Hanna HI4000-47 ISE Slope Check Buffers

Hanna HI4000-47 ISE Slope Check Buffers

The Hanna HI4000-47 ISE Slope Check Buffers ISE Slope Check Buffers are essential solutions used to verify the performance of ammonia or carbon dioxide ion-selective electrodes (ISEs) prior to their initial use or after extended storage. These buffers allow the internal glass pH sensing assembly to be tested and conditioned to ensure proper response before measurements begin.

Features

• Slope Verification for ISEs: Designed specifically for ammonia and carbon dioxide ISEs, the buffer allows users to confirm that the inner pH glass electrode is functioning correctly.

• Simple Conditioning Process: The pH buffer powder packets can be easily dissolved in 50 mL of deionized or distilled water, creating ready-to-use test solutions.

• Electrode Reactivation Support: Ideal for reactivating ISEs after storage, ensuring the pH glass element within the electrode assembly performs optimally.

• Reliable mV Readings: Stabilized readings in the buffer solutions indicate the electrode is functioning correctly; users can calculate the slope by comparing mV values across the buffers.

• Essential Maintenance Tool: Helps prevent inaccurate measurements by identifying electrode performance issues early.
