A laboratory evaluation of Compur M 1000 Miniphotometer and the Compur M 11OO minicentrifuge

The Compur Miniphotometer and Minicentrifuge are portable instruments designed for rapid estimation of haemoglobin, red cell count and haematocrit on capillary blood. Haemoglobin and haematocrit results correlate well with reference methods. Accurate red cell counts are only obtained when the sample MCV is within the range 83--103 fl, thus restricting the application of this method. The Compur M 1000 Miniphotometer and Compur M 1100 Minicentrifuge have been designed as portable instruments to permit rapid estimations of haemoglobin concentration, red cell count and haematocrit by the non-laboratory worker.
