Tastant setup
There are up to eight slots for the glass tastant containers with the pre-drilled Teflon caps on top of the
Gustometer (Figure 8). As signified by the blue arrow the inlet tubing connects through the cap of the
bottle to the top Luer inlet port on the Gustometer. From there the fluid goes through the peristaltic
pump. On the back side, each channel has a Luer outlet connector. The eight channel PTFE main tubing
set connects from there to the mouthpiece.
Figure 8 - Up to eight glass containers can be stored on top of the Gustometer
–
one for each channel.
Tastant applicator / Mouthpiece setup
The mouthpiece setup is the most important part of the experimental setup. To assure data quality
during experiments, the mouthpiece must be parallel to the direction of gravity. If the standard
mouthpiece as provided with the Gustometer does not suit the needs experimental requirements,
contact ETT support for a custom design.
Contact ETT for service or replacement of mouth pieces.
Applicator tubing
Proper routing of the PTFE tubing is important, to allow drop formation especially for small delivery
amounts. If mouthpieces are reused, check correct fit after each cleaning cycle and prior each
experiment:
-
Tubing must extend the panel inside the mouthpiece by about 1 mm (bonded in place after
2016)
-
Tubing has no bends or kinks
-
Tubing is free of leaks
-
Tubing Is straight and the ends are cut at a straight angle
Coil mounting (fMRI package)
The ETT Gustometer 2 comes with a standard mounting system for a Siemens 12 and 20 channel clinical
head coil mounts. For other systems we can create a custom fit solution upon request.
