Postnova model 8050 FFF fraction collector

The Postnova 8050 FFF Fraction Collector employs the latest state-of-the-art robotic sample and fluid transfer technology such as a double needle, special wash routines for minimal carry over and direct fractionation into closed vials. It can be operated with different microwell plates, Eppendorf caps as well as chromatography and preparative vials. It is available as biocompatible and metal-free version and thus is the ideal fraction collector for use in Field-Flow Fractionation and off-line coupling to spectroscopy detection such as AAS, ICP-OES and ICP-MS.

Offering space for two stainless steel racks or two well-plates, model 8050 is ideally suited to be integrated with a wide range of different Postnova Field-Flow Fractionation systems and for various applications with small, normal or large volume fractions. The precise and reliably designed Peltier cooling/heating keeps sample fractions stable in a closed environment which is hermetically sealed for maximum reproducibility and minimal artefact generation. The temperature range from 5°C up to 40°C prevents sample degradation, solvent evaporation or precipitation and aggregation of collected fractions.

Model 8050 fraction collector allows the flexible use of 96-well or 384-well plates, deep or shallow, sealed or open. Standard chromatography vials 1.5 mL sealed or open and with or without micro-insert can be used. The system can also handle special vial formats such as small Eppendorf tubes and preparative vials with 10 mL volume. For absolute metal-free operation Postnova offers special PFA and pure quartz glass vials which can
be closed with caps and septa.

Model 8050 fraction collector is controlled by the Postnova NovaFFF software.
