RG® Red and Blue Litmus Test Paper — 100 Leaves Each

PRODUCT INFORMATION

About this product

This set contains red and blue litmus test papers, with 100 leaves of each colour supplied in protective cases. The papers provide a quick qualitative indication of whether a suitable aqueous sample is acidic or alkaline.

Buyers may search for these as acid-base test paper, red and blue pH paper, chemistry litmus strips or laboratory indicator paper. Separate red and blue papers help demonstrate opposite indicator responses during school, college and routine laboratory work.

Use a clean applicator or suitable sampling method to avoid contaminating the remaining papers. Interpret the colour change according to the procedure, store the cases closed and dry, and use a calibrated pH method when a numerical result is required.
