Caton Macroinvertebrate Subsampler

If you’re looking for a macroinvertebrate subsampler, I’m your man.  In the late 80′s I got frustrated trying to randomly "pick bugs" from a white pan full of debris.  I tried a variety of homemade gadgets to overcome the problem, and eventually came up with my subsampler.  You can find the published article in the 1991 Fall Bulletin of the North American Benthological Society.

I started making subsamplers for my aquatic biologist friends at cost, but eventually people wanted so many I was spending all my time in the garage.  So for the last 17yrs I’ve run a hobby size business selling subsamplers to biologists across the USA and in a few other contries too.

If you need a Caton Subsampler, send me an email at larrycaton@msn.com, or phone or FAX an order to 503-246-0891.  It usually takes 3 to 4 weeks to fill an order and the cost is $325 for a kit plus shipping and handling.  If you want to make a subsampler yourself, I can share ideas and send basic instructions.

Cheers!
