Gentian violet slightly stains the nuclei of the leucocytes. The blood specimen is diluted 1:20 in a WBC pipette with the diluting fluid and the cells are counted under low power of the microscope by using a counting chamber. The number of cells in undiluted blood is reported per cumm (µl) of whole blood.

The 24″ tall, 7 1/4″ diameter tank comes filled with 13 lbs. of our exclusive ion-exchange resins that remove minerals from the water through a process that binds them to the resin. Because the majority of the impurities are dissolved, deionization produces highly purified water, so no more spots! The two valves control the water flow through the filter. This allows you to bypass the filter when it is not needed to prolong the life of the resin. Add our Stainless Steel Quick Disconnect Set for faster, easy use. The life of the resin depends upon the amount of total dissolved solids (TDS) in your water. Want to know your TDS level? Check out our easy-to-use TDS Meter. The replacement resin is safe, disposable, and easy to install.
