How does Countess count cells?
The Countess™ automated cell counter uses state-of-the-art optics and image analysis to automate cell counting. The Countess™ automated cell counter is a benchtop counter designed to measure cell count and viability (live, dead, and total cells) accurately and precisely, using the standard trypan blue technique.
What is a automated cell counter?
Automated cell counters are machines that automatically count cells. Used in medical and research labs, automated cell counters can be used on blood or urine samples to determine the number and types of cells present or to check the viability of a cultured cell line for research purposes.

How do you use Countess?
To use the Countess, simply combine 10 uL of trypan blue with 10 uL of cells. Mix and add 10 uL of mixture to one side of the disposable cell counting chamber slide. Insert the slide into the allotted slot on the front of the machine. The image of the cells will immediately appear on the screen.

What are the two types of automated cell counters?
Coulter counters are particle counters based on electrical impedance. As the liquid containing cells or other objects is drawn through a small aperture, it causes a change in electrical impedance proportional to the size of the particles.
What are the advantages of automated cell counter?
Existing automated cell counters have the advantage of largely removing human subjectivity from the cell counting workflow. They are also often faster than counting manually and can count a larger number of cells, increasing statistical accuracy.
What is the principle of cell counter?
Coulter Principle
The traditional method for counting cells is electrical impedance, also known as the Coulter Principle. Whole blood is passed between two electrodes through an aperture so narrow that only one cell can pass through at a time. The impedance changes as a cell passes through.
How does Cellometer work?
How does the Cellometer software count clumpy cells? The Cellometer software recognizes the bright centers of viable cells within clumps. Clumps can be de-clustered to count individual cells or remain counted as one, depending on the user’s selection.
