a real space-saver, Whirl-Pak® stand-up bags offer a perfect alternative to outdated bottles. Additionally, we box our bags in bundles of 25 so you always have a ready-to-use solution.
