The Ultima In Vitro Multiphoton Microscope System is the platform on which leading scientists have conducted breakthrough experiments in brain-slice studies related to neural signaling and neural network mapping. Ultima In Vitro provides simultaneous imaging and electrophysiology, plus uncaging and photostimulation for the complete stimulus and recording environment required for research by today’s neuroscientist.
Ultima In Vitro is the ultimate “slice rig," having provided the platform on which leading scientists have conducted breakthrough experiments in brain slices related to neural signaling and neural networks for more than ten years. The system provides the flexibility for the most demanding protocols, and is available on upright or inverted optical microscopes. Features include:
The Atlas Imaging module in Prairie View software simplifies setup of 2D and 3D automated montages. X,Y boundaries are easily setup through a thumbnail display. Tiles not containing areas of interest can be turned off, and the Z range for 3D montages can be variable, allowing more efficient collection of data.
Tissue explants provide a higher throughput model for studying tissue response to pharmaceutical agents. The FLIM option allows measurement of metabolic status through measurement of fluorescent lifetimes.
Ultima In Vitro is the system of choice for studying neuronal signaling at the both the dendritic and neural network levels. When equipped with optional photostimulation galvanometers, Ultima In Vitro provides a complete optical workstation, allowing simultaneous imaging, photostimulation and electrophysiology recording.
Ultima In Vitro provides high resolution and efficient volumetric imaging of cell cultures and cells in artificial matrices.

We appreciate the modular nature of the Ultima hardware and software. The systems now available range from basic imaging systems to the dual-laser photo-stimulation multi-mode imaging workstation. We have continued updating many of our 14 machines, including our ten year old systems. The Team Viewer connection and support is a huge asset for novice owners and for significant software changes.
