Autofilt Semi Automatic Filter System
Sample Preparation for Sugar Analysis

Introduction to the AutoFilt system

The standard procedure to separate particles from a solutions is a gravimetric filtration. This method is time consuming and can result in small amounts of evaporation of the liquid. In the sugar laboratory the automatic filtration systems AutoFilt reduces the filtration time by at least a factor of 10 and ensures a turbidity free solution in a very short time. The AutoFilt filtration system is specially designed to speed up sample preparations for the polarimetric analysis of sugar solutions using Near Infra Red polarimeters (Saccharimeters). The AutoFilt obviates the need to clarify sugar and avoids the use of lead acetate and aluminum sulfate.
The unit comprises a sample compartment, with filter holder, a pump, and a stand to hold the sample chamber and collect the filtrate. The unit operates with compressed air which is provided by a small compressor (or central air). The compressed air forces the liquid in the sample holder through a filter and into the filtrate collection flask. The operation is automated with the push of a button
