LABORETTE 27 Rotary Cone Sample Divider
A perfect sample preparation is the indispensable foundation for every analysis – because any errors will be reflected in the results later on. Therefore the reliable creation of guaranteed representative subsamples plays an absolutely central role. The FRITSCH Rotary Cone Sample Divider LABORETTE 27 offers the ideal conditions: it is the only sample divider on the market dividing your samples with up to 3,000 dividing steps per minute centred over a rotating dividing cone into up to 30 separate channels. Each individual sample with identical chemical and physical properties – and with 99.9 % accuracy for many more sample materials than any other similar method. The best sample division, possible today. เครื่องแบ่งตัวอย่างอัตโนมัติ

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. Your advantage: greatest division precision during sample division for the best possible accuracy and representative samples. For the division of liquid samples, the funnel is simply repositioned for eccentric division.

Select exactly the right dividing head for your LABORETTE 27 as an accessory according to your application in the division ratios of 1:8; 1:10 or 1:30 made of stable POM plastic. Anodised aluminium dividing heads – 1:8 and1:10 – are available for materials and suspensions with abrasive properties. And for especially aggressive solids and suspensions, the resistant PTFE-coated aluminium dividing head 1:30 is also available.
Each dividing head of the LABORETTE 27 is delivered with a funnel of 10 mm diameter, the dividing heads with division ratios of 1:30 are additionally supplied with a 5 mm funnel. There are also funnels of 15 mm and 22 mm diameter for perfect adaptation to the respective particle size available. Special funnels for suspensions are also available.
FRITSCH also delivers glass collecting vessels in different sizes from 15 ml to 500 ml for up to 4 litres total volume – dishwasher-safe and therefore particularly easy to clean.
Also available are our specially developed plastic inserts with 32 ml volume for insertion into the 250 ml and 500 ml sample bottles for smallest quantities.

SAMPLE DIVISION AS A BASIS FOR MODERN ANALYTICAL METHODS
Instruments used to measure particle size have now achieved a degree of accuracy which was inconceivable years ago. Tolerances are constantly being reduced and the latest versions on the market operate faster and more accurately than their predecessors.
NEW APPLICATIONS FOR FRITSCH LABORATORY INSTRUMENTS
The directives 2003/108/EC (WEEE) and 2002/95/EC (RoHS) of the European Union have opened up new applications for FRITSCH Laboratory Equipment.
CRUSHING CONCRETE COARSELY AND FINE
Concrete is a complex material, which its characteristics due to its composition and as a result of the systematic addition of additives can be adjusted very differentiated. However, this results in the demand to monitor this composition for two reasons: in order to ensure the desired useful properties and also to ensure the quality of the mixture.
ANALYTICAL DETERMINATION OF CRUDE FIBRE IN ANIMAL FEED
Even animal feed is sold with a declaration about its contents. For quality assurance those substances of contents are continually examined.
SALT, SODIUM CHLORIDE, POTASSIUM CHLORIDE
A prerequisite for an efficient salt extraction and processing is the exact knowledge of the mineral compositions of in-situ evaporates, as well as their chemical composition and also of the accruing intermediate and final products during the manufacturing process.
SAMPLE PREPARATION FOR REFUSE DERIVED FUELS
Plastic, wood and shredded waste, are in times of rising crude oil prices very interesting additions to the classic fuels. Especially in the cement industry, the energy rich fractions from conditioning processes are readily burned along. Important here is the analytical evaluation of the materials.
