Model: MK-12    Cat.No.: MK-12
Manufacturer: Muromachi Kikai Co., Ltd.

Electronic Vaginal-Estrous Cycle-Monitor, Rat.
MK-12 Rat Vaginal Impedance Checker has been designed to obtain a precise information on optimum day for mating during estrous cycle in the rats.
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.
The conventional method known as vaginal smear method takes troublesome procedures such as taking smear, drying, dying and check-up using microscope. It really takes skill as well as time and labor.
Rat Vaginal Impedance Checker is a time & labor saving device on top of high reliability. Further, operation is so simple that even inexperienced personnel can easily use it.
p/n RP-45A - Probe for Rat (55mmL x 4.5mmOD).
p/n MP-35 (50mmL x 3.5mmOD) - Probe for Mouse*.
*(Important Note: The MK-12 has been developed exclusively for rats. Mouse probe is available upon request, however, the manufacturer will not assure whether a satisfactory test result can be obtained.)
