Rotary Cone Sample Divider

Rotary Cone Sample Divider LABORETTE 27

The ideal solution for preparing the representative samples for your laboratory, the FRITSCH Rotary Cone Sample Divider LABORETTE 27 can divide your samples with up to 3,000 dividing steps per minute through a rotating dividing cone up to 30 separate channels. It can achieve a 99.9% accuracy for dividing the samples compare to any other similar method.


  • Microprocessor control and digital display of all functions
  • RS232 interface can control all functions - interface and AUTOSIEVE allow inspection of the sieving process via an online comparison of the set and actual amplitude
  • AMPCONTROL for setting guaranteed constant amplitude meaning precisely reproducible sieving results in accordance with DIN 19683
  • Programme selection for storing up to 10 individual sieve programmes
  • Intermittent mode for sieving low density voluminous material reducing sieving time
  • Micro-mode and micro-intermittent mode for micro sieving of fine materials 5 Μm to 100 Μm
  • Energy-saving mode - the instrument switches automatically to standby
  • Including FRITSCH warp-free EASYTWIST sieve stack tensioner
  • Intelligent wet sieving with wet sieving lid with 2 rotation nozzles
  • Modular system for wide-ranging application options
  • Convertible to Vibratory Micro Mill PULVERISETTE 0
  • Optimum power consumption prevents warming up of the sieving system
  • Sieving parameters are entered via ergonomically installed soft touchpad with digital display
  • Up to 10 test sieves can be used simultaneously per working cycle - allowing up to 5 sieving operations to be performed at the same time
