Description

The HI1083B is a glass body, single reference junction micro pH electrode with a BNC connector. The HI1083B has a unique open junction design in which there is a viscolene (hard gel) electrolyte layer that is free of silver chloride (AgCl) between the sample to be measured and the internal reference cell.
This electrode has a bulb tip that is only 3 mm in diameter and can be used to measure pH in samples as little as 100 µL. The HI1083B is ideal for 96 well plates and for expensive samples that offer little volume to work with.
Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.
The HI1083B uses general purpose (GP) glass, micro bulb, glass body, and open junction with viscolene gel electrolyte.
General Purpose Glass Formulation
General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25^°C and is suited for measuring pH of samples that are at ambient temperatures. The HI1083B is suitable to use with samples that measure from 0 to 50^°C.
Micro Bulb Tip
The 3 mm micro bulb tip design allows for measurement in samples less than 100 µL. The small diameter of the probe allows for the measurement of pH in 96 well plates, test tubes, and vials.
Glass Body
The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the electrode reaches equilibrium, the steadier the reference potential.
Open Junction Reference
Suspended solids and proteins will clog a conventional ceramic reference junction. This clogging will impede the measurement circuit between the indicating electrode and the internal reference resulting in slower response time, erratic readings, and frequent electrode replacement. The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable readings.
BNC Connector
The HI1083B uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input. Other type of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
