LABOID LBM-91 Blood Tube Roller Mixer – 4 Roller, 30–36 RPM, Brushless DC Motor

The LABOID LBM-91 Blood Tube Roller Mixer is a compact laboratory mixer designed for the gentle and continuous mixing of blood samples and other liquids contained in tubes or bottles. LABOID's blood tube roller platform uses a rolling and rocking motion to maintain homogeneous samples without the vigorous agitation associated with vortex mixing. The LBM-91 features 4 rollers operating at approximately 30–36 RPM and is powered by a brushless DC motor, providing smooth, quiet and low-maintenance operation. Its gentle mixing action makes it particularly useful for blood samples where consistent mixing of cells and anticoagulants is required before analysis. The compact benchtop design makes the mixer suitable for haematology laboratories, hospitals, blood banks and diagnostic centres, especially for routine preparation of blood tubes prior to testing.
