MSE have always had an enviable reputation for their bench top centrifuges and the HARRIER range continues this tradition. In addition to the existing HARRIER 15/80, the HARRIER 18/80 REFRIGERATED is designed for routine laboratory use and has the additional facility of being able to centrifuge samples at sub–ambient temperatures. Both centrifuges represent excellent value for money in terms of performance, ease of use, safety and reliability.

Automatic rotor identification system

The HARRIER range incorporates an automatic rotor identification system. This important feature ensures that the centrifuge recognises the rotor in use and prevents it from being used beyond its safe maximum speed. As the centrifuge identifies the rotor in use, it can also work out the ‘g’ force at any set speed. This means the centrifuge can convert rpm to ‘g’ and vice versa once in use.

Microprocessor controlled induction drive

The HARRIER range utilises an induction motor for maintenance free long life operation. This motor has no carbon brushes so not only is there no need for routine maintenance but there is no build-up of carbon dust inside the centrifuge. This makes it suitable for use in clean environments. Microprocessor control combined with the frequency driven motor ensures accurate operation for run to run reproducibility.

Refrigerated version available

The HARRIER 18/80 REFRIGERATED combines all the capabilities of the proven HARRIER 15/80 in a refrigerated format. The selectable temperature range is from −90C to +40C and uses CFC–free R134a refrigerant gas. This means that in refrigerant terms, the HARRIER 18/80 REFRIGERATED complies with all the regulations pertaining to the Montreal Protocol. A pre-cool facility allows the bowl to be cooled to the required temperature prior to use.

High speed microtube rotor

The use of the induction motor provides another benefit in that higher rotational speeds can be achieved. This allows the HARRIER range to have a maximum speed in excess of 15,000 rpm with the 24 place microtube rotor. The addition of refrigeration in the HARRIER 18/80 REFRIGERATED unit allows the microtube rotor an increase in speed to 18,000 rpm giving a maximum ‘g’ force of 28,980 ‘g. See rotor table for details.

Wide range of accessories available

For routine bench top work, the 4 x 200ml swing out rotor and 200ml sealed buckets are available on the HARRIER 15/80. A recent addition on the HARRIER 18/80R is the 4 x 200ml wind-shielded rotor. This uses the same 200ml buckets as used on the HARRIER 15/80 but with an increased speed capability of 6,000 rpm giving a maximum g force of 6,466 g. These, combined with a wide range of adaptors, can accommodate most manufacturers’ tubes. As well as the swing out rotor, other angle rotors and specialist rotors are available.
