Overview
Fraction Collection using Valves
Overview
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 solventor 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.
Standard Fraction Collectors
Smartline Fraction Collector 3050
The ultra fast drive enables position changes in very short times, allowing collection of
very narrow peaks, for instance in UHPLC.
The Smartline Fraction Collector 3050 is available in two versions: an analytical version for flow rates up to 5 ml/min with cover and optional sample cooling or a semi-präparative version for flow rates up to 50 ml/min. The fraction collector can collect up to 384 fractions in well plates or up to 192 fractions in
standard autosampler vials.
Due to the identical rack design the racks can be transferred directly to autosamplers such as the Smartline Autosampler 3950. Special racks for different test tubes, beakers or flasks up to 250 ml also can be used.
The fraction collector can be controlled with ChromGate® software, with or without the FRC option, or ClarityChrom® Prep via LAN or RS232.
Sensitive samples can be protected against warming using the cooling option.
A solvent and peak recycling option with two additional valves is available for saving solvents and
costs.
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 using either the ChromGate® software together with the Fraction Collector Control Option or with our Geminyx Software.
