The Hitachi HIRANUMA PR-731BZ Platinum Combination Electrode (D254706-A; JMG code HIRAN-D254706-A) combines platinum indicator and reference-electrode functions for redox titration in test tubes or closed cells. It has a -5 to 100°C operating range, uses 4M KCl inner solution and includes a 0.6 m cable.
Key Features
- Combined platinum and reference-electrode design, integrating both measurement functions into one assembly
- Designed for redox titration, supporting oxidation-reduction endpoint detection
- Suitable for multiple redox analytes, including metal ions such as Cu2+ and Fe3+, iodine and hydrogen peroxide
- Suitable for test tubes and closed cells, providing a dedicated configuration for compact vessels
- Minimum vessel diameter of 18 mm, as specified for compatible test tubes and closed cells
- Maximum vessel height of 105 mm, based on the manufacturer’s stated vessel requirements
- Broad operating temperature range, specified from -5 to 100°C
- 4M potassium chloride inner solution, as specified for the PR-731BZ configuration
- Integrated 0.6 m cable, providing connection reach around the titration station
- Slender lower electrode shaft, measuring 100 mm long and 8 mm in diameter
- Defined body dimensions, with a 165 mm body length, 16 mm collar diameter and 25 mm collar height
- Dedicated HIRANUMA titrator accessory, with COM-300A and COM-A19 compatibility listed by John Morris Group
Note: Confirm the instrument connection, vessel dimensions and inner-solution requirements for the intended titration method before ordering.
Benefits
- Reduces the number of separate electrodes required by combining platinum indicator and reference functions.
- Supports redox titration in compact test tubes and closed cells where available vessel space is limited.
- Provides defined vessel and electrode dimensions to simplify configuration planning.
- Supports a broad range of compatible sample temperatures through its -5 to 100°C operating range.
- Helps reduce replacement errors through clear PR-731BZ and D254706-A identification.
