Buffer Solution pH 9 (Borate) – 500ml

Buffer Solution pH 9 (Borate) is a ready‑prepared alkaline buffer solution supplied in a convenient 500ml bottle, specifically designed for use in educational science laboratories. Carefully formulated using a borate buffering system, this solution maintains a stable pH of approximately 9, ensuring reliable and repeatable results during practical investigations.

This product does not have an assigned CAS or UN number (CAS: n/a, UN: NR) as it is a prepared buffer solution rather than a single chemical compound. The borate buffer resists changes in pH when small amounts of acid or alkali are added, making it ideal for experiments requiring consistent alkaline conditions.

Supplied ready to use and clearly labelled, this buffer solution saves preparation time for technicians and supports safe, efficient laboratory practice in schools and colleges.
