The BioQuantum™ K3™ imaging filter provides fundamental insights into cellular organization and ultrastructure by combining high-performance post-column energy filtration with direct detection technology. Ideally suited for low-dose imaging applications, helps researchers to maximize their cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET) capabilities to gain further insight into system function and disease progression at the molecular level.

  • Higher DQE: See smaller particles, more confidently detect conformational changes, perform cryo-ET at lower dose, preserve higher resolution information for 3D reconstruction
  • Optional inline, GPU-based motion correction: Avoid the need to save terabytes of raw frames
  • 24 megapixels (5,760 x 4,092) field of view: 1.6 times the size of the K2® camera
  • 1,500 full frames per second: 3.75 times the speed of the K2 camera
