VERNIER GO DIRECT DROP COUNTER
Vernier's Go Direct Drop Counter precisely records the number of drops of titrant added during a titration and then automatically converts it to volume. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

Conducting a titration has never been easier. Use the Vernier Go Direct Drop Counter in conjunction with other Go Direct sensors, such as Go Direct pH, Go Direct Conductivity or Go Direct ORP, to perform acid-base, conductometric or potentiometric titrations.

Designed with a wide drop-detecting area, Go Direct Drop Counter removes the need for precise burette alignment. Vernier has also included a large sensor slot for conventional stick-style sensors and a smaller, adjustable slot for temperature probes. The adjustable clamp easily fits the Vernier Stir Station and most laboratory ring stands and lattices.

    This product is used in teaching these Australian Curriculum codes:
    ACSCH063 - Molecular interactions and reactions - Aqueous solutions and acidity - The concentration of a solution is defined as the amount of solute divided by the amount of solution; this can be represented in a variety of ways including by the number of moles of the solute per litre of solution (mol L­1) and the mass of the solute pe
    ACSCH066 - Molecular interactions and reactions - Aqueous solutions and acidity - The pH scale is used to compare the levels of acidity or alkalinity of aqueous solutions; the pH is dependent on the concentration of hydrogen ions in the solution
    ACSCH064 - Molecular interactions and reactions - Aqueous solutions and acidity - The presence of specific ions in solutions can be identified using analytical techniques based on chemical reactions, including precipitation and acid­base reactions
    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
    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
