pH2100 Flat Tip Plastic pH Electrode

Product Description
Agar plates, skin, and electrophoresis gels are all surfaces that may be difficult to measure with a typical pH glass bulb due to concerns about breakage. To facilitate these and other surface measurements, we created the pH2100 flat tip pH electrode. It has a rugged flat measurement surface, which breaks less easily when it comes in contact with hard materials. This makes it a great choice for measuring slurries, sludges, and viscous samples as well as those containing suspended solids.
  • Ideal for surface measurements and slurries: rugged flat measurement tip resists breakage
  • Great for testing unknown sample types: double junction electrode reference design prevents contamination
  • Durable and Versatile: Ultem® body offers enhanced chemical compatibility and booted BNC protects meter connection
  • No maintenance required: sealed gel filled reference design
  • One year limited warranty: We stand by our products with the Sensorex guarantee
