ANALYSIS

OVERVIEW

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.

WORKING PRINCIPLE

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.

FEATURES
  • Extra strong 2.2 kW drive power and extremely high centrifugal acceleration up to 64 g and up to 800 rpm (rotational speed of the bowl 1,600 rpm)
  • Maximum operational safety due to ServoLOCK clamping of the grinding bowls
  • Blocking of the mill in the event of impermissible operating states
  • Automatic shutoff function if an imbalance occurs
  • Reliable bowl detection via RFID chip and optimization of grinding speeds via RFID-Chip
  • Safely guided insertion of grinding bowls
  • Safe opening in the event of overpressure
  • Intuitive touchscreen operation with colour display
  • Simultaneous processing of up to 4 samples
  • Useful capacity  up to 2 x 225 ml
  • Up to 8 programmes can be saved, software MillControl (optional), USB inter face for transmission of process parameters
  • Extensive accessories for simplifying your daily work
 
 
EQUIPMENT / ACCESSORIES

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.

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.

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.
