Are you still looking for an instrument or lab? Try www.ipt-online.com. I believe that the only reliable data from a Jenike tester are data obtained from Jenike. The instrument is operator sensitive, so unless you've been trained by Jenike and Johanson, I'd either ship my samples to J&J or look for an automated tester.

Give Dr. Peschl a call. His website is www.ipt-online.com. Don't forget to include the hyphen when you type the address. Otherwise, you'll get Reg Freeman's website. I believe Freeman has a hundred WWW addresses that point to his location. In any event, IPT will run all the tests for you for about 1500 euros per sample, or you can lease a machine and take measurements yourself. The Peschl cell is fully automated. It takes about 5 minutes of sample preparation, and then the instrument runs automatically. By the time you've finished your coffee, the unconfined yield strength, consolidation stresses, and angles of internal friction will be displayed on the computer monitor.

I think Dr. Peschl is from Croatia so he might give you a break... ■
