Blood collection tools that hematologists use vary depending on the job, explains The Nest. For example, a hematologist drawing blood from a vein uses a tourniquet, needle and test tube. On the other hand, blood collection from a finger calls for a lancet and test tube. Common blood collection tools include alcohol and bandages.

Blood analyzers help hematologists assess blood for factors such as coagulation, blood count and erythrocyte sedimentation rates, says The Nest. A cell counter can be electrical or optical, and hematologists use it to measure, categorize and describe the cells in a sample of blood. For example, when someone wants to know the count of red and white blood cells, a cell counter gives the answer. Erythrocyte Sedimentation Rate analyzers look at inflammation and reticulocyte counts.

Reticulocyte counts analyze how fast the red blood cells called reticulocytes are created and released, explains WebMD. They are helpful in conditions such as hemolytic anemia.

Microscopes and cell image analyzers assist hematologists in getting an up-close look at blood at the cellular level, says The Nest. Automated systems at blood banks screen for blood type and illnesses such as HIV.
