An efficient sample preparation technique is a pre-requisite in all kinds of analysis because any errors will be reflected in the results later on and impact the whole experiment or process. Hence, guaranteed representative sub-samples play an important role in today’s applications.

The FRITSCH Rotary Cone Sample Divider LABORETTE 27 offers the most accurate way of sample division. It is the only sample divider on the market which is capable of dividing samples with up to 3,000 dividing steps per minute. In addition, the sample delivery funnel guides the sample material precisely centred on the tip of the rotating cone for more precision during sample 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 and 1:10 - are available for materials and suspensions with abrasive properties. For especially aggresive solids and suspensions, the resistant PTFE-coated aluminium dividing head 1:30 is also available.
