Particle Surface Area Analyzer with Sample Circulation - Acorn Flow by Xigo Nanotools

Based on the Acorn Area™, the Acorn Flow™ measures particle surface area of wetted dispersions, and enables the user to circulate the sample continuously from an external container via a peristaltic pump.

A built-in stirrer allows particles to be kept in suspension whilst in the external beaker, and sample temperature can be regulated using the Peltier regulated controller.

Key Features

The key features of the Acorn Flow Particle Analyzer are:

  • Using the Acorn Flow, the operator can determine the influence of additives such as surfactants and dispersants on the particle-liquid interface of nanoparticle dispersions.

  • The most expensive components in a nanoparticulate dispersion are surfactants and optimization of their concentration is important in maximizing formulation profitability.

  • The relaxation time of the dispersion is altered by the presence of surface active agents on the nanoparticle surface till complete coverage of the particle surface area is achieved.

  • Hence the relaxation time is not changed significantly by the additional surfactant. The Acorn Flow is also invaluable in monitoring other changes at the particle liquid interface, such as flocculation.

  • The Acorn Flow is an ideal tool for use in formulation development in virtually any industry, yet is simple enough for routine use in a quality laboratory.

  • The Acorn Flow temperature controller features a Peltier controlled environment which monitors the sample temperature via the front panel. The front panel membrane keypad is used to set the sample temperature.

  • Measurements with the Acorn Flow are simple and easy.

  • Suspensions and emulsions can be measured non-invasively, without dilution.

  • The proprietary AreaQuant™ software algorithm reports the total measured surface area.
