Methods of fixing and processing tissue and samples on a membrane by using ultrasound radiation as a part of the method are presented. Ultrasound of a frequency in the range of 0.1-50 MHz is used and the sample or tissue receives 0.1-200 W/cm2 of ultrasound intensity. The use of ultrasound allows much shorter times in the methods. Also presented are apparati comprising transducers of one or of multiple heads for producing the ultrasound radiation and further comprising a central processing unit and optionally comprising one or more sensors.

Why it's free to use
- Filed July 6, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 6, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
