RPM vs RCF. This is how centrifuge manufacturers generally describe how fast the centrifuge is going. The rotor, regardless of its size, is revolving at that rate. The force applied to the contents varies by the size of the centrifuge rotor. RCF (relative centrifugal force) is measured in force x gravity or g-force. This is the force exerted on the contents of the rotor, resulting from the revolutions of the rotor. It is RCF, not RPM that separates aqueous solutions in the centrifuge. RPM can be calculated for any centrifuge by this equation:
Q1. Medium Density Fibreboard (MDF) is an engineered wood-based sheet material made by bonding together wood fibres with a synthetic resin adhesive. MDF is extremely versatile and can be machined and finished to a high standard. First, try to reduce risks at source where possible by using a lower risk alternative, where one exists. 2  An example of this could be to use a âno added formaldehydeâ MDF board or low-emission MDF board if practicable to do so. 3  There should be an effective dust extraction system in use whenever MDF is machined or sanded.
