8.
Repeat step 5 with
no fluid reservoir
connected to the inlet tubing to pump air. All water should
be removed from the tubing this way
Cleaning the mouthpiece (tastant applicator)
The mouthpiece is in direct contact with the subject - strict hygiene is very important. The
mouthpiece is designed with materials that allow disinfection with 70% alcohol.
Sufficient hygiene is assured via the following steps:
1.
Thoroughly rinse the mouthpiece with warm running water directly after the experiment,
while rubbing all major particles (saliva, mucus, ...) off the applicator
2.
After the rinsing process the mouthpiece should be kept inside a container of freshly filled
70% Ethanol
3.
After the mouthpiece is essentially clean it should be rinsed in a fresh container of dH2O
4.
The mouthpiece should be dried from outside and inside with clean compressed air.
5.
If the tubing is not dry inside, air should stream through each channel until liquid is removed
from the tubing (pump with Gustometer without liquid reservoir connected)
6.
After the mouthpiece is dry it can be stored in a sealable plastic bag until it is being used
again
7.
Repeat this procedure prior to use if necessary
At this point a thorough, visual inspection is also advised to catch possible defects before you start your
next experiment!
Trouble shooting
•
In case the pump initially does not deliver the liquid all the way through the system, disconnect
a port right before the next part of the tubing filled already. Wait until the air is slowly pushed
out. Additionally, check for leaks or closed valves.
•
If the liquid flow at the mouthpiece seems to be inconsistent, pump longer to remove all the air
from the tubing. Check that no air is entering the system at any.
•
If the flow is still inconsistent check if the tubing on the mouthpiece is accumulating stimulus

Data management
Creating data files
Prior to any experiment a new data file should be created. If not, the data will be appended to the
existing data file. To create a new data file / subject ID tap on
File Manager
in the main window (Figure
and then create new and assign a name und hit ‘confirm’ to finalize
