S60 HOWARD CELL and K20 COVERGLASS — SV8060 and SV8020
User Notes — SV8060 and SV8020
The Howard cell, a 76 mm x 35 mm glass slide with a central circular island, is used for counting mould fibres and spores in fruit juices, especially from tomatoes. With the K20 coverglass in place a 0.1 mm thickness of liquid is contained over the central island.
Note: The complete system requires both the cell itself (SV8060) and cover glass (SV8020). The cell does not come with a coverglass and one must be ordered separately.
The coverglass has 25 calibrated fields of 1.382 mm diameter through which to view the particles. This coverglass removes the necessity of precise adjustment of the microscope and eyepiece graticule in the original Howard method.
