Hanna HI4005-40 Carbon Dioxide ISE Filling Solution

Hanna HI4005-40 Carbon Dioxide ISE Filling Solution – 4 x 30 mL Bottles

The Hanna HI4005-40 Carbon Dioxide ISE Filling Solution is a high-purity electrolyte filling solution designed specifically for use with the HI4105 carbon dioxide ion-selective electrode (ISE). This solution ensures optimal electrode performance by maintaining the thin film of electrolyte that interacts with the internal pH sensor. The pH change in this layer, caused by the diffusion of carbon dioxide through the gas-permeable membrane, is the key mechanism for accurate CO₂ detection.

Features

• Designed for Carbon Dioxide ISEs: Specifically formulated for the HI4105 CO₂ gas-sensing electrode to ensure stable and accurate operation.

• Critical for Sensor Function: The electrolyte solution creates a reactive surface layer where pH changes occur in response to CO₂ concentration.

• Easy to Use: Supplied in a convenient set of four 30 mL bottles, ideal for routine maintenance and quick refills.

• Optimizes Measurement Accuracy: Proper filling prior to final electrode assembly ensures consistent diffusion response and long-term stability.

• Laboratory-Grade Quality: Manufactured in Hanna’s advanced solution facility under strict quality control for reliable analytical use.
