ROSS™ pH Electrodes

The Best Choice for Superior Stability, Rapid Response, Accurate and Reproducible pH Measurements.

Standard ROSS electrodes provide the same rapid response, accuracy and temperature response of all ROSS electrodes.

The reference system provides excellent stability. These electrodes provide a one year warranty. They are available in a variety of styles such as the clog free Sure-Flow junction, glass or epoxy electrodes, flat surface, semi-micro, micro and spear tip designs.

All standard ROSS electrodes have a refillable design and do not contain a built-in-temperature element.

The Thermo Scientific Orion ROSS electrode line offers a wide variety of quality pH electrodes to choose from. There are many different factors to consider when you selecting a pH electrode to ensure you select the electrode that will suit your needs.

You will need to consider body materials, body styles, and sample requirements. For easy selection, we have broken down the range into several sub-categories, with more information and products on each tab.

ROSS

Standard Glass Electrodes

ROSS Standard Glass Electrodes

ROSS Glass Bodied Electrodes provide precise pH measurements and measurement stability regardless of temperature changes or sample composition. The electrodes are 12mm in diameter, can be used in a wide variety of samples and are easy to clean.

Standard Epoxy Electrodes

ROSS Standard Epoxy Electrodes

ROSS Epoxy Bodied Electrodes provide precise pH measurements and measurement stability regardless of temperature changes or sample composition. The electrodes are 12mm in diameter and the extremely durable, rugged body helps prevent accidental breakage.

Sure-Flow Electrodes

ROSS Sure-Flow Electrodes

ROSS Sure-Flow Electrodes incorporate a free-flowing junction that is easy to clean and never clogs. These electrodes are ideal for dirty or viscous samples that clog traditional electrodes.

Semi-micro Electrodes

ROSS Semi-micro Electrodes

ROSS Semi-micro Electrodes are designed for applications where sample volume is limited and can take measurements in samples of 0.2mL volume. They are available with chemically-resistant glass (6mm tip), epoxy (8mm tip) bodies or Sure-Flow junction.

Micro pH Electrodes

ROSS Micro pH Electrodes

ROSS Micro pH Electrodes have been designed to measure extremely small samples. The measuring tip is 3mm in diameter and  40mm long. The minimum depth of immersion is 4.5mm and the minimum sample size is 15μL in 384 well plates.

Rugged Bulb Electrodes

ROSS Rugged Bulb Electrodes

ROSS Rugged Bulb Electrodes provide precise pH measurements and measurement stability regardless of temperature changes or sample composition. The electrodes are 12mm in diameter and have an extra durable pH bulb to help prevent breakage.

Flat Surface Electrodes

ROSS Flat Surface Electrodes

ROSS Flat Surface Electrodes provide precise pH measurements and measurement stability regardless of temperature changes or sample composition. The electrodes are designed for use in small samples or ideally measuring the surfaces of solid or gel samples.

Spear Tip Electrodes

ROSS Spear Tip Electrodes

ROSS Spear Tip Electrodes provide precise pH measurements and measurement stability regardless of temperature changes or sample composition. The electrodes are designed for use in small samples or ideally piercing solid or semi-solid samples.
