Ideal for tissue culture applications the Zeiss Axiovert 25 is a solid choice for everyday use. We have two options - with or without a mechanical stage. If you choose with a mechanical stage the microscope will have a 0.4 N.A. condenser an a photo port. If you choose without a mechanical stage the microscope will have a 0.2 N.A. condenser and will not have a photo port. Both options will include a pair of 10x/18mm FOV eyepieces. The four position nosepiece has CP Ahromat 5x, CP Achromat 10x Phase, and Achrostigmat 20x Phase objectives. This used microscope comes fully serviced with a warranty.
