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 modification 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.

Outmoded division principles such as „quartering“ or „coning“ no longer satisfy the requirements of modern analysis methods.

The best possible sample division is based on a combination of three division processes in a single instrument:

The sample is fed through a funnel to a division cone with a shape that corresponds to quartering and coning. Against the surface of the cone, the sample material is accelerated outward through rotation of the entire system and divided by guide channels into 30 individual material flows. The individual samples are collected in glass screw cap bottles.

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 %.

• A base instrument, combinable with 6 different dividing heads
• Up to 3,000 division steps per minute
• Representative sample division, samples divided with an accuracy of 99.9%
• Division of dry samples and suspensions without modification of the instrument
• Variable division ratios
• Quick clamping of the 250 ml and 500 ml glass sample bottles as a standard feature
• Adapted sample division with the vibratory feeder LABORETTE 24
• Collecting vessels of glass available in a size range from 15 ml to 500 ml
• Certified safety (CE mark)
• 2-year warranty

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.
