Centrifuges


Laboratory Centrifuges

Laboratory centrifuges work by the sedimentation principle where centrifugal acceleration is used to separate substances by their relative density.

Microcentrifuges
Micro Centrifuges are used to spin small tubes or micro tubes (0.2 ml to 2.0 ml) usually made of plastic.

Hematocrit Centrifuges

A Micro haematocrit centrifuge is a specialised centrifuge for determining the packed cell volume (PCV) of a blood sample, also known as a hematocrit.
Micro Hematocrit centrifuges are designed to spin microhematocrit capillary tubes. The tubes are 2/3 filled with whole blood by capillary action, sealed with clay at the unfilled end of the tube and placed in the radial grooves of the centrifuge rotor.

Multi Purpose Benchtop Centrifuges

Multipurpose centrifuges typically cater for a broad range of tube sizes and can be used to separate a number of different liquid and sample types, including, blood, urine, semen etc.
Combination Centrifuges. A combination can be fitted with different rotor types depending on the type of sample to be centrifuged.

All of these centrifuge types can be purchased from GrayMed Australia at Centrifuges.
