L-27
Sample division with up to 99.9% accuracy for representative analyses
The FRITSCH L-27 sample divider guarantees representative sample division with an accuracy of up to 99.9%. This compact benchtop unit precisely divides samples ranging from 5 mL to 4,000 mL into up to 30 identical units with exactly the same chemical and physical properties—the foundation for reliable analytical results in the laboratory and quality assurance.
Centric sample feeding for maximum division accuracy
The L-27 utilizes the rotating cone principle for maximum precision: The feed hopper directs the sample material centrally onto the tip of the rotating cone. On its surface, the material is accelerated outward by the rapid rotation and divided into sub-samples that are chemically and physically identical through up to 30 guide channels. For the subdivision of liquid samples, the hopper is simply repositioned for eccentric subdivision—without any time-consuming modifications.
Material-Dependent Adjustment and Variable Rotational Speed
A key advantage is the ability to adjust operating parameters based on the material. Rotation speed, timer, and feed rate can be specifically tailored to the physical and rheological properties of the sample material—such as particle size, density, or moisture content. The variable speed range of 80 to 120 rpm ensures that different bulk materials are processed under optimal conditions and that every particle has an equal chance of being included in the sample. The result is statistically reliable samples that are reproducible at any time.
Variable division ratios for every need
With division ratios of 1:8, 1:10, or 1:30, as well as up to 3,000 division steps per minute, the L-27 is suitable for a wide variety of applications. The device can operate either continuously or via a timer, thereby ensuring standardized sampling processes under consistent conditions. This improves the comparability of measurement series and increases process reliability in everyday laboratory work.
Customized Sample Distribution
To ensure a uniform material feed, the sample divider can be combined with the L-24 distribution chute. The automatic control of material conveyance reduces flow-related fluctuations and improves the reproducibility of results, particularly with challenging bulk materials.
Comprehensive Equipment for a Wide Range of Applications
Seven different sample heads made of POM, anodized aluminum, or PTFE-coated aluminum allow for optimal adaptation to a wide variety of materials with a maximum feed size of 2.5 mm or 10 mm and a maximum sample volume of 300 ml, 2,500 ml, or 4,000 ml, depending on the configuration. Various collection vessels ranging from 15 ml to 500 ml are available, all of which can, of course, be easily cleaned in the dishwasher. Thanks to its wide-range power supply, the L-27 operates worldwide regardless of the local mains voltage and delivers identical operating conditions everywhere.
The L-27 sample divider, with its combination of maximum division accuracy, flexible material adaptation, and intelligent process control, offers optimal conditions for representative and standards-compliant sample preparation.
