Common to all innovative, fully automatic staining devices from Dagatron is the injection method. The injection method reliably prevents sample carry-over and cross-contamination due to the horizontal, individually stored arrangement of the preparations in the device.
The consistent, uniform staining result for the complete preparation is achieved by evenly applying the staining solution in the required reagent quantity through the injection heads by means of microprocessor control. In contrast to staining based on the spray method, standardized, repeatable results can be achieved without loss of sample material due to insufficient wetting with the staining solution.
By using a separate injector head for each reagent, the contamination of different reagents can also be excluded.
