PRECISION CELL
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 cell counting 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 magnifi cation.
These circles mark off a precise volume of urine and thus allow calculation, with a simple procedure, of the number of cells present in 1 ml of urine.

PRECISION CELL
Procedure for 10 ml of urine sample after centrifugation:

• after having suffi ciently stirred the urine sample, pour 10 ml into a conical test tube (REF 18304);
• centrifuge for 5 minutes at 400g or 1500 rpm;
• pour off 9 ml of the top fl uid;
• suspend the sediment again, suffi ciently stirring the test tube;
• remove the suspension with a Pasteur pipette and fi ll the chamber in the slide;
• locate the grid at 100x magnifi cation and read at 400x magnifi cation;
• multiply by 1000 the total number of cells counted in one of the two series of 9 circles.

The value thus obtained indicates the number of cells present in 1 ml of urine.
Procedure for 12 ml of urine sample after centrifugation:

• after having suffi ciently stirred the sample of urine, pour 12 ml into a urine test tube (REF 18159);
• centrifuge for 5 minutes at 400g or 1500 rpm;
• pour off 11 ml of the top fl uid;
• suspend the sediment again, suffi ciently stirring the test tube;
• remove the suspension with a Pasteur pipette (code 18434) and fi ll the chamber in the slide;
• locate the grid at 100x magnifi cation and read at 400x magnifi cation;
• multiply by 833 the total number of fi gured elements counted in one of the two series of 9 circles.

The value thus obtained indicates the number of cells present in 1 ml of urine.
