Electronic Monitor for Vaginal Estrous-Cycle for Mice and Rats

Reliable, time-saving, optimizes animal comfort

• The best method to determine the proestrus stage in rats, the first stage in the estrous cycle.
• A reliable time and labor-saving device. Operation is very simple, even for a novice. In comparison, the conventional vaginal smear method is traumatic to the animal and a troublesome procedure requiring skill, time and labor.
• The electrical impedance of the epithelial cell layer of vaginal mucosa is measured at the frequency of 1 kHz by insertion of the probe into vagina. In the proestrus stage significantly high impedance is produced compared to that in the other stages of the estrous cycle. 3 kohm of impedance can be considered a standard indicating proestrus stage. Measuring range is 0 – 19.9kohm.
• A mouse probe is available, but test results are not guaranteed.
• The device is automatically calibrated when turning on the power.
