Blood Roller Mixer

A blood roller mixer has a set of rollers that rotate or rock to gently move tubes placed on top. When blood is drawn into collection tubes with anticoagulant, it must be mixed slowly and continuously so the anticoagulant spreads evenly throughout the sample and prevents clotting. The roller mixer does this by holding multiple tubes in place and rotating them at a controlled speed.

It is commonly used for:

• Mixing blood samples before analysis (e.g., for RBC, WBC, platelet counts)

• Preparing samples for hematology and clinical testing

• Handling viscous liquids and suspensions where minimal aeration is needed

• Mixing reagents and other laboratory liquids in tubes or bottles
