A tissue chopper is a cutting/slicing instrument used to cut fresh living tissue in cube slices and arterial rings without the need for freezing g or embedding.
The tissue chopper is an electrically powered appliance, and therefore the blade or cutting speed and slice thickness can be determined prior to operating the chopper. Adjustments to the blade speed, which is around 0-200 strokes per minute, are made by rotating a speed knob. The slice thickness can be calibrated on a micrometer head (1 micron – 25 micron).
Visual Patching Imaging Chamber
Visual patching and imaging chamber is a temperature control device employed to maintain the specimen temperature, thereby preserving it in optimal conditions for a longer duration during imaging or electrophysiological experiments.
A visual patching imaging chamber is a device used in neuroscience research to study the activity of neurons in the brain. It typically consists of a chamber that is used to hold an animal, such as a mouse or a fly, in place while a microscope is used to image the brain. The chamber is designed to allow researchers to selectively “patch” or stimulate specific areas of the brain while also being able to observe the neural activity in that region. This technique is known as “in vivo patch-clamp” and it is used to understand the function of individual neurons and neural circuits.
