Rotaphor V6 Pulsed Field Gel Electrophoresis

Latest Version from 08.09.2010

Deutsche Version dieser Seite .

This page contains everything you need to try or update the software for controlling the pulsed field electrophoresis apparatus "Rotaphor".

The software might be used without the chamber, since an additional window allows the manual simulation of the signals coming usually from the apparatus.


  1. The Rotaphor Installer needs some funktions of the DotNet library 1.1. If this library is not jet available on your computer (the Rotaphor Installer checks for availability and requests installation if necessary), please download theDotNet library and install it. Please mind that administrator rights are necessary for this task and the license needs to be accepted. The installation process take sometimes very long especially when "0 minutes left" are shown. Please be patient and wait for a window reporting the end of the installation. If the DotNet library is already available on your coputer, skip this step.

  2. In order to install the Rotaphor-Program, please download Rotaphor V6.07.04 (~2 MB). This Windows Installer leads you through the installation. If you want to provide access for all users, choose "Everyone" during the installation process. For easy later updates we recommend accepting the installation path offerd by the program. Administrator rights are essential for this procedure.

  3. If you want to update only a previous version of the Rotaphor program, please use this selfextracting Updater. It is functional only with an english version of windows. The german version might be found here. With recent windows versions, the Updater needs to be started as Administrator to allow the replacement of old files.

If you have any requests, suggestions or pictures of nice separations, please send an email.

We hope you enjoy this software

Your Rotaphor Team

07.07.06 V6.4.02 Program may now be ended during user selection and user definition.
12.07.06 V6.4.03 Running a second instance of the Rotaphor program is now prevented to avoid hardware blockage
16.07.06 V6.4.04 Very fast restart after an error message sometimes blocked all further inputs. Eliminated.
31.07.06 V6.5.01 Application of a second dimension did position the rotor sometimes wrong. Eliminated
Interval und angle parameters are now hidden during a standard electrophoresis.
Input of physically impossible values during temperature calibration reactivates default values.
27.08.06 V6.5.2 Minor improvements in user interface, tests without power supply enabled.

12.06.07 V6.5.4

Interrupt times modified to have same rotor velocity for alls computers.

V6.5.5 Problem resulting from update (V6.5.3) with power failure eliminated, handbook updated
V6.6.1 Menue rotor velocity renamed to options and new choices added: High tolerance for problems with positioning and reduction of irrelevant messages
6.06.03 Kalkulation of glitches regarding the ligt barrier improved
6.06.04 Lightbarrier glitch korrection limited to a physically useful value, because nonsense values after power failures prevented continuation of the elektrophoresis.

09.10.2010 6.07.04a Device driver of chip manufacturer prevents Rotaphor program from reconnecting to chamber if restarted. Replaced with working version. Rotaphor program unchanged
