Filter holders

Special glassless sample carrier plates are available for mounting a prepared filter paper on to the Morphologi G3 instrument. Their special design ensures the filter paper is stretched flat, which is essential for automated analysis.

The filter holders allow two filters to be presented to the instrument and therefore analyzed successively without any manual intervention.

Glassless carriers eliminate the risk of particles on the glass surface being counted, they prevents particles from being crushed by the glass and simplify cleaning requirements. However, glass slide carriers are also available for cases when a sample preparation procedure has been developed using this method.
