Sigma 1-7 Compact Centrifuge

Buy Now

The NEW Sigma 1-7 small, compact centrifuge is ideally suited to the separation of blood and urine samples in the clinical sector. The compact size with single fixed angle rotor is perfect for the separation of small and medium sized sample tubes. The centrifuge also has reasonably high RCF capability and is finished in a sturdy, high quality finish. The Sigma 1-7 generates exceptionally low vibrations and is pleasantly quiet.

This compact centrifuge is ideally suited to GP practice, surgeries and veterinary laboratories for the processing of blood samples in vacutainers and monovettes. The purpose-made fixed angle rotor will hold most types of conventional blood tubes for in-vitro diagnostic (IVD). The high RCF of 6153g assists greatly in speeding up separation times. The short acceleration and braking times of 13 and 11 seconds, respectively, make results available in next to no time.
