Hamilton Thorne  IVOS II  Sperm Analyser


Computer Assisted Sperm Analyser

The IVOS II hardware platform sets forth the development of the IVOS CASA system:

Smoother, faster integrated stage featuring acceleration and deceleration.

The IVOS II is an Integrated Visual Optical System for sperm analysis.

Since its development, the name IVOS has been synonymous with fast, accurate, reliable and scientifically tested sperm analysis.


Integrated Optics

As the only sperm analysis system with an internal optical system, the IVOS II offers distinct advantages to the sperm analysis laboratory. In contrast to the continuous illumination of a microscope, the IVOS uses illumination strobed at 1/1000 of a second to visualize sperm motion. This strobed illumination eliminates motion-related blurring along the length of the sperm head, resulting in precise sperm tracking. By adding an image capture rate of 60 frames per second, you get the highest level of accuracy available today for measuring sperm velocities and motion parameters. For added flexibility, the IVOS performs analyses under three types of internal, strobed illumination: phase contrast, bright field and multiwavelength fluorescence.

Automated, Internal, Heated Specimen Stage

As part of the integrated optical system, the unique computer controlled specimen stage of the IVOS II provides precise control of temperature and position during analysis.
The stage temperature, which may be set from ambient to 40°C, remains constant to within 0.5 °C.

For selection of analysis Multispecies Sperm Analysis Compatibilityfields, the stage may be programmed for either manual or automatic field selection. For at-a-glance monitoring, the current stage temperature and position are continuously shown on screen as a real-time, digital display. The IVOS stage accommodates and automatically adjusts for commonly used analysis chambers, such as disposable fixed-depth slides, cannulas and Makler chambers. In addition, a user-defined chamber setting is available Depending on your need, the IVOS comes with standard Clinical (human) software, TOX IVOS software, Swine UltiMate software, Equine Breeders, Animal Breeders and Animal Motility Software.

Ease of Use

The IVOS II hardware and software have been designed to provide users with a system that offers high-end performance while maintaining its ease of use. The intuitive Windows-based software promotes fast learning and quickly increases the confidence level of users. Since the settings for the integrated optics are made through the software, mechanical adjustments are rarely required. With a minimum investment of time, even users unfamiliar with computers will be performing fast, accurate and reliable sperm analyses. You don’t need to be a computer expert to analyze sperm with the IVOS.

Results You Need

Whether you need basic counts and motilities or detailed analysis of sperm motion, the IVOS II provides you with the results you need. Results for motile, progressively motile and static sperm include actual number counted, sample total, concentrations and percentages. Additional results include averages and distribution bar charts of velocities, motion characteristic and morphometry.

Real-Time Quality Control

The IVOS II provides on demand quality control with the Playback feature. Using image Playback, the accuracy of the analysis is confirmed. To optimize the system, analysis parameters may be adjusted using the two interactive QC Plots or directly from the analysis setup screen.

Rated Moderately Complex by CLIA

Because of its ease of use and high levels of quality control, the IVOS has been awarded a rating of moderately complex by CLIA. This means fewer restrictions for you lab!
