Automated, Gentle Media Exchange

Spheroidal 3D cell culture is increasingly common for many research areas as it better mimics the in vivo environment. It can be challenging to perform media exchanges and washes without accidental cell structure loss.

BioTek’s patent-pending Automated Media Exchange AMX module for the MultiFlo™ FX enables gentle automated media exchange to protect and encourage proliferation of spheroids, tumoroids and other 3D cell structures, 2D and suspension cells in microplate-based assays. The AMX module uses both peristaltic pumps, one to dispense and one to aspirate media from the plate wells.

The software operates the pumps slowly and gently so cells and cell structures aren’t disturbed during the media exchange, and the x-y-z positions for the aspirate and dispense tubes are adjustable to avoid contact, etc with cell structures in the wells.

AMX Benefits:

  • Automates media exchange and washing for spheroids, tumoroids and other 3D cell structures, 2D and other cell structures
  • Helps protect cells and encourage cell structure growth
  • AMX module can be added to MultiFlo FX and easily exchanged with other modules for workflow versatility
