German company Colloid Metrix is a professional research and manufacturing instrument company that specializes in characterizing alternating features.In terms of colloid formula analysis, CMX's Stabino, Zeta check, and Nano Flex provide users with a new measurement method for flow/Zeta potential and particle size. At the same time, Stabino combined with Nano Flex also provides multiple titration functions, which can achieve the measurement of particle size and Zeta potential changes as well as isoelectric point in salt solutions and polyelectrolyte solution systems with different pH values and concentrations.

Instrument Introduction:

Zeta Check This instrument has andThe measurement principle of Stabino II is the same, but the difference is that Zeta Check cannot automatically change the environment of the solution and can be operated independently without the need for a computer. The instrument can automatically save data up to 1000, and can also read data with a computer or connect to a printer to print data. The data measured each time includes the record number, time, and measured potential value. (Unit: MV)

The core of Zeta Check is a cylindrical PTFE cavity and an oscillating piston. By moving the piston up and down in the cylindrical cavity, the liquid between the cavity and the piston will move up and down. Due to the shear force at the interface of solid particles, the ion cloud of the double layer of the particles moves, and the static state of the particles is formed by the adsorption of large molecules or small particles on the wall of the cavity or the inertia of large particles. And in the stationary zone at the bottom of the sample, there is no such ion displacement. Therefore, the oscillation signal between the bottom and higher parts of the measurement cavity can be measured. That is, the flowing potential (SP). The flow potential is directly proportional to the Zeta potential of the particles.
