Upgrade kit for existing instruments

the upgrade kit enables new applications and significantly increases throughput and resolution of the FFE system. All instruments sold from 2004 can be upgraded to the current technology.

The basic upgrade contains:

  • Modification of the top and cooling plate:
    new wall material to enable up to four days of continuous operation
    new spacer for a gap size of 0.15 mm for highest resolution separations
    increased fieldstrength of up to 800V/cm for high throughput separations
  • Modification of the electrode buffer circuit:
    new pump system for improved and silent operation
  • Installation and training at customer site and access to the latest protocols
    after sales training courses

FFE robotic system
