Universal pH Test Strips are a simple and convenient way to check the acidity or alkalinity of liquids. With a wide measuring range from pH 0 to pH 14, these strips are useful for DIY skincare, soap making, cosmetic formulation, laboratory practice, home experiments, water testing, and general liquid testing.

Each strip changes color after contact with the test solution. The result can be compared with the printed color chart included inside the case. The compact plastic storage box keeps the strips clean, dry, and easy to carry.

At Bio Shop™, we recommend Universal pH Test Strips for DIY formulators who want a quick visual pH check while making toners, shampoos, face washes, soaps, creams, and other water-based cosmetic products.

Why pH Testing Matters in DIY Beauty

pH is very important in skincare and cosmetic formulation. A product that is too acidic or too alkaline may feel harsh on the skin, affect product stability, or reduce the performance of certain ingredients.

For example, shampoos, cleansers, toners, and face washes usually need proper pH adjustment before use. Universal pH Test Strips help you quickly check whether your formula is in the expected range before final packing.
