Analytical instruments have now achieved a level of accuracy inconceivable years ago.
Many analytical methods require small sample quantities, and the precision of the analysis is greatly affected by the accuracy of the preparation of a representative sample of the material to be tested.
Representative sample division is therefore a basic precondition for precision in particle size analysis, particle sizing, chemical analysis, milling, spectroscopic analysis, trace element analysis and similar applications.
To avoid errors being introduced at the beginning of the analysis process, Laval Lab offers several models of Samples Dividers.
Rotary Sample Splitters are the most accurate equipment for extracting representative samples from dry, granular or powdered material. This type of unit minimizes the negative influences of diverse and extreme differences in grain size, specific gravity, average quality and particle shape.
The Rotary Cone Sample Divider Laborette 27 is a bench-top instrument that can achieve an unequalled division accuracy of 99.9%.
This is the ideal instrument to prepare very small to medium sized analytical samples for spectroscopy, chemical analysis and particle size analysis.
The Rotary Sample Dividers are perfect for precision dividing and sample preparation for large bulk samples, with an accuracy of 99.5%.
They scale up precision dividing and sample preparation for large bulk samples with greatly improved accuracy over traditional riffle splitters. Aggregates, coal, or ores with particle top-size to 2in (50.8mm) are quickly and accurately split to 1/8, 1/4, 1/12 and 1/24 fractions, depending on model, with less handling and risk of sample loss.
The units work equally well for finer granular materials or powders with large volumes, and samples that do not flow well through fixed-chute, gravity riffle splitters.
Riffle Sample Splitters are universally used for rapid and economical sample division.
They are well recognized in the industry and, when used properly, they provide good accuracy.
Sample splitters and dividers provide representative samples of the original or bulk material. This ensures the test sample has materials with particle sizes in equal proportions to the original. Splitter models are available from rugged, large capacity floor units for coarse aggregates, to benchtop models for fine powders.
