KingFisher Flex 96

The KingFisher Flex 96 performs magnetic bead-based purification of DNA, RNA and protein. Magnetic rods covered by a disposable tip comb move the beads between plates, rather than liquid moving between vessels — so there is no pipetting and nothing to carry over.

At a glance

Type	Magnetic bead-based purification processor
Samples per run	Up to 96
Revolution control	Run a full protocol; position the carrier by name or number

Specifications

Thermo Fisher publishes the following.

Consumable	96-well plates, with magnetic rods covered by a disposable tip comb
Heads	24-magnet head for volumes up to 5 mL; 96-magnet head for full 96-sample throughput
Run time	A 96-well plate in under 2 hours
Heating	+5 °C above ambient to +115 °C
Depth	23.6 in
Height	15 in

The head fitted decides the volume, not just the sample count: the 24-magnet head takes you to 5 mL, while the 96-magnet head gives full throughput. That is a hardware choice made before a method is written.

Note the heating range starts at +5 °C above ambient — like several instruments in this catalogue, it heats but cannot cool below room temperature.

Supported methods

• Run protocol — run a purification protocol end to end, from a protocol file. A run report (Report.kfrun) is written to a report folder you supply.
• Move to position number — move the carrier to a numbered position (1–8)
• Move to position name — move the carrier to a named position

Positioning by name or number is both supported. Names survive a protocol being re-ordered; numbers do not. Prefer names where your protocols define them.

Integration

Prerequisites

• The instrument must be reachable from the Revolution host.
• The purification protocol the schedule runs must already be defined in Thermo Fisher’s software.
• The magnet head fitted must suit the sample volume the protocol expects.
• Tip combs and plates must be loaded for the protocol — a bead-based run with no tip comb moves nothing.
• Positions referenced by name or number must exist on the instrument.
• Locations picked from or placed to the instrument must be named with a trailing digit giving the position number, e.g. KingFisher1_1, KingFisher1_2.

Device configuration

Property	Purpose
Url	Address of the controller service the Revolution host connects to
Instrument Name	Identifies which physical instrument to connect to
Config File	Vendor client configuration file used to reach the instrument
