Rotina 420 R

ROTINA 420 R :

The ROTINA 420 R maintains the set temperature to safeguard the integrity of samples.  It can handle high numbers of samples, yet is compact and integrates well into the laboratory. It has a high performance where it counts and is extremely economical. It will provide many years of reliable operation and therefore offers an excellent ratio of price to performance.

The ROTINA 420 R can handle large volumes. Its maximum capacity of 4 x 600 ml, 140 blood collection tubes or 16 microtitre plates makes it exceptionally suitable for use in medical diagnostics (clinical chemistry). It is also a reliable tool for long term use in biotechnology and pharmaceutical research laboratories.

The temperature of the centrifuge can be set to any value in the range -20 °C to +40 °C. The temperature can also be set in Fahrenheit. If toxic or infectious material is centrifuged, then the TÜV-tested accessories with bioseals can protect against aerosols.

Information is available on request on versions such as the model with connection for nitrogen flushing (catalogue No. 4706-20), and a heating and cooling version for temperatures up to 90 °C (catalogue No. 4706-50).
