I am currently using a Tissue Tearor to homogenize soil samples to analyze extracellular enzyme activity. This device was not designed for such an abrasive material and I am finding that the bit is getting worn down quite quickly (these things are not cheap!). Does anyone know of a more appropriate device/method to use? Any advice would be appreciated

Thanks, Jen

It is pretty common to use a Waring blender to homogenize soil samples. Many people use the lab version available through Fischer, VWR or others. They also make smaller volume stainless steel containers. Have a look a the protocols on this website for more info.

I've been using a standard kitchen immersion blender from Target. It works quite well, but I would suggest getting two if you are doing alot of samples to prevent overheating. They typically run about $40 a piece.
