INTENDED USE
2.1.
This centrifuge is a laboratory product designed to separate components by generation
of relative centrifugal force. It separates human and animal samples
–
such as blood,
urine and other body fluids -- collected in appropriate specimen receptacles, either alone
or with reagents or other additives. As a general purpose laboratory centrifuge, it is
designed to also run other containers filled with chemicals (non-flammable, non-
explosive, non-volatile, and non-highly reactive only), environmental samples, and other
non-human body samples. This centrifuge should be operated by trained personnel only.
This centrifuge is an IVD accessory, and therefore subject to the former EU IVD Directive
98/79/EC and the current EU IVD Regulation 2017/746. Any use other than those
intended by the Manufacturer is explicitly prohibited. Maximum sample density is 1.15
grams/mL.
