Patent ID: 7642785

Claim:
For use in a system that includes an electronic analyzer for determining a property of a sample material, an apparatus comprising: a cylindrical chamber for receiving the sample material; a first coaxial connector having a first relatively small diameter end coupleable with said electronic analyzer and a second relatively large diameter end communicating with a side of said cylindrical chamber, said first coaxial connector having inner and outer coaxial conductors; said inner coaxial conductor of the first coaxial connector having a diameter that tapers outwardly from said first end to said second end, and said outer coaxial conductor of the first coaxial connector having an inner surface whose diameter tapers outwardly from said first end to said second end; a second coaxial connector having a first relatively small diameter end coupleable with said electronic analyzer and a second relatively large diameter end communicating with the other side of said cylindrical chamber, said second coaxial connector having inner and outer coaxial conductors; said inner coaxial conductor of said second coaxial connector having a diameter that tapers outwardly from said first end to said second end, and said outer coaxial conductor of said second coaxial connector having an inner surface whose diameter tapers outwardly from said first end to said second end; wherein said cylindrical chamber is within a tubular cylindrical body, and wherein the second ends of said first coaxial connector and said second coaxial connector are inserted in opposing ends of said cylindrical body, thereby defining said cylindrical chamber between said second ends and the internal wall of said tubular cylindrical body.
