pH and ORP Electrodes and Solutions

Your simple aqueous pH measurements are used to qualify a sample's acidity as part of general laboratory use and requirements. 

Use these pH electrodes for general purpose, simple pH samples. 

The atmosphere you work in calls for rugged design that ensures accuracy in harsh environments, as precision in real-time sample testing crucial. pH electrodes recommended for field use and plant samples should have an epoxy body for added durability and be polymer or gel filled for easy maintenance.

Use pH electrodes for field use and plant samples for water (lakes, ponds, streams, rivers, etc.), wastewater, food manufacturing, cosmetics, pulp and paper, petrochemicals, and more.

Sample preparation is a critical part of your testing workflow—accurate and reproducible measurements are imperative. For the early stages of research, pH electrodes recommended for biological and pharmaceutical use should have a ROSS and double junction Ag/AgCl reference (no sample contact with silver) or be TRIS compatible. 

Use pH electrodes for biological and pharmaceutical applications and sample preparation specific to DNA, RNA, TRIS buffers, media, buffer preparation, proteins, enzymes, research, and more.

Equip your classroom or academic lab with electrodes our future lab technicians can use every day. For teaching applications, recommended pH electrodes should have an epoxy body for added durability, semester after semester. For advanced academic use, glass-body electrodes can be selected if they fit the application.

Use pH electrodes for academic and student use in general chemistry, water ecology or environmental testing, field use, and more.

Achieving repeatable and reliable sample analysis results through the automated method of titration is key. pH electrodes recommended for use with titration should have a Sure-Flow or sleeve junction for better contact with the samples to provide stable measurements.

Use these pH electrodes when measuring acidity using direct titration, alkalinity, total acidic number, total base number, and for basic R&D work.

As a brewer, winemaker, cheesemaker, or yogurt technician, accurate sample analysis and quality control are essential to your day-to-day functions, ensuring results that meet regulations and product development requirements. pH electrodes recommended for food and beverage applications should have a flat-surface tip and ROSS or double junction Ag/AgCl reference (no sample contact with silver), or a spear tip for piercing samples and a ROSS or double junction Ag/AgCl reference.

Ionic strength is an important factor in many processes. High-ionic-strength solutions change the liquid junction potential; to ensure the best performance with extreme pH and brine sample types, the pH electrodes recommended for use are ROSS Sure-Flow or open junction electrodes.

Use the following pH electrodes when measuring samples with extreme pH or high salt content.

Chemical validation and quality control of air and water in your industrial and chemical applications is essential to your plant’s performance. pH electrodes recommended for use in industrial and chemical applications should have a glass body that resists damage from the sample and a Sure-Flow or open junction to prevent the electrode from clogging and to help provide better contact with the sample. 

Use pH electrodes for industrial and chemical applications specific to chemical validation, quality control and assurance of production, and more.

Sample analysis in quality control and quality assurance labs needs consistent validation for products to meet regulations and product development requirements. pH electrodes recommended for consumer products applications should have a Sure-Flow or open junction to prevent the electrode from clogging.

Use pH electrodes for consumer products applications when testing cosmetics, lotions, oils, baby products, health products, and much more. 

Whether you’re in the field looking for environmental changes or you’re researching sprays and pesticides that affect the general population, real-time sample analysis is vital on-the-go. pH electrodes recommended for environmental applications should have a ROSS or double junction Ag/AgCl reference, an epoxy body for added durability, and be refillable for better contact with the sample.

Use pH electrodes for environmental applications including seawater, rivers, streams, lakes, runoffs, rain water, soil, and more.

Using clean or pure water to dilute and validate samples is essential in an everyday lab setting. Recommended pH electrodes should be ROSS or double junction Ag/AgCl reference and be refillable for better contact with the sample. 

Use pH electrodes for clean and pure water applications during general laboratory measurements for diluting samples and more.
