IX73 ICSI/IMSI Inverted Microscope System

Reference: EVI-IX73 ICSI/IMS

https://www.analis.com/web/image/product.template/136049/image_1920?unique=689d05d
The IX73 Inverted Microscope System from Evident is expertly designed for ICSI, IMSI, and spindle observation in assisted reproductive technologies. With a semi-motorized configuration, this advanced solution supports consistent, high-resolution visualization, minimizing user fatigue while maximizing workflow efficiency.

High-Precision Imaging for Advanced Reproductive Research

Ideal for IVF labs, the IX73 system ensures seamless switching between imaging methods, helping embryologists focus on critical micromanipulation tasks with speed and confidence.

Why Choose the IX73 for ICSI/IMSI?

  • Designed for IVF: Optimized for ICSI, IMSI, and SL-ICSI techniques.
  • Improved Workflow: Motorized switching between objectives and condenser positions with one-button operation.
  • High-Contrast Imaging: Supports relief-contrast and differential interference for clear oocyte and sperm visualization—even in plastic dishes.
  • Effortless Operation: Focus and brightness automatically adjust with magnification changes.
  • Expandable Configuration: Compatible with third-party micromanipulators and accessories.

Application Highlights

  • ICSI (Intracytoplasmic Sperm Injection)

Relief-contrast observation enables clear visualization of 3D oocytes in plastic dishes—ideal for assessing the zona pellucida and injection conditions.

  • IMSI (Intracytoplasmic Morphologically Selected Sperm Injection)

Differential interference contrast (DIC) supports high-magnification inspection of sperm head morphology and vacuoles—available with optional IMSI unit.

  • SL-ICSI (Spindle Localization)

Olympus' polarizing optics reveal the metaphase II spindle, helping avoid spindle damage during microinjection procedures.

Key Features

  • Semi-motorized microscope with motorized switching of condenser/objectives
  • Spindle observation standard (polarized light)
  • One-button switching between observation methods via hand switch
  • Supports IMSI with optional unit
  • UIS2 optical system for superior image quality
  • Compatible with relief contrast, DIC, and polarization techniques

Looking for full automation? 

The IX83 model offers a fully motorized alternative to the IX73, ideal for high-throughput IVF labs seeking maximum precision and workflow automation.
