The Z4 Zoom Stereoscope with the Embryo-GLO Base is tailored for embryo transfer specialists. With magnification ranging from 7x to 45x, it provides high-resolution 3-D viewing of embryos, while 10x eyepieces with a reticle aid in size assessment. Upgrading to 15x eyepieces offers increased magnification, though 45x is often preferred.

Unlike traditional stereoscope bases, the Embryo-GLO Base features a rear-mounted LED bulb, eliminating glare and providing clear embryo visibility. Its adjustable tilting mirror enables indirect lighting at various angles, enhancing observation of internal embryo structures. The dual-sided mirror offers both focused and diffused illumination, while the variable intensity LED system ensures optimal brightness for different magnifications. Utilizing the Z4 Zoom Stereoscope on Embryo-GLO Base facilitates morphological evaluation, ultimately enhancing fertility rates in embryo transfer programs
