RapidTrace – automated SPE

The automatic solid phase extraction (SPE) instrument manufactured by the Swedish Biotage company eliminates all the reproducibility problems, the ones doing SPE sample enrichment often face during the procedures carried out with vacuum. The RapidTrace+ applies positive pressure and accurately adjustable flow during the successive sample loading, washing and eluting steps. The samples in the test tubes can be placed in the 10-position sample holder of the instrument, and the standard size 1, 3 or 6 ml SPE cartridges may be placed in a rotating carousel.

For fraction collection also a place for 10 test tubes is available. From one sample more fractions can be collected, however, in such cases the initial sample size must be reduced. For the placement of the reagents and the solvents 8 separate lines, and for the collection of the waste 4 separate lines can be used. For a large number of samples 10 RapidTrace+ can be bound into a system, providing high throughput capacity. The setting of the operating parameters is provided by an easy-to-handle software which makes possible the use of the different methods with each sample.
