Maxi is primarily designed for resolution of high numbers of samples as in cloning or PCR experiments. Maxi allows ultra high-resolution separations over extended runs. Tray sizes correspond to standard blotter sizes. It also allows for easy sample transfer onto a membrane for further analysis. Three tray sizes are available, 20 x 20cm, 20 x 25cm and 20 x 10cm. Multi-channel pipette compatible combs for up to 40 samples each facilitate speed loading of up to 440 samples per gel. 50 sample combs (not multi-channel pipette compatible) allow maximum sample capability of 550 samples per gel.
