Rotary Cone Sample Divider LABORETTE 27



  • Guaranteed division accuracy of up to 99.9 %
  • Representative sample division from just a few ml up to 4,000 ml
  • Easy cleaning due to removable dividing head
  • Food-safe materials



    Guaranteed representative subsamples

    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.


    Centric sample feeding

    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.

    Dividing heads for every material

    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.

  • Applications / Solutions

    • 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.
