The physical properties of the carriers strongly affected the pulmonary deposition of budesonide and the physical stability of the inhalation powder.
Flowlac comes in third position, while Tablettose80 has the lower flowability. The whole measurement is performed easily, fastly and precisely.
The measurement and the result analysis are assisted by software. They are called by the manufacturer Tablettose 70, Tablettose 80, Flowlac 1000 and Flowlac Floqlac prove these assumptions the following figure shows the mass flowrate according to hole diameter: In this study, a novel multiple dose, reservoir-based Taifun was used flowlax a dry powder inhaler, and fowlac effects of carrier physical properties were evaluated on the pulmonary deposition of budesonide, along with physical stability of the inhalation powder.
The GranuFlow allows to plot the full mass flowrate curve. Motion of carbon nanotubes in a rotating fliwlac The characterization methods are related either to the properties of the grains granulometry, morphology, chemical composition, … and to the behaviour of the bulk powder flowability, density, blend stability, electrostatic properties, ….
When compared to an untreated alpha-lactose monohydrate, the highly amorphous spray dried lactose and Flowlac did not improve aerosol performance of the inhalation powder. Although Flowlac 90 and Tablettose70 have the same Cb parameter, Dmin information allows us to affirm that Flowlac90 has the best flowability from all samples and its followed by Tablettose Effect of relative air humidity on the flowability of lactose powdersG.
How tribo-electric charges modify powder flowabilityA. Material The powders used in this application are provided by Meggle Pharma. Flow abilities of powders and granular materials evidenced from dynamical tap density measurementK. Flow of magnetized grains in a rotating drumG.
The GranuFlow is a straightforward powder flowability measurement device composed of a silo with different apertures associated with a dedicated electronic balance to measure the flowrate. Luyten, Powder Technology— Dmin is the minimum aperture size to obtain a flow: This graph shows the good correlation between experimental data and modeled values with Beverloo law.
The Mass Flowrate was investigated for different hole size from 4mm to 16mm. This fact is highly important, because with the Beverloo model, user can make data interpolation, and thus predicts the mass flowrate for different hole sizes.
This flowrate is computed automatically from the slope of the mass temporal evolution measured with the balance. The main purpose of this application note is to provide information regarding lactose analysis for the Pharmaceutical field. Lactose modifications enhance its drug performance in the novel multiple dose Taifun DPI. In this paper, we used a complete set of hole diameters: Lumay, International Journal of Pharmaceutics— The dynamic angle of repose and a bed behavior diagramS.
The aperture size is modified quickly and easily with an original rotating system.

Vandewalle, Physical Review E 70, Cascade of granular flows for characterizing segregationG. These results are really interesting, indeed by the look of Hausner ratio cf. Combined effect of moisture and electrostatic charges on powder flowA. Vandewalle, Powder Technology Vandewalle, Physical Review Letters 95, Measuring the flowing properties of powders and grainsG.
A range of measurement methods has been developed to cover all the needs of industries processing powders and granular materials. Flwlac GranuFlow allows to classify powders in terms of flowability, even if the classical tap density test is unable fllowlac see the Hausner ratio difference.

Vandewalle, Physical Review E 82, R Vandewalle, Physical Review E 81, Dmin is the minimum aperture size to obtain a flow:. However, in this application note, we will be focused on the 010 instrument. Theoretical Framework Granular materials and fine powders are widely used in industrial applications. In this study, untreated commercial preparation of alpha-lactose monohydrate, highly amorphous spray dried lactose, crystallized spray dried lactose, Flowlac and Flowlac mixed with crystalline micronized lactose were used as carriers.
SEM pictures have been made in order to have an information of the particle size distribution and particles shape: All these folwlac are made of lactose. European journal of pharmaceutical sciences: Pirard, Chemical Engineering Journal
