Surfaces like paper, leather, electrophoresis gels and agar plates may be difficult to measure with traditional pH glass bulbs due to concerns about breakage. A flat electrode like our pH2500, is ideally suited for these types of pH measurements as well as measurements of suspended sludges and slurries. In addition to its specially designed measurement surface, the pH2500 features double junction construction, which prevents contamination and allows testing of samples containing heavy metals or proteins.

• Accurate measurements across full pH scale (0-14)
• Highly adaptable: Compatible with any pH meter accepting BNC
• Low maintenance: Gel-filled electrode reference design with double junction to prevent contamination
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
