  • Quick pH Testing

    A litmus or pH strip gives a fast colour-based reading of a solution's acidity or alkalinity.

  • Chromatography

    Chromatography paper separates mixed pigments or compounds as solvent travels up the strip.

  • Matched Filter Sizes

    Different filter paper diameters suit different funnel sizes and filtration volumes.

  • Continuous Test Rolls

    A roll of universal indicator paper offers a convenient, cut-to-length supply for routine testing.
