Flow Splitter with adjustable split ratio

Flow-Splitter adjustable ASI

    Wide range of split ratios

The split ratio of the very simply constructed splitter 
    is determined via two fluid resistors.

The Flow Splitters can be used for all applications requiring a precise and constant split. The split ratio is precisely adjustable and reproducible. Because of the very low dead volume, the solvent composition is the same in both resistor cartridges at any given time, so that viscosity changes associated with gradient runs do not affect the split ratio. 

The handling is extremely simple, the split ratio is precisely defined and reproducible. These Flow Splitter are
available for analytical, semi-preparative and preparative HPLC.

Nano-Flow Splitter for split flow rates as low as one nanoliter per minute!
Dead volume on the low flow side is as low as 5 nanoliters! Range of adjustment = factor 20!

Performance characteristics

  • Universally suitable for all splitting applications, e.g. between two detectors, for fraction collection or for pre-column splitting of the solvent stream

  • Flow splitters with adjustable split ratios for pre- or post-column applications

  • Extremely low dead volume (100 nl), so that viscosity does not influence the split ratio

  • Analytical, semi-preparative and preparative versions available

Adjustable flowsplitter are recommended especially when working with different detectors, which require different input flows.
