Fraction Collection using Valves
Knauer rotary valves offer a low-cost flexible solution for fraction collection in preparative chromatography. Valves with six, twelve or sixteen ports are available in either stainless steel or peek versions. Positioning is controlled via a standard electric valve drive module which can be controlled either manually or using remote control.
Fraction Collection Software
Use of the Knauer Fraction Collection software option fully automates the application and allows also solvent or peak recycling if required.
Inert Collection Possibilities
Using these valves it is possible to design systems where the process occurs with complete isolation of the sample or product. Fractions are collected directly into standard laboratory bottles which can be fitted with quick-connect adapters to allow rapid and safe exchange of bottles as required.

Fraction Collector Foxy® R1
The Foxy® R1 is the improved successor of the well-known Foxy® Jr. and can be used for a variety of applications.
The Foxy® R1 accomodates the same rack types as its predecessor, but provides faster operation, more control options (RS-232 and Ethernet) and features an integrated diverter valve as a standard.
When connected to a detector, the Foxy® R1 offers slope detection, level sensing, and a combination of these methods.
The applicable rack types range from 96-well microplates, to test tube racks, to funnel racks for virtually unlimited collection volumes. The Foxy® R1 is biocompatible and can be used in cold room environments.
Foxy® R1 can be fully controlled as a stand-alone unit or by using Knauer software together with the Fraction Collector Control Option.
Key features
Fraction Collector Foxy® R2
The Foxy® R2 fraction collector is ideal for applications including prep HPLC, protein and peptide purifications and is available in three different versions with different tubing connections.
The Foxy® R2 doubles the collection capacity, and uses Radio Frequency Identification (RFID) for error-free rack configuration and provides faster operation, more control options (RS-232 and Ethernet) and features an integrated diverter valve as standard, when connected to a detector, the Foxy® R2 offers slope detection, level sensing, and a combination of these methods.
The applicable rack types range from 96-well microplates, to test tube racks, to funnel racks for virtually unlimited collection volumes. The Foxy® R2 is biocompatible and can be used in cold room environments.
Foxy® R2 can be fully controlled as a stand-alone unit or by using Knauer software together with the Fraction Collector Control Option.
Key features
Fraction Collector LABOCOL Vario-4000
The LABOCOL Vario-4000 fraction collectors are characterized by their high robustness and optimal ratio of dimensions/benefit. The user is not limited to given rack types. The rack layout can be designed according to individual needs and the number of fraction vessels and their position can be freely defined. The wide application area make the Vario-4000 series ideal for use in research and development as well as in production. The Vario-4000 models differ in the base area and the flow rate range.
A large range of standard test tube rack is available. Funnel racks for virtually unlimited collection volumes are also available as standard modules. The Vario-4000 is bio-compatible with the only contact materials being PTFE and PEEK.
The Labocol-4000 can be fully controlled as a stand-alone unit or by using Knauer software together with the Fraction Collector Control Option.
