<p>There is described an apparatus and method which permits accurate weighing and/or measuring of solid particulate matter. The invention may be utilised to enable a hollow structure (1) such as a container (for example a tube) to be at least partially filled with a pre-determined volume or weight of solid particulate matter, such as powder, in an accurate and reproducible manner. In particular there is described a method of measuring out a specific volume and/or weight of particles. The method comprises the up-take of a pre-determined amount of particles into a transfer vehicle (4), movement of the particles into the tranfer vehicle (4) being controlled by pressure (5, 6); and the volume of the transfer vehicle (4) dictating the amount of particles taken up. In this manner a specific volume of particles may be accurately taken up into the transfer vehicle (4) and the volume may be calculated to give a certain weight of particles, depending on the density of the particles in question. The particles taken up in the transfer vehicle (4) may be expelled therefrom, when required, by alteration of the pressure (5, 6).</p> |
