• For many applications, particularly where larger plankton are being analysed, there is no requirement for a counting grid printed onto the slide, hence the introduction of this slide with a plain glass base. This chamber can be used with either upright or inverted microscopes.

• The glass base is 75mm x 40mm x 2mm thick and the Stainless steel frame traps a cell volume of 1.0ml when the cover glass (supplied) is placed over it. The preparation and filling method is exactly the same as the S50 and S52 gridded chambers.

Important Note. Lugols, the compound that is often used in these analyses, is very aggressive. It is best to keep the time that lugols spends in the chamber to a minimum and then it should be washed out promptly and thoroughly using normal laboratory soap solutions. Do not use heat in the analysis or drying process.
