Hanna HI1093B Extended Length pH Electrode

Hanna HI1093B Extended Length pH Electrode

The Hanna HI1093B Extended Length pH Electrode and HI1093P are specialized combination pH electrodes that feature an extended-length glass body and a 3 mm microbulb tip. As a result, they are ideal for deep, narrow sample containers such as NMR tubes. Designed for accuracy in low-volume samples, this electrode combines a single junction reference, open junction design, and non-aqueous Viscolene electrolyte for exceptional stability—even in challenging sample types.

Key Features

• Extended-Length Body for Deep Access: Unlike standard pH electrodes, the HI1093 series offers an elongated glass shaft. Therefore, it is perfectly suited for applications requiring insertion into narrow tubes or long-necked flasks—such as NMR sample tubes.

• Microbulb Tip (3 mm): Thanks to its ultra-small sensing area, the microbulb tip ensures precise measurements in very small volumes, which are commonly encountered in biotechnology and research labs.

• Open Junction Design: Additionally, the open junction enhances measurement reliability by reducing clogging. This feature is especially important in protein-rich, viscous, or low-conductivity samples.

• Single Junction Reference: While simpler than a double junction, the single reference system performs reliably in controlled environments, particularly when paired with the Viscolene electrolyte.

• Non-Aqueous Viscolene Electrolyte: Unlike typical KCl-based systems, Viscolene supports measurements in non-aqueous or delicate sample matrices where chemical interference must be minimized.

• Low-Temperature (LT) Glass: Because it is designed to function from 0 to 50°C, this electrode performs well in ambient or refrigerated conditions.

• Flexible Connector Options:

  • The HI1093B model includes a standard BNC connector, offering broad compatibility with most meters.

  • The HI1093P version includes BNC + pin, making it fully compatible with Hanna meters that feature CAL Check™ diagnostics.

• Durable Cable: With a 1-meter coaxial cable, this probe is easy to maneuver in both benchtop and field setups.

Technical Specifications

Applications

• NMR Tube pH Testing: Because of its slim, extended body, the HI1093 is an excellent tool for direct measurement inside NMR tubes without the need for sample transfer.

• Microvolume Analysis: In addition, this electrode is ideal for microscale chemical analysis where sample volume is extremely limited.

• Biotech and Pharmaceutical Labs: Its microbulb design and open junction make it highly suited for sensitive biological or organic samples.

• Organic Solvent Systems: Thanks to the Viscolene electrolyte, the probe can be used in non-aqueous environments where traditional electrodes would fail.
