Test strips supplied in a classic flat storage box with an integrated color scale for quick and reliable visual comparison of results. Designed for convenient laboratory use, the compact box keeps strips protected and organized while allowing easy dispensing during routine testing procedures. Each strip provides consistent response for dependable measurements in laboratory, educational, and research environments. The clear printed color chart on the box helps users quickly interpret results without additional reference materials. These strips are suitable for general analytical applications where fast qualitative or semi quantitative testing is required. For best performance and stability, store the strips at a controlled temperature between 4–30 °C and keep the container closed when not in use to protect from moisture and environmental exposure.
