The Dino Lite MS33W Desktop Stand is very similar to our extremely popular MS32W flexible stand in that it gives the user a 360° range of movement as well as the freedom to move the microscope vertically and position it in awkward spaces. The metal flexible arm can be bent into the position of your choosing and holds your Dino Lite steady, freeing up your hands for other tasks.The connection between the base and flexible arm features an adjustment dial that raises or lowers the whole arm about 10 millimeters in either direction, allowing for micro adjustments in focus or positioning.The flat, solid metal base can be clamped to the edge of a table (clamp not included) for added stability while the rubber feet attached to the bottom of the base protects the surface of the table and adds further vibration resistance. The flexible arm is 13 inches long and the base diameter is 4 inches.
