Vernier Tris Compatible Flat pH Sensor
Order code: FPH-BTA
VERNIER TRIS COMPATIBLE FLAT PH SENSOR
The Tris-Compatible Flat pH Sensor is highly versatile. Because the glass membrane is flat instead of a bulb, it is more durable, easier to clean and allows for flat surface measurements or smaller sample sizes. It features a sealed, gel-filled, double-junction electrode making it compatible with Tris buffers and solutions containing proteins or sulfides. The flat glass shape also makes it useful for measuring the pH of semisolids such as food or soil slurries.
Requirements:
This sensor requires suitable software and an interface such as one of the Vernier LabQuest variations or Vernier Go-Link.
For comprehensive details of the possible sensor/interface/software combinations see the Compatibility Guide link below.
Specifications:
• Range: pH 0-14 (some sodium error in ranges greater than pH12 due to thicker glass and higher impedance values)
• Electrode type: Double-junction, sealed, gel-filled, Ag/AgCl reference, polycarbonate body
• Membrane style: Flat glass
• Storage solution: pH 4/KCl solution (10gKCl in 100mL buffer pH4 solution)
• Cable: 1m coaxial cable with BNC connector
• Temperature range: 0– 100ºC
• 12 mm OD
• Impedance: ~20kΩ at 25ºC
• Response time: 98% of full response in 30s at 25ºC

This product is used in teaching these Australian Curriculum codes:
ACSSU187 - Chemical Sciences - Chemical Reactions - Different types of chemical reactions are used to produce a range of products and can occur at different rates
ACSBL019 - Biodiversity and the interconnectedness of life - Describing biodiversity - Ecosystems are diverse, composed of varied habitats and can be described in terms of their component species, species interactions and the abiotic factors that make up the environment
ACSBL021 - Biodiversity and the interconnectedness of life - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
ACSBL029 - Biodiversity and the interconnectedness of life - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
ACSPH066 - Linear Motion and Waves - Linear motion and force - Collisions may be elastic and inelastic; kinetic energy is conserved in elastic collisions
ACSPH064 - Linear Motion and Waves - Linear motion and force - Momentum is a property of moving objects; it is conserved in a closed system and may be transferred from one object to another when a force acts over a time interval
ACSPH063 - Linear Motion and Waves - Linear motion and force - Newton’s Three Laws of Motion describe the relationship between the force or forces acting on an object, modelled as a point mass, and the motion of the object due to the application of the force or forces
ACSCH097 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Acids are substances that can act as proton (hydrogen ion) donors and can be classified as monoprotic or polyprotic depending on the number of protons donated by each molecule of the acid
ACSCH101 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Acidbase indicators are weak acids or bases where the acidic form is of a different colour to the basic form
ACSCH096 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Equilibrium position can be predicted qualitatively using equilibrium constants
ACSCH091 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Over time, physical changes and reversible chemical reactions reach a state of dynamic equilibrium in a closed system, with the relative concentrations of products and reactants defining the position of equilibrium
ACSCH100 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The pH scale is a logarithmic scale and the pH of a solution can be calculated from the concentration of hydrogen ions; Kw can be used to calculate the concentration of hydrogen ions from the concentration of hydroxide ions in a solution
ACSCH099 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The relationship between acids and bases in equilibrium systems can be explained using the Brønsted Lowry model and represented using chemical equations that illustrate the transfer of hydrogen ions
ACSCH098 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The strength of acids is explained by the degree of ionisation at equilibrium in aqueous solution, which can be represented with chemical equations and equilibrium constants (Ka)
ACSCH102 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Volumetric analysis methods involving acidbase reactions rely on the identification of an equivalence point by measuring the associated change in pH, using chemical indicators or pH meters, to reveal an observable end point
ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
ACSSU179 - Chemical Sciences - Chemical Reactions - Chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer
