Grade 1 Chromatography Paper 6 x 0.75 Inches for Laboratories, School, Pigment Separation and Experiments [Bag of 50 Strips]

These worked great for ink chromatography. I found that half a strip was plenty to get the colors to separate for my purposes so these will go twice as far.

Great for science experiment

Needed these for school science project. Worked for the experiment as needed. Only complaint is it took forever to get them. Shipping was really delayed.

My son used these for a school project on actual colors in different black ink sources. He did great and the paper did great.

i would say hard to find this for a simple school science project.good thing amazon has it.it does work.

This was the best price for these test strips for color separation for a school science project. Good quality because we got good results.

I bought this to teach a student who is home schooled. Chemistry, specifically for liquid chromatography.....

This did exactly what I needed it for
