Ion Selective Electrodes ISE

 We supply a range of  high performance ion selective electrodes that are manufactured in the US.  All ion selective electrodes are factory calibrated and the Bante instrument will automatically recognise the specific probe.The  ion selective electrode measures the  ion directly in solution and there is no need for any pre-treatment with caustic chemicals, and no noxious gases are liberated.

These electrodes have a solid state membrane and a solid internal contact – i.e. they do not contain any liquid or gel electrolytes. Their characteristics and advantages are:

· All solid-state construction.
· Simple gold-plated plug-in connectors.
· Robust and Durable.
· Easy to handle.
· Stable electrochemical potential.
· Fast response time.
· Function in any position.
· No leaking of fluids.
· Long shelf life and working life.
· Can be stored and transported below 0°C.

An  ion selective electrode or ISE (with its own internal reference electrode ) is immersed in an aqueous solution containing the ions to be measured, together with a separate, external reference electrode. (NB: this external reference can be completely separate or incorporated in the body of the ISE to form a Combination Electrode.) The electrochemical circuit is completed by connecting the electrodes to a sensitive milli-volt meter using special low-noise cables and connectors. A potential difference is developed across the ISE membrane when the target ions diffuse through from the high concentration side to the lower concentration side
