HERMLE – Universal Centrifuge & Large Volume Centrifuge – Z 446 K
These high-volume centrifuges Z 446 and Z 446 K achieve a throughput of 68 x 15 ml conical tubes or 28 x 50 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 10 x 50 ml. The fixed-angle and swing-out rotors are suitable for almost all aplications in everyday use in clinical, industrial and research laboratories.

Brand
Since 1956 – for more than 50 years – HERMLE centrifuges are being sold to all parts of the world. Once a division of Berthold Hermle AG in Gosheim, HERMLE Labortechnik GmbH in Wehingen is a company of its own since the end of 1993. The whole production program has been entirely renewed during that time. Each unit stands for efficiency, versatility and easy handling. In the meantime our centrifuges are welcome in the fields of medicine, research and industry. A wide range of rotors is available for the different models. All centrifuges are equipped with a microprocessor and a maintenance-free direct current motor. The refrigeration system is of course CFC-free.
