See how you can effectively combine the the FRITSCH Rotary Cone Sample Divider LABORETTE 27 with the FRITSCH Vibratory Feeder Laborette 24 to create a representative sample. 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. Both models of the FRITSCH Vibratory Feeders LABORETTE 24 are ideal for automatic, uniform feeding of free-flowing materials into sample dividers, mills, mixers, sieve shakers, balances and other laboratory instruments. The vibration, which is controlled by a microprocessor, conveys the sample material out of the funnel over the V or U-shaped stainless-steel channel into the respective equipment. The flow rate can be individually adjusted; the vibration amplitude is precisely controlled, for absolute uniform feed of even smallest quantities.
