Correct analysis by representative sample division

A faultless and comparable analysis is closely linked to accurate sample handling. Only a sample representative of the initial material can provide meaningful analysis results. This can be achieved by using a rotating sample divider, such as Retsch’s new PT 100. It divides the sample so exactly that the composition of each of the 6, 8 or 10 fractions corresponds exactly to that of the original bulk sample. This applies both for fine-powdered and coarse materials up to 10 mm feed size. The material feed and dividing processes take place automatically and without loss of material. The new rotary tube divider PT 200 (Fig.) allows for the representative, dust-free division and reduction of larger volumes of bulk goods. The ratio of the fractions is freely adjustable. Both dividers feature digital time setting and comfortable quick-release clamps.
