Rotary cone sample divider Laborette 27
Designed for the representative sample dividing of solids and suspensions with a
dividing precision of 99.9%. The Laborette 27 can also be used to divide liquid media or
suspensions without modification.

Typical areas of use:
Rotary cone sample dividers are ideal sample preparation tools for use with highly accurate analytical instrumentation.
They are used in every research, development and quality control laboratory to prepare small but nonetheless
representative samples for meaningful analysis.
Operational features:
The Rotary cone sample divider Laborette 27 provides the best possible means of sample dividing based on a
combination of 3 dividing processes in one device. The sample is fed through a hopper onto a rotating, dividing cone.
On the surface of the cone, the sample material is accelerated outwards by centrifugal force and divided into
individual streams through guiding channels. Due to the rotation speed and number of dividing channels on the
dividing head, the number of dividing stages reaches up to 3000 per minute, which means that each sample consists
of a very large number of individual samples which is a pre-requisite for good sample dividing.
Performance overview:
- a base unit that can be combined with a choice of 6 dividing head attachments
- up to 3000 dividing stages per minute
- representative sample dividing with an accuracy of 99.9%
- can divide dry samples and suspensions without modification
- choice of various dividing ratios
- quick champing of glass sample bottles
- for optimal sample feeding, the accessory Laborette 24 vibratory feeder is recommended
- safety tested (CE marked)
- 24 month warranty
