Much like a car, scientific instruments may need a bit of care to keep them working reliably and at their most accurate. ? The Allschoolabs Service Department have over 60 years experience in scientific instrumentation. We have a number of highly qualified internal and field-based service engineers able to perform a variety of jobs including preventative maintenance servicing and calibration. Allschoolabs can offer yearly service contracts which include two main types of preventative maintenance/calibration services ? the back to base service and an engineer visit to your site. These options are can be offered with differing turn around times depending on the instrument type and your requirements along with loan instruments if available. ? A typical preventative maintenance service includes the following: Inspection and testing of the unit Dismantling, cleaning and inspection of the key parts Correction of minor defects including adjustments if necessary Reassembly and testing Take post adjustment / cleaning readings Supply of calibration certificate Return of the item to you (back to base services) ?

Horiba Electrode Selection General Laboratory and Field Samples Plastic-body?pH electrodes, either refillable or gel-filled,?are ideal for field measurement.? The glass membrane of refillable electrodes offers an 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 a 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. Examples below: 9651-10D (for field-testing) 9625-10D (for general-purpose use) 9615S-10D Standard ToupH electrode (for general laboratory application) 9415-10C Standard ToupH electrode (for general laboratory application) Precise Measurement High stability is required for precise measurement. The following electrodes have glass membranes 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. 9481-10C Sleeve ToupH electrode (for viscous and non-aqueous samples) 9681S-10D Sleeve ToupH electrode (for viscous and non-aqueous samples) 6367-10D (for high accuracy pH measurement) Smaller Volume Samples The volume of the sample must be enough to cover the glass membrane and liquid junction of the pH electrode during measurement. ToupH electrodes are constructed with a thick glass membrane that is highly resistant to impact and chemicals. Long pH electrodes, which come in 3 mm and 8 mm diameters, are suitable for test tubes and tall containers, while micro pH electrodes with 3 mm diameter are perfect for small tubes and trace amounts of samples.? Examples below: 9618S-10D Micro ToupH electrode (for low-volume samples) 9418-10C Micro ToupH electrode (for low-volume samples) 9680S-10D Long ToupH electrode (for large containers and long tubes) 9480-10C Long ToupH electrode (for large containers and long test tubes) 6069-10C (for very slender test tubes) 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 an excellent response in the above-mentioned samples. 9481-10C Sleeve ToupH electrode (for viscous and non-aqueous samples) 9681S-10D Sleeve ToupH electrode (for viscous and non-aqueous samples) 9630-10D (for low conductivity samples) Solid and Semi-solid Samples Needle-type pH electrodes can be used to pierce and penetrate solid samples, such as meat, fruits, and food samples, during measurement. Flat pH electrodes and ISFET electrodes are ideal for surface pH measurement of moisture-containing solids such as nutrient agar, skin, cloth, leather, paper, meat, and leaves.? ISFET electrodes can also be used in food processing and other applications where glass is prohibited. 6252-10D (for food samples) 6261-10C (for flat surface measurement) Request Information...

Traditional glass pH electrodes are very delicate and need regular care to keep them in good working order. If your electrode has been damaged by exposure to incompatible chemicals such as proteins, heavy metals or sulphides, you may be able to clean and revive it using specialized cleaning solutions...
