The HIRANUMA GR-525BZ Glass-Reference Electrode, 205 mm (HIRAN-D254703-A; manufacturer part D254703-A) is a combination electrode designed for neutralisation titration in Erlenmeyer flasks. It integrates glass indicator and reference-electrode functions in a 205 mm body and includes a 0.6 m connection cable.
Key Features
- Integrated glass-reference configuration, combining the indicator and reference-electrode functions in one probe
- Designed for neutralisation titration, supporting potentiometric analysis of acids and bases
- Erlenmeyer-flask configuration, with an extended body designed to reach into conical laboratory vessels
- 205 mm electrode body, providing the long-body format specified for this model
- 0-80°C operating range, supporting titration across a broad range of sample temperatures
- 4 M potassium chloride internal solution, providing the specified reference-electrode electrolyte
- 0.6 m connection cable, providing practical reach between the electrode holder and titrator
- HIRANUMA titrator compatibility, listed for use with COM-A19 and legacy COM-300A automatic titrators
Note: This long-body electrode is intended for an appropriate electrode holder and Erlenmeyer-flask setup. Confirm the required holder configuration for the intended titrator before ordering.
Benefits
- Reduces the number of separate probes required by combining glass-indicator and reference functions.
- Supports reliable potentiometric endpoint detection for routine acid and base titrations.
- Provides improved access to samples held in deeper Erlenmeyer flasks through its extended body.
- Allows compatible COM-A19 and COM-300A systems to be configured with the specified standard combination electrode.
