These high-volume centrifuges Z 446 and Z 446 K achieve a throughput of 68x15 ml conical tubes or 28x50 ml conical tubes at a max.RCF of 3434/4346 xg.

If higher speeds are required, we also offer e.g. an angle rotor with a max. RCF of 14532/16022 xg for 10x50 ml. The fixed-angle and swing-out rotors are suitable for almost all aplications in everyday use in clinical, industrial and research laboratories.
