USA E8 Combination Centrifuge
The E8 Combination Centrifuge is specifically designed to run 75mm microhematocrit tubes and 1ml-15ml microtubes and test tubes. This centrifuge features quiet operation for a more peaceful laboratory environment. It also features a shorter height to fit under any cabinet, and auto-calibrating speed function for precision results.
To run microhematocrit tubes, simply insert your 75mm capillary tubes into the carrier, place carriers in opposing tube sleeves for a balanced load, and spin at 3,500 rpm for 6 minutes for clear separation.

Microhematocrit PCV Procedure
3 Easy steps to achieve accurate PCV results:
- Insert capillaries in the Crit Carrier
- Insert the carrier in the metal tube sleeves
- Spin at 3,500 rpm for 6 (+/-1) minutes
Angled Rotor Technology
In a traditional microhematocrit centrifuge with a flat rotor, the red cells and the plasma must pass through each other horizontally in the narrow tube. In this case, very high speed and g-force is needed to reduce trapped plasma. When using LW Scientific Crit Carriers in an angled rotor, the red cells initially move to the outer tube wall while the plasma initially moves to the inner tube wall. Then, they pass each other easily as the red cells travel down to the bottom of the tube and the plasma travels to the top. With more efficient separation and ZERO trapped plasma, the PCV value will be accurate.
The E8 Combination Centrifuge is a FDA registered, Class II medical device. Comparable results to the HemataStat II angled PCV centrifuge sold to the human market. The HemataStat II produces PCV results at 2,000 g-force in 1 minute.
