separator etc., contain liquid biological residues after use that may cause infection.
Handle these components with care and avoid skin contact. To avoid direct contact with biological
materials, always wear appropriate protective equipment such as lab clothing, protective gloves,
safety glasses and, if necessary, a face mask. Additionally a face shield must be worn if there is a
potential of a splashback. Appropriate disinfection and sterilization procedures must be followed.
Always wear gloves when working with the instrument! The tubes may drip a little after being
disconnected. Remove excess fluids with a clean, absorbent cloth.
