After fertilization of the oocyte you monitor the embryo growth until the implantation of the embryo. Embryologists have developed morphological parameters that indicate a good or bad prognosis for the developing embryo. Each developmental step is carefully observed. Indicators for a "high quality" embryo are:
- Cell number - blastomeres and day 3 embryo
- Cell regularity
- Fragmentation / blebbing
- Presence of vacuoles, granularity, thickness of the outer shell (or zona pellucida)
ZEISS Stemi 508
Stemi 508 is your compact stereomicroscope, that fits in any standard Laminar Flow Box. The large working distance offers ample space: you can conveniently control the development of the embryos. The operation of the microscope is easy and intuitive. Due to the optional Thermo plates you can keep your samples at 37 °C while they are outside the incubator.
ZEISS Axio Vert.A1
Axio Vert.A1 is perfectly suited as basis for your standard ICSI system. This compact inverted microscope is particularly impressive in terms of its price-performance ratio. Choose your preferred micromanipulation system since the system is compatible with all common models. Even laser-assisted hatching or embryo biopsies for PGD/PGS can be performed, e.g. with Hamilton Thorne's laser system. Use all relevant contrasting techniques: with Axio Vert.A1 you have access to PlasDIC, iHMC, phase contrast and DIC - ideal for routine IVF/ICSI and even IMSI. Plus, Axio Vert.A1 fits completely inside your laminar flow box.
ZEISS SteREO Discovery.V8
SteREO Discovery.V8 is equipped with open interfaces, that allows for integration inside your laminar flow box. Its modular design and extensive accessories offer you a variety of options to set up your workplace to your exact requirements. The impressive stereoscopic image helps you to better observe the development of the embryos. You get a high-resolution, high-contrast, and apochromatically corrected microscopic image – that is your key for taking the right decisions. With its 8× zoom, you can quickly change from the overview down to the magnified detail, while staying perfectly in focus. SteREO Discovery.V8 combines robustness, ergonomy and brilliant optics, providing optimal reliability in your workflow.
ZEISS Axio Observer
For successful ICSI (Intracytoplasmic Sperm Injection), clearly visible structures such as the zona pellucida and polar body of the egg cell are essential. With IMSI (Intracytoplasmic Morphologically Selected Sperm Injection), you can also assess the shape and vacuole count of the sperm cells. In borderline cases, several contrast techniques have to be possible that can deliver scientifically unambiguous, high-contrast images. Axio Observer provides all relevant contrasting techniques in one single stand. HMC, PlasDIC and DIC are all possible. Additionally, you can combine phase contrast with all methods. Axio Observer is readily compatible with all major laser systems to perform laser-assisted hatching or embryo biopsies for preimplantation genetic testing (PGT). This future proof microscope leaves nothing to be desired.
