General Laboratory and Field Samples
- Plastic-body pH electrodes, either refillable or gel-filled, are ideal for field measurement.
- The glass membrane of refillable electrode offers excellent response to low conductivity water. When the refilling port is covered with the movable slider, the electrode can be used in submerged measurements for up to 30 minutes in 1m depth of water.
- Gel-filled pH electrode does not require refilling.
- ToupH electrodes are more impact-resistant than conventional glass-body pH electrodes due to their thick glass membrane. These electrodes are recommended for general laboratory samples.
Precise Measurement
- High stability is required for precise measurement.
- The folllowing electrodes have glass membrane that is highly sensitive to low conductivity water and non-aqueous solvents. A movable sleeve is used at the liquid junction for easy cleaning and clog-free measurement.
Less Volume Samples
- The volume of sample must be enough to cover the glass membrane and liquid junction of the pH electrode during measurement.
- ToupH electrodes are constructed with thick glass membrane, that is highly resistant to impact and chemicals.
- Long pH electrodes, come in 3mm and 8mm diameters, are suitable for test tubes and tall containers while micro pH electrodes with 3mm diameter are perfect for small tubes and trace amount of samples.
Low Conductivity Samples
- pH measurement of low conductivity samples such as pure water and non-aqueous solvents can be very challenging.
- The glass membranes of the following pH electrodes produce excellent response in the abovementioned samples.
Solid and Semi-solid Samples
- Needle-type pH electrode can be used to pierce and penetrate solid samples, such as meat, fruits, and food samples during measurement.
- Flat pH electrode and ISFET electrode are ideal for surface pH measurement of moisture-containing solids such as nutrient agar, skin, cloth, leather, paper, meat, and leaves.
- ISFET electrode can also be used in food processing and other applications where glass is prohibited.
