100-Pack Grade-1 Chromatography Paper Strips - 6" x 0.75" Pigment Separation Blotting Strips for Science Experiments & Laboratories - Clear Separation Filter Paper Set - White, Rectangular

I bought these on Amazon as I didn’t have time to get them from my normal supplier. They work great! I used them for simple chromatography with markers and water with kids.

Product arrived promptly and in excellent condition. The paper strips were a very nice quality and were just what we needed for our experiments.

Looking for something cheap yet decent for chromatography experiments with my students. These were perfect. No cutting needed, nothing special we had to do but the experiment itself. Would buy again for STEM experiments in my science classes.

Happy with our current mailman, who is the last link in the delivery chain....100% improvement over our earlier mail person!

Used for ink chromotography in a science class. They were much more expensive compared to larger papers that could just be cut to size but I needed them quickly and these shipped Prime.

I use these for testing out my fountain pen ink collection, and they work wonderfully. No problems at all.

Students enjoyed chromatography lab using this product. Price is great

As part of our church's after school STEM program we used these strips to teach middle school students about chromatography. We used these strips as part of an experiment to determine what materials go into making inks, food coloring and dry erase markers. Everyone had fun and learned a lot.
