Filling of density gradient tubes
Density gradient centrifugation is frequently used to separate different cell types or cell organelles, ribosomes or DNA from crude cellular extracts. The CUSTOMIZE mode permits gentle and fast building of density step gradients. To avoid stirring up the different layers, dispensing starts gently at a low flow rate and then ramps up to the target speed. This allows filling density gradient tubes gentle and faster than if carried out manually.

Serial dilutions
Serial dilutions are extensively used for example in microbiological testing as part of the sample preparation for the total viable cell count in food. By programming an air gap before taking up the sample into the prefilled tubing system, the CUSTOMIZE mode allows you to efficiently carry out serial dilutions.
