Auxiliary Component Setup and Operation
10.1
Auxiliary Scales
The TFF systems interface with digital Ultra Precision Surface Acoustic Wave (SAW) auxiliary scales.
These SAW scales are sensitive, accurate, stable, and versatile—which makes it a dynamic
instrument suitable for the varied application environments of TFF processes. For detailed
information on running SAW scales, refer to the manufacturer's information that came with the
scale. Due to the high sensitivity of SAW scales, SpectrumLabs.com highly recommends reviewing all
of the SAW literature prior to running the SAW scale. TFF systems are also compatible with other
scales, including some Ohaus, Mettler and other manufacturers. Please contact Repligen for more
information on scale compatibility.
