For representative sample division of solids and suspensions with a division accuracy of 99.9%.
Rotary Cone Sample Dividers form a symbiosis with high-precision analytical measurement instruments. They are used in every laboratory involved in research, development and process monitoring in order to produce small yet nevertheless representative sample quantities for accurate analysis results.
With the models of the Rotary Cone Sample Divider LABORETTE 27, even liquid media or suspensions can be divided without conversion of the instrument. In the division of suspensions with coarse-grained portions in particular, division with the Rotary Cone Sample Divider avoids the disruptive influence of demixing due to sedimentation of larger or heavier particles.
Traditional dividing methods such as quartering and coning no longer provide enough accuracy for high-precision modern analytical instruments.
The best possible sample division is based on a combination of three division processes in a single instrument:
The sample feed funnel of the LABORETTE 27 guides the sample material centred onto the point of the rotating cone. The rapid rotation of the entire system accelerates the sample material outwards along its surface and divides it through up to 30 guiding channels into chemically and physically precisely identical subsamples. The individual samples are collected in glass screw cap bottles. For the division of liquid samples, the funnel is simply repositioned for eccentric division.
Due to the rotation and the number of division channels of the dividing head, the number of divisions is increased up to 3,000 division steps per minute, meaning that every sample consists of a very large number of individual samples - the hallmark of precise sample division. As a result of its design, the Rotary Cone Sample Divider LABORETTE 27 can divide samples with an accuracy of 99 %.
The standard equipment delivered with the Rotary Cone Sample Divider does not include the dividing head. Dividing heads with various division ratios (1:8; 1:10; 1:30) and in various materials are offered. The corresponding dividing head must be ordered as an accessory.
The precision of the division is further increased by the use of the Vibratory Feeder LABORETTE 24 through the slow, even supply of material. In this way, even materials that do not flow easily, such as cement or limestone.
