ABSTRACT:
A nanoliter rheometer is capable of operating over a wide range of temperatures and permits visual observation of extremely small amounts of various often complex and/or expensive small nanoliter size fluids over a wide viscoelastic regime. The nanoliter rheometer comprises two very thin fibers, the ends of which are in close proximity to one another and desirably parallel to one another with one fiber being moved by a drive system and the remaining fiber desirably being stationary and capable of measuring a force transferred through a nanoliter size fluid located between the two fibers ends. The transferred force can be measured either by an LCR meter or a piezoelectric crystal and recorded as by a lock-in amplifier.
