The Falcon Tube is a glass or plastic tube made of polypropylene (PP) with different volumes (usually 15 ml and 50 ml) with a screw with high strength and accuracy, which is located exactly in the rotating holes of the centrifuge. Takes. These tubes are highly PCF tolerant, autoclave-resistant and resistant to most organic solvents. Their capacity can vary greatly from 50 ml to much lower capacity in microcentrifuges, which are mostly used in biomolecular laboratories. The conical end of this product is one of its advantages when only a small amount of liquid remains in their container. Under these conditions, all liquid droplets can be easily collected by centrifugation.
