The Precision Cell
slide has been designed to provide still more accuracy, uniformity
and safety in the microscopic examination of urinary sediment.
Its structure makes the examination still simpler and more
practical, avoiding all possible contamination of samples
and facilitating the counting of the figured elements present
in the urine sample.
Within every chamber there are two series of 9 circles each,
making a total of 18 circles
easily visible at 100x magnifications.
These circles mark off a precise volume of urine and thus
allow calculation, with a simple procedure, of the number
of figured elements present in 1 ml of urine.
