ApplicationFor determination of the specific surface (Blaine value) of powders, especially suitable for the permanent control of manufacturing characteristics in the daily laboratory work. This measuring procedure serves as practice oriented alternative for the standard procedure according to DIN EN 196-6 as well as ASTM C 204.

Advantages - an alternating operation with two load cells enables

higher test frequency

- immediate readout of the specific surface on the apparatus

- height adjustable optical sensors for optimal results for the different samples to be tested

- density, initial weight and porosity selectable acc. to the specific samples

- calibration via reference materials

- five different calibration factors savable

- runtime indication resolution : 0.01 sec

- calculation of the Blaine values incl. standard deviation of up to 99 samples

- connection to balance, dial gauge and printer are available as options

- improved accuracy as one can select tests as much as desired for one sample; the average value is always calculated by the software

- Blaine value calculation is adaptable to the tempera-ture by a built-in sensor

- the possibility of „zero“-test avoids measuring errors because of selfcompacting of the powder

- connection to PC for data exchange to LIMS and other laboratory data recording systems through the universal file interface software ToniDAT

DesignThe device consists of a microprocessor control unit and a housing with measuring unit. Via magnet valve and membrane pump, a vacuum is achieved by using an U-tube manometer with contactless, adjustable, optical level sensors. This vacuum will be balanced by the air stream through the powder bed in the permeability cell.

Working PrincipleUsing the plunger the powder will be compac-ted within the permeability cell to a defined volu-me. (with an optional electronic dial gauge, the Blaine value can be corrected to the actual volume). After placing the filled permeability cell and entering the samples data for the specific test into the control unit the test will be automatically performed and evaluated. The Blaine value is calculated as average value of the values measured in the single cell according to recent standards (e.g. DIN EN 196-6, ASTM C 204).
