pH Electrode with Micro Bulb and BNC Connector - HI1083B

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 of less than 100 µL. In the field of biotechnology, samples may need to be measured in test tubes, vials, and NMR tubes, which the small bulb of the HI1083B easily allows for.

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 found in food products 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 types 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.
